This chapter provides information about the network topology application and describes how to display your network topology. You have two choices:
Cisco WAN Manager release 9.2 enables you to automatically assign a unique node ID to all nodes in a network. The unique node ID is used to identify nodes in all the different database tables. After installing and configuring CWM 9.2, the unique node ID feature will be active when you launch CWM.
The unique node ID feature of CWM assigns a node identifier to each node as it is discovered. The node IDs for all existing nodes are saved in the nodes.conf file of /usr/users/svplus/config and in the node table of the database. For all subsequent warm starts (where a database exists from the previous session), the nodes are assigned their previous IDs which were stored in the database.
Using the MGX 8850 in stand-alone configurations requires that you disable automatic node ID generation. To assign unique node IDs to stand alone nodes, you must disable automatic Node Identification and use the Topology Configurator feature of the CWM desktop application, CWM Admin, to provide all node information, including the unique node identification, before launching CWM. The Topology Configurator is described in Chapter 8, CWM Administrator. Information about disabling this feature can be found in Disabling Automatic Node ID Generation below.
First add the nodes using the Topology Configurator, then click Apply and Notify to force the topology subsystem to read the nodes.conf file. All nodes for which a Node ID has been defined should display on the Topology map.
To maintain unique Node IDs in your network, you must adhere to the following rules.
To disable automatic unique node ID generation, edit the /usr/users/svplus/config/Topod.conf file. The third line of Topod.conf describes the next line as the Auto Node Id Generation flag. On line four, change the TRUE to FALSE to disable automatic node ID generation.
You can use the Topology Configurator to manually assign all node identification information before launching CWM.
Auto route networks are discovered using link protocol. Before attempting auto route discovery, you must first specify all networks to be discovered in the /usr/users/svplus/config.sv file and add the Node ID for all gateway nodes specified in the config.sv file using the Topology Configurator
The config.sv file is stored in /usr/users/svplus directory. The config.sv file is written with default values during software installation and can have only one line containing 12 fields separated by a pipe ("|") delimiter. Following is an example of the contents of the config.sv file:
0|Network1|nmsbpx01|9600|0|7|6|0|30|1024|9.2|nwip_on|
| Field | Name | Default Value | Meaning |
|---|---|---|---|
1 | CWM Network ID | 0 | Unique identifier for a network |
2 | Network Name | Network1 | Unique name for a network |
3 | CWM Gateway Node Name/ Serial Port | /dev/ttya | Specify the device filename for the serial port used |
4 | Baud Rate Set | 9600 | Serial port speed; must match speed of control port at the node |
5 | Autodial Phone | 0 | Phone number to dial out including prefix, if needed; 0 if not dialing out. |
6 | SV_Timeout | 7 | Link timeout used by svmain (field must not be changed) |
7 | Retransmit | 6 | Link retry count used by svmain (field must not be changed) |
8 | DL_Throttle_TO | 0 | Download throttling timeout (field must not be changed) |
9 | DL_Ack_TO | 30 | Acknowledge timeout for download (for configd) |
10 | DL_Blk_SIZE | 1024 | Block size for download (for configd) |
11 | Switch Release | 9.2 | Switch release number |
12 | nwip_flag | nwip_on | Flag to indicate in band (nwip_on/nwip_off) or out of band (lan_ip) |
Add the Node ID for all gateway nodes specified in the config.sv file using the Topology Configurator. You can add the Node ID for other nodes later, perhaps while auto route discovery is taking place.
First add the nodes using the Topology Configurator. When you have finished adding nodes, click Apply, then Notify. Doing so forces the topology subsystem to read the nodes.conf file. All nodes for which a Node ID has been defined should display on the Topology map.
To display the CWM Network Topology window, start the CWM application, enter 3 (Start Desktop) at the Main Menu prompt and press the Return key, then click on the Topology button in the CWM Desktop window. (For a full description of starting CWM and the CWM Desktop, see Chapter 2 "Starting and Stopping Cisco WAN Manager".)
Two windows are displayed, the CWM Network Topology window and the Overview window. Both windows display your network's nodes and trunks.
The CWM Network Topology window is shown in Figure 3-1. You perform all menu options and map manipulations through this window. A minimal amount of user interaction is allowed through the CWM Network Topology window.
The Overview window provides a constant view of the entire topology at all times, regardless of the zoom/pan level in the CWM Network Topology window. This provides you a reference point as you pan around and zoom in or out in the CWM Network Topology window. A dotted rectangle in this window identifies the visible area of the CWM Network Topology window. When you click the mouse on this rectangle and drag it to a new location, the view in the CWM Network Topology window changes to show the region now enclosed within the rectangle. (In Figure 3-2, the rectangle surrounds the entire map, as the CWM Network Topology window is zoomed out to show the entire topology.)
The CWM topology application includes basic menu options, as well as options that are enabled when a node is selected. Other applications are the alarm indicators (sound and color) which provide timely indications of network status.
To select objects in the CWM Network Topology window, position the cursor over the object and click the left mouse button.
Alternatively, when you press the Shift key while dragging a selection rectangle around multiple nodes/trunks, all nodes and trunks within the rectangle are selected when you release the mouse button. (When you don't continue to press the Shift key, the drawn rectangle identifies a zoom region.)
To zoom in on a specific area of the CWM Network Topology window, drag a selection rectangle around it by holding the mouse button down and dragging the cursor. When you release the mouse button, the view zooms to fill the window with the selected area.
Zoom back out by selecting the View menu's Restore option, or by resizing the window.
You can also use the View menu's Zoom In and Zoom Out options. This performs the zoom operation by a constant factor of two.
To move a node within the CWM Network Topology window, select the node, then without releasing the mouse button, drag it to the desired location.
You can pan the topology view by using the window's scrollbars, or you can drag the Overview window's view rectangle around the Overview map. When you release the mouse button, the view in the CWM Network Topology window changes to display the region identified by the Overview rectangle.
Double-clicking on a node displays a submap, showing all components associated with the selected item, such as feeders of routing nodes. You can select a node or trunk in this submap to perform other operations appropriate to the type of object---add a comment to a trunk or administer a node, for example. Double-clicking on a group icon in the CWM Network Topology window displays the Group Node List window, which lists the member nodes.
When the line connecting two nodes in the CWM Network Topology window represents multiple trunks, the line appears thicker on the topology map. When you click on this thick line, a window is displayed with a list of individual trunk connections. Select the desired trunk to display a window allowing you to specify a trunk comment.
When you double-click on a routing trunk icon, the Display Trunk window is displayed. This window provides status and attribute information about the trunk. Select a row in the grid then click on the Comment button to add a comment (up to a maximum of 255 characters) about the trunk via the Trunk Comment window.
The following sections provide information about the topology window's menus. The menu descriptions are displayed in the same order as they appear (from left to right) in the CWM Network Topology window.
This section describes the options of the File Menu.
Select this option to save the current map configuration. The next time the topology is displayed, the saved configurations are used.
Select this option to print the current map. The defaults are to print a color image of the entire map. When you select the print option, the Print Dialog window is displayed as shown in Figure 3-3.
When printing a topology map, you have the following options.
Select this option to exit the CWM Network Topology window without shutting down the CWM processes. CWM continues to collect data even though the workstation screen is cleared of the CWM Network Topology and Overview windows.
Select this option to display a submenu with the following options:
Select this option to display a list of available maps. Select a map image, then click on the OK button to make the selected map the CWM Network Topology window's background image (displayed only when the Background selection on the Layer submenu is toggled on).
Select this option to zoom in on the current view by a factor of two.
Select this option to zoom out from the current view by a factor 1/2.
Select this option to restore the topology view to its original state (entire map is displayed).
You must first select the node(s) you want to add to a group. Select nodes by clicking on them in the CWM Network Topology window or drawing a selection rectangle around them (hold the Shift key and the mouse button down simultaneously while you drag the mouse) or press the Shift key while clicking on individual node(s).
With the node(s) selected, select this option to display the Group Add Node window. A list of existing groups are displayed (when any exist).
To create a new group with the currently selected nodes, specify a new name in the New Group Name field, then click on the Apply button.
To add the selected nodes to an existing group, select the group name from the list, then click on the Apply button.
Click on the Cancel button to close the window without taking any action.
To remove an individual node from a group, first select the group's icon in the CWM Network Topology window, then select this option. The Group Delete Node window displays a list of the selected group's nodes. Select one or more of the nodes, then click on the Apply button to remove them from the group.
Select a group or multiple groups by clicking on their icons or drawing a selection rectangle around them using the mouse. Then select this option to delete the groups from the CWM Network Topology window.
When a group is deleted, nodes of its members are displayed in their original locations in the CWM Network Topology window.
Displays a list of all nodes in the selected group.
Displays a list of all trunks in the selected group.
Select this option to display a submenu with the following options:
With a node selected in the CWM Network Topology window, select this option to display a submenu with the following options:
Select this option to display a submenu containing the following selection:
Select a node, then select this option to view the list of current software images available for that node. The images shown in the Image DownLoader window, shown in Figure 3-9, are available from the CWM hard disk.
Select an image from the displayed list, then click on the DownLoad button to load that image into the device.
Click on the Abort button to stop an in-progress download.
Click on the Close button to dismiss the window.
During node initialization, the node attempts to locate the correct version of software, firmware, or image from Flash EPROM. When the image is not located, the CWM workstation is then interrogated. Failure to find the image at the CWM workstation results in interrogation of other nodes on the network. When the system is unable to locate the image, you may need to download or restore the image. The SW/FW menu option enables software and firmware downloads and restoration of previous node configurations. Downloading commands are issued from the Node Administration window. Contact Cisco Customer Support for further information.
The CWM DownLoader simplifies the distribution of software and card firmware to nodes in the field. This is accomplished by providing download capability from a single point to an entire network.
You can download software from one of the following places:
To store a software release (image), you copy the BPX 8600 series (BCC) software release from tape to the CWM workstation's hard disk.
A list of the stored software images can then be viewed from the CWM Network Topology window via the SW/FW option on the Software Mgmt menu. Images can then be loaded to system nodes by using commands at the Node Administration window.
Select this option to display a submenu with the following options:
See Chapter 15, "Saving and Restoring Node Configurations", for information about saving and restoring node configurations. See Appendix A, "Save and Restore Configuration Commands", for information about the commands used to save and restore node configurations.
Select this option to launch the configuration restoration program documented in Chapter 15, "Saving and Restoring Node Configurations". See Appendix A, "Save and Restore Configuration Commands", for information about the commands used to save and restore node configurations.
Select this option to display the Help on Color window. This window defines the meanings of the colors used in the CWM Network Topology window.
Select this option to display the Help on Icon window. This window identifies the icons used in the CWM Network Topology window (icons, including the line patterns identifying specific trunk types, are different in HP OpenView).
All 3810 devices connected to a particular routing node are grouped together in a cluster and shown on the topology by a single icon. This icon is assigned a default name Cluster. An IP address is not displayed for this icon.
The color of the cluster's icon shows the status of the individual device with the most severe alarm condition. For example, when four 3810s exist in a cluster and one of them is unreachable, while the other three are in a minor alarm state, the color of the cluster icon shows it to be unreachable. The alarm status of a trunk connecting either a 3810 cluster on the main map or a 3810 device on the submap is the same as that of the node. CWM does not receive a separate alarm status for the trunk. Therefore, when the cluster or individual device is unreachable, the trunk is shown with a major alarm.
Double-click on the 3810 cluster's icon to display a submap showing the individual 3810s connected to the parent routing node. An icon representing an individual 3810 in the submap displays the node's name and IP address.
To close the submap, select the submap File menu's Quit option. To administer a node, select it in the submap window, then select the Node option from the submap's Component menu, and then the Admin option from the subsequently displayed submenu.
You can select a node and drag it to a new location on the submap, however, this position is not saved even when you save the topology view.
Node status is not updated in a submap view once the window has been displayed. To check the current status of nodes, you must close and redisplay the submap.
CWM Topology supports discovery of MC 3810 devices attached to an AUSM port running ILMI. (ILMI). CWM processes detect the MC 3810 device and gather information from it such as the IP address and MGX 8820 slot and port number. This information is sent to CWM Topology where the 3810 device is added to the network.
After the MC 3810 is added to the network and more information is gathered, a node ID is assigned, and information about the device is stored in the Informix database. During a cold start of CWM, CWM receives MC 3810 information from the MGX 8820 configuration files.
The Topology system will query MC 3810 devices and other routers for the following MIB objects:
.iso.org.dod.internet.private.enterprises.cisco.ciscoProducts.157
The CWM Topology application displays MC 3810 devices in maps and sub-maps, including the device's IP address and node name. CWM Topology also updates the MC 3810 device's status when any of the following events occur:
Figure 3-12 shows a topology map of a network managed by CWM. The node named svigx02 has a cluster of MC 3810s connected to it.
Double-click the mouse on the svigx02 node to display a submap as shown in Figure 3-13. By default, less than five MC 3810 devices will each be displayed; five 3810s will appear as one cluster.
You can modify the environmental variable CLUSTER_NODE_THRESHOLD to change the number of 3810s required to display a cluster with a command like the following:
setenv CLUSTER_NODE_THRESHOLD 3
The command above would display three MC 3810s as a cluster. Double-click the cluster icon to display all connected MC 3810 devices.
Left click on a 3810 icon to select it, then right click to display a menu of options, as shown in Figure 3-15.
The syslog Trap Generator supports MC 3810 devices, sending a message if any of the following changes occur:
The Informix Online database is updated with information about the MC 3810 device's node and access_node tables when any of the following events occur:
An ILOG message is sent to emc when any of the following events occur:
CWM 9.2 provides limited support for virtual switch interfaces (VSI). A virtual switch interface is an interface defined for interaction between a controller and a Cisco WAN switch. VSI is used to control Cisco WAN switch resources via the connection routing system (auto Route or PNNI) in a VSI controller. In a VSI-enabled network, different virtual networks may be overlaid on top of the physical WAN switches.
CWM 9.2 provides the following support of VSI for tag switch controllers (TSC) only:
CWM receives information about the VSI partition by way of robust messages. CWM uses the trunk information from the network routing system to identify both ends of a VSI trunk and to perform VSI resource partition consistency checking.
To display VSI resources, double-click on a node in the Topology map that contains a VSI controller. Doing so launches a Topology submap, as shown in Figure 3-16.
The VSI Resource Partition Display is essentially the view of a virtual switch and displays controller resources and statistics of the designated interfaces. The controller frame provides a summary of the controller information of the virtual switch including the name, IP address and the associated partition ID. Each row in the VSI Resource Partition frame represents a specific interface designated in the form
nodename: slot.port(.vtrkID)
Each row represents a VSI interface managed by the named controller. The following statistics are displayed:
Figure 3-17 shows an example of the VSI Resource Partition Display.
CWM 9.2 uses the VSI partition data from each end of a virtual trunk to perform consistency checking on demand. The VSI partition data on both ends of a VSI interface should be exactly the same. When you select Network > VSI Consistency Check from the Component Menu of the topology map, CWM gathers the VSI Partition data and displays it in the VSI Partition Consistency Checking Display, as shown in Figure 3-18.
The VSI Partition Consistency Check display indicates summarized error information such as the number of errors found after the completion of a VSI partition consistency check and the number of single-end interfaces in the Error frame.
The VSI Trunk End Partition Info frame displays information about individual VSI interfaces as shown in the VSI Resource Partition display. CWM displays the trunk end information in the first column. The format of the trunk end information is:
nodename1: slot.port(.vtrkID): partition1
- nodename2: slot.port(.vtrkID): partition2
A pair of rows displays a VSI interface's partition consistency checking results. If both ends have the same values for a given parameter, the value is shown in the first row only. If the values differ, both are shown in red to flag the inconsistency. If CWM cannot determine one end of an interface, a row is inserted and displayed in yellow to indicate data is missing.
Routers in the network must be manually configured to send syslog messages to the correct destination. You can configure using the command line interface (CLI) or programmatically through SNMP calls.
When a router configured to send syslog messages to the CWM workstation where STG is running sends a message, the STG receives it and processes the message, parses it, and logs the message in a database.
Before using the STG, all routers in the network must be configured to send the syslog messages to the CWM workstation where STG is running. To configure routers to send syslog messages, complete the following steps:
Step 6 Either telnet or rlogin to the router, then enter the following:
host > enable
Step 7 Enter the required password.
Step 8 Enter the following commands:
host# configure terminal
host(config)# logging on
host(config)# logging <destination IP address>
When first activated, the STG reads a configuration file stored at /usr/users/svplus/stg.conf. Table 3-2 lists the STG configuration file parameters and default values. Edit the stg.conf file using vi or another UNIX text editor.
| Parameter | Description |
|---|---|
SYSLOG_MESSAGE_LOG_FILE | /usr/users/svplus/config/syslog.log |
STG_DIR |
|
NUM_OF_MESSAGE_QUEUES | 15---Number of message queues to be created by the STG |
SYSLOG_MESSAGE_WRAP_COUNT | 1000---Number of messages stored in the log file before the file is rolled over |
NODE_INFO_FILE | /usr/users/svplus/config/nodeinfo.dat |
ROLL_OVER_FILE | /usr/users/svplus/config/syslog_rollover.log |
KEEP_ALIVE_TIME_PERIOD | 5---Frequency of keep alive messages sent to routers in the network; alarms are generated if a router is unreachable |
DEBUG_LEVEL | 5---Level of debug messages to be logged by STG |
INTERNAL_CACHE_FILE | /usr/users/svplus/config/stg_internal_cache.log |
You must configure the syslogd daemon to log messages received from routers in the network to a specific location where STG can read the syslog messages. Two parameters specify the relative path for the syslog message file, STG_DIR and SYSLOG_MESSAGE_LOG_FILE. These parameters must be set in the /etc/syslog.conf file, and the following line must appear in the file.
local7.debug /usr/users/svplus/<STG_DIR>/<SYSLOG_MESSAGE_LOG_FILE>
The node information file, nodeinfo.dat in the $SVHOME/stg directory, is specified by the STG configuration parameter NODE_INFO_FILE. This file contains information about all nodes discovered by the Topology subsystem. If STG is stopped and started again, the node information file is read for any 3810 information or information about other routers.
The node information file has the following format where each field is separated by a tab:
15505<3810IP address><3810 name>12
where:
| Field | Meaning | Comments |
|---|---|---|
1 | Node Operation | 155 = Add node |
2 | Network ID | (not used at this time; always 0 |
3 | Node ID | (not used at this time; always 5) |
4 | IP address of node |
|
5 | Name of 3810 |
|
6 | IOS version running on nodes |
|
UNIX system software sends syslog messages to the system console (and possibly a logging server or other systems in the network) during operation. Not all system messages indicate problems; some messages are informational, while others provide information to help diagnose problems with communications lines, internal hardware, or system software.
System error messages begin with a percent sign (%) and are structured as follows:
%FACILITY-SUBFACILITY-SEVERITY-MNEMONIC: Message text
FACILITY---a code consisting of two or more uppercase letters that indicate the facility to which the message refers. A facility can be a hardware device, a protocol, or a module of system software.
SUBFACILITY---
SEVERITY---a single-digit (0-7) that reflects the severity of the condition. The lower the number, the greater the severity. A zero (0) condition indicates an emergency due to an unusable system. Table 3-3 lists the eight severity levels and their meanings.
| Level | Description |
|---|---|
0 | System unusable |
1 | Immediate action needed |
2 | Critical condition |
3 | Error condition |
4 | Warning condition |
5 | Normal, but significant condition |
6 | Informational messages only |
7 | Appears during debugging only |
MNEMONIC---
Message Text---a text string describing the condition and sometimes containing detailed information about the event, including terminal port numbers, network addresses, or addresses that correspond to locations in the system memory address space. Because the information in these variable fields changes from message to message, it is represented here by short strings enclosed in square brackets ([xyz]). For example, a A decimal number is represented as [dec]. Table 2 lists the representations of variable fields and the type of information in them.
| Representation | Type of Information |
|---|---|
[atalk_address] | Appletalk address |
[atalk_net] | Appletalk network, either 600 or 600-601 |
[char] | Single character |
[chars] | Character string |
[dec] | Decimal number |
[enet] | Ethernet address |
[hex] | Hexadecimal number |
[inet] | Internet address |
[int] | Integer number |
[node] | Address or node name |
[sci_notation] | Scientific notation |
[t-line] | Terminal line number in octal |
[v-name] | VINES name or number |
Sore error messages also indicate the card and slot reporting the error.
%CARD-SEVERITY-MSG:SLOT
CARD---a code that describes the type of card reporting the error; VIP and FEIP are possible card types.
SEVERITY---a single-digit (0-7) that reflects the severity of the condition, as listed in Table 3-3.
MSG---a mnemonic that indicates this is a message, always shown as MSG.
SLOT---indicates the slot number of the card reporting the error; It is shown as SLOT followed by a number, as in SLOT5.
To display your network topology using the a HP OpenView (HP OV) application, you must do the following:
From the other C-shell window:
Step 1 For example, from a C-shell window, invoke the HP OpenView application:
host% /opt/OV/bin/ovw
An About OpenView window is displayed. You can click on the Close button to dismiss this window, or you can wait for it to be dismissed when the OpenView Root window, shown in Figure 3-19, is displayed.
Step 2 Double-click on the CWM icon to display the CWM HPOV Network Topology and Panner: Network CWM Topology windows. Both windows display your network's nodes and trunks.
Step 3 From the pull-down menus, you can launch all of the CWM features. Note, many menu items are disabled until an appropriate element is selected, for example, a node in the topology.
The CWM HPOV Topology window is editable and all menu options, as well as map manipulations, are performed through this window. You click on the "home" icon to return to the Root window. You click on the "up-arrow" icon to return to the previously displayed CWM HPOV Topology window.
The Panner window, provides a constant view of the entire topology at all times, regardless of the zoom/pan level in the CWM HPOV Topology window. This provides you a reference point as you pan around and zoom in or out in the CWM HPOV Topology window.
A dotted rectangle in the Panner window identifies the visible area of the CWM HPOV Topology window. When you click the mouse on this rectangle and drag it to a new location, the view in the CWM HPOV Topology window changes to show the region now enclosed within the rectangle.
The HP OpenView topology application includes basic menu options, as well as options that are enabled when a node is selected. Other applications are the alarm indicators (sound and color) which provide timely indications of network status.
