This chapter provides information about configuration required for the CWM workstation.
CWM 10.3 supports networks running multiple network discovery protocols such as AutoRoute and PNNI. This section also includes information required to configure stand-alone nodes.
To configure the CWM workstation to use AutoRoute discovery, modify the network.conf file in the /usr/users/svplus/config directory as shown in the following example.
 |
Note The network.conf file example below is for a machine named nmsbpx02 on a network designated network1. |
NETWORK:network1 GATEWAYS:nmsbpx02 DISCOVERY PROTOCOL:AUTOROUTE IP REACHABILITY FLAG:NWIP_ON OPTIONAL:"TIMEOUT=7, RETRANSMIT=6, THROTTLE=0, ACKNOWLEDGE=30, BLOCKSIZE=1024"
Use the Topology Configurator to provide information required to communicate with the nodes. Also use the configurator to specify Network IP.
|
Note These are nodes that have their SNMP community string for GET operations not set to public, and SNMP community string for SET operations not set to private. |
To configure a PXM45 card, telnet to the card and execute the following commands:
pxm45> shmsimulateresetReason 0 pxm45> deltree "C:DB2"
|
Note The above commands should be used when inconsistency exists between the database and the image. |
anotherPXM> addcontroller 2 i 2 7 "pxm45 controller"
|
Note The step above is only required after a dbtree or clrallcnf command. |
anotherPXM> addpnport 9:1.1:1 assumes an AMXSM in slot 9 anotherPXM> cnfpnportsig 9:1.1:1 -nniver pnni 10
To configure a AXSM card, telnet to the card and execute the following commands:
specificAXSM.a> cnfingsct -sct 5 specificAXSM.a> upln 1.1 specificAXSM.a> addport 1 1.1 9600 96000 5 2 specificAXSM.a> addpart 1 1 2 9600 96000 9600 96000 33 4095 33 65535 3 512 specificAXSM.a> cnfilmi -if 1 -id 1 -ilmi 1 -trap 1 specificAXSM.a> dspports specificAXSM.a> dspparts specificAXSM.a> dspilmis specificAXSM.a> cc 7 assumes PXM card is in slot 7 specificAXSM.a> dsppnports specificAXSM.a> uppnport 9:1.1:1 specificAXSM.a> ipifconfig atm0 <ipaddress node NWIP> specificAXSM.a> cnffname <sysname> MGX 8850 node name, for example
In a stand alone environment, the network.conf file does not require modification. Use the Topology Configurator to provide the following information:
To add a new node, complete the following steps:
Step 2 Select Node from the Edit menu.
Step 3 Select Add from the Node menu.
Step 4 A Node Dialog box appears after selecting Add from the Node menu. The Node Dialog box contains two tab windows, Node and Mode, in which the user enters information about the new node.
Step 5 In the Node window enter the new node name, the node Descriptor information, and FTP information, in the appropriate fields.
Step 6 In the Mode window enter the Mode, (Connected or Stand Alone), the MGX Model, the IP Address, and any Parent Information, including Feeder Slot, Feeder Port, Parent Name, Parent Slot, and Port.
Step 7 Press the OK button in the Node Dialog box.
The Network Configurator validates the new node by ensuring its IP address and unique node name. The node will be displayed in the Network Configurator main window if the node information is valid.
Step 8 Select close from the Node Dialog pull down menu, located in the upper left hand corner of the window.
Step 9 Select File, then Save from the Network Configurator Window.
|
Note Changes made using the Network Configurator are not saved in the node_info table until you press the Save button. If the Cancel button is pressed, no changes will be made to the node_info table. |
All MGX 8850 nodes will be displayed in both the standalone view and the integrated view.
At the CWM workstation, log in as user root, and examine the following files.
|
Note The IP addresses shown are examples. Use addresses relevant to your network. |
Examine the /etc/hosts file and check all nodes' IP LAN addresses, IP relay addresses, and node names. To view the /etc/hosts file, enter the following command:
host% more /etc/hosts
Following is an example of the /etc/hosts file:
209.165.200.225 <tab> igx2 loghost 10.10.10.225 <tab> igx2-r
The first two lines show a node's LAN IP address. The third line shows an IP-relay address. If possible, use the same last octet value for NWIP as the LAN IP address.
Examine the /etc/netmasks file for all subnet and netmask entries. All subnet and netmask entries should be listed. To view the /etc/netmasks file, enter the following command:
host% more /etc/netmasks
The workstation's address will already be listed. Add the NWIP address and subnet mask as shown in the following example:
209.165.200.225 <tab> 255.255.255.0 10.10.10.0 <tab> 255.255.255.0 (This line will be needed.)
Examine the /etc/rc2.d/S72inetsvc file to ensure that the IP relay address points to the gateway node. To view the /etc/rc2.d/S72inetsvc file, enter the following command:
host% more /etc/rc2.d/S72inetsvc
Use the vi editor to open the S72inetsvc file and find the following line:
/usr/sbin/route add -interface -netmask "224.0.0.0" "224.0.0.0" "$mcastif" )&
Add the following line directly below that line:
/usr/sbin/route add net 10.10.10.0 209.165.200.225 1 (use your site's valid IP addresses)
|
Note When using the vi editor, remember to write your changes before quitting. To save your changes while using the vi editor, remember to press Esc, colon (:), then wq!. |
Examine the /etc/defaultrouter file. To view the /etc/defaultrouter file, enter the following command:
host% more /etc/defaultrouter
If it is not currently in the file, use the vi editor to add a line containing the IP address of the default router to which the CWM workstation is attached.
|
Note When using the vi editor, remember to write your changes before quitting. To save your changes while using the vi editor, remember to press Esc, colon (:), then wq!. |
Examine the /usr/users/svplus/config/network.conf file. Check for the mnemonic of the gateway node. Also, for BPX/IGX, check the IP Reachability Flag:
To view the /usr/users/svplus/config/network.conf file, enter the following command:
host% more /usr/users/svplus/config/network.conf
|
Note Use only one Gateway per network in case of AutoRoute networks. |
NETWORK:Network1 GATEWAYS:nmsbpx12 DISCOVERY PROTOCOL:AUTOROUTE IP REACHABILITY FLAG:NWIP_ON OPTIONAL:"TIMEOUT = 7, RETRANSMIT = 6, THROTTLE = 0, ACKNOWLEDGE = 30, BLOCKSIZE = 1024"
Table 6-1 provides a list of the parameters in the network.conf file.
| Parameter Name | Default Value | Description |
|---|---|---|
TIMEOUT | 7 | Link timeout value. The amount of time to wait before resending a message to an IGX 8400/BPX 8600 when a response is not received. This field must not be changed. |
RETRANSMIT | 6 | Link retry count. The number of times CWM will retransmit a message before it declares the link down. This field must not be changed. |
THROTTLE | 0 | Download throttling timeout value. This field must not be changed. |
ACKNOWLEDGE | 30 | ACK timeout value used during the download process. When an acknowledgment to a configuration message sent to an IGX 8400 or BPX 8600 is not received within this time period, the message is sent again. |
BLOCKSIZE | 256 | Block size used for an IGX 8400 or BPX 8600 configuration upload. |
|
Note PNNI networks do not use the IP REACHABILITY and the OPTIONAL parameters. |
NETWORK:Network2 GATEWAYS:nmsbpx01,nmsbpx11 DISCOVERY PROTOCOL:PNNI
Change directory to /system and enter the ls command. Check to see that all required HPOV PSOV_XXXXX patches have been installed.
# cd /system # ls
Check to see that the CWM installation process added the required semaphores. Use the vi editor to open the /etc/system file, go to the bottom of the file, and confirm that the following lines have been added:
forceload: sys/shmsys forceload: sys/semsys set semsys:seminfo_semaem=16384 set semsys:seminfo_semmap=66 set semsys:seminfo_semmni=4096 set semsys:seminfo_semmns=4096 set semsys:seminfo_semmnu=4096 set semsys:seminfo_semume=64 set semsys:seminfo_semvmx=32767 set semsys:seminfo_semmsl=30 (This is a lower case L in semmsl) set shmsys:shminfo_shmmax=268435456 set shmsys:shminfo_shmmin=100 set shmsys:shminfo_shmmni=100 set shmsys:shminfo_shmseg=100
|
Note These changes will not take effect until after the CWM workstation has been rebooted. |
After completing the configuration, reboot the workstation.
# sync ;sync ;reboot
IGX 8400 and BPX 8600 nodes require that you modify the SNMP Community string.
|
Note The SNMP Community string cannot be changed in BPX-SES, MGX 8220, MGX 8230, MGX 8250, and MGX 8850 switches. |
For example, in the nodes:
host% cnfsnmp <getme> <setme> <trapme>
You must modify two files on the CWM workstation in directory /usr/users/svplus/config:
As user root on the CWM workstation, edit the /usr/users/svplus/config/svplus.conf file and set SV_COMMUNITY to getme and set SV_SETCOMMUNITY to setme.
The svplus.conf file should look like the following example:
# Community name for BPX and IPX # SV_COMMUNITY=getme SV_SETCOMMUNITY=setme
|
Note When using the vi editor, remember to write your changes before quitting. To save your changes while using the vi editor, remember to press Esc, colon (:), then wq!. |
As user svplus on the CWM workstation, edit the /usr/users/svplus/config/process.conf file. The process.conf file should have a line like the following example:
cmgrd on . cmgrd -c setme -C getme -i 5
|
Note When using the vi editor, remember to write your changes before quitting. To save your changes while using the vi editor, remember to press Esc, colon (:), then wq!. |
