This chapter descibes the configuration procedures for the EtherChannel, Neighbor View, and Trap Receiver Table applications.
To start the EtherChannel application, select Tools>EtherChannel Configuration.
To start the Neighbor View application, select Tools>Neighbor View.
To start the Trap Receiver Table application, select the device, select Configure>device, and select the Trap Receiver Table category.
EtherChannel is a high-bandwidth connection between two Catalyst 5000 series or 3000 series switches. An EtherChannel is a grouping of two switch devices that behave as a single switch.
Each Catalyst 3000 series switch EtherChannel is comprised of two to seven ports, to provide a bandwidth from 20 to 80 Mbps in half-duplex mode, or from 40 to 160 Mbps in full-duplex mode.
You can create an EtherChannel only between two Catalyst 3000 series switches and not between a Catalyst 3000 series switch and a workstation.
Ethernet channels can be created using the ports within the same group (for example VLAN). To add an EtherChannel between two Catalyst devices, you specify the ports that you will connect. The Catalyst treats the port with the lowest number as the primary port.
For example, if an EtherChannel consists of ports 8, 11, and 13, the primary port is 8. Broadcast, multicast, and unknown destination packets are forwarded first to the primary port in an EtherChannel. The primary ports of both EtherChannels must be connected to each other. For example, if an EtherChannel links ports 8, 11, and 13 of one device and ports 3, 6, and 9 of another device, ports 8 and 3 must be connected to each other.
When you click Configure from the Ethernet Channelling category, the Configure EtherChannel window is displayed (Figure 9-1). The Configure EtherChannel window allows you to perform the following:
The following action buttons may be available:
Each Catalyst 5000 series switch EtherChannel is comprised of two to seven ports, to provide a bidirectional bandwidth of up to 800 Mbps. The module ports are divided into three groups:
Ethernet channels can be created using the ports within the same group, and with the following combinations only:
For example, ports 7 and 8 cannot be channelled without ports 5 and 6, and ports 1 and 2 cannot be channelled with port 3 alone.
When you click Configure from the Ethernet Channelling category, the Configure Ethernet Channel window opens. This window allows you to designate channelled ports. The information is shown in the form of a table and each entry consists of the following:
Port configuration of each group is through pop-up menus. There are four possible combinations listed as choices in the pop-up menus, including the following:
To ensure optimum EtherChannel functionality, you must consider the following items:
This section contains configuration procedures for EtherChannel connections.
This section contains procedures for EtherChannel connections for Catalyst 3000 series switches. To configure the EtherChannel connections, perform the following steps:
Step 1 Enable channelling on the ports.
Step 2 Ensure that the following configuration applies to all ports belonging to a channel, at both ends of the channel:
Step 3 Select Tools >EtherChannel Configuration. This brings up the Configure EtherChannel window.
Step 4 To set up an EtherChannel, perform the following:
(a) Select the channel and switch number from the list, select the ports you want in the channel in the CiscoView window, and drag them (holding down the middle mouse button for UNIX systems or holding the left mouse button for PC systems) onto the channel list.
(b) Repeat for an equal number of ports on another switch.
(c) Drag those ports (holding down the middle mouse button for UNIX systems or holding the left mouse button for PC systems) to the channel with the same number on that switch.
(d) Connect the two switches with the appropriate cables on the selected ports.
Step 5 To configure the EtherChannel, perform the following as appropriate:
(a) To highlight ports of a channel in color, select a channel and the color desired. To clear the color assignment, select the channel and click Hide.
(b) To add a port to a channel, select a channel from the list (holding down the middle mouse button for UNIX systems or holding the left mouse button for PC systems) and drag the port onto the channel list.
(c) To add all the ports in the channel, select the channel, and then click Selection. In the Modify Selection box, select Add this channel's ports to the selection and click OK.
(d) To clear a channel assignment, select the channel from the list and click Evacuate.
(e) To remove all the ports in a channel from selection, select the channel, and then click Selection. In the Modify Selection box, select Delete this channel's ports and click OK.
This section contains procedures for EtherChannel connections for Catalyst 5000 series switches. To configure the EtherChannel connections, perform the following steps:
Step 1 Enable channelling on the ports.
Step 2 Disable the spanning tree on the channelled ports of the VLAN.
Step 3 Ensure that the following configuration applies to all ports belonging to a channel, at both ends of the channel:
Step 4 Select Tools>EtherChannel Configuration. This brings up the Ethernet Channel Configuration window.
Step 5 Click Show Channel to display frames around same Ethernet Channel ports, or Hide Channel to hide the frames; default is Show Channel.
Step 6 Click Configure to configure EtherChannel. This brings up the Ethernet Channel Configuration window.
Step 7 Click the right mouse button in the appropriate Card and Group field to display the pop-up window, and select the port combinations as appropriate.
Step 8 Click Modify to commit your input and exit the window.
This section contains the descriptions and configuration procedures for the Neighbor View application.
Neighbor View provides a way to display the Cisco Discovery Protocol (CDP) cache table as part of device configuration. This feature does not allow you to continuously monitor the CDP cache information. The values are retrieved only once and not updated periodically. To see the update(s), click Refresh.
To invoke Neighbor View, select Tools>Neighbor View. This brings up the Neighbor View window (Figure 9-3).
The following action buttons may be available:
The CDP Parameter Configuration window (Figure 9-4) allows you to either apply the parameter values to any one local port by selecting an entry, or apply the parameter values to all the ports.
To configure the local port-specific CDP parameters, perform the following steps:
Step 1 Select Tools>Neighbor View.
Step 2 Select a port, and then perform one of the following:
(a) Click Modify Selected Port if only a specific port is to be configured.
(b) Click Modify All Ports if all ports are to be configured the same.
Step 3 Within the displayed CDP Configuration window, perform one of the following:
(a) Select the state and enter the interval (in seconds) at which CDP messages are generated on this interface. Click OK to commit the changes and exit the window.
(b) Click Default to return to the default values, and then click Cancel to exit the window.
This section covers only the Trap Receiver Table application for the Catalyst 3000 series switches; the Trap Receiver Table application for the Catalyst 5000 series switches will be covered in a later release.
To invoke the Trap Receiver Table, select Tools>Trap Receiver Table.
The Trap Receiver Table window (Figure 9-5) contains information about the Simple Network Management Protocol (SNMP) managers on the network that are set up to receive traps, and contains action buttons.
The action buttons are as follows:
