Configuring Supervisor Module Redundant Ethernet Console IP Addresses

Web Agent Procedure

If you need to communicate with both the Active and Standby Supervisors, configure an alternate Ethernet Console IP address for both. Configure an alternate IP address for both slot 1 and 2 CPUs, by using the Web Agent or the CLI.

Note: Do not Login to a Standby Supervisor module to manage the switch. The Standby Supervisor does not have accurate switch status information until it becomes the Active Supervisor.

To identify the Active or Standby supervisor, look at the LED display (marquee), or open the System > Configuration > CPU Redundancy > Status/Statistics folders from the Web Agent, or use the show CPU status CLI command.

To configure a redundant console IP address by using the Web Agent:

1. In the navigation pane, expand the System > Configuration > CPU Redundancy folders, and then click Configuration. The CPU Redundancy Configuration Web page is displayed in the content pane. See Figure�89.

Figure�89:�CPU Redundancy Configuration Web Page

2. Enter the internal IP addresses of the slot 1 and slot 2 CPUs in the Redundant CPU Console IP Address field. The addresses cannot be the same as the console IP or each other. The Gateway must be on the same subnet as the IP addresses. This sets the IP addresses for the Ethernet Consoles in slot 1 and slot 2 CPUs. The default values are 0.0.0.0.
3. Enter the redundant CPU default gateway IP address in the Redundant CPU Default Gateway field. This is the default gateway that the standby Ethernet console IP interface uses. It does not have to match the Active CPU's default gateway. The default value is 0.0.0.0.
4. The Switch MAC Prefix field displays the configured MAC prefix used to build the local MAC address for each routing interface. The first 36 bits of the switch MAC prefix make up the first 36 bits of this local MAC address. If the startup.txt does not set the switch MAC address, the supervisor's MAC address is used. Resetting this will cause it to be restored to the supervisor's MAC address. Only the Active supervisor uses this value. The default value is the manufacturer's supervisor MAC address.
5. Click APPLY to save your changes,
6. RESET SWITCH MAC PREFIX to reset the MAC prefix on your switch.
