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 CPU's. 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.
To configure redundant CPU IP addresses using the CLI, use the following
commands from Enable/Configure mode:
(configure)# cpu_redundancy console {slot1 | slot2} <ip
address>
(configure)# cpu_redundancy default-gateway <ip address>
* Note: When the redundant CPU console IP address and default
gateway are assigned and addresses are removed by using the
commands:
> no cpu_redundancy slot1
> no cpu_redundancy slot2
> no cpu_redundancy gateway
The router is no longer reachable and cannot be pinged or used
by the Web Agent from redundant addresses. The initial console
IP address is still usable.
