MSFC Redundancy
The designated MSFC is configured first. This example shows a missing alternate configuration for the
VLAN 1 interface:
Router-16# configure terminal
Enter configuration commands, one per line.
Router-16(config)# redundancy
Router-16(config-r)# high-availability
Router-16(config-r-ha)# config-sync
Alternate IP address missing for Vlan1
The alternate configuration is missing. The auto-config sync can not be enabled
Note When specifying the alternate IP configuration, the configuration that is specified before the alt keyword
relates to the MSFC on the supervisor engine in slot 1 of the switch; the configuration that is specified
after the alt keyword relates to the MSFC on the supervisor engine in slot 2. See the
Usage" section on page 23-36
This example shows how to specify the alternate configuration for VLAN 1:
Router-16(config)# interface vlan 1
Router-16(config-if)# ip address 70.0.70.4 255.255.0.0 alt ip address 70.0.70.5
255.255.0.0
Router-16(config-if)# exit
This example shows that high-availability redundancy is accepted:
Router-16(config)# redundancy
Router-16(config-r)# high-availability
Router-16(config-r-ha)# config-sync
Router-16(config-r-ha)# end
Router-16#
00:03:31: %SYS-5-CONFIG_I: Configured from console by console
Because the Config Sync AdminStatus on the nondesignated MSFC is disabled, the Config Sync
RuntimeStatus on the designated MSFC will remain in disabled mode. The following message is
displayed on the designated MSFC:
00:17:05: %RUNCFGSYNC-6-SYNCEVENT:
Non-Designated Router is now online
High-Availability Redundancy Feature is not enabled on the Non-Designated Router
This example shows how to enable the configuration synchronization feature on the nondesignated
MSFC:
Router-151(config)# redundancy
Router-15(config-r)# high-availability
Router-15(config-r-ha)# config-sync
Router-15(config-r-ha)# end
Router-15#
00:03:31: %SYS-5-CONFIG_I: Configured from console by console
When you enable high-availability redundancy, the configuration mode is disabled on the console of the
Note
nondesignated MSFC; only EXEC mode is available.
