Configuring Standby Interfaces
Examples The following example configures three Fast Ethernet interfaces to be part of the same standby group,
with interface 3/0 as the active interface:
Console(config-if)# interface fastEthernet 3/0 standby 1 ip 172.16.10.10 255.255.254.0
Console(config-if)# interface fastEthernet 3/1 standby 1 ip 172.16.10.10 255.255.254.0
Console(config-if)# interface fastEthernet 3/2 standby 1 ip 172.16.10.10 255.255.254.0
Console(config-if)# interface fastEthernet 3/0 standby 1 priority 300
Console(config-if)# interface fastEthernet 3/1 standby 1 priority 200
Console(config-if)# interface fastEthernet 3/2 standby 1 priority 100
Console(config-if)# interface fastEthernet 3/0 standby 1 errors 10000
Console(config-if)# interface fastEthernet 3/1 standby 1 errors 10000
Console(config-if)# interface fastEthernet 3/2 standby 1 errors 10000
The following example displays information about the standby group configuration by entering the show
standby EXEC command. In the following sample command output, one standby group (Standby
Group 1) is configured on this Service Engine. The command output also shows which member interface
is the active interface. In this case, the active interface is the Fast Ethernet slot 3/port 0 interface.
ServiceEngine# show standby
Standby Group:1
IP address: 172.16.10.10, netmask: 255.255.254.0
Maximum errors allowed on the active interface: 10000
Member interfaces:
FastEthernet 3/0 priority: 300
FastEthernet 3/1 priority: 200
FastEthernet 3/2 priority: 100
Active interface: FastEthernet 3/0
Note To display information about a specific standby group configuration, enter the show interface standby
group_number EXEC command.
The following example creates a standby group, Standby Group 1:
ServiceEngine# configure
ServiceEngine(config)# interface standby 1
ServiceEngine(config-if)#
The following example assigns a group IP address of 10.10.10.10 and a netmask of 255.0.0.0 to Standby
Group 1.
ServiceEngine(config-if)# ip address 10.10.10.10 255.0.0.0
ServiceEngine(config-if)# errors 500
priority_level Each member interface is assigned a priority number. The member interface with the
highest priority number is the active interface for that standby group. Only the active
interface uses the group IP address.
If the priority option is specified without a priority number, the default value of 100
is used.
shutdown (Optional) Shuts down the specified standby group (Standby Group 1, 2, 3, or 4).
You can shut down a standby group even if you have not configured a group IP
address of the standby group.
Note When a standby group is shut down, all of the alarms previously raised by
this standby group are cleared.
