Verifying Line Card and SPIO Port Redundancy
View the configuration of the card by entering the following command:
show configuration card slot#
slot# is the chassis slot number where the line card or SPIO you want to configure is installed.
The following is a sample of output for an line card in slot 17 and a SPIO in slot 24 that both have redundancy enabled.
[local]host_name# show config card 17
config
card 17
redundancy port-mode
#exit
end
[local]host_name# show config card 24
config
card 24
redundancy port-mode
#exit
end
config
card 17
redundancy port-mode
#exit
end
[local]host_name# show config card 24
config
card 24
redundancy port-mode
#exit
end
Configuring Line Card and SPIO Port Redundancy Auto-Recovery
When port redundancy is enabled at the card level, you can configure a port auto-recovery feature. When a port failure
occurs and the preferred port is returned to service (link is up), control is automatically returned to that port. By default,
ports are in a non-revertive state, meaning that no ports are preferred, requiring a manual port switch to return use to the
original port.

ports are in a non-revertive state, meaning that no ports are preferred, requiring a manual port switch to return use to the
original port.
Important:
This feature is applied on a per port basis, allowing you to configure specific ports to be used on
individual line cards or SPIOs. For example, you could configure ports 1 through 4 as preferred on the line card in slot
17, and configure ports 5 through 8 as the preferred ports on the line card in slot 33. On a SPIO, you could configure
port 1 as preferred on the SPIO in slot 24 and configure port 2 as preferred on the SPIO in slot 25. In this scenario, both
line cards or SPIOs would be in an active state while providing line card and port redundancy for the other.

Use the following example to configure a preferred port for revertive, automatic return to service when a problem has
cleared:
cleared:

port ethernet slot#/port#

Notes:
If you do not specify a preference, redundancy is non-revertive. If you do specify a preference, redundancy is
revertive to the specified card.
