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
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.
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.
Important
Use the following example to configure a preferred port for revertive, automatic return to service when a
problem has cleared:
configure
port ethernet slot#/port#
preferred slot slot#
end
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.
•
Repeat for each additional port that you want to make preferred.
