High Availability Using Line Card Redundancy
Command
show redundancy linecard all
show redundancy linecard subslot
show redundancy linecard group
show redundancy linecard history
show redundancy linecard sub-block
The output examples in this section use the following configuration:
!
redundancy
linecard-group 0 y-cable
member subslot 8/1 primary
member subslot 8/0 secondary
mode sso
!
controller T3-RED 8/1/0
controller T3-RED 8/1/1
controller T3-RED 8/1/2
controller T3-RED 8/1/3

state of all line card slots. The line card group is indicated as "None" if the slot is empty, or if it contains
a line card that has not been configured for redundancy.
For a redundant line card, the mode can be primary or secondary and is established when redundancy is
configured. The mode of a line card does not change. For the 4-Port Channelized T3 Half-Height line
card, the line card in subslot 0 is always secondary, and the line card in subslot 1 is always primary.
The line card role indicates which line card in a redundant configuration is sending and receiving traffic.
The line card with the active role is sending and receiving traffic. The other line card in a redundant
configuration has the role of standby. Unlike the line card mode, the role of a line card can change.
In Example 4-2
subslot 0 has the active role, even though its mode is secondary.
