Enabling Line Card and SPIO Port Redundancy

the port on the secondary switch that the line card in slot 33 is connected to, allowing it to redirect and transport
data.
Figure 8: Port Redundancy Failover in External Network Device Failure Scenario
In the example above, a switch failure causes a link down state on all ports connected to that switch. This
failure causes all redundant ports on the line card in slot 33 to move into the active state and utilize the
redundant switch.
Enabling Line Card and SPIO Port Redundancy
Use the following example to enable port redundancy:
configure
card slot#
Notes:
• The card-mode keyword indicates that no port redundancy is used. The system provides card-level

redundancy, which is triggered by an internal failure. The port-mode keyword, available for Ethernet
and SPIO line cards, indicates that port redundancy will be enabled. This is the default redundancy mode.
You do not need to use this configuration for each line card or SPIO. The system intuitively understands
that if the command is entered for an active line card, the standby line will operate in the same mode. For
example, if you enter the command for the line card in slot 17, it automatically places the line card in Slot
33 into port redundant operation.
If you network-boot a dual-SMC chassis with SPIO port redundancy enabled, you should have CFE1.1.0
or greater in flash on both SMCs. Otherwise, you risk having a standby SMC that can't boot from the
network in certain circumstances. You can use any version of the CFE with SPIO port redundancy if the
SMCs boot from a local file system (/flash, /pcmcia1, or /pcmcia2).
