Figure 10. 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.
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:
Notes:
The
keyword indicates that no port redundancy is used. The system provides card-level
redundancy, which is triggered by an internal failure. The
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).

Save the configuration as described in the Verifying and Saving Your Configuration chapter.
