Sample Configurations
Example 6: Routed Mode Failover
The following configuration shows a multiple context mode FWSM with each context in routed mode in
one switch, and another FWSM in a second switch acting as a backup (see
B, and C) monitors the inside interface, and context A, which is the admin context, also monitors the
outside interface. Because the outside interface is shared among all contexts, monitoring in one context
benefits all contexts.
The primary FWSM is configured with the failover preempt command, which causes it to become the
active unit upon boot, even if the secondary unit is in the active state. The secondary FWSM is also in
multiple context mode, and has the same software release.
