Chapter 15 Using Failover
Understanding Failover
The path that the traffic takes after failover depends on which device fails as follows:
• FWSM failure only—If the primary FWSM fails, then the secondary FWSM becomes active.
However, if the primary switch is still active, all VLAN traffic destined for the FWSM continues to
enter the primary switch. The secondary (now active) FWSM receives and sends all traffic over the
trunk (Figure 15-3).
