traffic you expect to be inspected by the FWSM. The FWSM has an internal 6-Gbps EtherChannel to the
switch, so if the FWSM runs at full capacity, the trunk between the two devices needs to include at least
six 1-Gbps interfaces. EtherChannel aggregates the bandwidth of up to eight compatibly configured
ports into a single logical link. (See the

ensures that the VLANs pass through only one switch, which also contains the active FWSM. The trunk
between the two switches carries all FWSM VLANs, including the failover and state links (VLANs 10
and 11).
The FWSM failover is independent of the switch failover operation; however, the FWSM works in any
