F
Failover lets you configure two FWSMs so that one will take over operation if the other one fails. The
failover, failover
FWSM supports two failover configurations, Active/Active failover and Active/Standby failover. Each
mode
failover configuration has its own method for determining and performing failover. With
Active/Active failover, both units can pass network traffic. This lets you configure load balancing on
your network. Active/Active failover is only available on units running in multiple context mode. With
Active/Standby failover, only one unit passes traffic while the other unit waits in a standby state.
Active/Standby failover is available on units running in either single or multiple context mode.

can encapsulate a wide variety of protocol packet types inside IP tunnels, creating a virtual

subnetworks in a single-protocol backbone environment, IP tunneling using GRE allows network
expansion across a single protocol backbone environment.
