Adding HA CAMs to Network
Figure 4-3
shows how HA-CASs can be added to the core-distribution-access network. In this example,
the CAS is configured as an L2 OOB Virtual Gateway in Central Deployment. The HA heartbeat
connection is configured over both a serial interface and a dedicated eth2 interface. Link-failure based
failover connection can also be configured over the eth0 and/or eth1 interfaces.
Note
Cisco NAC network modules installed in Cisco Integrated Services Routers (ISRs) do not support high
availability.
