Configure VLAN mapping (for Central Deployment only). After you have added the CAS to the
CAM web console, make sure to set the VLAN to be mapped under Device Management > CCA
Servers > Manage [CAS_IP] > Advanced > VLAN Mapping. Also make sure you check the
“Enable VLAN Mapping” checkbox and click Update. See

For the 802.1q ports configuration on the switch, make sure to prune all other VLANs for switches
trunking to eth0 and eth1 of the CAS except those used for the CAS Management VLAN and the
User VLANs.

Access the CAS Over a Serial Connection
To install the Clean Access Server software from the CD-ROM or to perform its initial configuration,
you will need to access the server machine’s command line. This can be done in one of two ways:

Connect a serial cable from an external workstation (PC/laptop) to the server machine and open a
serial connection using terminal emulation software (such as HyperTerminal or SecureCRT) on the
external workstation.

This section describes how to access the server machine over a serial connection.
Note
The steps described here for accessing the server directly through a serial connection can be used later
for troubleshooting. If the server cannot be reached through the web admin console, you can serially
connect to the server to restore the server to a reachable state, usually by correcting its network settings.
