Chapter 4 Configuring High Availability (HA) Installing a Clean Access Server High Availability Pair Note service perfigo restart does not work when used to test high availability (failover). Instead, Cisco recommends "shutdown" or "reboot" on the machine to test failover, or, the CLI commands service perfigo stop and service perfigo start. See Useful CLI Commands for HA, page 4-43. Accessing High Availability Pair CAM Web Consoles Determining Active and Standby CAM Access the web console for each CAM in the HA pair by typing the IP address of each individual CAM (not the Service IP) in the URL/Address field of a web browser. You should have two browsers open. The web console for the Standby (inactive) CAM only displays a subset of the module menus and respective submenus available on the Active CAM. Note The CAM configured as HA-Primary may not be the currently Active CAM. Determining Primary and Secondary CAM In each CAM web console, go to Administration > CCA Manager > Failover. • The Primary CAM is the CAM you configured as the HA-Primary when you initially set up HA. • The Secondary CAM is the CAM you configured as the HA-Secondary when you initially set up HA. Note For releases prior to 4.0(0), the Secondary CAM is labeled as HA-Standby (CAM) for the initial HA configuration. Installing a Clean Access Server High Availability Pair This chapter describes how to set up two Clean Access Servers in high availability (HA) mode.By deploying Clean Access Servers in high-availability mode, you can ensure that important user authentication and connection tasks continue in the event of an unexpected shutdown.

Configuring High Availability (HA)
Installing a Clean Access Server High Availability Pair
Note
service perfigo restart
does not work when used to test high availability (failover). Instead, Cisco
recommends “shutdown” or “reboot” on the machine to test failover, or, the CLI commands
service
perfigo stop
and
service perfigo start
. See
Useful CLI Commands for HA, page 4-43

Accessing High Availability Pair CAM Web Consoles
Determining Active and Standby CAM
Access the web console for each CAM in the HA pair by typing the IP address of each individual CAM
(not the Service IP) in the URL/Address field of a web browser. You should have two browsers open.
The web console for the Standby (inactive) CAM only displays a subset of the module menus and
respective submenus available on the Active CAM.
Note
The CAM configured as HA-Primary may not be the currently Active CAM.
Determining Primary and Secondary CAM
In each CAM web console, go to
Administration > CCA Manager > Failover
.
•
The Primary CAM is the CAM you configured as the
HA-Primary
when you initially set up HA.
•
The Secondary CAM is the CAM you configured as the
HA-Secondary
when you initially set up
HA.
Note
For releases prior to 4.0(0), the Secondary CAM is labeled as
HA-Standby
(CAM) for the initial HA
configuration.
Installing a Clean Access Server High Availability Pair
