Useful CLI Commands for HA Chapter 4 Configuring High Availability (HA) My node is active, peer node is standby [root@rjcas_1 bin]# This CAS is the active CAS in the HA-pair. 2. Run the fostate.sh script on the second CAS: [root@rjcas_2 bin]# ./fostate.sh My node is standby, peer node is active [root@rjcas_2 bin]# This CAS is the standby CAS in the HA-pair. Accessing High Availability Pair CAS Web Consoles Determining Active and Standby CAS From the CAM web console, go to Device Management > CCA Servers > List of Servers to view your HA-CAS pairs. The List of Servers page displays the Service IP of the CAS pair first, followed by the IP address of the Active CAS in brackets. When a secondary CAS takes over, its IP address will be listed in the brackets as the Active server. Note The CAS configured in HA-Primary Mode may not be the currently Active CAS. Determining Primary and Secondary CAS Open the direct access console for each CAS in the pair by typing the following in the URL/Address field of a web browser (you should have two browsers open): • For the Primary CAS, type: https:///admin. For example, https://172.16.1.2/admin. • For the Secondary CAS, type: https:///admin. For example, https://172.16.1.3/admin. In each CAS web console, go to Administration > Network Settings > Failover > General. • The Primary CAS is the CAS you configured in HA-Primary Mode when you initially set up HA. • The Secondary CAS is the CAS you configured in HA-Secondary Mode when you initially set up HA. For releases prior to 4.0(0), the Secondary CAS is labelled as HA-Standby Mode (CAS) for the initial HA configuration. 4-46 Cisco NAC Appliance Hardware Installation Guide OL-20326-01

Chapter 4
Configuring High Availability (HA)
Useful CLI Commands for HA
My node is active, peer node is standby
[root@rjcas_1 bin]#
This CAS is the active CAS in the HA-pair.
2.
Run the fostate.sh script on the second CAS:
[root@rjcas_2 bin]#
./fostate.sh
My node is standby, peer node is active
[root@rjcas_2 bin]#
This CAS is the standby CAS in the HA-pair.
Accessing High Availability Pair CAS Web Consoles
Determining Active and Standby CAS
From the CAM web console, go to
Device Management > CCA Servers > List of Servers
to view your
HA-CAS pairs. The List of Servers page displays the
Service IP
of the CAS pair first, followed by the
IP address of the Active CAS in brackets. When a secondary CAS takes over, its IP address will be listed
in the brackets as the Active server.
Note
The CAS configured in HA-Primary Mode may not be the currently Active CAS.
Determining Primary and Secondary CAS
Open the direct access console for each CAS in the pair by typing the following in the URL/Address
field of a web browser (you should have two browsers open):
•
For the Primary CAS, type:
https://
<primary_CAS_eth0_IP_address>
/admin
. For example,
.
•
For the Secondary CAS, type:
https://
<secondary_CAS_eth0_IP_address>
/admin
. For example,
.
In each CAS web console, go to
Administration > Network Settings > Failover > General
.
•
The Primary CAS is the CAS you configured in
HA-Primary Mode
when you initially set up HA
.
•
The Secondary CAS is the CAS you configured in
HA-Secondary Mode
when you initially set up
HA.
For releases prior to 4.0(0), the Secondary CAS is labelled as
HA-Standby Mode
(CAS) for the initial
HA configuration.
