Enabling VTS L2 High Availability
To enable VTC L2 HA, VTC1 and VTC2 must be on the same subnet.
![]() Note |
Cisco VTS supports dual stack clusters for L2 HA. Have both the VTCs (vts01 and vts02) installed and configured with IPv6 & IPv4 address for dual stack to be supported. Both of the VTCs should be reachable by any means with IPv6 address or IPv4 address. |
![]() Note |
Before enabling HA, make sure that both VTC 1 and VTC 2 have the same password. If not, go to the VTC GUI and do a change password on newly brought up VTC, to make the password identical with that of the other VTC . When you upgrade a VTC / bring up a new VTC / do a hardware upgrade of VTC host, you should make sure that password is the same. |
Setting up the VTC Environment
You need to set up the VTC environment before you run the high availability script.
Procedure
Step 1 |
Create a copy of cluster.conf file from cluster.conf.tmpl, which is under the /opt/vts/etc directory. For example:
|
||
Step 2 |
Specify the VIP address and the details of the two nodes in cluster.conf file . For example:
|
Enabling VTC High Availability
You must run the cluster_install.sh script on both VTCs to enable high availability.
Procedure
Step 1 |
Run the cluster installer script /opt/vts/bin/cluster_install.sh on both VTC1 and VTC2 . For example:
|
Step 2 |
Check the status on both the nodes to verify whether both nodes online, and node which got installed first is the master, and the other, slave. For example:
