Troubleshooting the TMS zl Module in Routing Mode
Each module must have a unique priority number. You can select a priority
setting from 1 to 255.
If the modules in the cluster are in different switches, you should also
ensure that the HA VLAN and all TMS VLANs are configured on both
switches.
Figure 10-26. Sample HA Configuration
■ The master is down, but a failover does not occur.
Check the following:
• Ensure that the ports that connect the host switches are tagged
members of the HA VLAN.
• If the cluster members are in two different switches, ensure that the
same TMS VLANs are configured on both host switches.
• Determine if a device between the two switch chassis failed. To
eliminate this source of failure, do not place devices between two
switch chassis that contain the cluster members.
