Troubleshooting FRRP
To troubleshoot FRRP, use the following information.
Configuration Checks
•
Each Control Ring must use a unique VLAN ID.
•
Only two interfaces on a switch can be Members of the same control VLAN.
•
There can be only one Master node for any FRRP group.
•
You can configure FRRP on Layer 2 interfaces only.
•
Spanning Tree (if you enable it globally) must be disabled on both Primary and Secondary interfaces when you enable FRRP.
•
When the interface ceases to be a part of any FRRP process, if you enable Spanning Tree globally, also enable it explicitly for the
interface.
•
The maximum number of rings allowed on a chassis is 255.
