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.
Sample Configuration and Topology
The following example shows a basic FRRP topology.
