Force10 Resilient Ring Protocol (FRRP) | 375
Troubleshooting FRRP
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.
• FRRP can be configured on Layer 2 interfaces only
• Spanning Tree (if enabled globally) must be disabled on both Primary and Secondary when FRRP is
enabled.
• When the interface ceases to be a part of any FRRP process, if Spanning Tree is enabled globally,
it must be enabled explicitly for the interface.
• The maximum number of rings allowed on a chassis is 255.
Sample Configuration and Topology
Figure 17-3 is an example of a basic FRRP topology. Below the figure are the associated CLI commands.
