Ring ID: the range is from 1 to 255.Troubleshooting FRRPTo 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 forthe interface.• The maximum number of rings allowed on a chassis is 255.Sample Configuration and TopologyThe following example shows a basic FRRP topology.Example of R1 MASTERinterface TenGigabitEthernet 1/24no ip addressswitchportno shutdown!interface TenGigabitEthernet 1/34no ip addressswitchportno shutdown!interface Vlan 101no ip addresstagged TenGigabitEthernet 1/24,34no shutdown!interface Vlan 201no ip addresstagged TenGigabitEthernet 1/24,34no shutdown!protocol frrp 101interface primary TenGigabitEthernet 1/24secondary TenGigabitEthernet 1/34 control-vlan 101member-vlan 201mode masterno disableExample of R2 TRANSITinterface TenGigabitEthernet 2/14no ip addressswitchportno shutdown!interface TenGigabitEthernet 2/31no ip addressswitchportno shutdown!interface Vlan 101Force10 Resilient Ring Protocol (FRRP) 253
