Force10 Resilient Ring Protocol (FRRP)
FRRP is a proprietary protocol for that offers fast convergence in a Layer 2 network without having to run the spanning tree
protocol (STP). The resilient ring protocol is an efficient protocol that transmits a high-speed token across a ring to verify the
link status. All the intelligence is contained in the master node with practically no intelligence required of the transit mode.
Important Points to Remember
● FRRP is media- and speed-independent.
● FRRP is a Dell Networking proprietary protocol that does not interoperate with any other vendor.
● Spanning Tree must be disabled on both primary and secondary interfaces before Resilient Ring protocol is enabled.
● A virtual local area network (VLAN) configured as the control VLAN for a ring cannot be configured as a control or member
VLAN for any other ring.
● Member VLANs across multiple rings are not supported in Master nodes.
● If multiple rings share one or more member VLANs, they cannot share any links between them.
● Each ring can have only one Master node; all others are Transit nodes.

Version Description
9.9(0.0) Introduced on the FN MXL.
9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage
Information
Executing this command without the optional ring-id command clears the statistics counters on all
the available rings. The system requires a command line confirmation before the command executes. This
command clears the following counters:
● hello Rx and Tx counters
