The ring ID
The state of MRP. The state can be one of the following:
•
•
Whether this node is the master for the ring. The role can be one of the
following:
•
•
The ID of the master VLAN in the topology group used by this ring. If a
topology group is used by MRP, the master VLAN controls the MRP
settings for all VLANs in the topology group.
NOTE: The topology group ID is 0 if the MRP VLAN is not the master
The topology group ID.
The interval, in milliseconds, at which the Forwarding port on the ring
master node sends Ring Hello Packets (RHPs).
The number of milliseconds an MRP interface that has entered the
Preforwarding state will wait before changing to the Forwarding state.
If a member port in the Preforwarding state does not receive an RHP
within the Preforwarding time (Prefwing time), the port assumes that a
topology change has occurred and changes to the Forwarding state.
The secondary port on the Master node changes to Blocking if it receives
an RHP, but changes to Forwarding if the port does not receive an RHP
before the preforwarding time expires.
NOTE: A member node Preforwarding interface also changes from

•
Master node – The interface generates RHPs.
•
Member node – The interface forwards RHPs received on the
other interface (the secondary interface).
secondary – The interface does not generate RHPs.
•
Master node – The interface listens for RHPs.
•
Member node – The interface receives RHPs.
blocking – The interface is blocking Layer 2 data traffic and RHPs
disabled – The interface is down
forwarding – The interface is forwarding Layer 2 data traffic and
RHPs
preforwarding – The interface is listening for RHPs but is blocking
