TABLE 64 CLI display of MRP ring information

This field... Displays...

Ring id The ring ID

State The state of MRP. The state can be one of the following:

• enabled – MRP is enabled

• disabled – MRP is disabled

Ring role Whether this node is the master for the ring. The role can be one of the

following:

• master

• member

Topo group The topology group ID if a topology group is configured. This field will show the

value ‘not conf’ if no topology group is in use.

Hello time The interval, in milliseconds, which the forwarding port on the ring’s master

node sends Ring Hello Packets (RHPs). Configured in increments of 100ms.

Prefwing time The number of milliseconds a MRP interface will wait to move an interface in

blocking state to preforwarding state if no RHP’s are received. It is also the

number of milliseconds that an 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.

Configured in increments of 100ms.

NOTE: A member node’s preforwarding interface also changes from

preforwarding to forwarding if it receives an RHP whose forwarding bit

is on.

Ring interfaces The device’s two interfaces with the ring.

NOTE: If the interfaces are trunk groups, only the primary ports of the groups

are listed.
