MRP CLI example

The following examples show the CLI commands required to implement the MRP configuration
shown in
NOTE
For simplicity, the figure shows the VLANs on only two switches. The CLI examples implement the
ring on all four switches.

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's Preforwarding interface also changes from
The device's two interfaces with the ring.

groups are listed.
primary - The primary interface
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 Layer
2 data traffic
