Metro Ring Protocol (MRP)
MRP CLI example
The following examples show the CLI commands required to implement the MRP configuration
shown in
Figure 17 on page 290.
NOTE
For simplicity, the figure shows the VLANs on only two switches. The CLI examples implement the
ring on all four switches.
Ring interfaces The device two interfaces with the ring.
NOTE: If the interfaces are trunk groups, only the primary ports of the
groups are listed.
Interface role The interface role can be one of the following:
•
primary
•
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.
Forwarding state Whether MRP Forwarding is enabled on the interface. The forwarding
state can be one of the following:
•
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
Active interface The physical interfaces that are sending and receiving RHPs.
NOTE: If a port is disabled, its state is shown as “disabled”.
NOTE: If an interface is a trunk group, only the primary port of the group
is listed.
Interface Type Shows if the interface is a regular port or a tunnel port.
RHPs sent The number of RHPs sent on the interface.
NOTE: This field applies only to the master node. On non-master nodes,
this field contains 0. This is because the RHPs are forwarded in
hardware on the non-master nodes.
RHPs rcvd The number of RHPs received on the interface.
NOTE: On most devices, this field applies only to the master node. On
non-master nodes, this field contains 0. This is because the
RHPs are forwarded in hardware on the non-master nodes.
TC RHPs rcvd The number of Topology Change RHPs received on the interface. A
Topology Change RHP indicates that the ring topology has changed.
State changes The number of MRP interface state changes that have occurred. The
state can be one of the states listed in the Forwarding state field.
Interface Type Shows if the interface is a regular port or a tunnel port.
