Chapter 45 MRSTP Commands

45.3 Command Examples
This example configures MRSTP in the following way:
• Enables MRSTP on the Switch.
• Activates tree 1 and sets the bridge priority, Hello Time, Maximum Age and Forward
Values for this RSTP configuration.
• Activates MRSTP for ports 1-5 and sets path cost on these ports to 127.
• Adds ports 1-5 to tree index 1.
In this example, we enable MRSTP on ports 21-24. Port 24 is connected to the host while ports
21-23 are connected to another switch.
mrstp interface <port-list> edge-port Sets the specified ports as edge ports. This allows
the port to transition to a forwarding state
immediately without having to go through the
listening and learning states.
Note: An edge port becomes a non-edge
port as soon as it receiveds a Bridge
Protocol Data Units (BPDU).
C13
no mrstp interface <port-list> edge-
port
Sets the listed ports as non-edge ports. C 13
mrstp interface <port-list> path-cost
<1-65535>
Sets a path cost to the specified ports. C 13
mrstp interface <port-list> priority
<0-255>
Sets the priority value to the specified ports for
MRSTP.
C13
mrstp interface <port-list> tree-index
<tree-index>
Assigns the specified port list to a specific MRSTP
configuration.
C13
no mrstp <tree-index> Disables the specified MRSTP configuration. C 13
no mrstp interface <port-list> Disables the MRSTP assignment from the specified
port(s).
