3Com MSR 50, MSR 30 manual Stp port priority, 619

619

instance instance-id: Enables output of port state transition information for the specified instance. The minimum value of instance-idis 0, representing the CIST, and the maximum value of this argument depends on the specific device model.

Description Use the stp port-logcommand to enable output of port state transition information for the specified instance or all instances.

Use the undo stp port-logcommand to disable output of port state transition information for the specified instance or all instances.

Whether this function is enabled by default depends on the specific device model.

Examples # Enable output of port state transition information for instance 2.

<Sysname> system-view

[Sysname] stp port-log instance 2

%Aug 16 00:49:41:856 2006 Sysname MSTP/3/PDISC: Instance 2’s Etherne t1/1 has been set to discarding state!

%Aug 16 00:49:41:856 2006 Sysname MSTP/3/PFWD: Instance 2’s Ethernet 1/2 has been set to forwarding state!

//The information mentioned above shows that in instance 2, that state of both Ethernet 1/1 and Ethernet 1/2 has changed to forwarding.

stp port priority

Syntax stp [ instance instance-id] port priority priority

undo stp [ instance instance-id] port priority

View Ethernet interface view, port group view

Parameters instance instance-id: Sets the priority of the current port(s) in a particular spanning tree instance. The minimum value of instance-idis 0, representing the CIST, and the maximum value of instance-idis 15.

priority: Port priority, in the range of 0 to 240 at the step of 16 (0, 16, 32..., for example).

Description Use the stp port priority command to set the priority of the port(s).

Use the undo stp port priority command to restore the default.

By default, the port priority is 128.

Note that:

■Configured in Ethernet interface view, the setting is effective on the current port only; configured in port group view, the setting is effective on all the ports in the port group.
