Rapid Spanning Tree Protocol (RSTP)

MN700004 Rev 01

125

Argument Description

UU/SS/PP

Unit, slot and port number of an interface (i.e. – 1/1/8).

The (config-if

UU/SS/PP

)# prompt-line indicates interface

UU/SS/PP

Configuration mode.

Table 13-2 summarizes the RSTP commands available in Protocol Configuration mode.

Table 13-3 summarizes the RSTP commands available in interface configuration mode.

Table 13-4 summarizes the RSTP debug commands.

Table 13-2 RSTP Commands in Protocol Configuration Mode

C o m m a n d D e s c r i p t i o n

rapid-spanning-tree

Displays the current RSTP parameter settings.

rapid-spanning-tree
enable/disable

Enables/disables the RSTP option.

rapid-spanning-tree priority

Sets the RSTP bridge priority

rapid-spanning-tree hello-time

Sets time interval between BPDU transmissions from the
ports of this unit, in hundredths of seconds.

rapid-spanning-tree forward-delay

Sets the time duration in Listening and Learning states that
precede the Forwarding state, in hundredths of seconds. Also
used to age dynamic entries in the Forwarding database
when a topology change is under way.

rapid-spanning-tree max-age

Sets the time, in seconds, that learned RSTP information is
kept before being discarded.

rapid-spanning-tree interface

Changes to specified interface configuration mode and
displays the RSTP settings for that interface.

NOTE

A BPDU (Bridge Protocol Data Unit) transmission is an RSTP information-exchange packet
sent out at periodic intervals to other units in the network, to detect loops in the network
topology.

Table 13-3 RSTP Commands in Interface Configuration Mode

Command

Description

rapid-spanning-tree all

Displays all RSTP ports table

rapid-spanning-tree edge-port

Determines if the configured interface is an edge port.

rapid-spanning-tree link-type

Sets the RSTP port link type.

rapid-spanning-tree path-cost

Sets RSTP port path-cost

rapid-spanning-tree priority

Sets RSTP port priority
