CLI Reference Guide

983

spanning-tree mst (forward-time | max-age | max-hops)

Use this command to configure the Protocol Timers used by the STP module in

MSTP mode.

spanning-tree mst {forward-time SECONDS | max-age SECONDS | max-hops HOP-COUNT}

Default forward-time:15 seconds.

max-age: 20 seconds.

max-hops: 20 hops.

Command Mode Global configuration.

Usage Guideline There are some constraints on the relationship of the three timers. Please refer

to the following formulas:

2 × (Bridge_Forward_Delay - 1.0 seconds) >= Bridge_Max_Age

Bridge_Max_Age >= 2 × (Bridge_Hello_Time + 1.0 seconds)

Example This example shows how to configure bridge timers for MSTP version.

Syntax Description

forward-time

SECONDS

The maximum delay time in seconds for one BPDU to be transmitted by a bridge

and received from another bridge. The range is 4 to 30 seconds.

max-age SECONDS Used to determine if a BPDU is valid. The range is 6 to 40 seconds.

max-hops

HOP-COUNT

Used to restrict the forwarded times of one BPDU. The range is 6 to 40 hops.

Switch# configure terminal

Switch(config)#spanning-tree mst max-age 19

Switch(config)#spanning-tree mst max-hops 19
