spanning-tree (timers)

Use this command to set the value of Spanning-Tree Timers. It is only used for

RSTP and STP version.

spanning-tree [hello-time SECONDS | forward-time SECONDS | max-age SECONDS]

Default hello-time:2.

forward-time: 15.

max-age: 20.

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)

An error message will be returned if the equation is not satisfied.

This configuration will take effect on STP version and RSTP version only. In

MSTP mode, Use the command spanning-tree mst (timers) to configure the

MSTP timers.

Example This example shows how to configure the STP timers.

Verify the settings by entering the show spanning-tree command.
