The spanning-tree max-age Global Configuration mode command configures the Spanning Tree bridge
maximum age. Use the no form of this command to return to the default configuration.
Syntax
• spanning-tree max-age seconds
• no spanning-tree max-age
• seconds — Time in seconds. (Range: 6 - 40)
Default Configuration
The default maximum age for IEEE Spanning Tree Protocol (STP) is 20 seconds.
Command Mode
Global Configuration mode.
User Guidelines
When configuring the maximum age, the following relationships should be kept:
– 2*(Forward-Time - 1) >= Max-Age
– Max-Age >= 2*(Hello-Time + 1)
Example
The following example configures the Spanning Tree bridge maximum-age to 10 seconds.
spanning-tree priority
The spanning-tree priority Global Configuration mode command configures the Spanning Tree priority
of the device. The priority value is used to determine which bridge is elected as the root bridge. Use the
no form of this command to return to the default configuration.
Syntax
• spanning-tree priority priority
• no spanning-tree priority
• priority — Priority of the bridge. (Range: 0 - 61440 in steps of 4096)
