bridge <group#> max-age <seconds>
Use the bridge max-age command to specify the interval (in seconds) the bridge will wait to receive
Bridge Protocol Data Units (BPDUs) from the root bridge before assuming the network has changed, thus
re-evaluating the spanning-tree topology. Use the no form of this command to return to the default interval.
Syntax Description
<group#>
Bridge group number (1 to 255) specified using the
bridge
command
<seconds>
Wait interval (in seconds) between received BPDUs (from the root bridge)
(valid range: 6 to 200)
Default Values
<seconds>
20 seconds
Command Modes
(config)# Global Configuration Mode

Functional Notes
A bridged network can provide excellent traffic management to reduce collisions and limit the amount of
bandwidth wasted with unnecessary transmissions. Configuring an appropriate max-age interval helps reduce
the number of Bridge Protocol Data Units (BPDUs) transmitted on the network.
Usage Examples
The following example configures a max-age interval of 45 seconds for bridge-group 17:
(config)#
bridge 17 max-age 45
