-TREE MAX-HOPS (MSTP)
spanning-tree max-hops (MSTP)
Overview Use this command to specify the maximum allowed hops for a BPDU in an MST
region. This parameter is used by all the instances of the MST region.
Use the no variant of this command to restore the default.
Use this command for MSTP only.
Syntax
spanning-tree max-hops <hop-count>
no spanning-tree max-hops <hop-count>
Default The default max-hops in a MST region is 20.
Mode Global Configuration
Usage Specifying the max hops for a BPDU prevents the messages from looping
indefinitely in the network. The hop count is decremented by each receiving port.
When a device receives an MST BPDU that has a hop count of zero, it discards the
BPDU.
Examples
awplus# configure terminal
awplus(config)# spanning-tree max-hops 25
awplus# configure terminal
awplus(config)# no spanning-tree max-hops
Parameter Description
<hop-count> Specify the maximum hops the BPDU will be valid for in the range
