spanning-tree mst max-hops
Configures the maximum hop count for a BPDU to travel before it is discarded.
Syntax
spanning-tree mst max-hops number
Parameters number — Enter a maximum hop value, from 6 to 40.
Default 20
Command Mode CONFIGURATION
Usage
Information
A device receiving BPDUs waits until the max-hops value expires before discarding it. When a device
receives the BPDUs, it decrements the received value of the remaining hops and uses the resulting value
as remaining-hops in the BPDUs. If the remaining MSTP 1333 hops reach zero, the device discards the
BPDU and ages out any information that it holds for the port. The command configuration applies to all
common IST (CIST) in the MST region.
Example
OS10(config)# spanning-tree mst max-hops 30
