Example OS10(config)# spanning-tree mst max-age 10 Supported Releases 10.2.0E or later 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 remaininghops 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 Supported Releases 10.2.0E or later show spanning-tree mst Displays MST configuration information. Syntax show spanning-tree mst configuration Parameters None Default Not configured Command Mode EXEC Usage Information Enable MSTl before using this command.
