spanning-tree mst max-hops Configures the maximum hop count for a BPDU to travel before it is discarded. Syntax Parameters Default Command Mode Usage Information Example spanning-tree mst max-hops number number - Enter a maximum hop value (6 to 40). 20 CONFIGURATION 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. OS10(config)# spanning-tree mst max-hops 30 Supported Releases 10.2.0E or later spanning-tree port Sets the port type as the EdgePort. Syntax spanning-tree port type edge Parameters None Default Not configured Command Mode INTERFACE Usage Information When you configure an EdgePort on a device running STP, the port immediately transitions to Forwarding state. Only configured ports connected to end hosts act as EdgePorts. Example OS10(config)# spanning-tree port type edge Supported Releases 10.2.0E or later show spanning-tree mst Displays MST configuration information.
