Parameters range Enter a number for the maximum hop count. Range: 1 to 40 Default: 20 Defaults 20 hops Command Modes MULTIPLE SPANNING TREE Command History Version 7.6.1.0 Version 7.5.1.0 Version 6.5.1.0 Added support for S-Series Added support for C-Series Introduced Usage Information The max-hops is a configuration command that applies to both the IST and all MST instances in the MSTP region. The BPDUs sent out by the root switch set the remaining-hops parameter to the configured value of max-hops. When a switch receives the BPDU, it decrements the received value of the remaining hops and uses the resulting value as remaining-hops in the BPDUs. If the remaining-hops reaches zero, the switch discards the BPDU and ages out any information that it holds for the port. msti c e s Configure Multiple Spanning Tree instance, bridge priority, and one or multiple VLANs mapped to the MST instance. Syntax msti instance {vlan range | bridge-priority priority} To disable mapping or bridge priority no msti instance {vlan range | bridge-priority priority} Parameters msti instance vlan range bridge-priority priority Enter the Multiple Spanning Tree Protocol Instance Range: zero (0) to 63 Enter the keyword vlan followed by the identifier range value.
