Introduced on the C-Series. Introduced. Usage Information The max-hops command 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 Configure multiple spanning tree instance, bridge priority, and one or multiple VLANs mapped to the MST instance. C-Series, E-Series, S-Series, Z-Series, S4810 Syntax Parameters msti instance {vlan range | bridge-priority priority} To disable mapping or bridge priority, use the no msti instance {vlan range | bridge-priority priority} command. msti instance vlan range Enter the MSTP iInstance.
