Dell Force10 MXL Blade MXL 10/40GbE Switch IO Module FTOS Command Line Referen - Page 375

Parameters max-age Enter a number of seconds the FTOS waits before refreshing configuration information. Range: 6 to 40 Default: 20 seconds. Defaults 20 seconds Command Modes MULTIPLE SPANNING TREE Command History Version 8.3.16.1 Introduced on MXL 10/40GbE Switch IO Module Related Commands edge-port bpdufilter default hello-time The amount of time the interface waits in the Blocking State and the Learning State before transitioning to the Forwarding State. Changes the time interval between BPDUs. max-hops Configure the maximum hop count. Syntax max-hops number To return to the default values, use the no max-hops command. 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 Usage Information Version 8.3.16.1 Introduced on MXL 10/40GbE Switch IO Module 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 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, use the no msti instance {vlan range | bridge-priority priority} command.
