Spanning-Tree Operation

802.1s Multiple Spanning Tree Protocol (MSTP)

[ mcheck ]

Forces a port to send RSTP BPDUs for 3 seconds. This

allows for another switch connected to the port and

running RSTP to establish its connection quickly and for

identifying switches running 802.1D STP. If the whole-

switch force-version parameter is set to stp-compatible,

the switch ignores the mcheck setting and sends 802.1D

STP BPDUs out all ports. Disable this feature on all ports

that are known to be connected to devices that are running

802.1D STP. (Default: Yes - enabled)

The no spanning-tree < port-list > mcheck ] command disables

mcheck.

Syntax: spanning-tree < port-list > < hello-time | path-cost | point-to-point-mac |

priority >

[ hello-time < global | 1 - 10 >

When the switch is the CIST root, this parameter specifies

the interval (in seconds) between periodic BPDU

transmissions by the designated ports. This interval also

applies to all ports in all switches downstream from each

port in the < port-list >. A setting of global indicates that the

ports in < port-list > on the CIST root are using the value set

by the global spanning-tree hello-time value (page 62).

When a given switch “X” is not the CIST root, the per-port

hello-time for all active ports on switch “X” is propagated

from the CIST root, and is the same as the hello-time in use

on the CIST root port in the currently active path from

switch “X” to the CIST root. (That is, when switch “X” is

not the CIST root, then the upstream CIST root’s port hello-

time setting overrides the hello-time setting configured on

switch “X”. (Default Per-Port setting: Use Global. Default

Global Hello-Time: 2.)
