14.1.16 spanning-tree max-hop
Command:
spanning-tree max-hop <hop-count>
no spanning-tree max-hop
Function:
Set maximum hops of BPDU in the MSTP region; the command “no spanning-tree max-hop”
restores the default setting.
Parameter:
<hop-count> sets maximum hops. The valid range is from 1 to 40.
Command mode:
Global Mode
Default:
The max hop is 20 by default.
Usage Guide:
The MSTP uses max-age to count BPDU lifetime. In addition, MSTP also uses max-hop to count
BPDU lifetime. The max-hop is degressive in the network. The BPDU has the max value when it
initiates from MSTI root bridge. Once the BPDU is received, the value of the max-hop is reduced by
1. When a port receives the BPDU with max-hop as 0, it drops this BPDU and sets itself as
designated port to send the BPDU.
Example:
Set max hop to 32.
Switch(config)#spanning-tree max-hop 32
14.1.17 spanning-tree mcheck
Command:
spanning-tree mcheck
Function:
Force the port to run in the MSTP mode.
Command mode:
Port Mode
Default:
The port is in the MSTP mode by default.
Usage Guide:
If a network which is attached to the current port is running IEEE 802.1D STP, the port converts itself
to run in STP mode. The command is used to force the port to run in the MSTP mode. But once the
