Chapter 1. Commands for MSTP 11

www.qtech.ru

1.1.17 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 port receives STP messages, it changes to work

in the STP mode again.

 This command can only be used when the switch is running in IEEE802.1s MSTP mode.

If the switch is running in IEEE802.1D STP mode, this command is invalid.

 Example: Force the port 1/0/2 to run in the MSTP mode.

 Switch(Config-If-Ethernet1/0/2)#spanning-tree mcheck

1.1.18 spanning-tree mode

 Command: spanning-tree mode {mstp | stp | rstp}

 no spanning-tree mode

 Function: Set the spanning-tree mode in the switch; the command “no spanning-tree

mode” restores the default setting.

 Parameter: mstp sets the switch in IEEE802.1s MSTP mode; stp sets the switch in

IEEE802.1D STP mode; rstp sets the switch in IEEE802.1D RSTP mode.

 Command mode: Global Mode

 Default: The switch is in the MSTP mode by default.

 Usage Guide: When the switch is in IEEE802.1D STP mode, it only sends standard

IEEE802.1D BPDU and TCN BPDU. It drops any MSTP BPDUs.

 Example: Set the switch in the STP mode.

 Switch(config)#spanning-tree mode stp

1.1.19 spanning-tree mst configuration

 Command: spanning-tree mst configuration

 no spanning-tree mst configuration

 Function: Enter the MSTP mode. Under the MSTP mode, the MSTP attributes can be

set. The command “no spanning-tree mst configuration” restores the attributes of the

MSTP to their default values.

 Command mode: Global Mode

 Default: The default values of the attributes of the MSTP region are listed as below:
