Switch(config)#spanning-tree mst cisco-interoperability enable

Close and CISCO compatible：

Switch#configure terminal

Switch(config)#spanning-tree mst cisco-interoperability disable

Reset protocol checking task

In order to be compatible with the 802.1D STP protocol, the system can automatically detect

the protocol of the other system running. Determine the protocol for the port running according to

the protocol running by the other party。

In some cases reset protocols are required. For example, the system negotiated a port to run

the STP protocol, and after a period of time, the other side of the device running STP protocol has

been replaced by a host. When I need to configure the port for fast port, but the port has been

running the STP protocol, and the protocol negotiation task has stopped; then need to reset this

protocol negotiation task let it re negotiation between it and the host protocol。

Reset the protocol reconnaissance task of the whole device：

Switch#clear spanning-tree detected protocols

The protocol reconnaissance task of resetting a port：

Switch#clear spanning-tree detected protocols interface <if-name>

8.2.3 Domain configuration

Two or more devices in the same domain, they must have the same VLAN instance mapping

relationship, the same modified version number and the same domain name。

One domain has one or more members with the same MST configuration, and each member

can handle the RSTP BPDUS capability. There are no restrictions on the number of members in a

network, but each domain can support up to 16 instances。

The configuration of the instance is explained in the instance configuration, which only

introduces the domain name configuration and the revision version number configuration。

Configuring domain names：

Switch#configure terminal

Switch(config)#spanning-tree mst configuration

Switch(config-mst)#region <region-name>
