MSTP mode by default.
NOTE:
Whether you need to specify the MSTI or VLAN for the spanning tree configuration varies with the
spanning tree modes.
• In STP-compatible or RSTP mode, do not specify any MSTI or VLAN. Otherwise, the spanning tree
configuration is ineffective.
• In MSTP mode, if you specify an MSTI, the spanning tree configuration is effective for the specified MSTI.
If you specify a VLAN list, the spanning tree configuration is ineffective. If you do not specify any MSTI
or VLAN, the spanning tree configuration is effective for the CIST.
• In PVST mode, if you specify a VLAN list, the spanning tree configuration is effective for the specified
VLANs. If you do not specify any VLAN, the spanning tree configuration is ineffective.
