Manually Binding Ports

To manually bind ports, use the commands:
configure stpd stpd_name add vlan vlan_name ports [all | port_list] {[dot1d | emistp | pvst-plus]}

configure vlan vlan_name add ports [all | port_list] {tagged {tag} | untagged} stpd stpd_name {[dot1d | emistp | pvst-plus]}

The first command adds all ports or a list of ports within the specified VLAN (Virtual LAN) to an STPD (Spanning Tree Domain). For EMISTP and PVST+, the carrier VLAN must already exist on the same set of ports. The second command adds all ports or a list of ports to the specified VLAN and STPD at the same time. If the ports are added to the VLAN but not to the STPD, the ports remain in the VLAN.

For EMISTP and PVST+, if the specified VLAN is not the carrier VLAN and the specified ports are not bound to the carrier VLAN, the system displays an error message. If you configure MSTP (Multiple Spanning Tree Protocol) on your switch, MSTP does not need carrier VLANs.

Note
The carrier VLAN's ID must be identical to the ID of the STP (Spanning Tree Protocol) domain.

If you add a protected VLAN or port, that addition inherits the carrier VLAN‘s encapsulation mode, unless you specify the encapsulation mode when you execute the configure stpd add vlan or configure vlan add ports stpd commands. If you specify an encapsulation mode (dot1d, emistp, or pvst-plus), the STP port mode is changed to match; otherwise, the STP port inherits either the carrier VLANs encapsulation mode on that port or the STPD‘s default encapsulation mode.
For MSTP, you do not need carrier a VLAN. A CIST controls the connectivity of interconnecting MSTP regions and sends BPDUs across the regions to communicate region status. You must use the dot1d encapsulation mode in an MSTP environment. For more information about MSTP, see the section Multiple Spanning Tree Protocol.
To remove ports, use the command:
configure stpd stpd_name delete vlan vlan_name ports [all | port_list]

If you manually delete a protected VLAN or port, only that VLAN or port is removed. If you manually delete a carrier VLAN or port, all VLANs on that port (both carrier and protected) are deleted from that STPD.
