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 to an STPD. 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 on your switch, MSTP does not need
carrier VLANs.
Note
The carrier VLAN's ID must be identical to the ID
of the STP 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.

Member VLANs. For more detailed information about these
command line interface (CLI) commands, see the
ExtremeXOS Command
Reference Guide.
