Description This command adds a VLAN to the specified STP. If as a result of the VLAN
addition, ports are moved from one STP to another STP, the two affected STPs
are initialised if they are currently enabled. Any previously disabled ports in
the STPs are enabled.
The default VLAN cannot be added to an STP. The default VLAN always
belongs to the default STP. A VLAN cannot be explicitly added to the default
STP. A VLAN is implicitly added to the default STP when it is deleted from any
other STP. Only a VLAN belonging to the default STP can be added to another
STP. If the VLAN already belongs to another STP, it must first be deleted from
its current STP (and so be returned to the default STP), and then added to the
new STP.
Within any given STP, all VLANs belonging to it use the same Spanning Tree.
A port can belong to only one STP, except on the Rapier i Series switches. If a
port is a member of multiple VLANs, then all these VLANs must belong to the
same STP.
On the Rapier i Series switches only, a port can belong to more than one STP if
the port is a member of two or more VLANs that belong to different STPs.
The vlan parameter specifies the name or the numerical VLAN Identifier of the
VLAN to be added to the STP. The name is not case sensitive, although the case
is preserved for display purposes. The VLAN specified must exist.
When a VLAN is added to an STP, the ports in the VLAN have default STP
parameter values. The ports do not retain non-default STP configurations
made when the VLAN was associated with any other STP.
Examples To add th e research VLAN to the company STP, use the command:
add stp=company vlan=research
