ExtremeWare 7.7 Command Reference Guide 1583
configure stpd add vlan
configure stpd <spanning tree name> add vlan <vlan name> {ports <portlist>
[dot1d | emistp | pvst-plus]}
Description
Adds one or more VLANs, or a list of ports within a VLAN, to a specified STPD.
Syntax Description
Default
For ExtremeWare 6.1 (or earlier), the default is N/A.
For ExtremeWare 6.2 (or later), all ports are in
emistp
mode, except those in STPD s0, whose default
setting is
dot1d
mode.
Usage Guidelines
For version 6.2 or later, this command adds a list of ports within a VLAN to a specified STPD. If no
ports are specified, the entire VLAN is added.
For versions up to 6.1, this command adds one or more VLANs to the STPD. All VLANs participating
in the STPD elect a Root Bridge and create a loop-free, least-cost path to the bridge.
You must be careful to ensure that ports in overlapping domains do not interfere with the orderly
working of each domain’s protocol.
You must create a VLAN to add a VLAN to the STPD. To create a VLAN, use the create vlan command.
You can create STP domains using the create stpd command.
Use the keywords
dot1d
,
emistp
, and
pvst-plus
to specify STP port modes in version 6.2 or later.
•
dot1d
—This mode is reserved for backward compatibility with previous STP versions. BPDUs are
sent untagged in 802.1d mode. Because of this, on any given physical interface there can be only one
STPD running in 802.1d mode. This mode supports the industry standard implementation, and can
be used with non-Extreme devices.
•
emistp
—This mode sends BPDUs with an 802.1Q tag having an STPD instance Identifier (StpdID) in
the VLANid field. This is an Extreme proprietary mode, and cannot be used with non-Extreme
devices.
spanning tree name Specifies an STPD name on the switch.
vlan name Specifies a VLAN name.
ports Specifies the port or ports to be included in the STPD. (6.2)
dot1d Specifies the STP port mode of operation to be 802.1d. (6.2)
emistp Specifies the STP port mode of operation to be EMISTP. (6.2)
pvst-plus Specifies the STP port mode of operation to be PVST+. (6.2)
