configure vlan add ports stpd
ExtremeWare Software 7.3.0 Command Reference Guide 1021
configure vlan add ports stpd
configure vlan <vlan name> add ports [all | <portlist>] stpd <spanning tree
name> {[dot1d | emistp | pvst-plus]}
Description
Adds a list of ports within a VLAN to a specified STPD.
Syntax Description
Default
All ports are in
emistp
mode, except those in STPD s0, whose default setting is
dot1d
mode.
Usage Guidelines
This command performs the same function as the
configure stpd add vlan
command with the ports
option included.
This command adds a list of ports within a VLAN to a specified STPD, and specifies the mode for those
ports.
•
dot1d
—In this mode, 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. It can also be used
for backward compatibility with previous STP versions.
•
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.
•
pvst-plus
—This mode implements PVST+ in compatibility with third-party switches running this
version of STP. The STPDs running in this mode have a one-to-one relationship with VLANs, and
send and process packets in PVST+ format.
These port modes are for STP ports, not for physical ports. When a physical ports belongs to multiple
STPDs, it is associated with multiple STP ports. It is possible for the physical port to run in different
modes for different domains for which it belongs.
vlan name Specifies a VLAN name.
all Specifies all of the ports to be included in the STPD.
portlist Specifies the port or ports to be included in the STPD.

dot1d Specifies the STP port mode of operation to be 802.1d.
