configure stpd add vlan
ExtremeWare XOS 10.1 Command Reference Guide 371
configure stpd add vlan
configure stpd <stpd_name> add vlan <vlan_name> ports [all | <port_list>]
{[dot1d | emistp | pvst-plus]}
Description
Adds all ports or 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 802.1d mode.
Usage Guidelines
After you have created the STPD and the VLAN with unique names, the keywords stpd and vlan are
optional.
This command performs the same function as the configure vlan add ports stpd command.
This command adds a list of ports within a VLAN to a specified STPD provided the carrier VLAN
already exists on the same set of ports. You can also specify the encapsulation mode for those ports. If
the specified VLAN is not the carrier VLAN, and the specified ports are not bound to the carrier VLAN,
an error message is displayed. The following sample output is similar to the error message displayed:
Error: Cannot add VLAN default port 7:256 to STP domain
Care must be taken to ensure that ports in overlapping domains do not interfere with the orderly
working of each domain’s protocol.
You can create STP domains using the create stpd command.
You can specify the following STP encapsulation modes:
• dot1d—This mode is reserved for backward compatibility with previous STP versions. BPDUs are
sent untagged in 802.1d mode. Because of this, any given physical interface can have only one STPD
running in 802.1d mode.
• emistp—This mode sends BPDUs with an 802.1Q tag having an STPD instance Identifier (StpdID) in
the VLANid field.
• 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.
stpd_name Specifies an STPD name on the switch.
vlan_name Specifies a VLAN name.
all Specifies all of the ports to be included in the STPD.
port_list Specifies the port or ports to be included in the STPD.
dot1d Specifies the STP encapsulation mode of operation to be 802.1d.
emistp Specifies the STP encapsulation mode of operation to be EMISTP.
pvst-plus Specifies the STP encapsulation mode of operation to be PVST+.
