ExtremeWare XOS 11.5 Command Reference Guide
1215
enable stpd auto-bind
enable stpd <stpd_name> auto-bind vlan <vlan_name>
Description
Automatically adds ports to an STPD when ports are added to a member VLAN.
Syntax Description
Default
The autobind feature is disabled on user-created STPDs. The autobind feature is enabled on the default
VLAN that participates in the default STPD S0.
If you enable autobind and add ports to a member VLAN, those ports are automatically added to the
STPD.
Usage Guidelines
If you create an STPD and a VLAN with unique names, the keywords
stpd
and
vlan
are optional.
You cannot configure the autobind feature on a Netlogin VLAN.
In an EMISTP or PVST+ environment, when you issue this command, any port or list of ports that you
add to the carrier VLAN are automatically added to the STPD with autobind enabled. In addition, any
port or list of ports that you remove from a carrier VLAN are automatically removed from the STPD.
This allows the STPD to increase or decrease its span as you add ports to or remove ports from a carrier
VLAN.
For MSTP, when you issue this command, any port or list of ports that gets automatically added to an
MSTI are automatically inherited by the CIST. In addition, any port or list of ports that you remove
from an MSTI protected VLAN are automatically removed from the CIST. For more information see the
section. For more information, see
“Automatically Inheriting Ports—MSTP Only” on page 1216
.
Carrier VLAN.
A carrier VLAN defines the scope of the STPD, which includes the physical and logical
ports that belong to the STPD and the 802.1Q tag used to transport STP BPDUs in the encapsulation
mode is EMISTP or PVST+. Only one carrier VLAN can exist in a given STPD, although some of its
ports can be outside the control of any STPD at the same time.
NOTE
The StpdID must be identical to the VLANid of the carrier VLAN in that STPD.
stpd_name
Specifies an STPD name on the switch.
vlan_name
Specifies the name of the VLAN to have autobind enabled.
