510 ExtremeWare XOS 11.0 Command Reference Guide
STP Commands
configure stpd ports mode
configure stpd <stpd_name> ports mode [dot1d | emistp | pvst-plus]
<port_list>
Description
Configures the encapsulation mode for the specified port list.
Syntax Description
Default
Ports in the default STPD (s0) are
dot1d
mode. Ports in user-created STPDs are in
emistp
mode.
Usage Guidelines
If your STPD has the same name as another component, for example a VLAN, Extreme Networks
recommends that you specify the identifying keyword as well as the name. If your STPD has a name
unique only to that STPD, the keyword
stpd
is optional.
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 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.
Example
The following command configures STPD s1 with PVST+ packet formatting for slot 2, port 1:
configure stpd s1 ports mode pvst-plus 2:1
