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.
MSTP STPDs use 802.1D BPDU encapsulation mode by default. To ensure correct operation of your
MSTP STPDs, do not configure EMISTP or PVST+ encapsulation mode for MSTP STPDs.
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.
This encapsulation mode supports the following STPD modes of operation: 802.1D, 802.1w, and
MSTP.
●
emistp
—This mode sends BPDUs with an 802.1Q tag having an StpdID in the VLANid field.
This encapsulation mode supports the following STPD modes of operation: 802.1D and 802.1w.
●
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.
This encapsulation mode supports the following STPD modes of operation: 802.1D and 802.1w.
stpd_name
Specifies an STPD name on the switch.
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+.
port_list
Specifies one or more ports or slots and ports.
