ExtremeWare XOS 11.5 Command Reference Guide

configure stpd mode
configure stpd <stpd_name> mode [dot1d | dot1w | mstp [cist | msti
<instance>]]
Description
Configures the operational mode for the specified STP domain.
Syntax Description
Default
The STPD operates in 802.1d 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.
If you configure the STP domain in 802.1D mode, the rapid reconfiguration mechanism is disabled.
If you configure the STP domain in 802.1w mode, the rapid reconfiguration mechanism is enabled. You
enable or disable RSTP on a per STPD basis only. You do not enable RSTP on a per port basis.
If you configure the STP domain in MSTP mode, the rapid reconfiguration mechanism is enabled. You
enable or disable MSTP on a per STPD basis only. You do not enable MSTP on a per port basis. 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 must first configure a Common and Internal Spanning Tree (CIST) before configuring any multiple
spanning tree instances (MSTIs) in the region. You cannot delete or disable a CIST if any of the MSTIs
are active in the system.
