Configure STP on the Switch

To configure basic STP:

Create one or more STPDs using the command:
create stpd stpd_name {description stpd-description}
Add one or more VLANs to the STPD using the command:
configure stpd stpd_name add vlan vlan_name | vlan_list ports [all | port_list] {[dot1d | emistp | pvst-plus]}
Define the carrier VLAN using the command:.
configure stpd stpd_name tag stpd_tag

Note
The carrier VLAN's ID must be identical to the StpdID.
Enable STP for one or more STPDs using the command:
enable stpd {stpd_name}
After you have created the STPD, you can optionally configure STP parameters for the STPD.

Note
You should not configure any STP parameters unless you have considerable knowledge and experience with STP. The default STP parameters are adequate for most networks.
The following parameters can be configured on each STPD:
- Hello time (In an MSTP environment, configure this only on the CIST.)
- Forward delay
- Max age (In an MSTP environment, configure this only on the CIST.)
- Max hop count (MSTP only)
- Bridge priority
- Domain description
- StpdID (STP, RSTP, EMISTP, and PVST+ only)
- MSTI ID (MSTP only)
The following parameters can be configured on each port:
- Path cost
- Port priority
- Port mode
Note

The device supports the RFC 1493 Bridge MIB, RSTP-03, and Extreme Networks STP MIB. Parameters of the s0 default STPD support RFC 1493 and RSTP-03. Parameters of any other STPD support the Extreme Networks STP MIB.

If an STPD contains at least one port not in 802.1D (dot1D) mode, the STPD must be configured with an StpdID.

The following section provides more detailed STP configuration examples, including 802.1D, EMISTP, RSTP, and MSTP.
