Spanning Tree Protocol (STP)
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
• Forward delay
• Max age
• Bridge priority
• StpdID
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.
NOTE
If an STPD contains at least one port not in dot1D mode, the STPD must be configured with an StpdID.
STP Configuration Examples
This section provides three configuration examples:
• Basic 802.1d STP
• EMISTP
• RSTP 802.1w
Basic 802.1d Configuration Example
The following example:
• Creates the VLAN Engineering
• Configures the VLANid
• Adds ports to the VLAN Engineering
• Creates an STPD named Backbone_st
• Enables autobind to automatically add or remove ports from the STPD
