214 ExtremeWare 7.2e Installation and User Guide
Spanning Tree Protocol (STP)
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. Parameters of only the s0 default STPD are accessible
through this 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
• RSTP 802.1w
Basic 802.1d Configuration Example
The following example creates and enables an STPD named Backbone_st. It assigns the Manufacturing
VLAN to the STPD. It disables STP on ports 1 through 7, and port 12.
create stpd backbone_st
configure stpd backbone_st add vlan manufacturing
enable stpd backbone_st
disable stpd backbone_st port 1-7,12
RSTP 802.1w Configuration Example
Figure 43 is an example of a network with multiple STPDs that can benefit from RSTP. For RSTP to
work, you need to do the following:
• Create an STPD
• Configure the mode of operation for the STPD
•
Create the VLANs and assign the ports
• Add the VLANs to the STPD
•
Configure the port link types
