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:
• Removes ports from the VLAN Default that will be added to VLAN Engineering.
• Creates the VLAN Engineering.
• Configures the VLANid.
• Adds ports to the VLAN Engineering.
• Creates an STPD named Backbone_st.
• Configures the default encapsulation mode of dot1d for all ports added to STPD Backbone_st.
• Enables autobind to automatically add or remove ports from the STPD.
• Assigns the Engineering VLAN to the STPD.
• Assigns the carrier VLAN.
• Enables STP.
configure vlan default delete ports 2:5-2:10
create vlan engineering
configure vlan engineering tag 150
configure vlan engineering add ports 2:5-2:10 untagged
create stpd backbone_st
configure stpd backbone_st default-encapsulation dot1d
enable stpd backbone_st auto-bind vlan engineering
configure stpd backbone_st tag 150
enable stpd backbone_st
By default, the port encapsulation mode for user-defined STPDs is emistp. In this example, you set it to
dot1d.
