Enabling 802.1W Draft 3
802.1W Draft 3 is disabled by default. The procedure for enabling the feature differs depending on
whether single STP is enabled on the device.
NOTE
STP must be enabled before you can enable 802.1W Draft 3.
Enabling 802.1W Draft 3 when single STP is not enabled
By default, each port-based VLAN on the device has its own spanning tree. To enable 802.1W Draft
3 in a port-based VLAN, enter commands such as the following.
PowerConnect(config)#vlan 10
PowerConnect(config-vlan-10)#spanning-tree rstp
Syntax: [no] spanning-tree rstp
This command enables 802.1W Draft 3. You must enter the command separately in each
port-based VLAN in which you want to run 802.1W Draft 3.
NOTE
This command does not also enable STP. To enable STP, first enter the spanning-tree command
without the rstp parameter. After you enable STP, enter the spanning-tree rstp command to enable
802.1W Draft 3.
To disable 802.1W Draft 3, enter the following command.
PowerConnect(config-vlan-10)#no spanning-tree rstp
Enabling 802.1W Draft 3 when single STP is enabled
To enable 802.1W Draft 3 on a device that is running single STP, enter the following command at
the global CONFIG level of the CLI.
PowerConnect(config)#spanning-tree single rstp
Syntax: [no] spanning-tree single rstp
This command enables 802.1W Draft 3 on the whole device.
NOTE
This command does not also enable single STP. To enable single STP, first enter the spanning-tree
single command without the rstp parameter. After you enable single STP, enter the spanning-tree
single rstp command to enable 802.1W Draft 3.
To disable 802.1W Draft 3 on a device that is running single STP, enter the following command.
PowerConnect(config)#no spanning-tree single rstp
Single Spanning Tree (SSTP)
By default, each port-based VLAN on a Dell PowerConnect device runs a separate spanning tree,
which you can enable or disable on an individual VLAN basis.
