Configuring EAPS with STP
ExtremeWare XOS 11.0 Concepts Guide 193
6 Configure the STPD and add all protected VLANs to STPD using the following command:
configure stpd <stpd_name> add vlan <vlan_name> ports all
7 Enable STPD using the following command:
enable stpd <stpd_name>
Configuring EAPS Master Node with STP Disabled
You add the STP Carrier VLAN you created to the EAPS Domain only on the EAPS master node, as a
protected VLAN.
Use the following command:
configure eaps <name> add protect vlan <vlan_name>
Configuring EAPS with STP in 802.1D Encapsulation Mode
This section discusses how to configure STP with 802.1D encapsulation in this situation. You use the
802.1D encapsulation mode when you are running untagged STP Carrier VLAN.
Configuring an STP Carrier VLAN on all switches
To configure an STP Carrier VLAN on all switches, follow these steps with 802.1D encapsulation:
1 Create an STP Carrier VLAN to carry STP BPDUs using the following command:
create vlan <vlan_name> {vr <vr-name>}
2 Add the EAPS ring ports to STP Carrier VLAN using the following command:
configure vlan <vlan_name> add ports <port_list>
If the ports you want to add are still in the default VLAN, you must first delete those ports from the
default VLAN because a port can belong to only one untagged VLAN.
3 Add the STP Carrier VLAN you created to the EAPS domain as a protected VLAN using the
following command:
configure eaps <name> add protect vlan <vlan_name>
Configuring EAPS VLANs for Switches with STP Enabled
NOTE
EAPS master nodes should be configured only on a switch not running STP; enable STP only on the
common links.
To configure EAPS VLANs for switches running STP, follow these steps with 802.1D encapsulation:
If you use the default “s0” STP domain, skip to step 3.
1 Create a Spanning Tree Domain (STPD) using the following command:
create stpd <stpd_name>
2 Specify STP 802.1d mode using the following command:
configure stpd <stpd_name> default-encapsulation dot1d
