Spanning Tree Protocol

Configuring Multiple Spanning Tree Groups

This section explains how to assign each VLAN to its own Spanning Tree Group on the switches 1 and 2.

By default, Spanning Tree Groups 2-127 are empty, and Spanning Tree Group 1 contains all configured VLANs until individual VLANs are explicitly assigned to other Spanning Tree Groups. Except for the default Spanning Tree Group 1, which may contain more than one VLAN, Spanning Tree Groups 2-128 may contain only one VLAN each.

NOTE: Each instance of Spanning Tree Group is enabled by default.

Configuring Switch 1 (CLI example)

1.	Configure port and VLAN membership on Switch 1 as described in the “Configuring ports and
	VLANs on Switch 1 (CLI example)” section, in the “VLANs” chapter of this guide.
2.	Add VLAN 2 to Spanning Tree Group 2.
		>> /cfg/l2/stp 2	(Select Spanning Tree Group 2)
		>> Spanning Tree Group 2# add 2	(Add VLAN 2)
	VLAN 2 is removed from Spanning Tree Group 1.
3.	Apply and save.
		>> apply	(Apply the port configurations)
		>> save	(Save the port configurations)

Configuring Switch 2 (CLI example)

	2 (CLI example)” section in the “VLANs” chapter of this guide.
2.	Add VLAN 2 to Spanning Tree Group 2.
		>> /cfg/l2/stp 2	(Select Spanning Tree Group 2)
		>> Spanning Tree Group 2# add 2	(Add VLAN 2)
	VLAN 2 is removed from Spanning Tree Group 1.
3.	Apply and save.
