Chapter 5: Spanning Tree
79BMD00041, November 2008
As an example, assume that port 1 belongs to VLAN 2, and VLAN 2 belongs to STG 2.
When you remove port 1 from VLAN 2, port 1 is also removed from STG 2. The port
moves to the default VLAN 1.
However, if port 1 belongs to both VLAN 1 and VLAN 2 and both VLANs belong to
STG 1, removing port 1 from VLAN 2 does not remove port 1 from STG 1 because
VLAN 1 is still a member of STG 1.
An STG cannot be deleted, only disabled. If you disable the STG while it still contains
VLAN members, Spanning Tree will be off on all ports belonging to that VLAN.
The relationship between port, trunk groups, VLANs, and Spanning Trees is shown in
Table 5-1.
