Figure 3-8. Example of Preventing Specific Ports from Joining Dynamic VLANs
Displaying the Static and Dynamic VLANs Active on the Switch. The
show vlans command lists all VLANs present in the switch.
For example, in the following illustration, switch "B" has one static VLAN (the
default VLAN), with GVRP enabled and port 1 configured to Learn for
Unknown VLANs. Switch "A" has GVRP enabled and has three static VLANs:
the default VLAN, VLAN-222, and VLAN-333. In this scenario, switch B will
dynamically join VLAN-222 and VLAN-333:
3 Static VLANs:
Figure 3-9. Example of Switches Operating with GVRP Enabled
The show vlans command lists the dynamic (and static) VLANs in switch "B"
after it has learned and joined VLAN-222 and VLAN-333.
