Working with VLANs
If VLAN tag manipulation is configured on the link, the VLAN Mapping Properties area in the Link
Properties window displays the relevant information. For example, in Figure 12-30, the VLAN Mapping
Properties area shows that a one-to-one VLAN mapping for VLAN tag 1709 to VLAN tag 709 is
configured on GigabitEthernet1/1/1 on c7-sw8 on the egress direc tio n.

multiple associations between the logical and physical entities. Actually, however, you are seeing other
views of the original VLAN link.
For example, assume that you have the following situation, as shown in Figure 12-31 and described in
the following paragraphs.
