512 CHAPTER 13: VLAN MANAGEMENT
3Com Network Director explicitly does not use any IP subnet information
associated with a VLAN to infer VLAN (non)equivalence or use VLAN
names to override (non)equivalent IDs.Consider the following network:
Figure 265 Network Example
Because the links are tagged, 3Com Network Director will be able to
deduce that the VLANs with ID 2 on each of the three switches are the
same. Similarly with VLAN ID 3. However, the user has not used
consistent names when creating the VLANs. 3Com Network Director will
pick one of the three names for VLAN ID 2 to represent the VLAN in the
3Com Network Director user interface. For example, 3Com Network
Director might list the VLANs on the network as:
eng VLAN (ID=2)
admin VLAN (ID=3)
