VLANs tab for switches with only one factory-default VLAN configured
If a switch has only one configured VLAN and all ports are untagged members of this VLAN, then this is considered to be a factory-default switch and a VLAN-unaware device i.e. the user has not explicitly configured any VLANs on this switch. The VLANs tab on the Properties dialog box for this type of switch differs from the previous case where the switch had VLANs explicitly configured:
Figure 277 Switch with Only One Configured VLAN
The top section is similar to the VLANs tab for a VLAN-aware switch in that it shows the VLANs configured on the switch – in this case only one.
The combo box in the bottom section lists those VLANs that 3Com Network Director has inferred that this switch is a member of. See “VLAN membership inference” on page 509. The text below the combo box is context-sensitive and updates when a VLAN is selected from the combo-box. It displays the nearest VLAN-aware switches that have the selected VLAN configured.
