Vlan equivalence | HP Network Direr Software Products guide

510CHAPTER 13: VLAN MANAGEMENT

The port on the Switch 3300 connected to the PS Hub has one VLAN, VLAN A, configured on it. Only the Switch 3300 has any awareness of VLANs. The PS Hub and end stations are VLAN unaware devices. 3Com Network Director will infer that the PS Hub and the end-stations are members of VLAN A.

If the user launched the Properties dialog box on one of the end-stations, it would be shown as being a member of VLAN A. See “Properties dialog box” on page 524. Similarly if the user selected the Show VLANs menu option. See “Show VLANs” on page 514 to view VLAN A, the PS Hub and end stations would also be highlighted, not just the Switch 3300.

The rules used for inferring VLAN membership for VLAN-unaware devices are as follows.

■If a port on a VLAN-aware device is a member of VLAN A and all devices hanging off the port are VLAN-unaware, then these devices will be assumed to be members of VLAN A as well. When working out the bounds of the set of VLAN-unaware devices, 3Com Network Director will stop when it reaches a router.

■3Com Network Director can infer that a device is a member of more than one VLAN.

VLAN equivalence

As well as inferring the VLAN membership of VLAN-unaware devices, 3Com Network Director also attempts to match up VLANs configured on VLAN-aware devices, in order to determine whether any two VLANs configured on different devices are in fact the same VLAN. For example, with the network below:
