Allowing Inter-VLAN Communication

Individual switch ports may be given the status of “Global Port”. Global ports can communicate with all VLANs. This feature has many uses:

•Executives or administrators in a company can give their switch ports Global port status so they can access all VLANs.

•A server attached to a Global port can serve many VLANs.

•Indirect communication between VLANs can be arranged. Via a server attached to the Global port, packets (mail, for example) may be transferred to any VLAN.

To give the status of Global Port to a switch port:

1From the Chassis View, open the Configuration menu and select Virtual LANs.

2Arrange the windows so you can see the Virtual LANs for Device dialog box and the Chassis View at the same time.

3From the Virtual LANs list, select Global (# 255).

4In the Chassis View, select the switch port you want to set to Global Port status (use CTRL-click to select multiple switch ports).

5Click Add Zoom Sel. The selected switch parts are assigned to Global and automatically deleted from any other VLAN.
