Connecting Common VLANs Between Switch Units
In the Switch 2000 TR, you typically connect VLANs to other Switch 2000 TRs and units using backbone ports. This allows the Switch to forward all frames with an unknown address to the rest of the network, and it also stops the Switch Database from becoming full if there are more than 500 addresses in the net- work. Note that you normally require one backbone port per VLAN.
In addition, to make the
NOTE: VLTs can only be used for links between SuperStack II Switch 2000 TR units. You cannot use VLTs for
If you specify that a backbone port on one VLAN is part of a VLT, that backbone port becomes a back- bone port for all the VLANs on the Switch, even if they had no backbone port before. If you subse- quently disable the VLT function on that port, the port becomes the backbone port for the Default VLAN (VLAN 1) and all other VLANs lose their backbone ports.
Using Non-routable Protocols
If you are running
within one VLAN will not be able to communicate with devices in a different VLAN.
Using Unique MAC Addresses
If you connect a server with multiple network adapt- ers to the Switch, we recommend that you configure each network adapter with a unique MAC address.
Extending VLANs into an ATM Network
If the Switch has an ATM

To set up this configuration:
1Use the VT100 screens or VLAN Server database to: a Place ports
b Place ports
2Connect a port in VLAN 1 to the router.
3Repeat steps 2 and 3 for VLAN 2.
