In this example, a station on port 3 is accessing a server on port 4. To reduce the amount of traffic crossing the switch, the server should be connected to a hub on port 3 instead of a hub on port 4. This keeps traffic localized to the same Fast Ethernet segment.

Creating VLANs

Commands used

set-vbc-domain del-vbc-domain get-vbc-tbl set-sec-vlan del-sec-vlan get-svlan-tbl

Sets up a Virtual Broadcast Domain (VBD).

Deletes a VBD.

Displays the VBD table.

Sets up a security VLAN.

Deletes a security VLAN.

Displays the security VLAN table.

There are two types of VLANs:

Security VLANs (SVLANs). Ports in an SVLAN can exchange packets only with other ports in the same SVLAN.

VBDs: Ports in a virtual broadcast domain can exchange packets only with other ports in the same VBD. However, they can see broadcast frames from other ports in the same VBD.

Use only one type. Configuring both types in the same switch can lead to unpredictable traffic patterns.

If you want a device to talk to multiple VLANs (for example, a management workstation), apply a custom filter to the device. See page 24 for instructions.
