VLAN & Bridge
Device>Configure>VLAN & Bridge
Virtual LANs (VLANs) allow you to logically group resources independent of
their physical location. This arrangement of resources, and the ports to which
they are attached, is called a logical grouping. A logical group of ports is
called a VLAN. Ports or groups of ports in a VLAN are called members. VLANs isolate
all traffic, including broadcasts and multicasts, from being propagated to
members of other VLANs. A Token Ring VLAN comprises Token Ring Bridge Relay Functions (TrBRFs) and Token Ring
Concentrator Relay Functions (TrCRFs).
If the switches are interconnected by a port called an Inter-Switch Link
(ISL), you can specify which VLANs are allowed to flow through the ISL.
You can use the VLAN & Bridge option to configure and view VLANs and their
members.
The table on the left side of the dialog box displays the following
information:
VLAN Name (vtpVlanName)
ASCII name associated with the VLAN; synonymous with the VLAN’s emulated LAN name on LAN emulation (LANE) trunks.
VLAN Type (vtpVlanType)
VLAN type. Possible values are Ethernet, Fiber Distributed Data Interface
(FDDI), fddiNet, Token Ring Bridge Relay Function (TrBRF), and Token Ring
Concentrator Relay Function (TrCRF).
VLAN State (vtpVlanState)
Current state of the VLAN. Possible values are Operational and Suspended.
VLANs in Operational state are functional. VLANs in Suspended state do not pass
packets.
Click OK to add a new VLAN, or click Cancel to close the dialog box without making any changes.
