Managing the Switch
Virtual LANs (VLANs)
Virtual LANs or VLANs can be roughly equated to a broadcast
domain. More specifically, VLANs can be seen as analogous to a
group of end stations, perhaps on multiple physical LAN segments,
that are not constrained by their physical location and can
communicate as if they were on a common LAN.
The switch conforms to the IEEE 802.1Q specification for a VLANaware
bridge in a virtual bridged local area network. The 6000 switch
uses port-based VLANs, whereby VLAN membership of each
untagged frame is determined by noting the port on which it arrives.
The slot identification is not needed when configuring VLANs.
The switch supports 2,048 VLANs regardless of the number of ports
available on the system. However, any of the 4,094 VLAN IDs may
be assigned to the 2,048 VLANs.
Note
802.1Q VLANs and IGMP Snooping both share resources
which might be limited with Link Aggregation. Link Aggregation
consumes more resources and depending on your
network configuration, might restrict the number of VLANs
that can be created. instructions on configuring IGMP
Snooping are included in this chapter.
Creating a VLAN
To create a VLAN
1 At the prompt, type set priv to enter privileged mode.
2 Associate a port on the switch to one or more VLAN identifiers
(VID). VLANs are assigned a number from 1 to 4,094. This
number becomes the VID. Type vlan VID create. The ports do
not have to exist in order to create a VID.
