Configure VLANs
Adding virtual LAN (VLAN) support to a Layer 2 switch provides some of the benefits of both
bridging and routing. Like a bridge, a VLAN switch forwards traffic based on the Layer 2
header, which is fast. Like a router, it partitions the network into logical segments, which
provides better administration, security, and management of multicast traffic.

By default, all ports on the switch are in the same broadcast domain. VLANs electronically
separate ports on the same switch into separate broadcast domains so that broadcast
packets are not sent to all the ports on a single switch. When you use a VLAN, you can group
users by logical function instead of physical location.

users by logical function instead of physical location.
Each VLAN in a network has an associated VLAN ID, which appears in the IEEE 802.1Q tag
in the Layer 2 header of packets transmitted on a VLAN. An end station might omit the tag, or
the VLAN portion of the tag, in which case the first switch port to receive the packet can either
reject it or insert a tag using its default VLAN ID. A port can handle traffic for multiple VLANs,
but it can support only one default VLAN ID.

Manage Custom VLANs
The smart switch supports up to 128 VLANs. VLAN 1 is the preconfigured default VLAN, and
all port are untagged members by default. VLAN

2 (VoiceVLAN) and VLAN 3 (Auto-Video)
are also preconfigured VLANs, but no ports are part of these VLANs by default. You cannot
delete VLAN 1, VLAN 2, or VLAN 3.
delete VLAN 1, VLAN 2, or VLAN 3.
Note:
By default, all ports are untagged members of VLAN 1, the default
VLAN. However, ports that you make members of link aggregation
groups (that is, physical interfaces that function as trunk members)
lose their membership of the default VLAN. For more information
about link aggregation groups, see
