Configure VLANs

Adding virtual LAN (VLAN) support to a Layer 2 switch offers 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, and 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, users can be
grouped by logical function instead of physical location.
Each VLAN in a network is assigned 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 can 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 given port can handle
traffic for more than one VLAN, but it can support only one default VLAN ID.
You can define VLAN groups stored in the VLAN membership table. Each switch in the
M4300 Series and M4300-96X family supports up to 1024 VLANs. VLAN 1 is created by
default and is the default VLAN of which all ports are members.

Configure Basic VLAN Settings

The internal VLAN is reserved by a port-based routing interface and invisible to the end user.
Once these internal VLANs are allocated by the port-based routing interface, they cannot be
assigned to a routing VLAN interface.
