Feedback VLAN

VLANs can be viewed as a group of devices on different physical LAN segments which can communicate with each other as if they were all on the same physical LAN segment. That is, a network of computers that behave as if they are connected to the same wire even though they may actually be physically located on different segments of a LAN. VLANs are configured through software rather than hardware, which makes them extremely flexible.

VLAN provides the following benefits for switched LANs:

Multiple Instance is not supported in this release.


12.1 Commands

The list of CLI commands for the configuration of VLAN is as follows:

12.1.1 vlan

Configures a VLAN in the switch and is also used to enter into the Configuration VLAN mode. The no form of the command deletes a VLAN from the switch.


vlan 1-4094


no vlan 1-4094


Mode

Global Configuration

Defaults

1

Example

SEFOS(config)# vlan 4

Notes

Leading zeros must not be entered for VLAN ID.

The default VLAN 1, can not be configured and by default, all ports are members of this VLAN . In order to remove ports from this VLAN, the port has to be configured as an access (untagged) port of some other VLAN. For example, to remove port 7 from the default VLAN, the following config could be done.

SEFOS(config)# interface ext 0/7

SEFOS(config-if)# switchport access vlan 56

% Access VLAN does not exist.,Creating vlan

SEFOS(config-if)# end

SEFOS#
