VLAN Port-Based (CLI)

VLAN Port-Based (CLI)
A Virtual LAN (VLAN) is a logical grouping of nodes for the purpose of limiting a broadcast domain to specific
members of a group without physically grouping the members. The VLAN allows you to isolate network traffic
so that only members of the VLAN could receive traffic from the same VLAN members. Basically, creating a
VLAN from a switch is the logical equivalent of physically reconnecting a group of network devices to another
Layer 2 switch, without actually disconnecting these devices from their original switches.
The ES7506 supports IEEE 802.1Q VLAN, which is also known as Tag-Based VLAN. This Tag-Based VLAN
allows a VLAN to be created across different switches. IEEE 802.1Q tag-based VLAN makes use of VLAN
control information stored in a VLAN header attached to IEEE 802.3 packet frames. This tag contains a
VLAN Identifier (VID) that indicates which VLAN a frame belongs to. Since each switch only has to check a
frame's tag, without the need to dissect the contents of the frame, this also saves a lot of computing resources
within the switch.
Optionally, you can use the web user interface for configuration, see
The following table provides detailed information about command lines for VLAN port configuration, VLAN
configuration, and VLAN table display.
