MULTISWITCH VLANS

What is meant by Multi-switch VLANs?

·         Simply, Multiswitch VLANs are VLANs in networks that have multiple interconnected switches. For example, if there are 3 VLANS, VLAN1, VLAN2 & VLAN3. All these VLANs can be assigned to any number of switches that are interconnected.

·         The switches need to use VLAN trunking on the links between the switches.

VLAN Trunking means

 VLAN trunking is a link between 2 switches that supports as many VLANs as you require. VLAN trunking can be accomplished using a process called VLAN tagging.

VLAN tagging means

VLAN tagging is a process in which the sending switch adds a VLAN header to the frame before sending it over the trunk. This VLAN trunking header contains a VLAN identifier (VLAN ID) field so that the sending switch can relate the frame with a specific VLAN ID, and the receiving switch can then know the VLAN each frame belong to.

VLAN Trunk port means

VLAN trunk port is a port which is assigned to transmit traffic of all the VLANs that are reachable by a particular switch. Trunk ports mark frames with VLAN tags, either 802.1 Q or ISL.
