Inter-Switch VLAN or ISVLAN

The inter-switch VLAN conforms to the standard IEEE 802.1q, which describe the method of passing tagged frames through a physical link. To satisfy the need, the frame format should be changed and 4 more bytes are added to the frame header between the end of address field and the frame type.

Tag Field Format

This is a 4 bytes long field divided into two sub-fields of 2 bytes respectively named TPID and TCI.

∙TPID is the Tag Protocol Identifier which identifies the tag type of the frame.

∙TCI contains the user priority bits and the VID (VLAN Identifier).

Principles of ISVLAN

To configure a tagged port that could carry specific tagged frames you need the necessary information about how our ISVLAN works.

∙The port declared as tagged port should belong to all the VLAN’s you are willing to interconnect between multiple switches with the command set-tag-outbound-mode.

∙Once you have declared the tagged port you can create the specific VLAN’s using the command set provided in this section.

Viewing the ISVLAN Mode

get-tag-outbound-mode

The get-tag-outbound-modecommand shows the VLAN Tagging ports’ state. A “T” indicates that the Tagging mode off the port is on, “A” indicates that the Tagging is off.

get-tag-outbound-mode {runnvram}

Example
