Syntax:

vlan <vlan-id> fixed <port-list> forbidden <port-list> name <name-str> normal <port-list> untagged <port-list> no fixed <port-list>

no forbidden <port-list> no untagged <port-list>

where

 

 

<vlan-id>

=

The VLAN ID [1 – 4094].

<name-str>

=

A name to identify the SVLAN entry.

<port-list> =

This is the switch port list.

•Enter fixed to register the <port-list>to the static VLAN table with <vlan-id>.

•Enter normal to confirm registration of the <port-list>to the static VLAN table with

<vlan-id>.

•Enter forbidden to block a <port-list>from joining the static VLAN table with

<vlan-id>.

•Enter no fixed or no forbidden to change <port-list>to normal status.

•Enter untagged to send outgoing frames without a tag.

•Enter no untagged to tag outgoing frames.

29.5.4.1Modify a Static VLAN Table Example

The following example configures ports 1 to 5 as fixed and untagged ports in VLAN 2000.

Figure 138 Modifying Static VLAN Example

ras (config)# vlan 2000

ras (config-vlan)# fixed 1-5 ras (config-vlan)# untagged 1-5

29.5.4.2 Forwarding Process Example

Tagged Frames

1First the switch checks the VLAN ID (VID) of tagged frames or assigns temporary VIDs to untagged frames.

2The switch then checks the VID in a frame’s tag against the SVLAN table.

3The switch notes what the SVLAN table says (that is, the SVLAN tells the switch whether or not to forward a frame and if the forwarded frames should have tags).
