IES-1248-51/51A/53 User’s Guide
316 Chapter 48 IEEE 802.1Q Tagged VLAN Commands
This command adds or modifies an entry in the static VLAN table. Use the switch vlan
show
command to display your configuration. An example of a configuration is shown next.
48.4.4.1 Modify a Static VLAN Table Example
The following is an example of how to modify a static VLAN table.
48.4.4.2 Forwarding Process Example
Tagged Frames
1 First the IES-1248 checks the VLAN ID (VID) of tagged frames or assigns temporary
VIDs to untagged frames (see Section 48.4.2 on page 314).
2 The IES-1248 checks the frame’s source MAC address against the MAC filter.
3 The IES-1248 then checks the VID in a frame’s tag against the SVLAN table.
4 The IES-1248 notes what the SVLAN table says (that is, the SVLAN tells the IES-1248
whether or not to forward a frame and if the forwarded frames should have a tag).
5 Frames might be dropped if they are sent to a CPE (customer premises equipment) DSL
device that does not accept tagged frames.
Untagged Frames
<F<T|U>| =
The <F> stands for a fixed registrar administration control flag
and registers a <port #> to the static VLAN table with <vid>.
For a fixed port, you also have to specify <T|U>, the tag control
flag.
<T> has the device add an IEEE 802.1Q tag to frames going out
through this port(s).
<U> has the device send frames out through this port(s) without
an IEEE 802.1Q tag.
|X|N> =
This is the registrar administration control flag.
<X> stands for forbidden and blocks a <port #> from joining the
static VLAN table with <vid>.
<N> stands for normal and confirms registration of the <port #>
to the static VLAN table with <vid>. This is used in GVRP
applications.
[name] =
A name to identify the SVLAN entry.
