11–4 MULTILINK ML3000 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL
VLAN REGISTRATION OVER GARP CHAPTER 11: VLAN REGISTRATION OVER GARP
The show-vlan command displays a switch's current GVRP configuration, including the
unknown VLANs.
show-vlan
A port must be enabled and configured to learn for it to be assigned to the dynamic VLAN.
To send advertisements, one or more tagged or untagged static VLANs must be configured
on one (or more) switches with GVRP enabled. The ML3000 software allows a dynamic
VLAN to be converted to a static VLAN with the
static command.
static vlan=<VID>
NOTE
Note
The show vlan type=tag command will display VID in case the VID is not known.
Example 11-1 illustrates how to convert a dynamic VLAN into a static VLAN.
As the following table indicates, a port that has a tagged or untagged static VLAN has the
option for both generating advertisements and dynamically joining other VLANs.

Operations
Learn Enables the port to dynamically join any VLAN
for which it receives and advertisement, and
allows the port to forward the advertisement it
receives.
Block Prevents the port from dynamically joining a
VLAN that is not statically configured on the
switch. The port will still forward advertisements
that were received by the switch on other ports.
Block should typically be used on ports in
insecure networks where there is exposure to
attack - such as ports where intruders can
connect.
Disable Causes the port to ignore and drop all the
advertisements it receives from any source.
