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 ML810 software allows a dynamic VLAN
to be converted to a static VLAN with the
static vlan=<VID>
The
show vlan type=tag
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.

CHAPTER 11: VLAN REGISTRATION OVER GARP
Operations
Enables the port to dynamically join any VLAN
for which it receives and advertisement, and
allows the port to forward the advertisement it
receives.
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.
Causes the port to ignore and drop all the
advertisements it receives from any source.
