Configuring GVRP On a Switch

Figure 3-5.

Example Showing Default Settings for Handling Advertisements

Use the arrow keys to select the port you want, and the Space bar to select

Unknown VLAN option for any ports you want to change.

When you finish making configuration changes, press

[Enter]

, then

[S]

(for

ave

) to save your changes to the Startup-Config file.

The Unknown VLAN

fields enable you to

configure each port to:

–

Learn - Dynamically

join any advertised

VLAN and advertise all

VLANs learned

through other ports.

–

Block - Do not

dynamically join any

VLAN, but still

advertise all VLANs

learned through other

ports.

–

Disable - Ignore and

drop all incoming

advertisements and do

not transmit any

advertisements.
