Gvrp problem

When you created VLAN 100, did you add this VLAN to any port?  Is that port connected to anything?  Until the VLAN becomes active it is not going to be advertised to the other switch.  Only active interfaces are advertised.  Also, make sure that the port(s) you add to the new VLAN 100 is also enabled for GVRP otherwise it will not be advertised.

So the rules are:

• All ports participating in GVRP must be enabled.
• To advertise the VLAN, it must have member ports which must be GVRP enabled.
• The port must be active and must not be disabled by spanning tree.

Basically the VLAN interface must be active and it must have GVRP enabled member ports and it must be part of the spanning tree (must not be disabled by spanning tree).

Cuong.

Thank you,

 that solve the problem. When I connected a PC to the switch port, the vlan 100 was propagated to the other switch. I have one more question, is it possible to add ports to this dynamicly created vlan? When I tried to add an access port to vlan 100, I got this message :

''VLAN 100: VLAN was not created by user.''

Where do you see that message?  On the system that you are trying to advertise to or on the system where you are advertising from?

If you are on the system where the VLAN was created dynamically via GVRP advertisement then no you cannot add ports to this VLAN since it was learned in GVRP and may disappear at anytime.  If you need to put ports into this VLAN you need to add it permanently to the switch.

Cuong.

Yes, the message was on the destination switch,

Thank you for your help

I don't think that will work.  You have to have Cisco doing GVRP also to make it work.  GVRP is a protocol that must be run on both switches.  Since Cisco must run either GVRP or VTP not both, I don't think this will work.

Cuong.
