Dynamic VLAN Creation-Registration / GVRP utilization

Did you enable GVRP on the 6024?  Earlier I discussed GVRP on this thread.  Perhaps the information there would help you.

Yes I did.  I'll clear the switch settings and configure it again.  Perhaps I'm doing something wrong.

Thanks!

I'm not exactly sure what you mean, but if you are asking if you can enable GVRP only on one switch and expects somehow that it will learn VLANs from another switch that's not running GVRP, then the answer is no.

GVRP is a protocol and therefore requires that all participants must also be running the same protocol in order to operate correctly.

I'm expecting somehow that it will learn VLANs from itself running GVRP.  In this case I have only one switch.  Is it possible?

I did a trunk between two ports on the same switch ( port G1 and G2 of PC 6024F ) and I assigned to these ports VLAN 100. Then I connected two hosts ( with 802.1q NIC properly configured and VLAN 100 assigned to it )  to ports, for instance, 17 and 18 respectively on 6024F.  At monitoring terminal nothing occurred and I can't ping each other.

Thanks once again,

This is a very strange setup and I don't think it will work.  If you created a loop like this then you basically caused a bridging loop on the switch which will cause STP (spanning-tree) to disable one of these ports so probably only one of those trunk ports is actually active.

Now why are you doing this?  If you just want to connect two hosts to two ports on the switch and have them talk to each others they can already through normal switching.  Why are you creating a networking loop using the two Gigabit ports?

So let's say you don't connect those trunk ports at all.  Now if you have the two hosts on the two ports (17 & 18) and if those NICs are on VLAN 100 then you can configure the two ports to VLAN 100 and they will be able to pass traffic between the two hosts.

Note that if the NIC supports GVRP and you enable GVRP on the switch it should also work.  You do not need to configure that strange loop with the two gigabit ports.  The NIC & switch will use GVRP to communicate the VLAN config with each others.  Please also review the discussion of GVRP at this discussion thread: http://forums.us.dell.com/supportforums/board/message?board.id=pc_managed&message.id=6178

Please post the configuration for both of the 5324 and for the 6024.  Also on your NICs, are you configuring the NICs to send VLAN tag or untag traffic?  Please give the config of the NICs including IP/Mask & Gateway IP.

Dear Cuong,

I've reinstalled the Windows 2000 Pro and PROSet software on my workstations and I've configured the VLANs on NICs...  All hosts can ping each other.

Thanks for your help.
