Trunk on mini-GBIC ports

Hi everybody,

I'm using Switch Procurve 2510G with 2 Vlans.

If I configure trunks in RJ-45 ports, all works well.

But now I have to connect 2 switches with more than 100m distance so I have to use mini-GBIC.

I configure mini-GBIC ports as trunk but it doesn't work.

I tryied to connect not trunked mini-GBIC ports and the communication is ok.

Is it possible to use mini-GBIC ports as trunked? How can I configure them?

Thank's a lot!

Re: Trunk on mini-GBIC ports

Yep it should be configured just like any other rj45 port. Can you show us your config?

I've the same configuration on both switches.

I tryied to connect the same port (23) on both switch but it doesn't work.

After that I deleted Trk3 to Trk6, I assigned them to VLan 1 and the connection works, but i can't send VLan2 packets...
