I have a CISCO6506-E, with Sup II with PFC and an 8-Port GBIC connected to a 4506 on GBIC.
I have tagged the vlan, configure the trunk but I cannot ping the 4506 from the 6506. The 6506-E is just a forwarding switch (L2). What coud be the problem. I have check the status, no vlan mismatch, trunk is good, CDP is good.
I am sorry I can't post it to you now as I am not at the site.
But to answer your question i have checked everything from the physical layer and other features such as trunk, vlan, cdp and there are no error. When I do a sh trunk, I can see that the trunk is up, the vlan is correct.
Could it be that I state the command set trunk negotiation disable on both switch cause this problem. Both the LED on the GBIC are lighted and green. If I enable negotiation, both the link will go down.
I do not think there is an command like "set trunk negotiate disable" I think you might have given command "set trunk nonegotiate" and it should not create any problem as it just bring the trunk up without sending any DTP packet.
You cannot put negotiate on both sides and that is the probable reason trunk is going down. Negotiate keyword is just to let the switch know what is the encapsulation cofnigured on other side i.e isl or dot1q and it will work accordingly.
Can you please explain what have you configured as trunk mode on other side? I think we are lacking in some config if you just post the related config it will be of help.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
