Apologies if I am being a bit vague in the following description of my problem. I tried google and google groups but was unable to find anything remotely relevant. I am a UNIX guy and don't have much idea about managed switching and netowrking internals except the basics.
I am a UNIX guy and I needed to deploy a server at a clients place. The server to be deployed was earlier running on a Linux Server connected to a VLAN port configured on a Nortel Passport 8600 Switch over ethernet. The entire networking was done a couple of years ago and the internal network guys don't have any idea.
The system is supposed to be shifted to a brand new hardware. I just needed to remove the ethernet cable from the existing server and plugged in to the new server running Linux again.
The "link LED" failed to come up and the interface was shown as "down". What I had anticipated was that the switch would update its ARP cache after a few minutes, but nothing of that sort happenned. I tried rebooting the switch but even it failed to work. I tried configuring other machines running Windows XP and FreeBSD 6.0, but the end result was the same.
So, I think these might be the reasons:
- Either, the port at the Nortel switch has been configured with the ARP of the Linux Server as the destination, or
- The Nortel Switch is unable to reload its ARP cache.
I am in a fix, and I am trying to find a solution to make the above work without having to modify any configurations on the Nortel Switch.
Looking forward to all possible help,
Thanks and Regards, Animesh NeoLinux Solutions
