Autonegotiation time on a Cisco 5500 switch

Nov 14, 2006 1 Replies

All,



I'm having a problem with a server of mine.



It's a Linux server that periodically checks to see if it can bring up its ethernet interface. It waits 3 seconds and then checks to see if a link was detected. Regardless of the outcome, it brings the network interface back down. The server and the switch are both set to autonegotiate.



I cannot change the above process, so I was wondering if there are any configuration parameters that I can tune to increase the speed of the autonegotiation process.



The ethernet switch in question is a Cisco 5500.



Many thanks for any suggestions



Ensure that portfast is enabled on the port, or spanning tree disabled completely on it, and ensure that trunk autonegotiation is off for the port.

And, of course, that you don't have anything like ppp encapsulation set for the link ;-)
