We have a customer connected to Gi-1/0/1 on a TA1424 running J08.01/C01.16. They have been trying to cut their service off a Cisco device to a Silver Peak but they lose link when they attempt. Customer asked me about a separate auto-negotiate setting than the speed/duplex. I see a command for auto-negotiate enable, but I've tried to see it in the show run verbose or the show run interface when I issue "no auto-negotiate enable" on a different gi interface. I see no difference. The customer wants to be sure auto-negotiate is disabled when they attempt the second cut. Currently we are set for speed 1000 FD. Will issuing the no auto-negotiate command on the working circuit disable any auto-negotiate? I see no option for auto within the speed setting options.
