Solved: Speed/duplex settings on ISR G2 EHWIC-1GE-SFP-CU

Christopher Bell · ‎07-22-2013

Cisco 3945 running 15.3(2)T with 1 x EHWIC-1GE-SFP-CU. Configuring the interface as such:

conf t

int g0/0/0

speed 1000

duplex full

Does not yield those settings int the configuration. Is this by design?

I am not sure that I correctly or completely understand your question. Are you saying that the interface does not wind up at Gig speed or at full duplex? Or are you just saying that you do not see that text in running config? What does the output of show interface Gi0/0/0 indicate.

I am guessing that since Gig speed and full duplex are the default settings for the interface that it may not show up in running config.

The later is correct, sorry for not being clear. The hard set 1000/full does not show up in the config. For every other Cisco interface I've ever configured, anything but "auto-negotiate" is always indicated in the config since it's not default. Our ISP was insisting that we turn off auto-neg, and I really couldn't show them in the config that we had. Just wanted to make sure I was configuring everything correctly.
