Port stats on a router and a switch

phatrik

I'm using packet tracer to get some hands on experience. While I noticed I can see a port speed an duplex on a switch with "show int fa0/1", I can't seem to find the same information on a router. At first I thought it might have something to do with the fact I hard coded the speed/duplex, but even when setting a port on the router for autoneg I still can't see the info using a "show int" command.

Also, I seem to remember for switches there's a command which would bring up a one-liner, showing something like a-100 and a-full for auto negotiation, but I can't seem to figure out what that command is. I looked at show int/show ip int but couldn't find the right command, I figure I must be overlooking something.



TIA

ATL-EDGE-1#sh int fa0/0 | inc Mb/s
Half-duplex, 10Mb/s, 100BaseTX/FX

What he has done is the command.

Show Interface FastEthernet0/0 | inc Mb/s

The pipe (|) allows you to modify output to show specific things.

I don't know what point you're trying to make. See attached screenshot. There's *definitely* no speed/duplex info in the show int output.

Type this into the console without the the quotation marks

"Show Interface FastEthernet0/0 | inc Mb/s"

If you don't have time to look at the screenshot I posted, please don't bother replying.

The point is that is the command you use to determine the speed/duplex on a router.

You are using a simulator called Packet Tracer. Simulators make mistakes and do not always show the real output. I have the output of a real 2621XM in front of me.

I don't get why you're so annoyed. I'm telling you the answer.

Go to console, type in "Show int fa0/0 | include duplex" and it should tell you. Does on my 2621XM

lol. So is life. Off to the great outdoors.

Does it really matter, Is rep even visible anywhere?

In my original post, I made it clear I was already using "show int faX/X". The fact you've posted twice telling me again to run that exact same command either means you assumed I was blind and didn't see the output even though it was there, or maybe you skimmed over my original post instead of taking time to read everything and didn't notice I was using packet tracer. See NetworkVeteran's 2nd reply, there's the correct answer.

To be fair, I assumed you to be at fault because a google search provides the info you wanted. You asked how it was done, we told you.

I accept the fact you were too lazy to look at my screenshot and notice there's no such information shown. Don't worry about it

I did look at your screen shot, I did notice the lack of duplex information and I presumed it was a nuance of Packet tracer. Having never used it myself I could not tell. I fired up a Cisco 2651XM to test it for you and get you an accurate working command. If I'm guilty of anything it's not knowing packet tracer.
