Cable is good. I am lost help is appreciated.

Is this a switch or a router. What's on the other end of the connection. How did you verify the cable is good. Are you using the right type of cable, crossover/straighthrough etc?

Is this a router or a switch? Routers could require a crossover cable to bring the int up.

This is a router and I am using a good crossover. Tested by use with another device.
05-04-2007 01:44 PM
Is it connected to a switch or a router. If it's a switch then you need to use a straight-through cable.
05-04-2007 01:58 PM
I assume the router interface is enabled (sorry ;-))? Can you do a hard loopback on both interfaces ?
05-04-2007 02:13 PM
I forgot to state that it is connecting to a pc. I issued the no shutdown command once the ip and subnet were assigned. I will do the lb and post results
05-04-2007 02:24 PM
I entered the command loopback and now

still down. If that was not what u meant by hard lb please let me know.

Try hard-seting the speed/duplex on the PC's NIC to 10/half... Many newer NICs will not come up if duplex between the network device and PC do not match.
10/100 Ethernet has no provisions in it for duplex negotiation.
05-07-2007 10:01 AM
I assume this is UTP ? We have UTP loopback plugs which loop the proper wires back onto themselves to make a "hard" loopback to see if the interfaces are OK. You can probably make one yourself provided you have the UTP pinouts...does the PC interface come up on a different port of the router did you say ?
05-04-2007 04:13 PM
There are two things that (normally) can cause this:
1) Try a new cable, in your case, probably a cross-over cable
2) An invalid ENCAPS type for Ethernet
Good Luck

Based on this in the output that you posted:
Hardware is Lance
I believe that this interface is 10 Mb half duplex. My guess is that the PC is not matching, probably because the PC is attempting to negotiate speed and duplex but the router interface does not negotiate. Try setting the PC to 10 half duplex and let us know what happens.

Kindly specify if this router is connected to any switch ,if connected with a switch ,you may use "SH IP INT BRIEF" on switch .Kindly update me on my mail id amit.kulshreshtha@yahoo.co.in. thanx

I appreciate the help. I will be checking the pc nic this after noon and all the other suggestions. I do appreciate all the help.
