Hello I have a cisco ASR 1002 I have plugged a host into an addressed port and the port comes up however the host cannot ping the router and the router cannot ping the host. Neither can router ping its self. I do the same on a cisco 2800 router and it works fine. What's goin on. Is it the fact that this is a ASR router ?

Can you share the config (remembering to minimise passwords). I presume there aren't any ACL? If it is a L3 port, have you tried using a crossover cable? Does the interface show as UP?

I hope this is a silly issue that is just down to it being a ASR router,

You are right, it will probably be something obvious. I can't see anything immediately wrong. You could try forcing speed and duplex settings. I had a similar problem when I used a non-Cisco RJ45 SFP. But you say you are using Cisco. Maybe swap that and the cable if you have spare.
Sorry I can't be more helpful
05-14-2013 01:06 AM
Yer, its really doing my head in.
The SFP & cable has been changed, but still no luck.
I have never touched an ASR before, but i cannot see them differing that much from a normal Cisco router.
anyone ? any help ?
05-14-2013 07:08 AM
If you unplug the cable does interface Gig0/0/0 change state?
This part of the output of show interface seems to indicate that it recognizes that it has a copper sfp and negotiation seems normal
Full Duplex, 100Mbps, link type is auto, media type is T
Does the output of show arp show any MAC for the PC? I would suggest trying debug arp and attempt ping (be sure that logging monitor is enabled and set to level debug if you use term mon, or make sure that logging buffered is enabled and set to level debug if you use show log). At a minimum it would verify whether the ASR is seeing anything coming from the PC.
