ATM problem

[Bekirk999]

Hi everybody,

I have a problem with my Cisco 3745 routers. I have in each of them a card with ATM port as on the following link:  http://www.google.fr/imgres?q=carte+port+ATM+cisco&hl=fr&biw=1280&bih=861&tbm=isch&tbnid=_jV5TvF0NvNB_M:&imgrefurl=http://www.newerasystems.net/vsat-equipment-sale-manufacturer.html&docid=nE9GF87XjRaYmM&imgurl=http://www.newerasystems.net/inven-pics/...

I need to test if the ports work, however no way to use the ping atm interface <interface_atm>  command and whatever the IOS installed. Originally I was 12.3, I tested in 12.4 and it does not work either ... The command does not appear on the routers ...

An idea ?

Thanks

You can put a physical fiber loop on the port or you can put a software loop on the port.

I don't know what you want to say. Can you explain with more details please?
