MGX-8850 ( Command???)

Unanswered Question

Hello,

I am just wondering if someone has seen the following command on the Cisco MGX. I can't seem to find any information on google or cisco. This command doesn't look complete to me. But any ideas, if someone has seen the following command or if it's missing what's the COMPLETE one is.


Will apprecaite it...


" ping atm sw "


Is there anything else after sw or any ideas.


Regards,

Hassan..

There is no such direct command called ping atm sw . Waht are you trying tp ping . Trying to ping the ATM switch. Normally VP I/VCI of the ATM is pinged.

Hello,

I have found the right command. But trying to find out the details. I am searching cisco pages and google right now to get my concept clear. Following is what i am talking about.


Router# 1#ping atm switch 1.2101 1 2101 ?

end-loopback Send End to End Loopback

seg-loopback Send segment loopback


What is this end-loopback and seg-loopback. Does end-loopback means it's pinging the loopback of CE on the other side. So i am confuse and searching for a document for clear understanding.


Thanks,

Hassan

End-to-End is an ATM OAM cell sent to the ATM interface of the far-side device...for instance:


MGX -- ATM-switch -- GSR


The end-to-end would be sending the OAM to the subinterface/VC on the ATM interface on the GSR. The segment loopback is VC-based verification between the MGX and the connected ATM-switch. Many applications connect the MGX directly into the router so the end-to-end and segment loopback may, in your case, be the same.


Hope that makes sense.
