[c-nsp] Re: No "ping atm" command in 12.2-xx.Sxx

[james edwards]

Yep, however, c7200-k91p-mz.122-25.S6.bin (SSH/3DES) does have ATM OAM ping,
but not 12.2-18S w/SSH,3DES.. Go figure. 12.2T had it. I opened a TAC case
and could not get any guaranties/explanation that this feature would remain
in the 12.2S SSH/3DES IOS. Even though it is in 12.2T and 13.3T and 12.0.  I
only run 7206's and was hoping to move all of them to 12.2S, 13.3T is
overkill just to pick up one or two basic features; the latest 12.2T has ACL
bugs. I looked at the pvc-range command and decided to pass on it for now.

12.2-25S is a bit too new for me so I was hoping to get this feature added
to 12.2-18S & TAC could offer no help with this other than suggest to down
grade to 12.0. 12.0 is not suitable for my DSL agg needs.

I work with 3 LEC's as the ISP for DSL. None of them can correctly cross
connect a DSL PVC between me and the customer
with any consistency. A quick OAM ping the seg-loopback and I can quickly
prove the cross connect is wrong.
Without ATM OAM pings we play "no it is not my network, it is your network"
for a week. This is just one example of how I use
this very basic feature every day.
