[c-nsp] Really need help with atm vc-per-vp on NM-4T1 3640

[Ruben Alvarez]

Hi Jason.

That sounds like the bug:

"When configuring ATM-IMA, if the vc-per-vp value is set to 1024 (or value
other than 256) and the config is saved in NVRAM, the value of vc-per-vp is
not reflected after reload. After reload, the vc-per-vp value goes back to
256.
This issue has also been seen to surface after an interface shutdown and no 
shutdown, irrespective of a reload.
There is no workaround but to upgrade to a version of IOS with the fix for
this issue."

First fixed-in version: 12.2(2.4), 12.2(2.4)T, 12.2(3.3)S, 12.2(3.4)B,
12.2(15)ZN

On my 3640, I have to re-enter the command at each boot for the 
interfaces because it won't save in the startup config.

dsl-atm.a10.dc(config)#int atm1/0
dsl-atm.a10.dc(config-if)#atm vc-per-vp 1024
dsl-atm.a10.dc(config-if)#^Z
dsl-atm.a10.dc(config)#int atm1/1
dsl-atm.a10.dc(config-if)#atm vc-per-vp 1024
dsl-atm.a10.dc(config-if)#^Z

Then I have to reenter customer's configs. 12.1(5)T15 is what I am 
running.
