[cisco-bba] "ppp timeout idle" & 10K

[Tassos Chatzithomaoglou]

We moved from 7200 (12.3(12b)) to 10K (12.3(7)XI6) (both used as LNS) and we have come into a 
serious "bug".

"ppp timeout idle" isn't working correctly when used under virtual-template. All sessions are 
terminated using ppp idle timeout as the reason, regardless of their traffic. Like the idle timer is 
never being reset.

Although that particular interface has interesing traffic passing through all the time, the timer 
isn't reseting.

10000#sh caller time
   Line           User               Limit     Remaining Timer Type

   Vi2            test at test.gr \
                                     01:00:00  00:52:49  PPP idle
...
10000#sh caller time
   Line           User               Limit     Remaining Timer Type

   Vi2            test at test.gr \
                                     01:00:00  00:41:58  PPP idle
...
10000#sh caller time
   Line           User               Limit     Remaining Timer Type

   Vi2            test at test.gr \
                                     01:00:00  00:21:12  PPP idle

Also another (cosmetic) bug is that the output rate of virtual access interfaces is displaying 
incorrect values.

Here are some examples when in/out traffic should be ~1000/1000 bits/sec.

Virtual-Access2 is up, line protocol is up
   30 second input rate 1000 bits/sec, 1 packets/sec
   30 second output rate 509032000 bits/sec, 1 packets/sec

Virtual-Access2 is up, line protocol is up
   30 second input rate 0 bits/sec, 0 packets/sec
   30 second output rate 2631000 bits/sec, 329021 packets/sec

Virtual-Access2 is up, line protocol is up
   30 second input rate 0 bits/sec, 0 packets/sec
   30 second output rate 1144204000 bits/sec, 143025765 packets/sec


Can anyone help me identify these bugs? When i searched on CCO i found some similar bugs but none of 
them applied to our ios version.
