[c-nsp] Possible interface counter bug, but wanted to check..

[Drew Weaver]

Hi,

We have a Gig-E connection going from a GSR to a 6500 and the 6500 appears to be showing almost double the amount of traffic/packets per second than the GSR is showing in its interface counters (for the same connection)

GSR: 

30 second input rate 326816000 bits/sec, 233144 packets/sec
30 second output rate 172271000 bits/sec, 223016 packets/sec

6500/Sup720:

30 second input rate 381479000 bits/sec, 479251 packets/sec
30 second output rate 708996000 bits/sec, 497164 packets/sec

Has anyone seen this before and know what the issue could be?

The 6500 is running:  12.2(18)SXD7b

I'm more inclined to believe the stats coming from the GSR, but I wanted to check with you folks and see if anyone has any experience with this particular errata.
