We have a remote and host site connected via a frame relay cloud. The remote site is a new location and is running a newly purchased 1721 router.
The site runs good until a moderate load is placed on the circuit then it slows down significantly. This site is configured no differently than the 10 other sites attached to this frame cloud. Looking at the remotes interface stats show it's hardly being used in terms of load. The average ping response is 80 ms, but it jumps over 800ms during something as little as downloading an antivirus update from our Intranet server.
The remote site is running 12.4(1a), which I do see a bunch of bugs reported on the Cisco site. I plan on downgrading this router to the 12.3(??) release but wanted to see if anyone thinks this could be the problem.
I am seeing no errors on the interface and as mentioned above, the TX and RX load is well below 100/255.
Any thoughts on this?
