I implemented rate-limit using 2611, but when i see the interface statistic i saw so many packet error, CRC, and Collision. Which cause the network become unstable and so slow, i have to clear ip nat translation, logging, and dhcp binding and even to reload the router first to make it works normal again. But after a while it happened again. All my switches using catalyst 2924. If i use 2611 just for simple routing without rate-limit, no packet error, crc, or collision.
Any idea what was wrong with the router? I used IOS 12.3(5a). Thanks before.
