We recently started monitoring a customer that has some serious "buffer misses" issues. We use Solarwinds to monitor the routers, switches, and access points. I noticed a couple of switches a one of the locations had over 500,000 buffer misses in one day. I will attach a text file that shows the amount of buffer misses throughout the different devices on the network.
One thing to note - The IOS on the switches are the original ones that shipped with the switches and are about 6 years old. How much do IOS upgrades fix buffer misses, or do I just need to 'tune' the buffers? Also, I don't see any packet loss either. Most of the switches are 2900's with 8MB RAM.
Any suggestions would be appreciated.
