Hello,
I have a Cisco 2811 that seems to having a buffer leak. I have a 100mbps cable connection for the WAN. I'm also running the latest code.. when ever i look up how to fix this leak cisco tells me to upgrade to the latest code so that fix is out..
On the show int fa0/0 and fa0/1 notice the throttles and other buffer related issues.. I rebooted the router yesterday so the counts are low.
If anyone has any feed back or recommendations let me know.. Thanks!!!
