Hello,
Our 2811 WAN router is experiencing a high volume for huge buffer misses with some failures. Should we look into the automatic buffer tuning command as our IOS supports it. Does the router need to be reloaded after? Has anyone exeprienced any issues with this command or having traffic dropped (even bliped)? Any suggestions?
