I have a Catalyst 6509 running IOS 12.2 that seems to be causing issues with some network applications. Such as Exchange, Excel spread sheets, some Intranet applications. The networks are Vlan'ed off, and it seems that most of the performance issues are on the Main Office Vlan.
I have setup SolarWinds Network performance monitor and found a few ports that were taking some input, CRC, and collision errors due to some speed/duplex configuration issues. Most of those errors have been cleared up, however application performance is still bad.
CPU has never exceeded 3%
Memory is always at 32.52MB
Availability is 100%
Packet Loss is 0%
Response time is from 181-114ms
All the buffers look are showing zeros except for the VeryBig Buffer that has shown 286 misses and 572 trims. The IPC buffer is showing 117 fallbacks and 3057 trims. However these maybe older numbers since the time stamps for the peaks are from weeks ago. I dont really see any loops on the network, ie no huge inputs, drops, or duplicate log errors.
I have been watching the performance monitor and logs for days and nothing else seems to be jumping out.
Thanks in advance.
