IS-IT--Management
Description of the issue:
My company experiences network slowness, (3000ms+ ping times). It typically happens on only Monday mornings between 8am and 11am(times are not exact). But in the last 2 weeks it seems to happen other days, even as I type this, we are experiencing 1000ms+ ping times. We have 2 bonded T1s coming into the building which connects to a Cisco 2800 router and that connects to a SonicWall firewall. I have had SonicWall look at the FW config and logs multiple times but nothing looks "odd". We have had our ISP remote into the 2800 router, during the slowness, and ping out with normal responses (~30ms) and showing we are only using about 25% of our bandwidth. I have connected directly to the lan port on the FW and I receive normal responses but within 3-5 minutes of plugging the core switch back in, the slowness reappears. The issues first appeared somewhere around the time when we replaced all of our switches, which was about 3 months ago.
What we are looking for:
Basically, we are looking for some way of being able to monitor our network traffic during this period of slowness to determine what is causing the issue.
If you need more detail to be able to help, let us know and we will get it!
Any ideas or thoughts will be appreciated.
Thank you in advance for your help!
