Question about Cisco Catalyst 3750G-24T SMI (WS-C3750G-24T-S) 24x1000 Mbps Networking Switch
Our network core is all Cisco 3750G-24T switches. They had no configuration, the original IOS (c3750-i9-mz.121.14-EA1a) and we just plugged them in and they worked. In the past few months, we've been having intermittent network issues. Half the building would have horrible latency or won't be able to access the network at all. Looking at bandwidth graphs shows you that not more than 10 megabits of our gigabit connection between switches is used. We've put passwords on the switches, reconfigured all links to ensure they are gigabit and to reduce hops between devices. We've also updated the IOS on one switch as a pilot and are running Cisco network assistant to visualize the network. We have yet to identify what was happening, or determine if it will happen again. What does your organization do to prevent this kind of problem? Thanks in advance for the advice!
I would be glad to help with this.
How many VLANs do you have? How many users per VLAN? Do you have a generic diagram (stripped of all company info) that you can share? Can you send me a "sh tech" from the core switch so I have a better feel for how things are configured?
