Cisco Layer 3 switch VLAN extremely slow
Hi There
I have a client who runs 2 x Layer 3 cisco switches with 3 VLANs configured.
VLAN120 Workstations
VLAN130 Servers
VLAN140 Voice
The Server and Voice VLAN speeds are fine, however the Workstation VLAN has slowed to a crawl. There have been no known config changes.
All workstations except 2 are switched off and they are working fine.
When we run a tracert to a server resource, the first hop is the switch and the second hop is the server
Any ideas or suggestions on where to look would be greatly appreciated.
Thanks
David

What does the delay on the traceroute show?

We're seeing less than 1ms for each hop

We're seeing less than 1ms for each hopThat doesn't sound slow at all.
It would help if you described the symptom.

Hi Mike
It's all workstations that slow to a crawl, doesn't matter what resource they area trying to access internet or server.
I'm firing up wireshark, if it's broadcasts we might not see them as most of the workstations have been turned off.
Thanks

Hi Don
I can only provide you with the latency right now without the workstations switched on. All users have gone home due to the usability (the site is also remote so I can only work with 2 workstations)
Thanks

So is it slow with only the 2 workstations?
You have to understand, "the network is slow" may be the most common, and often miscategorized, problem in the world of tech.

Without some type of metric for defining performance, there's really not much to go on other than the traceroute response times. Which are normal.
could you please run
ip accounting on vlan 120 and see where you see more traffic with which IP?

Since you've awarded points, can you explain for future generations what solved the problem?
