Hi, I just need someone input recommandation. It seems to be ghost service slowing down the whole vlan on the segment while ghosting image for about 10 PCs at a time. is it always true Ghost has big impact of network connection? Do you think I should create a new VLAN on cisco switch 3750 dedicated for ghost service? or any other idea?

10 pcs at the same time, at what about 100gig per pc? What is your bandwidth? 100/1000mb? Vlans have no effect on throughput in this regard. They are just hardwarded in the switch gates. Creating another vlan won't address bandwidth. Imagine the power of knowing how to internet search http://www.lib.berkeley.edu/Teachin...

How are you deciding it is the switch? CNA or telnet to show commands? "Best Practices", Event viewer, host file, perfmon, are in my top 10

I am not too concern about the thru-put of ghosting image for PCs. ALl I just dont want to affect other vlans while using ghost service. becasue I received a lot of complaint from users about network performance significantly slow when ghost service start, after ghosting finish, network was back to normal. so I am not sure create dedicated vlan will help, if not, what is your solution suggest? and if anyone familiar cisco switch CLI, what command I should issue to aviod this type of problem, or feature from cisco I need to enable? thanks!

My post wasn't asking you to be concerned about the throughput of your ghosting. It was to determine how much bandwidth you were using. Why do you think your ghosting effected everyones performance? A vlan shares the static amount of bandwidth available with other vlans which is why you received complaints. Your ghosting vlan saturated the network and effected everyone on the switch no matter what vlan they were in. Your only solution is don't ghost as many machines at the same time or schedule it during nonworking hours. Imagine the power of knowing how to internet search http://www.lib.berkeley.edu/Teachin...

If you think it is the load on the switch (anything over about 60-70% rated bandwidth) then the switch statistics will show that. You can address that by limiting other protocols that are not as much needed. For most situations a switch is a vlan. To be more precise it is a single collision domain. Might be easier to get Cisco's CNA to do this. http://www.petri.co.il/csc_cisco_ne... "Best Practices", Event viewer, host file, perfmon, are in my top 10
