Ghost casting

[vallan]

why is my GhostCasting s slow when i use it over the switch ( Cisco 6509) as against when i do it via crossover cable or othe devices.

I want to be able to use the Cisco Switch but it give me throughput of 5mb/min so takes over 2 hrs whereas directly gives me 280mb/min and takes just minutes.

Any ideas

Multicast, Unicast, or Broadcast??

What Ghost way are you doing it?

Sounds like a Autosense problem on the pc/switch, try setting the ports on 100/full and the pc and try again.

ither unicast ot multicast. I have set it to 100/Full both on the Switch and on the port where the client is connected to.

It is still very slow.

Check those ports for errors and see if anything funky is going on..

I have the same problem. Deploying 10 Pcs on the Cisco 2950 switch is very slow. Can someone find a solution for this. Thanks

the best way is to set ghost up for multicasting, then make sure you have fast switching turned on your cisco switch, your problem comes from the fact that every packet that comes is the switch CPU is haveing to build the table to send it, with fast switching it builds it once then remembers the table. if you try watching your cpu on the switch it's probably at like 90-100%.

I am having a similar problem to Vallan.

After reading up on fast switching I get the impression that it is more a router feature. If it is a configuration option for Cisco switches, (Catalyst 2950), what are the commands for this.

Cheers.

I would check out the port statistics like BuckWeet suggested. Do a "show interface" on all the computers and see if your getting any send or receive errors.

Ok. I have resolved this issue.
Set your Cisco Swith to Auto Negotiate on each ports and upgrade your Ghost 7.5 to Ghost 8.0. You will find out all ghost imaging will run smoothly.

Folks,

I am having a strange thing happen when I am trying to ghost across the WAN. Multicasting wasn't working for me, so I made a drive mapping boot disk. Upon booting, the machine receives a DHCP address no bother. It then authenticates me to the domain, but it will not map the drive. I have tried mapping the drive using IP address rather than machine name, but that didn't work either. Strangely enough, if I try to map a drive to the sysvol share on the DC that authenticated me to the network, I am successful, even when using machine name. If I try to map a drive to the sysvol share on another DC, it will not work. Does anyone have any idea what is wrong and what I would have to do to correct the problem. My WAN is totally switched, no routers. If I use the same disk on the same LAN as the ghost server, it works straight away.

Many Thanks,
