WPAD through Cisco DHCP

[msubtain]

How can i advertise WPAD entries through CISCO DHCP, i have done it in WINDOWS DHCP but not sure wether cisco DHCP supports it or not, can anyone please help?

Cisco DHCP is running on Catalyst 3560.

Thanks,

Muhammad

Hi there Muhammad,

Yes you can. You need to set the dhcp server to send out "option 252" with the address of your web proxy.

Hello again,

Can you confirm if the switch is sending out the dhcp option? A simple sniff should decide that. If it is sending it out, then you need to have a look if your syntax is correct. I've just had a quick look here http://www.microsoft.com/technet/prodtechnol/isa/2004/help/SRSP1_H_Create252.mspx?mfr=true and it says that the syntax should be "http://ipaddress:port/wpad.dat". If you've not put in the port option, then it will go to port 80, which the server may not be listening on.
