Use the "option 150 ip " command for specifying th e TFTP server.

have a look at this link

Hi,

TFTP is DHCP option number 66, thus you need to add the following line under the DHCP pool;

option 66 ascii

[edit] I guess Narayan is correct, define option 150 if the TFTP server does not have an entry in the DNS server.

HTH,

Mohammed,

It would depend upon what the user is trying to do with the tftp server.

I think if the user is concerned with returning the TFTP server address for DHCP clients such as IP phones we generally use option 150

Hi Narayan,

First of all, sorry for replying on your reply :) but as i told you before i am using a slowww dial-up link these couple of days, any way using option 66 needs a DNS entry for the TFTP server, and thus i agree with you that using option 150 is the most optimum method.
