I want to configure the client sub-mask to be 255.255.255.255 when allocating a DHCP IP address from a network with a mask of 255.255.255.128. This seems to be option 1, according to all docs, and the syntax should be quite simple "option 1 hex FF:FF:FF:FF". However, IOS hiccups, saying "DHCP, no raw value option 1". What is that all about? I don't know what "raw value" is or what the alternatives are. I've gone through every reference site that I can think of, and am still in the dark. Any clues as to how to achieve the goal?
Raw value is the value you have given after the "hex" word in the command for option 1. If you want to configure a raw DHCP option, you can figure out the right option format and configure the value correctly. For example if you want to give IP 10.144.21.06 then its hex will be 010a.90dd.06, where
thanks, that's what I thought I was doing with the hex pattern of all F's (I tried 'ffff.ffff' as well as the string shown).
