DHCP manual binding

borek

I don't understand one thing on manual binding of IP addreses to MACs in DHCP pools. According to documentation one uses statement like this to specify MAC:

hardware-address 10aa.20bb.30cc

But as I figured, for this to work it actually has to be like following:

hardware-address 0110.aa20.bb30.cc

Nothing about prepending '01' to MAC is ever written in manual (same thing applies to 'client-id').

Can anyone explain this?

"01" represents the Ethernet media type.

My point is, that nowhere in IOS manual is written, that ethernet media type should be prepended to mac address.

BTW, I am preparing for CCIE lab and it isn't so unlikely that I will have to define static IP binding in DHCP... I really wonder what I am supposed to do: use configuration that is documented VERSUS use configuration that works.
