Option 82 logging on dhcpd 4.1.1 and red hat 6

[Alex Moen]

Just comparing with mine, it seems that the "option agent.circuit-id" 
needs to be in parens.  And, I don't know the use of the 
"(leased-address)" is.  So, try this:

-----------------------------------------------------
## Option 82 Class
class "myvendor" {
match if option agent.circuit-id = 00:04:00:6b:00:84;
}

# Test Option 82 logging
if exists agent.circuit-id
{
log (info, concat(
     "Lease for ", binary-to-ascii (10, 8, ".", leased-address),
     " with circuit-id ", (option agent.circuit-id),
     " is assigned using Option82"
     ));
}

pool {
                 allow members of "myvendor";
                 range x.x.x.x x.x.x.x;
         }
-----------------------------------------------------

This should give you a line that looks something like:

Lease for 192.168.0.10 with circuit-id Ethernet 5 is assigned using Option82

Obviously, your circuit-id will most likely be something other than 
"Ethernet 5", but you get the idea.

If I'm way off base, someone please correct me!

Good luck,

Alex
