I have no dhclient running. I need to have this information available on
the dhcp server handing out the prefix.

Hello DHCP experts! We are implementing Option 82 in our network and I am
just scratching the surface of how to setup my server. I have successfully
created my first Option 82 ACL based on the agent circuit ID that is
contained in the packet, now I just need guidance on how I get the Option
82 data into the logs. Here is my O82 setup on the server:
## 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 ", option agent.circuit-id (leased-address),
"is an address assigned using Option82"));
}
pool {
allow members of "myvendor";
range x.x.x.x x.x.x.x;
}
The problem I am having is when I go to check the conf before restarting
dhcpd I am getting the error:
etc/dhcp/dhcpd.conf line 135: right parenthesis expected.
log (info, concat( "Lease for ", option agent.circuit-id (
^
Can anyone tell me what I am doing wrong and how to fix this error?

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

Alfred - thanks but your setup is much more complex than mine.
Alex, I have put in the changes as you suggested and it passed validation.
I'll report back what the logs look like or if I have any further problems.
Thanks!

Hmmm.. OK here is the log for the test client.
Oct 4 11:39:20 dhcpd: Lease for X.X.X.X with circuit-id
That's all it said.
I know that my ACL class for circuit id works as it was allowed to get an
IP address.
The log line reported back the correct IP so I know that the
"Lease for ", binary-to-ascii (10, 8, ".", leased-address),
Line in my logging clause works.
But why did it stop there? Do I need to remove the parethesis around
"option agent.circuit-id" since I am not using parenthesis in my ACL class?
