<div>
<p class=MsoNormal style='margin-bottom:12.0pt'><span style='font-size:10.5pt;
font-family:"-moz-fixed","serif"'> I want to log a few specific things
about DHCP assignments, and I've got most of what I want. <br>
<br>
log(info, concat( "RID", <br>
binary-to-ascii(16,8,":",option agent.remote-id), <br>
"-CID", <br>
binary-to-ascii(16,8,":",option agent.circuit-id), <br>
"-IP", <br>
binary-to-ascii(10,8,".",leased-address) <br>
) <br>
); <br>
<br>
To this I want to also add the IP address of the relay agent we got the initial
request from. I would want something similar to an "option
agent.relay-ip". Is there any such thing? Is there any other
way to log that? <br>
<br>
I do of course get "DHCPDISCOVER from <MAC> via <relay
agent>" lines, but I was hoping to get everything on one line. If
I can't then I can't, no biggie. <br>
