Hi Darren,
Thank you for your answer.
What I actually need is to pretty-print the contents of what switch added the
option 82 into the logs. To be clear, here is an excerpt of what we have now in
our isc dhcp:
...
set SwitchName = "";
if ((exists agent.remote-id) and (substring (option agent.remote-id, 0, 1) =
0))
{ # Remote ID Type 0 means Mac Address
# Ethernetadress of FIRST Interface
set SwitchMac = concat (
suffix (concat ("0", binary-to-ascii (16, 8, "", substring (option
agent.remote-id, 2, 1))),2), ":",
suffix (concat ("0", binary-to-ascii (16, 8, "", substring (option
agent.remote-id, 3, 1))),2), ":",
suffix (concat ("0", binary-to-ascii (16, 8, "", substring (option
agent.remote-id, 4, 1))),2), ":",
suffix (concat ("0", binary-to-ascii (16, 8, "", substring (option
agent.remote-id, 5, 1))),2), ":",
suffix (concat ("0", binary-to-ascii (16, 8, "", substring (option
agent.remote-id, 6, 1))),2), ":",
suffix (concat ("0", binary-to-ascii (16, 8, "", substring (option
agent.remote-id, 7, 1))),2));
set SwitchName = SwitchMac;
}
if ((exists agent.remote-id) and (substring (option agent.remote-id, 0, 1) =
1))
{ # Remote ID Type 1 means ASCII String
set SwitchName_Length = extract-int (substring (option agent.remote-id,
1, 1),8);
set SwitchName = substring (option agent.remote-id, 2,
SwitchName_Length);
}
# Switch="switchname";
if (SwitchName = "") {set LogSwitchName = "";}
else {set LogSwitchName = concat (" Switch=\042", SwitchName, "\042;");}
set LogSlotPortVlan = "";
if ((exists agent.circuit-id) and (substring (option agent.circuit-id, 0, 1) =
0))
{ # Remote ID Type 0
set Vlan = binary-to-ascii(10,16,"", substring(option
agent.circuit-id,2,2));
set SwitchSlot = binary-to-ascii(10,8, "", substring(option
agent.circuit-id,4,1));
set SwitchPort = binary-to-ascii(10,8, "", substring(option
agent.circuit-id,5,1));
# SlotPort="n/nn"; Vlan="nnnn";
set LogSlotPortVlan = concat (" SlotPort=\042", SwitchSlot, "/", SwitchPort,
"\042;", " Vlan=\042", Vlan, "\042;");
}
...
So, my question is how to implement this in kea dhcp?
Kind regards,
Sinisa

Hi Wu,
Perhaps this article might help a little?
