<FONT face=Tahoma><B>From:</B> dhcp-users-bounce@isc.org [mailto:dhcp-users-bounce@isc.org] <B>On Behalf Of </B>Brendan Forsyth<BR><B>Sent:</B> Monday, October 20, 2008 2:57 PM<BR><B>To:</B> dhcp-users@isc.org<BR><B>Subject:</B> Option 43 for Cisco LWAP<BR></FONT><BR></DIV>
<DIV></DIV>
<DIV>Here is my problem. When I use the Cisco DHCP server and add option 43 for telling the access points about where the WiSM controller is, everything works fine. However from DHCP ISC v3.0.5, it doesn't. Here are the two configs:</DIV>
<DIV> </DIV>
<DIV>Cisco:</DIV>
<DIV>ip dhcp pool auto-pool<BR> network 172.17.112.0 255.255.255.0<BR> domain-name pvh.org<BR> option 43 hex f104.ac11.fe29<BR> option 60 ascii "Cisco AP c1200"<BR> default-router 172.17.112.1 <BR></DIV>
<DIV>A wire shark dump of the ACK shows this:</DIV>
<DIV>Option: (t=43, l=6) Vendor-Specific Information</DIV>
<DIV> Option: (43) Vendor-Specific Information</DIV>
<DIV> Length: 6</DIV>
<DIV> Value: F104AC11FE29</DIV>
<DIV> </DIV>
<DIV>The packet dump shows 2b 06 f1 04 ac 11 fe 29</DIV>
<DIV> </DIV>
<DIV>ISC DHCP</DIV>
<DIV> </DIV>
<DIV>option space Cisco_LWAPP_AP;<BR>option Cisco_LWAPP_AP.server-address code 43 = string;<BR></DIV>
<DIV> class "Cisco AP c1200" {<BR> match if option vendor-class-identifier = "Cisco AP c1200";<BR> option dhcp-parameter-request-list 43;<BR> option vendor-class-identifier "Cisco AP c1200";<BR> vendor-option-space Cisco_LWAPP_AP;<BR> option Cisco_LWAPP_AP.server-address f1:04:ac:11:fe:29;<BR> }<BR></DIV>
<DIV>
<DIV>Option: (t=43, l=8) Vendor-Specific Information</DIV>
<DIV> Option: (43) Vendor-Specific Information</DIV>
<DIV> Length: 8</DIV>
<DIV> Value: F104AC11FE29</DIV>
<DIV> </DIV>
<DIV>The packet dump shows 2b 08 2b 06 f1 04 ac 11 fe 29</DIV>
<DIV> </DIV>
<DIV>Note the two extra octets in the DHCP dump. Also the class definition was obtained from Cisco's site about configuring ISC DHCP for option 43 functionality.</DIV>
<DIV> </DIV>
<DIV>Any advice is appreciated.</DIV>
<DIV> </DIV>
<DIV>Thanks,</DIV>
