Hi, Excellent method & thanks for publishing.
option 60 VCI values are practically used for Lightweight Wireless Access Points to find the WLC. Cisco has published option 60 ascii strings for all access points. (it's something like "Cisco AP c1240"). Nowhere I could find ascii string for 7965 phones. Decoding your hex value gives ascii string "Cisco Systems, Inc. IP Phone CP-7960?" BTW , CCIE lab has all 7965 phones as mentioned in cisco website. Thanks On Mon, Nov 21, 2011 at 4:44 PM, Mohammed Al Baqari < baqari.voic...@gmail.com> wrote: > Regarding DHCP it can be done.
