Hi,
Dhcp-class-Identifier value comes as empty when we get the value from third party code bacbase, and found that TCPdump itself doesnot show the value for "Vendor class identifier" in DHCP Discover/Request packet.
The value comes below when it got selected from pcap file.
"00:00:36:3d:74:01:07:50:6f:6c:79:63:6f:6d:02:18:53:6f:75:6e:64:53:74:61:74:69:6f:6e:49:50:2d:53:53:49:50:5f:36:30:30:30:03:10:33:31:31:31:2d:31:35:36:30:30:2d:30:30:31:2c:42:04:1e:53:49:50:2f:34:2e:30:2e:38:2e:31:36:30:38:2f:30:37:2d:46:65:62:2d:31:35:20:31:30:3a:33:39:05:1d:55:50:2f:35:2e:30:2e:38:2e:30:39:33:35:2f:31:34:2d:4a:61:6e:2d:31:35:20:32:30:3a:31:37"
Please refer attched snapshot. is there any problem for this attribute to populate on polycom?
This DHCP value for the device used in Cisco product ISE.
