Hi team,

I have a problem, when I use ISE(version 2.2 patch 2) and 3850(version 16.3.3) to do 802.1x. After authorization my pc got the IP, but in 3850 I got IPv4 "Unknown", and I can not configure  "ip device-tracking"... Could someone help me.

Device tracking is the way the switch learns the IP.  Why can't you enable IP device tracking?

[lupingyao]

I tried with command "ip device-tracking":

3850SW2(config)#ip device?

% Unrecognized command

3850SW2(config)#ip device

I found myself:

int gi1/0/1

device-tracking
