I have ATA 187's and 190's, some with most recent firmware some with older firmware that were working fine on older switches. Hardware upgrade to CAT9k running 16.9.4. After the upgrade random ATAs will not pull an IP address unless I strip the config completely off the port and even then it will do DHCP but won't register to CM. I am posting the port config. Exact same config is on port of ones that are working as ones that are not. Anyone seen this? I am thinking undocumented bug.
Thanks in advance!
