certain ports on switch not recognised by CER

[agup]

We have Cisco CER 9.0(2) and we have IP Phones connected to various switches. However, what we see that Gig ports /45 -  /48 are not discoverable in Switch port details in CER. We are using 3850 stack and the configuration on ports are identical, see below. We have reset the switch, reboot CER, but does not help.

Help!!!

I am seeing the same issue on 6 3850 switches CER cannot see Gi2/0/48 on some and Gi3/0/48 and Gi4/0/48 on others, the other stacked switches we CER sees all the ports We are also on CER 9.0.2.

I deleted the switch out of CER and rebuilt it and it did not change on the rediscovery.  I have opened a TAC case and will update when I find out more.

Cisco says bug CSCun37216 the switches need to be upgraded to 3.6.1E or later.

We are at 3.0.3

Hope this helps
