Hi Philip,
In case this issue may occur again, the 3650 switch had an issue with one of it's ASICs that has been documented for the C3850-48P switch. Unfortunately there was no work around for the C3650-48P except having Cisco replace the switch via RMA. Upgrading the IOS to the recommended version or latest version did not fix the problem. Below are the detailed symptoms from Cisco:
Traffic not forwarding on access ports on one ASIC, while Mac&ARPareLearn
CSCux39091
Description
Symptom:
A WS-C3850-48P may not forward packets out of the ports associated with either forwarding ASIC 1 (port 1-24) or forwarding ASIC 0 (ports 25-48). During the packet loss the EGR_MISC_FATAL_ERROR counter increments in the "show controllers ethernet-controller port-asic statistics exceptions switch {switch#}” command output for the effected ASIC
Conditions:
The issue can be seen if the switch is doing L3 or L2 forwarding. MAC and ARP table entries are complete
The issue has been seen until now on a WS-C3850-48P running 3.3.5 and 3.3.0
Workaround:
The issue was resolved after an upgrade to 3.6.3. It is unclear at this point whether the code upgrade or the switch reload fixed the issue
