9300 Auto QoS

[uppermost]

What is the difference between if I configure port with

auto qos voip cisco-phone

and

auto qos trust cos

I am trying to replicate interface configuration from old (3850) to the new switch (9300)

interface GigabitEthernet1/0/45
switchport access vlan 414
switchport mode access
switchport voice vlan 514
switchport port-security maximum 2
switchport port-security violation restrict
switchport port-security aging time 2
switchport port-security aging type inactivity
switchport port-security
srr-queue bandwidth share 1 30 35 5
priority-queue out
mls qos trust device cisco-phone
mls qos trust cos
macro description cisco-phone
auto qos voip cisco-phone
spanning-tree portfast edge
spanning-tree bpduguard enable
service-policy input AUTOQOS-SRND4-CISCOPHONE-POLICY

On the new 9300 I can configure either auto qos trust cos or auto qos voip cisco-phone but not both as it is on the old switch.

Hi

 They overlap most configuration. Only the highlighted will be additional if you use cisco-phone. I would recommend use cisco-phone if that is the case for this port.

auto qos voip cisco-phone

The following is an example of the auto qos voip cisco-phone command and the applied policies and class maps.
