I have several new 2960-X stacks, and I'd like to get a proper Qos configuration on them. These stacks uplink to 2 Nexus 5548s.
So far my interface commands look like this...
interface GigabitEthernet1/0/4
switchport access vlan 30
switchport mode access
switchport voice vlan 60
srr-queue bandwidth share 1 30 35 5
priority-queue out
mls qos trust device cisco-phone
mls qos trust dscp
auto qos voip cisco-phone
spanning-tree portfast
spanning-tree bpduguard enable
service-policy input AUTOQOS-SRND4-CISCOPHONE-POLICY
Enabling auto qos added a bunch of mls qos commands on the switch. So my questions are ...
1. What is the difference of having just the "mls qos trust device cisco-phone" and "mls qos trust dscp" commands on the interfaces, as opposed to also having "auto qos voip cisco-phone" ?
2. What command should be added to the uplinks?
3. Do the 5Ks have auto-qos enabled out of the box, or should enable it on the physical interfaces connected to the 2960 stacks?
