Catalyst 3650 QoS implementation

[pdub206]

When developing an AutoQoS strategy for a branch office, are the below settings correct? Let's say that there is a mixture of Cisco hard phones and Jabber soft phones in the environment.

Access ports:

auto qos voip cisco-phone

Trunk ports:
auto qos voip trust

Egress port to firewalls:

auto qos voip trust

From the firewall, the data is passed over an ipsec tunnel to another site where the actual voice environment is located (and a different Cisco platform to deal with on another day).  Basically, the idea is to give voice traffic preferential treatment over say, a file transfer, when it is on its way to the firewall.

yes that setup should work fine , I have same type of setup in some offices with auto qos , just confirm packets are being marked correctly with wireshark or through the policy maps that are generated , so your aware ios-xe trusts dscp by default to so if the phone marks as EF 46 switch will honor and carry it without interaction

To see this use

cc#sh platform qos dscp-cos counters gigabitEthernet 1/1/1 | i DSCP46
Ingress DSCP46 410631304     0
Egress DSCP46 206695944     0
