[cisco-voip] QoS VOIP with NM-ESW in ISR and QoS

[Jason Aarons (US)]

I did a sniffer trace and found calls from phones at a remote branch on
a NM-ESW-16 I don't receive DSCP markings, what is the proper config for
QoS for a 7940 phone on the NM-16ESW? I checked all hops in between for
mls qos trust dscp, etc

 

Phone > NM-16ESW >2811  ------------------------mpls wan
----------------------------3825>4507>Phone

 

ATL-2811 with NM-ESW phone is on 1/3 via show cdp neigh

interface FastEthernet1/13

 switchport mode trunk

 switchport voice vlan 31

 mls qos trust dscp

 spanning-tree portfast

end

ATL-2811(config-if)#int fa1/13

ATL-2811(config-if)#auto qos voip

%Error: FastEthernet1/13 Service Policy Configuration Failed.Only IN
