Hi Duke, It should work the way you have it configured. Though if you are using voice-vlan, you really don’t need to set up the CoS separately because it does that as part of the voice-vlan. Page 893 [URL] But it isn’t hurting anything to have it like that. For your second question you are correct and since it is in general mode the access mode commands don’t do anything.
I am working on setting up a new stack of two Dell N2048P switches and I'm stumbling through the Voice QoS part of the setup.  A colleague started setting up this config and I am trying to get ready for production. Any help or advice would be greatly appreciated.  configurevlan 20,22-26,28-29,253exitvlan 20name "Workstations"exitvlan 24name "Voice" system jumbo mtu 9216no ip http serverip http secure-serverboot auto-copy-swclass-map match-all voice-mapmatch vlan 24exitpolicy-map voice-policy inclass voice-mapassign-queue 2mark cos 5 switchport voice vlanip ssh serverapplication install SupportAssist auto-restart start-on-bootapplication install hiveagent start-on-boot interface Gi1/0/1cos-queue strict 5description "Workstations"classofservice dot1p-mapping 5 5switchport mode generalswitchport general pvid 20switchport general allowed vlan add 24 taggedswitchport access vlan 20lldp tlv-select system-description system-capabilities management-addressswitchport voice vlan dot1p 5switchport voice vlan override-authenticationexit!interface Gi1/0/2cos-queue strict 5description "Workstations"classofservice dot1p-mapping 5 5switchport mode generalswitchport general pvid 20switchport general allowed vlan add 24 taggedswitchport access vlan 20lldp tlv-select system-description system-capabilities management-addressswitchport voice vlan dot1p 5switchport voice vlan override-authenticationexit!
