These are new switches, currently only about 10 ports are active as we have not migrated everyone accross yet. I have noticed that on all active interfaces there are alot of out drops being reccorded. All interfaces have a VoIP phone connected to the PC. QoS is enabled globally but there is no specifc QoS config on each interface. The switchports are all configured the same, as shown below: interface GigabitEthernet1/0/1 switchport access vlan 401 switchport mode access switchport voice vlan 301 switchport port-security maximum 2 switchport port-security switchport port-security aging time 2 switchport port-security aging type inactivity spanning-tree portfast spanning-tree bpduguard enable spanning-tree guard root These are the only errors showing up, there are no colisions, input or output errors, all interfaces are at 100Mb full duplex. Also, when i disable QoS globally (no mls qos) the output drops totally stop. Running IOS 122-53.SE1. Thoughs?
