It has been a long time since I have done this, and I am just looking for confirmation. 
 
Below is a snippet of a configuration from a 2960 Cisco Catalyst switch. 
 
Will the configuration below for port 36 actually provide QoS when an IP phone is plugged into it? 
 
interface FastEthernet0/35 
&nbsp;description Standard port configuration 
&nbsp;spanning-tree portfast 
! 
interface FastEthernet0/36 
&nbsp;description LAN port to support PC or VoIP config 
&nbsp;priority-queue out 
&nbsp;mls qos trust cos 
&nbsp;spanning-tree portfast 
&nbsp;spanning-tree bpduguard enable 
 
&nbsp;interface Vlan1 
&nbsp;ip address 172.21.2.3 255.255.0.0 
&nbsp;no ip route-cache 
! 
ip default-gateway 172.21.1.10 
 
What I KNOW works is that when you plug a PC or a VoIP phone in, both work on the VLAN1 as defined. &nbsp;But I do not know if QoS is working when an IP phone is plugged in. 
 
thank you, 
Jeff

A personal computer is a general-purpose computer whose size, capabilities and price make it useful for individuals, and is intended to be operated directly by an end-user with no intervening computer time-sharing models that allowed systems to be used by many people, usually at the same time. Personal computers may be connected to a local area network (LAN), either by a cable or a wireless connection, and through that to the Internet. A personal computer may be a laptop computer or a desktop computer running an operating system such as Windows, Linux or Macintosh OS.

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).
