Page 40: Intervlan Routing
The forwarding performance for interVLAN routing on the Catalyst 4224 is 35 Kpps for 64-byte packets. Fast Switching is the default switching path. The Catalyst 4224 supports Cisco Express Forwarding (CEF). Quality of Service The Catalyst 4224 can function as a Layer 2 switch connected to a Layer 3 router.
Page 41: Separate Voice And Data Vlans
You cannot configure port-based QoS on the Layer 2 switch ports. Separate Voice and Data VLANs To be consistent with Cisco IP Telephony QoS design recommendations, you should configure separate voice and data VLANs. The following sample configuration shows how to configure separate voice and data VLANs.
Page 42: Layer 3 Qos
IP phone is attached to the port via the CDP message exchange. Layer 3 QoS You can configure QoS on the Layer 3 CPU from the CLI, which is very similar to the interface on the Cisco 1750, Cisco 2600 series, and Cisco 3600 series routers. WAN QoS Queuing and Scheduling The Catalyst 4224 supports WAN QoS queuing and scheduling.

If you require an additional VLAN beyond the voice and data VLAN when connecting to another switch, you must add it manually using the VLAN database command from the EXEC prompt.
Page 50: Trunking
Chapter 1 Product Overview Recommended Configurations Trunking The Catalyst 4224 supports only dot1Q trunking. Dynamic Trunking Protocol (DTP) is not supported. A Catalyst switch that is trunked to the Catalyst 4224 must have the trunking mode set to either On or No negotiate and type dot1q. Fractional PRI Configuration The maximum of 16 channels are available for trunk voice ports.
Page 51: No Ring Back Tone Generated
Progress IE in the setup. (Progress IE = 0.) The Catalyst 4224 does not generate ringback when it receives an alert from Cisco CallManager. You can avoid this situation and force the Catalyst 4224 to generate a ringback using the progress indicator commands on the VoIP and POTS dial-peer statements.
Page 52: Mtp Required On Cisco Callmanager
This checkbox is located in the Catalyst 4224 H.323 Gateway Configuration page in Cisco CallManager to define an H.323 gateway. All Cisco IOS H.323 gateways with Cisco IOS 12.07 or later now support H.323 Version 2. You should not ordinarily enable this checkbox box when defining the Catalyst 4224 as an H.323 Gateway.

IP address. By default, the Fast Ethernet interface does not route data traffic. Caution Cisco recommends that you do not override this default configuration. If the Ethernet 10/100 management port is up and an IP address has been configured, the Catalyst 4224 selects the IP address assigned to the 10/100 Ethernet management port.
Page 60: Interface Numbering
Chapter 2 Configuring for the First Time First-Time Configuration If the selected network management IP address is removed or the interface or subinterface associated with this IP address is shut down, the Catalyst 4224 selects another IP address as a replacement. If all the interfaces are down or no IP address has been assigned to any interface or subinterface that is running, the IP address for network management is 0.0.0.0.
Page 61: Using The Cisco Ios Cli
Cisco voice gateways straightforward because you will use the Cisco IOS CLI, with which you are familiar. If you have never used the Cisco IOS CLI, you should still be able to perform the configuration required using the instructions and examples provided in this guide.
Page 62: Getting Help
You can continue to press the Up Arrow key for more commands. Command Modes The Cisco IOS interface is divided into different modes.

The Cisco IP SoftPhone application was developed to provide clients with a phone that runs on software.
Page 68: Configuring Separate Voice And Data Subnets
Configuring Separate Voice and Data Subnets For ease of network administration and increased scalability, network managers can configure the Catalyst 4224 to support Cisco IP phones such that the voice and data traffic reside on separate subnets. You should always use separate VLANs when you are able to segment the existing IP address space of your branch office.

IP phone. This is done to obtain its IP address as well as the address of the TFTP server required for its configuration. Be aware that Cisco IOS supports a DHCP server function. If this function is used, the Catalyst 4224 serves as a local DHCP server and a helper address would not be required.
Page 71: Configuring A Single Subnet For Voice And Data
Layer 3 classification is already handled because the phone sets the type of service (ToS) bits in all media streams to an IP Precedence value of 5. (With Cisco CallManager Release 3.0(5), this marking changed to a Differentiated Services Code Point [DSCP] value of EF.) However, to ensure that there is Layer 2 classification for admission to the multiple queues in the branch office switches, the phone must also use the User Priority bits in the Layer 2 802.1p...

Page 77: Removing An Ip Address
Specifying a Domain Name and Configuring the DNS Each unique IP address can have an associated host name. Cisco IOS software maintains a cache of host name-to-address mappings for use by the EXEC mode commands connect, telnet, ping, and related Telnet support operations. This cache speeds the process of converting names to addresses.
Page 78: Configuring Voice Ports
Domain names are pieced together with periods (.) as the delimiting characters. For example, Cisco Systems is a commercial organization that IP identifies by a com domain name, so its domain name is cisco.com. A specific device in this domain, such as the File Transfer Protocol (FTP) system, is identified as ftp.cisco.com.
Page 79: Configuring A Port To Connect To A Cisco 7960 Ip Phone
Because a Cisco 7960 IP Phone also supports connection to a PC or other device, a port connecting a Catalyst 4224 to a Cisco 7960 IP Phone can carry a mix of traffic. There are three ways to configure a port connected to a Cisco 7960 IP Phone: All traffic is transmitted according to the default CoS priority (0) of the port.
Page 80: Enabling And Disabling Switch Port Analyzer
A detection mechanism on the Catalyst 4224 determines whether it is connected to a Cisco 7960 IP Phone. If the switch senses that there is no power on the circuit, the switch supplies the power. If there is power on the circuit, the switch does not supply it.

Page 82: Managing The Mac Address Tables
Chapter 3 Configuring Ethernet Switching Managing the Catalyst 4224 Access Gateway Switch The Address Resolution Protocol (ARP) associates a host IP address with corresponding media or MAC addresses and VLAN ID. Taking an IP address as input, ARP determines the associated MAC address. Once a MAC address is determined, the IP-MAC address association is stored in an ARP cache for rapid retrieval.
Page 83: Mac Addresses And Vlans
Chapter 3 Configuring Ethernet Switching Managing the Catalyst 4224 Access Gateway Switch Figure 3-3 Contents of the Address Table MAC Addresses and VLANs All MAC addresses are associated with one or more VLANs. An address can exist in more than one VLAN and have different destinations in each. Multicast addresses, for example, could be forwarded to port 1 in VLAN 1 and ports 9, 10, and 11 in VLAN 5.

Page 131: Fxo Emulation Example
To use FXO emulation to connect the T1-CAS port to the PSTN, you must have Direct Inward Dialing (DID) enabled on incoming DS-0 groups. DID allows the gateway or Cisco CallManager to identify the extension to which each call on an incoming DS-0 group is directed. Because DID only works on incoming connections, you must have separate DS-0 groups allocated for incoming and outgoing calls.

Page 201: Chapter 8 Configuring Survivable Remote Site Telephony
Telephony Survivable Remote Site Telephony (SRST) provides Cisco CallManager with fallback support for Cisco IP Phones that are attached to the Catalyst 4224 Access Gateway Switch (Catalyst 4224) on your local Ethernet. SRST enables the Catalyst 4224 to provide call handling support for Cisco IP Phones when a Cisco IP Phones lose connection to the remote primary, secondary, or tertiary Cisco CallManager or when the WAN connection is down.
Page 202: Overview Of Survivable Remote Site Telephony
WAN connection between the branch office Catalyst 4224 and Cisco CallManager fails or when connectivity with Cisco CallManager is lost, the Cisco IP Phones at the remote site are unusable for the duration of the failure. The SRST feature overcomes this problem, enabling the basic features of the Cisco IP Phones by providing call-handling support on the Catalyst 4224 for its attached Cisco IP Phones.

When the primary Cisco CallManager is restored, the displayed message is Note removed and you can access all the previous functionality of the Cisco IP Phone. Fallback Behavior When the Cisco IP Phones lose contact with all primary, secondary, and tertiary Cisco CallManagers, the phones re-home to the local SRST Catalyst 4224 to provide the call processing capability required to place and receive calls.

The message is brief because the Cisco IP Phone 7910 has only a two-line display area and the display panel is also used to display the telephone number.
Page 206 WAN connection to the branch office is down and that the Cisco IP Phones are able to make calls by being connected to the local SRST Catalyst 4224. This Catalyst 4224 acts as a fallback Cisco CallManager. The branch office Cisco IP Phones on the LAN network, connected to the PSTN, are capable of making off-net calls outside the network using the Catalyst 4224s.

In fax pass-through mode, the gateways do not distinguish a fax call from a voice call. The fax communication between the two fax machines is carried in-band over a “voice” call in its entirety. All Cisco voice gateways support fax pass-through.
Page 217: Cisco Fax Relay
If the two sides cannot negotiate on a common codec and speed, the fax fails. If negotiation is successful, fax transmission begins. Cisco fax relay is supported using MGCP or H.323, depending on the specific gateway type. The Cisco voice gateways support as many concurrent fax calls as G.711 voice calls.

Appendix B Synopsis of Basic VoIP Concepts A Voice Primer The coder-decoder compression schemes (codecs) are enabled for both ends of the connection using Real-Time Transport Protocol/User Datagram Protocol/Internet Protocol (RTP/UDP/IP) as the protocol stack. Any call-progress indications (or other signals that can be carried inband) are cut through the voice path as soon as an end-to-end audio channel is established.
Page 280: Codecs
Appendix B Synopsis of Basic VoIP Concepts A Voice Primer In response to the limitations of analog transmission, the telephony industry migrated to digital transmission using pulse code modulation (PCM) or adaptive differential PCM (ADPCM). In both cases, analog sound is converted into digital form by sampling the analog sound 8000 times per second and converting each sample into a numeric code.
