Cisco IP Phone 7960

The Cisco IP Phone 7960 provides the connectivity to the IP PBX system. The IP phone has two RJ-45 jacks for connecting to the external devices: a LAN-to-phone jack and a PC-to-phone jack. The jacks use either Category 3 or Category 5 unshielded twisted-pair (UTP) cable. The LAN-to-phone jack is used to connect the phone to the LAN using a crossover cable; a workstation or a PC can be connected to the PC-to-phone jack using a straight-through cable.

The inline power is designed to work in cables from Category 3, Category 4, Category 5, and later up to 100 meters. The inline power works with IBM Token Ring STP cable of 100 meters when used with a Token Ring to Fast Ethernet adapter (LanTel Silver Bullet SB-LN/VIP-DATA adapter).

Chapter 55 Configuring a VoIP Network

Cisco CallManager

Cisco CallManager is an open and industry-standard call processing system; its software runs on a Windows NT server and sets up and tears down the calls between the phones, integrating traditional PBX functionality with the corporate IP network. Cisco CallManager manages the components of the IP PBX system, the phones, the access gateways, and the resources for such features as call conferencing and media mixing. Each Cisco CallManager manages the devices within its zone and exchanges information with the Cisco CallManager in charge of another zone to make the calls possible across multiple zones. Cisco CallManager can work with the existing PBX systems to route a call over the Public Switched Telephone Network (PSTN).

Note For information on configuring Cisco CallManager to work with the IP devices that are described in this

chapter, refer to the Cisco CallManager Administration Guide, the Configuration Notes for Cisco CallManager, and the Cisco CallManager Remote Serviceability Users Guide publications.

Access Gateways

Understanding How a VoIP Network Works

The access gateways allow the IP PBX system to talk to the existing PSTN or PBX systems. The access gateways consist of analog station gateways, analog trunk gateways, digital trunk gateways, and a converged voice gateway.

These sections describe the gateways:

• Analog Station Gateway, page 55-5

• Analog Trunk Gateway, page 55-6

• Digital Trunk Gateway, page 55-6

• Converged Voice Gateway, page 55-7

Analog Station Gateway

The Catalyst 6500 series 24-port Foreign Exchange Station (FXS) analog interface module allows the plain old telephone service (POTS) phones and fax machines to connect to the IP PBX network. The analog station gateway behaves like the PSTN side for the POTS equipment. It requires an IP address, is registered with Cisco CallManager in its domain, and is managed by Cisco CallManager.

To configure the analog station interfaces, see the “Configuring VoIP on a Switch” section on

page 55-10. The module features are listed in Table 55-1.

Chapter 55 Configuring a VoIP Network

Analog Trunk Gateway

The Cisco access analog trunk gateways allow the IP PBX to connect to the PSTN or PBX. The gateway supports up to eight trunks to the PSTN and appears like a phone to the trunk lines coming from the PSTN. Using this gateway, the IP PBX places an IP call through the PSTN. Similar to the analog station gateway, the analog trunk gateway provides line echo cancellation and dual tone multifrequency (DTMF) tone generation and detection. The analog trunk gateway does not provide the ring voltage as it is not connected to the POTS end devices such as the POTS phones or fax machines. The analog trunk gateway requires an IP address, is registered with Cisco CallManager in its domain, and is managed by Cisco CallManager.

To configure the analog trunk gateways, refer to the documentation that shipped with the gateway.

Digital Trunk Gateway

The Catalyst 6500 series 8-port T1/E1 PSTN interface module can support both digital T1/E1 connectivity to the PSTN or transcoding and conferencing. The module requires an IP address, is registered with Cisco CallManager in its domain, and is managed by Cisco CallManager.

The module software is downloaded from a TFTP server. Depending upon which software you download, the ports can serve as the T1/E1 interfaces or the ports support transcoding and conferencing. The transcoding and conferencing functions are mutually exclusive. For every transcoding port in use, one less conferencing port is available and vice versa.

To configure the 8-port T1/E1 PSTN interfaces, see the “Configuring VoIP on a Switch” section on

page 55-10. The module features are listed in Table 55-2.

Converged Voice Gateway

The Cisco Voice Gateway 200 (VG200) allows you to connect the standard POTS phones (connected directly to the gateway or anywhere on the PSTN) with Cisco IP or any H.323-compliant telephony devices. When used with Cisco CallManager, the VG200 functions as a Media Gateway Control Protocol (MGCP) gateway. The Cisco VG200 provides a 10/100BASE-T Ethernet port for connection to the data network. The following telephony connections are also available:

• One to four Foreign Exchange Office (FXO) ports for connecting to a central office or PBX

• One to four FXS ports for connecting to POTS telephony devices

These ports can be used to integrate a VoIP network with POTS devices, PBXs, or the PSTN.

To configure the Cisco VG200, refer to the documentation that shipped with the gateway.

How a Call Is Made

An IP phone connects to a LAN either through a hub port or a switch port. The IP phone boots up and uses DHCP to get its IP address and the IP address of its TFTP file server. The IP phone uses its IP address to talk to the TFTP server and gets its configuration file. The configuration file includes the IP address of the phone’s Cisco CallManager(s). The phone then talks with Cisco CallManager and registers itself. Each time a phone boots up, it might get a different IP address. Cisco CallManager knows how to associate a consistent user phone number to a particular phone by using the MAC address of the phone. Cisco CallManager always maintains a table mapping the phone MAC address and phone number. Each time a phone registers, the table is updated with the new IP address. During the registration, Cisco CallManager downloads the key pad template and the feature capability for the phone. It tells the phone which run-time image it should use. The phone then goes to the TFTP server to get its run-time image. Each phone has a dedicated TCP connection to Cisco CallManager called the control channel. All control information, such as key pressing, goes from the phone to Cisco CallManager through this channel. Instructions to generate ring tone, busy tone, and so on comes from Cisco CallManager to the phone through this channel.

Cisco CallManager stores the IP-address-to-phone-number mapping (and vice versa) in its tables. When a user wants to call another user, the user keys in the called party’s phone number. Cisco CallManager translates the phone number to an IP address and generates an IP packet version of the ring tone to the called IP phone through the TCP connection. When the called IP phone receives the packet, it generates a ring tone. When the user picks up the phone, Cisco CallManager instructs the called IP phone to start talking with the calling party and removes itself from the loop. From this point on, the call goes between the two IP phones through the Real-Time Transport Protocol (RTP) which runs over the User Datagram Protocol (UDP). Because the voice packets are sensitive to delays, TCP is not suitable for voice transmission because the timeouts and retries increase the delay between the packets. When any change occurs during the call due to a feature being pressed on one of the phones, or one of the users hanging up or pressing the flash button, the information goes to Cisco CallManager through the control channel.

PSTN using FXO emulation

T1 channel bank using FXS emulation

PBX through a trunk (tie) line using ear and mouth (E&M) emulation

If a call is made to a number outside of the IP PBX network, Cisco CallManager routes the call to an analog or digital trunk gateway which routes it to the PSTN.

Understanding How VLANs Work

This section describes the native VLANs and the auxiliary VLANs. This section uses the following terminology:

• Auxiliary VLAN—Separate VLAN for IP phones

• Native VLAN—Traditional VLAN for data

• Auxiliary VLAN ID—VLAN ID of an auxiliary VLAN

• Native VLAN ID—VLAN ID of a native VLAN

Access port

When the IP phone connects to a 10/100 port on the Catalyst 6500 series switch, the access port (PC-to-phone jack) of the IP phone can be used to connect a PC.

The packets to and from the PC and to and from the phone share the same physical link to the switch and the same port of the switch. The various configurations are shown in the “Cisco IP Phone 7960” section

on page 55-2).

Introducing the IP-based phones into the existing switch-based networks raises the following issues:

• The current VLANs might be configured on an IP subnet basis, and additional IP addresses might

not be available to assign the phone to a port so that it belongs to the same subnet as other devices (PC) that are connected to the same port.

• The data traffic present on the VLAN supporting phones might reduce the quality of the VoIP traffic.

You can resolve these issues by isolating the voice traffic onto a separate VLAN on each of the ports that are connected to a phone. The switch port that is configured for connecting a phone would have separate VLANs that are configured for carrying the following:

• Voice traffic to and from the IP phone (auxiliary VLAN)

OL-8978-02

• Data traffic to and from the PC that is connected to the switch through the access port of the IP phone

(native VLAN)

Isolating the phones on a separate, auxiliary VLAN increases the quality of the voice traffic and allows a large number of phones to be added to an existing network where there are not enough IP addresses. A new VLAN means a new subnet and a new set of IP addresses.

Catalyst 6500 Series Switch Software Configuration Guide—Release 8.7

55-9

Understanding How CDP and VoIP Work

Cisco Discovery Protocol (CDP) was enhanced in software release 8.1(1) to facilitate backward compatibility with the newer, higher-powered Cisco IP phones. With this enhanced CDP, a Cisco IP phone can negotiate its power requirements to the switch within the CDP packet. The switch uses this information to ensure that it does not oversubscribe the available power.

We recommend that you enable CDP on the switch so that the switch can correctly detect and supply power to the IP phones that are connected to it. CDP is enabled on the Catalyst 6500 series switches by default; however, you should confirm that CDP is enabled when setting up your VoIP network. For more information on CDP, see Chapter 31, “Configuring CDP.”

Configuring Per-Port Power Management

This section describes the per-port power management and the CLI commands that are used to configure power management for IP phones.

Note To determine the exact power requirements for your configuration to ensure that you are within the

system power budget, see the “Generating a System Status Report” section on page 22-16.

Note This section applies to the Ethernet switching modules with the voice daughter card only. For

information on powering the IP phones that are connected to the other Ethernet switching modules, refer to the Catalyst Family Inline-Power Patch Panel Installation Note publication.

For each IP phone that is connected to an Ethernet switching module with a voice daughter card installed, the module allocates part of the available system power to power up and run the phone. You can apply the power on an individual port basis.

Only one IP phone can be powered per port; the phone must be connected directly to the switch port. If a second phone is daisy chained off the phone that is connected to the switch port, the second phone cannot be powered by the switch.

• auto—Discovery is enabled and the supervisor engine directs the switching module to power up the

port only if the switching module discovers the phone. You can specify the maximum wattage that is allowed on the port. If you do not specify a wattage, then the switch will deliver no more than the hardware-supported maximum value.

• static—Discovery is enabled and the supervisor engine directs the switching module to power up

the port to the wattage that you specify only if the switching module discovers the phone. You can specify the maximum wattage that is allowed on the port. If you do not specify a wattage, then the switch allows the hardware-supported maximum value. The maximum wattage, whether determined by the switch or specified by you, is preallocated to the port. If the switch does not have enough power for the allocation, the command will fail.

• off—Discovery is disabled which prevents the port from providing power to an external device. If the

external device is wall-powered and the inline power is off, the port should still link up, join the bridge group, and go to the STP forwarding state.

• limit—Discovery is enabled. This mode provides you with the option to limit the power allocated for an

external device. If the wattage value that you specify with the limit keyword is less than the power determined through IEEE classification, instead of denying power, the minimum of these two values is allocated. If the device consumes more than the configured value, the port is shut down and an appropriate syslog message is displayed. The limit keyword is not supported on all modules. To check if the limit keyword is supported on a module, enter the show environment power mod command. If the output of the command indicates support for per-port power monitoring, the mode is supported.

• max-wattage—(Optional) The maximum power allowed on the port in either auto or static mode; valid

values are from 4000 to 15400 milliwatts.

Each port also has a status that is defined as one of the following:

• on—Power is supplied by the port.

• off—Power is not supplied by the port.

• Power-deny—The supervisor engine does not have enough power to allocate to the port, or the

• err-disable—The port is unable to provide the power to the connected device that is configured in

Static mode.

Power Requirements

The IP phones may have different power requirements. Table 55-4 lists the power requirements for the different classes of IP phones. The supervisor engine initially calculates the power allocation for each port based on the per-port configuration, classification (IEEE only), and default power. When the correct amount of power is determined from the CDP messaging with the Cisco IP Phone, the supervisor engine reduces or increases the allocated power for any ports that are set to Auto mode. The allocated power is not adjusted for ports that are set to Static mode.

For example, the default allocated power is 7 W for a Cisco IP Phone requiring 6.3 W. The supervisor engine allocates 7 W for the Cisco IP Phone and powers it up. Once the Cisco IP Phone is operational, it sends a CDP message with the actual power requirement to the supervisor engine. The supervisor engine then decreases the allocated power to the required amount if the port is set to Auto mode. If the port is set to Static mode, the supervisor engine allocates the wattage that you specified. If the port is set to off, the supervisor engine does not allot any power to the port.

Available Power

Table 55-5 lists the available power that can be supplied for each port for the voice daughter cards.

Table 55-5 Efficiency of Voice Daughter Cards

WS-F6K-GE48-AF 15 89%

WS-F6K-FE48-AF 15 89%

WS-F6K-FE96-AF 15 89%

For example, if the powered device requires 6.3 W, then the allotted power for that port using a daughter card with 89 percent efficiency must be 6.3/(0.89) = 7 W. If you are using a voice daughter card with 100 percent efficiency, then the allotted power is 6.3 W.

Maximum Power Per Port (W) Efficiency

Wall-Powered Phones

Powering Off the Phone

Phone Removal

When a wall-powered phone is present on a switching module port, the switching module cannot detect its presence. The supervisor engine discovers the phone through CDP messaging with the port. If the phone supports the inline power (the supervisor engine determines this through CDP), and the mode is set to Auto, Static, or Off, the supervisor engine does not attempt to power on the port. If a power outage occurs, and the mode is set to Auto, the phone loses power, but the switching module discovers the phone and informs the supervisor engine, which then applies the inline power to the phone. If a power outage occurs, and the mode is set to Static, the phone loses power, but the switching module discovers the phone and applies the preallocated inline power to the phone.

The supervisor engine can turn off power to a specific port by sending a message to the switching module. The power for a port in Auto mode is then added back to the available system power. The power for the ports in Static mode is not added back to the available system power. This situation occurs only when you power off the phone through the CLI or SNMP.

The switching module informs the supervisor engine if a powered phone is removed using a link-down message. The supervisor engine then adds the allocated power for that port back to the available system power.

In addition, the switching module informs the supervisor engine if an unpowered phone is removed.

OL-8978-02

Caution When a phone cable is plugged into a port and the power is turned on, the supervisor engine has a

4-second timeout waiting for the link to go up on the line. During those 4 seconds, if the phone cable is unplugged and a network device is plugged in, the device could be damaged. We recommend that you wait at least 10 seconds between unplugging a device and plugging in a new device.

Configuring VoIP on a Switch

High-Availability Support

To support high availability during a failover from the active supervisor engine to the standby supervisor engine, the per-port power management and phone status information is synchronized between the active and standby supervisor engines.

The information to be synchronized (on a per-port basis) is the presence of a phone, the phone power status (on, off, denied, or faulty), allocated power, device class, device type, device maximum power, and device discovery. The active supervisor engine sends this information to the standby supervisor engine, and the standby supervisor engine updates its internal data structures. When a switchover occurs, the standby supervisor engine allocates the power to the modules and ports from the available power, one module at a time. Once the power for each module has been allocated, the supervisor engine allocates the power to the phones, beginning with the lowest slot number, until all inline powered ports have been either powered on, off, or denied.

Setting the Power Mode of a Port or a Group of Ports

To set the power mode of a port or a group of ports, perform this task in normal mode:

Task Command

Set the power mode of a port or a group of ports. set port inlinepower mod/port {[auto | static]

Note If you configure the max-wattage values that are multiples of 500 on a Catalyst 6500 series switch with

the set port inlinepower mod/port static | auto max-wattage command, the power that is drawn from the global allocation is possibly slightly smaller than the power that is reported in the Total PWR Allocated to Module field of the show environment power command. This discrepancy is due to the internal conversion of units from Watts to cAmps and back to Watts. The difference between the total allocated power and the total power that is drawn from the system is no more than +/- 0.42 W.

This example shows how to set the power mode of a port or group of ports:

Console> (enable) set port inlinepower 2/5 off Inline power for port 2/5 set to off. Console> (enable) set port inlinepower 2/3-9 auto 800 Inline power for ports 2/3-9 set to auto and max-wattage to 800. Console> (enable)

Configuring VoIP on a Switch

[max-wattage] | off}

Setting the Default Power Allocation

The set inlinepower defaultallocation command is global and only affects Cisco IP phones. The inline power threshold notification generates a syslog message when the inline power usage exceeds the specified threshold. To set the default power allocation, perform this task in privileged mode (the default allocation value is 15400 milliwatts):

Caution The set inlinepower defaultallocation command can be harmful when there is not enough power in the

system to bring up all connected inline power devices. If you set a small value for the power allocation, all connected inline power devices initially will be powered up. However, after receiving CDP messages, the system will learn that devices are consuming more power and deny power to some of the ports. Setting a small value might also result in the overdrawing of power for some time with unanticipated results, such as hardware failures and unexpected resets.

Note 7000 milliwatts is the maximum power supported for these modules: WS-X6348-RJ21V,

WS-X6348-RJ-45V, WS-X6148-RJ-45V, and WS-X6148-RJ21V.

Use the set inlinepower notify-threshold command to set a threshold for inline power usage. The threshold is a percentage from 1 through 99, with 99 percent being the default. When the threshold is passed, a syslog and trap (if configured) are generated.

To set the inline power notification threshold for a module, perform this task in privileged mode:

Configuring the Auxiliary VLANs on Catalyst LAN Switches

These sections describe how to configure auxiliary VLANs:

• Understanding the Auxiliary VLANs, page 55-20

• Auxiliary VLAN Configuration Guidelines, page 55-21

• Configuring the Auxiliary VLANs, page 55-21

• Verifying the Auxiliary VLAN Configuration, page 55-22

• Disabling the Auxiliary VLANs Until an IP Phone is Detected, page 55-22

Understanding the Auxiliary VLANs

You can configure the switch ports to send CDP packets that instruct an attached Cisco IP Phone 7960 to transmit the voice traffic to the switch in these frame types:

• 802.1Q frames carrying the auxiliary VLAN ID and Layer 2 CoS set to 5 (the switch port drops all

802.1Q frames except those carrying the auxiliary VLAN ID).

–

Reset the Cisco IP Phone 7960 if the auxiliary VLAN ID changes.

–

Enter the set port auxiliaryvlan mod[/port] aux_vlan_id command.

Note We recommend that you use 802.1Q frames and a separate VLAN.

• 802.1p frames, which are 802.1Q frames carrying VLAN ID 0 and Layer 2 CoS set to 5 (enter the

set port auxiliaryvlan mod[/port] dot1p command).

• 802.3 frames, which are untagged and carry no VLAN ID and no Layer 2 CoS value (enter the set

port auxiliaryvlan mod[/port] untagged command).

Note The Cisco IP Phone 7960 always sets the Layer 3 IP precedence to 5 in the voice traffic.

Chapter 55 Configuring a VoIP Network

Auxiliary VLAN Configuration Guidelines

This section describes the guidelines for configuring the auxiliary VLANs:

• An auxiliary VLAN port is operationally a trunk, even though it is not treated like a “normal” trunk

port. When an auxiliary VLAN is added to a port and the set dot1q-all-tagged command is enabled, the set dot1q-all-tagged command tags the native VLAN on the port where the auxiliary VLAN is configured. A port with an auxiliary VLAN configured is not viewed as an 802.1Q trunk in the show trunk command output, but the port acts like an 802.1Q trunk if the set dot1q-all-tagged command is enabled.

• The IP phone and a device that is attached to the phone are in the same VLAN and must be in the

same IP subnet if one of the following occurs:

–

They use the same frame type.

–

The phone uses 802.1p frames, and the device uses untagged frames.

–

The phone uses untagged frames, and the device uses 802.1p frames.

–

The phone uses 802.1Q frames, and the auxiliary VLAN equals the native VLAN.

• The IP phone and a device that is attached to the phone cannot communicate if they are in the same

VLAN and subnet but use different frame types, because the traffic between the devices in the same subnet is not routed (routing would eliminate the frame type difference).

• You cannot use the switch commands to configure a frame type that is used by the traffic that is

received from a device that is attached to the phone’s access port.

• With software release 6.2(1) and later releases, the dynamic ports can belong to two VLANs—a

native VLAN and an auxiliary VLAN. See Chapter 19, “Configuring Dynamic Port VLAN

Membership with VMPS,” for the configuration details for the auxiliary VLANs.

Disabling the Auxiliary VLANs Until an IP Phone is Detected

With software release 8.3(1) and later releases, this feature provides security for the auxiliary VLANs by ensuring that the auxiliary VLAN is not enabled until an IP phone is detected. As soon the switch detects the presence of an IP phone, the auxiliary VLAN is enabled.

The presence of an IP phone is determined through the CDP packet exchange between the switch and the phone. This detection method is used for both the inline-powered and wall-powered IP phones.

Note If the auxiliary VLAN ID equals the port-VLAN ID or when the auxiliary VLAN ID is configured as none,

dot1p, or untagged, this feature cannot be applied to the port. If any command entry results in the auxiliary

VLAN ID equaling the port-VLAN ID, the feature is disabled and the following warning message is displayed: “cdpverify feature on port <mod>/<port> is disabled.”

To enable or disable the auxiliary VLAN IP phone detection, perform this task in privileged mode (the default is disabled):

Configuring a Port Voice Interface

If DHCP is enabled for a port, the port obtains all other configuration information from the TFTP server. When disabling DHCP on a port, you must specify some mandatory parameters as follows:

• If you do not specify the DNS parameters, the software uses the system DNS configuration on the

supervisor engine to configure the port.

• 8-port T1/E1 PSTN interface module only: You cannot specify more than one port at a time because

a unique IP address must be set for each port.

Understanding How QoS Works in the Cisco IP Phone 7960

Note The Cisco IP Phone 7960 always sets the Layer 3 IP precedence and Layer 2 CoS to 5 in the voice traffic

that is generated by the phone. The Layer 3 IP precedence and Layer 2 CoS values in the voice traffic that is generated by the phone are not configurable.

55-31

Configuring VoIP on a Switch

You can configure the Cisco IP Phone 7960 access port (see Figure 55-5) to either trusted or untrusted mode.

In untrusted mode, all the traffic in the 802.1Q or 802.1p frames that are received through the access port is marked with a configured Layer 2 CoS value. The default Layer 2 CoS value is 0. The untrusted mode is the default when the phone is connected to a Cisco LAN switch.

In trusted mode, all the traffic that is received through the access port passes through the phone switch unchanged. The trusted mode is the default when the phone is not connected to a Cisco LAN switch.

The traffic in the frame types other than 802.1Q or 802.1p passes through the phone switch unchanged, regardless of the access port trust state.

• Cisco IP Phone 7960

QoS and Cisco IP Phone Configuration

The Cisco IP Phones are directly attached to the Catalyst 6500 series switch ports. Typically, the traffic that is coming from the phone and entering the switch is marked with a tag using the 802.1Q header. The header contains the VLAN information and the class of service (CoS) 3-bit field. The CoS determines the priority of the packet. For most Cisco IP Phone configurations, the traffic that comes from the phone and enters the switch is trusted to ensure that the voice traffic is properly prioritized over other types of traffic in the network. The port on the switch where the phone is attached is configured to trust-cos, which means that the port trusts the CoS labeling of all packets arriving on that port.

Chapter 55 Configuring a VoIP Network

QoS, Cisco IP Phone, and PC Configuration

A PC or workstation can be attached to the Cisco IP Phone. The phone has a built-in hub that mixes the traffic coming from the PC, the phone, and the switch port. To distinguish the traffic that comes from the PC from the traffic that comes from the phone, use the 3-bit CoS labels.

You need to configure the QoS features on the phone for proper labeling to occur. The QoS configuration information is sent to the phone using CDP from the switch. The QoS configuration determines the trust state of the phone and the classification information (Ext-Cos). The phone supports two trust states:

• Trusted

• Untrusted and marked with a new COS value (Ext-Cos)

If the phone is in trusted mode, all the labels that are produced by the PC are sent directly through the phone toward the switch, untouched. If the phone is in untrusted mode, all traffic coming from the PC is marked with the Ext-Cos value before it is sent to the switch.

For most setups, the PC or workstation that is attached to the phone is unable to tag its packets. In these cases, all the traffic that comes from the PC and enters the switch through the phone, is marked with the “default ext-cos” that is configured on the phone.

In some cases, the PC can tag its own packets. A PC running Windows 2000 can be configured to send the 802.1Q frames of any priority. To solve this problem, the phones should be configured to be untrusted, which marks all the traffic coming from the PC to the appropriate priority.

The trusted boundary prevents the users from taking advantage of the trust-cos setting on the switch by disconnecting their phone from the network and plugging their PC directly into the switch port. It uses CDP to detect the phone’s presence on a port. If the phone leaves the port, the feature automatically configures the port to be untrusted, which solves the security issue.

The trusted boundary is implemented using a configuration command to create a new type of trust. The command allows you to configure the port trust based on the presence of a given device on a port. For the Cisco IP Phones, you configure the trust as “trust-device ciscoipphone.”

Catalyst 6500 Series Switch Software Configuration Guide—Release 8.7

OL-8978-02

Chapter 55 Configuring a VoIP Network

Trusted Boundary Configuration Guidelines

This section describes the guidelines for configuring the trusted boundary:

• Common Open Policy Service (COPS) considerations

COPS directly affects how the QoS parameters are applied. A port may have either a local policy or a COPS policy. This setting specifies whether the port should get its QoS configuration information from the local configuration or through a COPS server. If COPS is enabled on a port and is also globally enabled, the policy that is specified by the COPS server applies. If COPS is disabled and/or the run-time policy is local, the local configuration QoS policy applies. The extended trust boundary feature overrides the “local” policy on a port.

• QoS configuration support

All the QoS port trust configuration settings are supported (trust-cos, trust-ipprec, trust-dscp), but you should use trust-cos for the Cisco IP Phone networks.

• System log messaging

New QoS syslogs were added for the trusted boundary to notify you of the changes to a port’s trust state and to warn of improper configuration. To see these syslogs, set the QoS logging level to 5 (set logging level qos 5). The default is 3. Refer to the Catalyst 6500 Series System Message Guide for the descriptions of the syslogs.

Configuring VoIP on a Switch

• Final run-time port trust value

The final run-time port trust on any port is dependent on the following:

–

Trusted boundary configuration

–

Phone’s presence on the port

–

QoS configuration

–

COPS configuration

To enable the trusted boundary, you must enable QoS and you must enable CDP globally and on the port, running in version 2 mode. You must set COPS to local policy (the COPS default) or to disabled (the COPS default). When ciscoipphone is configured as the trust-device on the port, the feature is enabled and detects the presence of a Cisco IP Phone and sets the trust values.

See Figure 55-6 to determine the final trust value on a port.

Verifying a Port’s Trust-Device State

To verify a port’s trust-device state, perform this task in normal mode:

Task Command

When the trusted boundary is active, the run-time trust state of the port changes depending on the presence of the phone.

Note The moment that the phone leaves the switch port, there is a slight convergence time for the port to

change to the untrusted state (a maximum time of 15 seconds).

Using SmartPorts

The SmartPorts feature consists of two macros that simplify voice configuration on the Catalyst 6500 series switches. The SmartPorts macros cover all the voice configuration tasks that are required for implementing the recommended Architecture for Voice, Video, and Integrated Data (AVVID) settings for a voice port.

SmartPorts focuses on the voice networks that are built using the Cisco IP Phone 79xx series and the Cisco SoftPhone. With SmartPorts, you use the ciscoipphone or ciscosoftphone keywords to initiate the macros that specify the type of voice parameters that you desire on a particular port.

Understanding SmartPorts Macros

When you execute the SmartPorts macros on a port using the ciscoipphone or ciscosoftphone keywords, these features are implemented:

• The port is enabled.

• The Layer 2 protocol is disabled for CDP, STP, and VTP.

• The port membership is set to “static.”

• The set port host command is executed on the port.

55-38

• The specified data VLAN is associated with the port.

• The global automatic QoS command is executed.

Catalyst 6500 Series Switch Software Configuration Guide—Release 8.7

OL-8978-02

Chapter 55 Configuring a VoIP Network

When you execute the ciscoipphone keyword on a port, in addition to the previous features, these features are also implemented:

• The specified auxiliary VLAN is associated with the port.

• The inline power is enabled.

• CDP is enabled globally and on the port.

• CDP is configured to version v2.

• The port-based automatic QoS command for the Cisco IP phone is executed.

When you execute the ciscosoftphone keyword on a port, in addition to the previous features, these features are also implemented:

• The auxiliary VLAN for the port is set to “none.”

• The port-based automatic QoS command for the Cisco SoftPhone is executed.

SmartPorts—Cisco IP Phone

In most configurations, the Cisco IP Phone 79xx is connected directly to the Catalyst switch port. Optionally, you can attach a PC to the phone and use the phone as a hop to the switch.

Typically, the traffic that comes from the phone and enters the switch is marked with a tag using the

802.1Q/p header. The header contains the VLAN information and the CoS 3-bit field. The CoS determines the priority of the packet. The switch uses the CoS field to distinguish the PC traffic from the phone traffic. The switch can also use the DSCP field for the same purpose.

In most Cisco IP Phone 79xx configurations, the traffic that comes from the phone and enters the switch is trusted. You set the port trust to trust-cos to properly prioritize the voice traffic over other types of traffic in the network.

Using SmartPorts

The Cisco IP Phone 79xx has a built-in switch that mixes the traffic that comes from the PC, the phone, and the switch port. The Cisco IP Phone 79xx has the trust and classification capabilities that you need to configure.

The ports that connect the IP phones need to have several features enabled or disabled. SmartPorts ensures that the necessary features are enabled. Most of these features are implemented when you execute the set port host command (such as disabling channels, enabling PortFast, and so on). A VLAN and an auxiliary VLAN must be configured on the port for QoS to work. The inline power needs to be enabled (if available), and CDP must be enabled for the trusted boundary feature to work. QoS configuration is handled by the automatic QoS feature (see Chapter 52, “Using Automatic QoS”).

SmartPorts—Cisco Softphone

The Cisco SoftPhone is a software product that runs on a standard PC and emulates an IP phone. The main difference between the Cisco SoftPhone and the Cisco IP Phone 79xx is that the Cisco SoftPhone marks its voice traffic through a DSCP, while the Cisco IP Phone 79xx marks its traffic through a CoS. The QoS settings on the switch accommodate this behavior by trusting the Layer 3 marking of the traffic entering the port. All other behavior is similar to the Cisco IP Phone 79xx. Some features, such as CDP, do not need to be enabled because the trusted boundary does not support Cisco SoftPhone.

• CDP Dependencies, page 55-40

• EtherChannel Considerations, page 55-40

• PFC/PFC2 Support, page 55-40

• Module Support, page 55-40

Supported Phones

When you use SmartPorts with the ciscoipphone keyword, some of the QoS configuration requires phone-specific configuration (trust-ext, ext-cos) which is supported only on the following phones: Cisco IP Phone 7910, Cisco IP Phone 7940, Cisco IP Phone 7960, and Cisco IP Phone 7935. However, the ciscoipphone keyword is not exclusive to these models only; any phone can benefit from all the other QoS settings that are configured on the switch.

Chapter 55 Configuring a VoIP Network

The Cisco SoftPhone is supported through the ciscoipsoftphone keyword.

CDP Dependencies

To configure the QoS settings and the trusted boundary on the Cisco IP Phone, you must enable CDP version 2 or later on the port.

You need to enable CDP only for the ciscoipphone QoS configuration; CDP does not affect the other components of the SmartPorts feature.

EtherChannel Considerations

The SmartPorts commands do not support channeling.

PFC/PFC2 Support

No PFC or PFC2 is required for the ciscoipphone keyword. A PFC or PFC2 is required for the ciscosoftphone keyword.

Module Support

The ciscoipphone keyword is supported only on the 10/100 and 10/100/1000 Ethernet ports.

The ciscosoftphone keyword is supported on all Ethernet ports.

Configuring User-Definable SmartPorts Macros

Using SmartPorts

Overview

These sections describe how to define and implement SmartPorts macros:

• Overview, page 55-47

• Using the CLI to Configure User-Definable SmartPorts Macros, page 55-48

This section describes the user-definable SmartPorts macros:

• Creating a macro—The user-definable macro approach is similar in concept to the alias command.

The alias command is an alias for only one command; the user-definable macro approach creates a command set macro for one or more commands. The macros are created using the set macro name name command after which you enter a list of commands that become part of the macro.

• Creating variables for macros—When defining macros, some commands require parameters that

need to be specified by variables (such as the VLAN ID for Ethernet ports or the IP address for ACLs). The variables are defined as “'keyword-value” pairs, where the first parameter must be the name of the variable and the second parameter is its value. Each variable can be defined on a per-port or global basis. The variables are created using the set macro variable name_of_variable variable_value mod/port command. The variables and their values are stored in the switch in a table/database. When a macro with a variable in its definition is applied to a port, the macro takes the values from the table/database and executes the commands in the macro.

• Displaying macros and variable definitions—To display macros and their variable definitions, enter

the show macro macro-name command and the show macro variable [all] [name name_of_macro] [mod/port] command.

• Applying a macro—After you create a macro, it needs to be applied to a port. When the macro is

applied to a port, if the macro contains any variables, the variables are replaced with the respective values that are predefined in the table/database, and then the commands in the macro definition are executed. To apply a macro to a port, enter the set port macro mod/port name_of_macro command.

OL-8978-02

Catalyst 6500 Series Switch Software Configuration Guide—Release 8.7

55-47

Using SmartPorts

• Clearing (deleting) a macro—You can clear a macro when it is no longer needed. When you clear a

macro, only the macro and its definition are cleared from the system; the configuration on the ports that the macro was applied to is not cleared. To clear a macro, enter the clear macro name command.

• Types of macros—The two types of macros are the global macros and the port-based macros.

• Displaying Macro Port Mappings, page 55-54

• Displaying the User-Definable SmartPorts Macro Configuration, page 55-55

• Configuring a Macro within a Macro, page 55-55

Creating User-Defined Macros

To create (define) a macro, use the set macro name name command to enter a list of commands (one command per line). To end the macro and exit from the macro mode, type the @ break character and then press Enter. An example is as follows:

Console> (enable) set macro name videophone Enter macro commands one per line. End with character ‘@’.

set port enable #MODPORT set vlan $DATAVLAN #MODPORT set port auxiliaryvlan #MODPORT $AUXVLAN set qos autoqos @

Console> (enable)

Follow these guidelines and restrictions when creating user-defined macros:

• The maximum length of a macro name is 16 characters. The maximum number of command lines in

a macro is 64. A macro cannot have the same name as a static macro (such as ciscoswitch or ciscorouter).

• You can have a macro inside a macro in user-defined and static macros.

• Syntax checking is not done when you create or modify a macro. If you enter incorrect commands

when creating the macro, the incorrect commands fail when the macro is applied to a port.

• In the above example, #MODPORT is a variable that specifies the port to which the macro is applied.

If the macro is applied on port 3/2, then #MODPORT is replaced by 3/2 when the macro is applied to a port.

55-48

Catalyst 6500 Series Switch Software Configuration Guide—Release 8.7

OL-8978-02

Chapter 55 Configuring a VoIP Network

• In the above example, $DATAVLAN and $AUXVLAN are variables and are substituted with

appropriate values when the macro is applied to a port.

• After the macro is defined, it is stored in NVRAM.

Modifying Existing User-Defined Macros

To modify an existing user-defined macro, use the set macro name name command. When modifying a macro, the new definition replaces the old definition but the new definition is not automatically applied to all the ports on which it was previously applied. You need to explicitly apply the modified macro. An example is as follows:

Console> (enable) set macro name fileserver Enter macro commands one per line. End with the character '@'. cmd1 cmd2 @ Console> (enable)

The macro named “fileserver” can be overwritten by creating a macro with the same name and new definitions. An example is as follows:

Console> (enable) set macro name fileserver Enter macro commands one per line. End with the character '@'. cmd2 cmd3 @ Warning: The macro fileserver has been modified; Do you want to modify (y/n) y Console> (enable)

Using SmartPorts

Defining Variables

To define a variable, use the set macro variable name_of_variable variable_of_value [mod/port] command. You can define the variable on a per-port basis or a global basis. When a macro is applied to a port, the variables are replaced with the values that you have defined. The maximum length of a variable name is 16 characters. A macro definition can use multiple variables in a single line. Per-port variables are defined on a per-port basis. Individual ports can be configured with different values by defining variables with different values for different ports. If a variable definition does not have port information, then it is treated as a global variable. The global variable definition is used if the per-port variable is not defined. An example is as follows:

Console> (enable) set macro variable $DATAVLAN 3 3/2

Variable DATAVLAN successfully created Console> (enable) set macro variable $DATAVLAN 5 3/3 Console> (enable) set macro variable $AUXVLAN 4 3/2

Variable AUXVLAN successfully created Console> (enable)

If a port is not specified in the variable definition, the variable is considered a global variable. An example is as follows:

Console> (enable) set macro variable $CDPVER v2

Variable CDPVER successfully created Console> (enable)

Console> (enable) set macro variable $DATAVLAN 77 Console> (enable)

OL-8978-02

Catalyst 6500 Series Switch Software Configuration Guide—Release 8.7

55-49

Using SmartPorts

Using Special Variables

Chapter 55 Configuring a VoIP Network

In the above examples, $CDPVER is a global variable and $DATAVLAN and $AUXVLAN are per-port variables. $DATAVLAN is also defined as a global variable. If a macro is using the variable $DATAVLAN and the macro is applied to a port other than ports 3/2 or 3/3, the macro would use the value of 77 for that port. After a variable and its values are defined, they are stored in NVRAM.

A macro could have a variable that is not predefined; the variable would get its value when the macro is applied. #MODPORT is one such variable. For example, assume that a macro has the variable #MODPORT in its definition. When the macro is applied on a module/port, the variable #MODPORT is replaced by the module/port (mod/port) on which the macro is applied. An example is as follows:

Console> (enable) set macro name videophone Enter macro commands one per line. End with character @. set port enable #MODPORT set vlan $DATAVLAN #MODPORT set port auxiliaryvlan #MODPORT $AUXVLAN @ Console> (enable)

In the above example, #MODPORT is a special variable that gets its value when the macro videophone is applied on a port.

Note #MODPORT is currently the only special variable supported.

Applying a User-Defined Macro

After the macro is created, it can be applied to a port. When a macro is applied to a port, the commands in the macro definition are executed on the switch. If the commands in the macro definition use any variables, the variables are replaced by their respective user-defined values and then the commands are executed. Use the set port macro mod/port name_of_macro command to apply a macro to a port.

To create and execute a user-defined macro, perform these steps:

Step 1 Create the macro by entering the following commands:

Console> (enable) set macro name videophone Enter macro commands one per line. End with character @.

set port enable #MODPORT set vlan $DATAVLAN #MODPORT set port auxiliaryvlan #MODPORT $AUXVLAN @

Macro videophone successfully created Console> (enable)

Step 2 Define the macro variables by entering the following commands:

Console> (enable) set macro variable $DATAVLAN 3 3/2

Variable DATAVLAN successfully created Console> (enable) set macro variable $DATAVLAN 5 3/3 Console> (enable) set macro variable $AUXVLAN 4 3/2

55-50

Catalyst 6500 Series Switch Software Configuration Guide—Release 8.7

Chapter 55 Configuring a VoIP Network

Variable AUXVLAN successfully created Console> (enable) set macro variable $AUXVLAN 77 3/7 Console> (enable) set macro variable $DATAVLAN 99 Console> (enable) set macro variable $CDPVER v2

Variable CDPVER successfully created Console> (enable)

Step 3 Apply the macro on port 3/2 by entering the following commands:

Console> (enable) set port macro 3/2 videophone

Before the macro is applied, the $DATAVLAN and $AUXVLAN variables are replaced by “3” and “4,” respectively, and then the following commands are executed:

set port enable 3/2 set vlan 3 3/2 set port auxiliaryvlan 3/2 4 set cdp enable set cdp version v2 set qos autoqos

Step 4 Apply the macro on port 3/7 by entering the following commands:

Console> (enable) set port macro 3/7 videophone

Using SmartPorts

Before the macro is applied, the $AUXVLAN variable is replaced by “77.” $DATAVLAN is not defined for port 3/7, so the macro searches the list of global variables and finds $DATAVLAN. In this case, the $DATAVLAN variable is replaced by the global definition “99,” and then the following commands are executed:

set port enable 3/7 set vlan 99 3/7 set port auxiliaryvlan 3/7 77 set cdp enable set cdp version v2 set qos autoqos

Follow these guidelines and restrictions when applying user-defined macros:

• If you attempt to apply a macro on a port and the macro has a variable that is not defined in its

definition, the macro is not applied on the port and an appropriate error message is displayed. This error response does not affect the definition of the macro.

• If you attempt to apply a macro on a port and the macro has some valid and some invalid commands

in its definition, the macro is still applied on the port and an appropriate error message is displayed when the invalid command is executed. This error response does not affect the definition of the macro.

• When you apply a macro, a record of the macro being applied is not stored in the configuration file

or NVRAM. However, each port has a record of the latest macro that was applied to it.

• Once a macro is applied to a port, you cannot clear the macro. However, one way to back out a macro

on a port is to define another macro that clears the configurations on the port and then apply the newly created macro on the port.

Clearing Macros and Macro Variables

When you clear a macro by entering the the clear macro name name_of_macro command, you clear the commands from the macro and remove the macro from the switch. The configurations that were applied using the macro that is being cleared are retained. If the macro that is being cleared is using any variables, and if the variables are not being used by any other macros, the variables are automatically cleared.

This section describes the various methods of clearing macros and macro variables:

• The syntax is as follows:

clear macro name name_of_macro

clear macro all

clear macro variable [all] [name_of_variable] [mod/ports]

• Clear an individual macro and its variables by entering the the clear macro name name_of_macro

command as follows:

Console> (enable) clear macro name videophone

Clearing macro videophone....

Cleared Macro videophone ....

Console> (enable)

Configuring a Macro within a Macro

OL-8978-02

You can have a macro within a macro definition. When the root macro is applied to a port, the macro inside the root macro gets replaced by its definition and the root macro is applied to the port. You can also have a static macro (such as ciscoswitch or ciscorouter) inside a user-defined macro definition.

Note If there is a macro inside a macro definition and if the root macro is applied on a port, the root macro is

displayed by entering the show macro map commands.
