Configuring DSCP Policing and Media Bandwidth Policing

This module explains the following features:

  • AS SIP—DSCP Policing

  • AS SIP—Media Bandwidth Policing

The Assured Services over Session Initiation Protocol Differentiated Services Code Point (AS SIP—DSCP Policing) Policing and the AS SIP—Media Bandwidth Policing feature adds the media policy functionality to the Cisco Unified Border Element (Cisco UBE) on a per-call basis to control the bandwidth. Real Time Protocol (RTP) packets are dropped, and MIB and system logs are generated if there is any DSCP policy, marking, and media bandwidth profiling violation.

Feature Information

AS SIP—DSCP Policing

15.2(2)T

The AS SIP—DSCP Policing feature provides the following functionalities:

  • A mechanism to map the RPH to the DSCP values in the IP header for audio and video calls.

  • A policy to match DSCP values of incoming media calls to the preconfigured value and take an action depending upon the configuration.

The following commands were introduced or modified:

dscp media , dscp-profile , snmp enable peer-trap , snmp-server enable traps voice (dscp profile) , violation , voice-class sip resource priority dscp-profile .

AS SIP—Media Bandwidth Policing

15.2(2)T

The AS SIP—Media Bandwidth Policing feature introduces traffic policing on the Cisco UBE to limit media bandwidth usage to the negotiated rate. Excess traffic is dropped when the traffic rate reaches the configured maximum value.

The following commands were introduced or modified:

media police-profile , media profile police , overhead , police profile , violation (media profile) .

Restrictions for Configuring DSCP Policing and Media Bandwidth Policing

Following are the restrictions for the AS SIP—DSCP Policing feature:

  • The Session Description Protocol (SDP) pass-through feature along with Resource Priority Header (RPH) to DSCP marking and policing are not supported.

  • High availability (HA) is not supported.

Following are the restrictions for the AS SIP—Media Bandwidth Policing feature:

  • The SDP pass-through feature along with the Media Bandwidth Policing feature are not supported.

  • Flow-around cases are not applicable to the Media Bandwidth Policing feature.

  • HA is not supported.

Information About Configuring DSCP Policing and Media Bandwidth Policing

AS SIP—DSCP Policing

The AS SIP—DSCP Policing feature provides the following functionalities:

  • A mechanism to map the RPH to the DSCP values in the IP header for audio and video calls.

  • A policy to match DSCP values of incoming media calls to the preconfigured value and take an action depending upon the configuration.

You must map RPH to DSCP values to provide priority and precedence for VoIP calls at all layers. DSCP policing and marking are supported as part of the AS SIP—DSCP Policing feature for RTP media. The DSCP policing functionality checks DSCP values for media packets (RTP) and informs incorrect marking of DSCP values. The DSCP marking functionality marks packets with the correct DSCP value as per the SIP RPH.

The AS SIP—DSCP Policing feature supports two new namespaces, UC and CUC. The namespace support is enabled by default and no configuration is required. Asymmetric call leg configuration is also supported: that is, you can have the RPH pass-through configuration on one call leg and RPH to DSCP policing on the another.

AS SIP—Media Bandwidth Policing

In releases prior to Cisco IOS Release 15.2(2)T, Cisco UBE does not support media on a policing per-call basis. Hence, few endpoints negotiate the G729 codec using the SIP offer answer model and send RTP packets with the payload of G711. Few endpoints negotiate with G729 10 ms (one packet per 10 ms) but send two packets as a response to the request of 10 ms. In both cases, more bandwidth than the negotiated bandwidth is used. Cisco UBE has no mechanism to detect bandwidth violation and enforce policing on media policing approaches.

To overcome this problem, the AS SIP—Media Bandwidth Policing feature was introduced in Cisco IOS Release 15.2(2)T. This feature introduces traffic policing on the Cisco UBE to limit media bandwidth usage to the negotiated rate. Excess traffic is dropped when the traffic rate reaches the configured maximum value. The AS SIP—Media Bandwidth Policing feature is supported only on RTP packets.

The AS SIP—Media Bandwidth Policing feature identifies violations in the bandwidth and triggers the following policing actions on additional RTP packets received:

  • Drops all violated packets.

  • Drops all violated packets and disconnects the call once it reaches the configured number of violations.

  • Ignores the violations.

You can enable system log and Simple Network Management Protocol (SNMP) trap generations to inform system administrators about policing violations.

Resource Priority Header

RPH is a SIP header. A SIP request with a RPH is treated as follows:

  • The request is given an elevated priority to access public switched telephone network (PSTN) gateway resources, such as trunk circuits.

  • The request can interrupt lower priority requests at a user terminal, such as an IP phone.

  • The request can carry information from one multilevel priority domain in a telephone network to another, without SIP proxies inspecting or modifying the header field.

  • In SIP proxies and back-to-back user agents, requests of higher priorities can displace the existing signaling requests or bypass the PSTN gateway capacity limits in effect for lower priorities.

This RPH header provides priority and precedence at Layer 7. It is not treated the same way in lower layers.

Differentiated Services Code Point

DSCP or differentiated services code point (DiffServ) is a computer networking architecture that specifies a simple, scalable, and coarse-grained mechanism for classifying and managing network traffic, and providing quality of service (QoS) on modern IP networks.

Applying the DSCP Policing Profile at the Dial Peer Level

Perform this task to apply the DSCP policing profile at the dial peer level.

When the DSCP policing profile is applied to a dial peer and the mode is configured as RPH pass-through, the policy will be enforced if there is any match for the “r-priority” value in the RPH. If there is no match in the namespace, the domain name system (DNS) will be used to match the “r-priority”.

If the RPH pass-through mode is configured, the RPH is passed as it is. The RPH is truncated if the following values are above the specified limits:

  • Only the namespace is changed and there is no change in the subdomain and priority.

  • Maximum namespace allowed is up to ten characters.

  • Maximum subdomains supported range is from 000000 to FFFFFF.

  • Maximum priority values allowed are 24 characters.

Configuration Examples for Configuring DSCP Policing and Media Bandwidth Policing

Example: Configuring the AS SIP—DSCP Policing Feature at the Global Level

The following example shows how to configure the AS SIP—DSCP Policing feature on the Cisco UBE when the incoming invite is an RPH invite: 

Router(config)# voice class dscp-profile 1
Router(config-class)# dscp media audio priority 11
Router(config-class)# dscp media audio flsh af11

Router(config)# voice class dscp-profile 2
Router(config-class)# dscp media audio priority 60
Router(config-class)# dscp media audio flash-override af11

Router(config)# voice class dscp-profile 3
Router(config-class)# violation 10 action disconnect

Router(config)# voice class dscp-profile 4
Router(config-class)# dscp media audio immediate 2
Router(config-class)# dscp media audio flsh 63
Router(config-class)# dscp media audio flash-override af33

Router(config)# voice class dscp-profile 5
Router(config-class)# dscp media audio immediate 1

Example: Applying DSCP Policing

The following example shows how to apply DSCP policing globally and at the dial peer level:


Note

The dial peer configuration will have precedence over the global configuration. 

Router(config)# voice service voip
Router(conf-voi-serv)# sip
Router(conf-serv-sip)# dscp-profile 2

Router(config)# dial-peer voice 1 voip
Router(config-dial-peer)# session protocol sipv2
Router(config-dial-peer)# voice-class sip resource priority dscp-profile 1

Example: Configuring the AS SIP—Media Bandwidth Policing Profile at the Global Level

Router(config)# media profile police 1
Router(cfg-mediaprofile)# violation 20000 action disconnect no-syslog
Router(cfg-mediaprofile)# overhead audio 15

Example: Applying the Media Bandwidth Policing Profile

The following example shows how to apply the media bandwidth policing profile globally and at the dial peer level: 

Router(config)# voice service voip
Router(conf-voi-serv)# media police-profile 1

Router(config)# media class 1
Router(cfg-mediaclass)# police profile 1
Router(cfg-mediaclass)# end
Router# configure terminal
Router(config)# dial-peer voice 4 voip
Router(config-dial-peer)# media-class 1
