Configuring Cisco Mediatrace

This chapter contains information about and instructions for configuring Cisco Mediatrace.

Cisco Mediatrace enables you to isolate and troubleshoot network degradation problems for data streams. Although it can be used to monitor any type of flow, it is primary used with video flows. It can also be used for non-flow related monitoring along a media flow path.

Information About Configuring Cisco Mediatrace

Overview of Cisco Mediatrace


Note


Mediatrace is no longer supported on M&T train. For performance monitoring, see Configuring Cisco Performance Monitor chapter.


Cisco Mediatrace helps to isolate and troubleshoot network degradation problems by enabling a network administrator to discover an IP flow’s path, dynamically enable monitoring capabilities on the nodes along the path, and collect information on a hop-by-hop basis. This information includes, among other things, flow statistics, and utilization information for incoming and outgoing interfaces, CPUs, and memory, as well as any changes to IP routes or the Cisco Mediatrace monitoring state.

This information can be retrieved in either of two ways:

  • By issuing an exec command to perform an on-demand collection of statistics from the hops along a media flow. During this one-shot operation, the hops along the media flow are discovered and shown to you, along with a set of other specified information.

  • By configuring Cisco Mediatrace to start a recurring monitoring session at a specific time and on specific days. The session can be configured to specify which metrics to collect, and how frequently they are collected. The hops along the path are automatically discovered as part of the operation.

After collecting the metrics you specified, you can view a report on the metrics.

Cisco Mediatrace is part of the Cisco Medianet family of products. For more information about the design, configuration, and troubleshooting of Mediatrace when used in conjunction with other Cisco products, including a Quick Start Guide and Deployment Guide, see the Cisco Medianet Knowledge Base Portal, located at http://www.cisco.com/web/solutions/medianet/knowledgebase/index.html.

Overview of Configuring Cisco Mediatrace

Information can be retrieved from Mediatrace by using in either:

  • A pre-scheduled, recurring monitoring session.

  • An one-shot, on-demand collection of statistics, known as a Mediatrace poll.

Before you can implement a Mediatrace session or poll, you enable Mediatrace on each network node that you want to collect flow information from. You must enable the Mediatrace Initiator on the network node that you will use to configure, initiate, and control the Mediatrace sessions or polls. On each of the network nodes that you want top collect information from, you must enable the Mediatrace Responder.

To configure a Cisco Mediatrace session, you can set session parameters by associating either of two types of pre-packaged profiles with the session:

  • video-monitoring profiles

  • system-data profiles

You can also configure your own parameters for a Cisco Mediatrace session by configuring the following types of profiles and associating them with the session:

  • Path-specifier profile

  • Flow-specifier profile

  • Sessions-parameters profile

Therefore, the next section describes how to perform the following tasks in order to configure a Cisco Mediatrace session:

  1. Enable mediatrace

  2. Setup a video-monitoring profile

  3. Setup a system-data profile

  4. Setup a path-specifier profile

  5. Setup a flow-specifier profile

  6. Setup a sessions-params profile

  7. Associate profiles with a mediatrace session

  8. Schedule a mediatrace session

The next section also describes how to execute a mediatrace poll, which is an on-demand fetch of data from the hops on a specific path.

In addition, the next section describes how to manage mediatrace sessions by performing the following tasks:

  • Clear incomplete Cisco Mediatrace sessions

  • Troubleshoot a Cisco Mediatrace session

Limitations

  • Mediatrace does not support IPv6.
  • Resource Reservation Protocol (RSVP) does not forward an incoming Path message on the same interface (i.e., through the interface from where it receives the path message). It displays an error some message on the console, “ingress interface = egress interface”. But the Path is sent out on the incoming interface in case of an Performance Routing (PfR) border router.

Executing a Cisco Mediatrace Poll

Cisco Mediatrace polls are used to perform an on-demand fetch of data from the hops on a specific path. Some examples of how it can be used are:

  • To retrieve data using a pre-configured session. In this case, no other parameters have to be specified inline. The pre-configured session must be have the frequency type set to on-demand.

  • To retrieve the system data, hop or video monitoring information from hops along the specified path. You can specify the path as a pre-configured path-specifier or an inline path specification, in case you do not have config mode privileges. Note that by default, Cisco Mediatrace tries to configure nodes along the path to report passive monitoring metrics, and then waits for a configurable amount of time before going out again to collect the data.

  • The configless keyword can be used to fetch data from the nodes along a media path, which already have Performance Monitor policies configured using the Performance Monitor commands. Some key things to keep in mind when fetching data using this method are that:
    • The default perf-monitor profile or associated perf-monitor profile will have a sampling interval. If the sampling interval of the static policy does not match the one in the associated perf-monitor profile, no data is returned.
    • If there is no Performance Monitor policy configured on a Responder node, the Cisco Mediatrace responder does not try to configure Performance Monitor and simply reports error to the initiator.

SUMMARY STEPS

  1. enable
  2. mediatrace poll {no-traceroute | session number | [timeout value ] path-specifier {name path-name | gsid gsid | {[disc-proto rsvp ] destination ip ip-address [port nnnnn ] | source ip ip-address [port nnnnn ] destination ip ip-address [port nnnn ] [ip-protocol {tcp | udp }]} {app-health | hops | l2-params gateway ip-address | system [profile system-profile-name ] | [configless ] perf-monitor [profile profile-name ]} {flow-specifier name | source-ip ipaddress [source-port nnnnn ] dest-ip ipaddress [dest-port nnnnn ] ip-protocol {tcp | udp }}}}
  3. end

Examples


Tip


For examples of poll output, see Configuration Examples for Cisco Mediatrace.


The following example shows how to fetch the default system metrics when the source IP address, source port, and destination port are not known. Cisco Mediatrace uses the best local IP address as source IP address to find which hops are using RSVP.

mediatrace poll path dest ip-address system

The following example shows how to fetch the default system metrics when the source and destination port numbers are not known. RSVP finds the hop between the specified source and destination.

mediatrace poll path source ip-address dest ip-address system

The following example shows how to fetch the default system metrics when the source and destination port numbers are known. RSVP finds the hop using this information.

mediatrace poll path source-ip ip-address source - port nnnn dest-ip ip-address dest - port nnnn ip-protocol udp system

The following example shows how to fetch the default set of RTP metrics when the source and destination port numbers are not known. Cisco Mediatrace uses the path source and destination IP addresses to find the hops as well as filter the Performance Monitor data.

mediatrace poll path source ip-address dest ip-address perf-monitor

The following example shows how to fetch the default set of RTP metrics. Cisco Mediatrace uses the path parameters to discover hops and uses the inline flow specifier profile as a filter for Performance Monitor data.

mediatrace poll path source ip-address dest ip-address perf-monitor source-ip ip-address source - port nnnn dest-ip ip-address dest - port nnnn ip-protocol udp

The following example shows how to fetch the default set of TCP metrics. Cisco Mediatrace uses the path parameters to discover hops and uses the inline flow-specifier profile as a filter for Performance Monitor data.

mediatrace poll path source ip-address dest ip-address perf-monitor source-ip ip-address source - port nnnn dest-ip ip-address dest - port nnnn ip-protocol tcp

The following example shows how to fetch the default set of RTP metrics. Cisco Mediatrace uses the best local IP address as source IP address for finding hops on the path and uses the inline flow specifier profile as a filter for Performance Monitor data.

mediatrace poll path dest ip-address perf-monitor source-ip ip-address source - port nnnn dest-ip ip-address dest - port nnnn ip-protocol udp

The following example shows how to fetch the default set of TCP metrics. Cisco Mediatrace uses the best local IP address as source IP address for finding hops on the path and uses the inline flow-specifier profile as a filter for Performance Monitor data.

mediatrace poll path dest ip-address perf-monitor source-ip ip-address source - port nnnn dest-ip ip-address dest - port nnnn ip-protocol tcp

The following example shows how to fetch the default set of RTP metrics from the static policy that is already configured on the hops. The command does not configure the Performance Monitor. Cisco Mediatrace uses the path parameters to discover hops and use the inline flow specifier profile as a filter for Performance Monitor data.

mediatrace poll path source ip-address dest ip-address configless perf-monitor flow-specifier source ip-address port nnnn dest ip-address port nnnn ip-protocol udp

Configuration Examples for Cisco Mediatrace

Example Basic Mediatrace Configuration

The topology for this example includes:

  • One mediatrace initiator (10.10.12.2)

  • Two mediatrace responders between:
    • A media source (10.10.130.2)
    • A destination (10.10.132.2)

In this example, there is an RTP traffic stream from the source (address=10.10.130.2, port=1000, to the destination (address=10.10.132.2, port=2000).

The basic configuration of the mediatrace responder is as follows:


mediatrace responder
snmp-server community public RO

The basic configuration of the mediatrace initiator is as follows:


mediatrace initiator source-ip 10.10.12.2
mediatrace profile system intf1
mediatrace profile perf-monitor rtp1
mediatrace path-specifier path1 destination ip 10.10.132.2 port 2000
 source ip 10.10.130.2 port 1000
mediatrace flow-specifier flow1
 source-ip 10.10.130.2 source-port 1000
 dest-ip 10.10.132.2 dest-port 2000
mediatrace session-params sp1
