Overview of Cisco Performance Monitor
Cisco Performance Monitor enables you to monitor the flow of packets in your network and become aware of any issues that might impact the flow before it starts to significantly impact the performance of the application in question. Performance monitoring is especially important for video traffic because high quality interactive video traffic is highly sensitive to network issues. Even minor issues that may not affect other applications can have dramatic effects on video quality.
Because Cisco Performance Monitor uses similar software components and commands as Cisco NetFlow and Cisco Flexible NetFlow, familiarity with these products will help you to understand how to configure Cisco Performance Monitor. These products provide statistics on packets flowing through a router and are the standard for acquiring IP operational data from IP networks. They provide data to support network and security monitoring, network planning, traffic analysis, and IP accounting. For more information about Cisco NetFlow and Cisco Flexible NetFlow, see the documents listed in the Additional References section.
For more information about the design, configuration, and troubleshooting of Performance Monitor and other Cisco Medianet 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.
Prerequisites for Configuring Cisco Performance Monitor
The following prerequisites must be met before you can configure Cisco Performance Monitor:
IPv4 Traffic
- The networking device must be configured for IPv4 routing.
- One of the following must be enabled on your router and on any interfaces on which you want to enable Cisco Performance Monitor: Cisco Express Forwarding or distributed Cisco Express Forwarding.
Limitations for Cisco Performance Monitor
Support for Cisco IOS XE Release 3.3 SG and Cisco IOS release 15.1(1)SG has the following limitations:
- Only ingress monitoring is supported on a Layer 2 Ethernet channelized (LAG) Interface.
- Ingress monitoring is not supported on a Layer 3 Ethernet sub-interface (802.1q).
- Multicast egress monitoring is not supported on a routed interface.
- Egress monitoring is not supported on a switched interface.
- Monitoring is not supported on a virtual access interface
- Monitoring is not supported on a Layer 3 Tunnel (GRE, mGRE, DMVPN) interface.
Configuration Components of Cisco Performance Monitor
To configure Cisco Performance Monitor, configure many of the same basic elements that you normally configure for Flexible NetFlow:
The figure below shows how these elements are related to each other. The elements at the bottom of the figure are configured first.
Figure 1 | Cisco Performance Monitor Components |
As shown above, a policy includes one or more classes. Each class has a flow monitor associated with it, and each flow monitor has a flow record and an optional flow exporter associated with it. These elements are configured in the following order:
- Configure a flow record to specify the key and non-key fields that you want to monitor. This is configured using match and collect commands. You can also optimally configure a flow exporter to specify the export destination. For Cisco Performance Monitor, you must configure a performance-monitortype flow record.
- Configure a flow monitor that includes the flow record and flow exporter. For Cisco Performance Monitor, you must configure a performance-monitortype flow monitor.
- Configure a class to specify the filtering criteria using the class-map command.
- Configure a policy to include one or more classes and one or more performance-monitortype flow monitors using the policy-map command. For Cisco Performance Monitor, you must configure performance-monitortype policies.
- Associate a performance-monitortype policy to the appropriate interface using the service-policy type performance-monitorcommand.
Data That You Can Monitor Using Cisco Performance Monitor

SNMP MIB Support for Cisco Performance Monitor
Cisco Performance Monitor provides support for the use of the industry-standard Simple Network Management Protocol (SNMP) to monitor media streams. This support is implemented with the addition of the following Cisco proprietary SNMP Management Information Base (MIB) modules:
- CISCO-FLOW-MONITOR-TC-MIB--Defines the textual conventions common to the following MIB modules.
- CISCO-FLOW-MONITOR-MIB--Defines the framework that describes the flow monitors supported by a system, the flows that it has learned, and the flow metrics collected for those flows.
- CISCO-RTP-METRICS-MIB--Defines objects that describe the quality metrics collected for RTP streams, similar to those described by an RTCP Receiver Report packet (RFC 3550).
- CISCO-IP-CBR-METRICS-MIB--Defines objects that describe the quality metrics collected for IP streams that have a Constant Bit Rate (CBR).
For detailed information about these MIBs, and to locate and download MIBs for selected platforms, Cisco IOS releases, and feature sets, use Cisco MIB Locator found at http://www.cisco.com/go/mibs .
This feature also includes two new command-line interface (CLI) commands and one modified CLI command. The commands are as follows:
- snmp-server host --Enables the delivery of flow monitoring SNMP notifications to a recipient.
- snmp-server enable traps flowmon --Enables flow monitoring SNMP notifications. By default, flow monitoring SNMP notifications are disabled.
- snmp mib flowmon alarm history --Sets the maximum number of entries maintained by the flow monitor alarm history log.
For more information about these commands, see the Cisco IOS Master Command List .

Configuring a Flow Exporter for Cisco Performance Monitor
Flow exporters are used to send the data that you collect with Cisco Performance Monitor to a remote system such as a NetFlow Collection Engine. Flow exporters use user datagram protocol (UDP) as the transport protocol and use the Version 9 export format.
To configure a flow exporter for the flow monitor, in order to export the data that is collected by Cisco Performance Monitor to a remote system for further analysis and storage, perform the following optional task. For Cisco Performance Monitor, flow exporters are configured the same way as they are configured for Cisco IOS Flexible NetFlow. For more information. see Configuring Data Export for Cisco IOS Flexible NetFlow with Flow Exporters.
Note |
Each flow exporter supports only one destination. If you want to export the data to multiple destinations, you must configure multiple flow exporters and assign them to the flow monitor. |
DETAILED STEPS
Troubleshooting Tips
To check the configuration and status of your flow exporter, use the show flow exportercommand.
Configuring a Flow Record for Cisco Performance Monitor
The basic concepts and techniques for configuring a flow record for Cisco Performance Monitor are the same as flow records for Flexible NetFlow. The flow record specifies how the data collected data is aggregated and presented. The only significant difference is that, for Cisco Performance Monitor, the command includes type performance-monitor.
DETAILED STEPS
Troubleshooting Tips
To check the configuration and status of your flow record, use the show flow record type performance-monitorcommand.
Configuring a Flow Monitor for Cisco Performance Monitor
The basic concepts for configuring a flow monitor for Cisco Performance Monitor are the same as flow monitors for Flexible NetFlow. Each flow monitor has a separate cache assigned to it and requires a record to define the contents and layout of its cache entries.
When you configure a flow monitor, you must use either:
- An existing flow record that you configured
- One of the following default predefined records:
- The default RTP record (default-rtp)
- The default TCP record (default-tcp)
- Flexible NetFlow's "NetFlow IPv4 original input"
Note |
To modify a flow record, you must remove it from all flow monitors it is associated with. > |

This feature enables you to monitor the flow of packets in your network and become aware of any issues that might impact the flow before it starts to significantly impact your applications' performance. Support for this feature was added for Cisco ASR 1000 Series Aggregation Services routers in Cisco IOS XE Release 3.5S. There are some limitations to the monitoring of ingress or egress data on certain types of interfaces for the Cisco IOS XE Release 3.3 SG and Cisco IOS release 15.1(1)SG. For more information, see the "Limitations" section. For all other releases, the following commands were introduced or modified by this feature: action(policy react and policy inline react), alarm severity (policy react and policy inline react), alarm type(policy react and policy inline react), class-map, clock-rate(policy RTP), collect application media, clear fm performance-monitor counters, collect counter, collect flow direction, collect interface, collect ipv4, collect ipv4 destination, collect ipv4 source, collect ipv4 ttl, collect monitor event, collect routing, collect timestamp interval, collect transport event packet-loss counter, collect transport packets, collect transport rtp jitter, debug fm performance-monitor counters, debug performance-monitor counters, description (Performance Monitor), destination dscp (Flexible NetFlow), export-protocol, exporter, flow monitor type performance-monitor, flow record type performance-monitor, flows, history (monitor parameters), interval duration, match access-group, match any, match class-map, match cos, match destination-address mac, match discard-class, match dscp, match flow, match fr-de, match fr-dlci, match input-interface, match ip dscp, match ip precedence, match ip rtp, match ipv4, match ipv4 destination, match ipv4 source, match mpls experimental topmost, match not, match packet length (class-map), match precedence, match protocol, match qos-group, match source-address mac, match transport destination-port, match transport rtp ssrc, match transport source-port, match vlan, max-dropout (policy RTP), max-reorder (policy RTP), min-sequential (policy RTP), monitor metric ip-cbr, monitor metric rtp, monitor parameters, option (Flexible NetFlow), output-features, platform performance-monitor rate-limit, policy-map type performance-monitor, rate layer3, react (policy), record (Performance Monitor), rename (policy), service-policy type performance-monitor, show performance monitor history, show performance monitor status, show platform hardware acl entry interface, show platform software ccm, show platform software feature-manager performance-monitor, show platform software feature-manager tcam, show policy-map type performance-monitor, snmp-server host, snmp-server enable traps flowmon, snmp mib flowmon alarm history , source(Flexible NetFlow), ssrc maximum, template data timeout, threshold value (policy react and policy inline react), timeout (monitor parameters), transport (Flexible NetFlow), and ttl (Flexible NetFlow). |
Cisco Performance Monitor (phase 2) |
15.2(2)T Cisco IOS XE Release 3.5S |
This feature enables you monitor IPv6 fields and also use all other Flexible Netflow collect and match commands not supported in the previous release. Flows are now correlated so that if the same policy is applied on the same input and output interface, the show command will display a single flow for the input and output interfaces. Support for this feature was added for Cisco ASR 1000 Series Aggregation Services routers in Cisco IOS XE Release 3.5S. The following commands were introduced or modified by this feature: collect datalink mac, collect ipv4 fragmentation, collect ipv4 section, collect ipv4 total-length, collect ipv6, collect ipv6 destination, collect ipv6 extensionmap, collect ipv6 fragmentation, collect ipv6 hop-count, collect ipv6 length, collect ipv6 section, collect ipv6 source, collect routing is-multicast, collect routing multicast replication-factor, collect timestamp sys-uptime, collect transport, collect transport icmp ipv4, collect transport icmp ipv6, collect transport tcp, collect transport udp, match application name, match connection transaction-id, match datalink dot1q vlan, match datalink mac, match datalink vlan, match interface, match ipv4 fragmentation, match ipv4 section, match ipv4 total-length, match ipv4 ttl, match ipv6, match ipv6 destination, match ipv6 extension map, match ipv6 fragmentation, match ipv6 hop-limit, match ipv6 length, match ipv6 section, match ipv6 source, match routing, match routing is-multicast, match routing multicast replication-factor, match transport, match transport icmp ipv4, match transport icmp ipv6, match transport tcp, match transport udp |
Cisco Performance Monitor (phase 3) |
