AVC Configuration

Cisco Application Visibility and Control (AVC) enables detailed monitoring and information gathering from Cisco ASR1K and ISR-G2 routers. It utilizes NBAR2 applications, Application Response Time, QoS hierarchy, and HTTP URL reporting to enhance network visibility.

The Easy Performance Monitor (ezPM) feature introduced in Cisco allows you to configure monitors to export AVC information to external collectors such as ObserveOps (formerly known as AIOps) Flow Explorer. This functionality is available starting from IOS Platform 15.4(1)T and IOS XE Platform 3.10S.

Profiles in Easy Performance Monitor​

Easy performance monitor includes two profiles:

  1. Application Experience
  2. Application Statistics

ObserveOps Flow Explorer displays detailed information based on the Application Experience profile configuration on the device. The Application Experience Profile includes the following monitors:

  • Application Response Time (ART)
  • URL
  • Media
  • Conversation Traffic Stats

Steps to Configure AVC​

Enable the router:

enable

Enter configuration terminal:

configure terminal

Create performance monitor context:

performance monitor context {context-name} profile application-experience

Set exporter destination:

exporter destination {ip address of MOTADATA_NETFLOW Installed Server} source {source interface name} port {UDP port}

[UDP port number by default is 2055 for Motadata ObserveOps]

Configure traffic monitors:

traffic-monitor {application-response-time | conversation-traffic-stats | media [ingress | egress] | url} [ipv4 | ipv6] [sampling-rate number]

To configure additional traffic monitor parameters, repeat this.

Exit performance monitor context:

exit

Select interface to apply configuration:

interface {interface name}

Re-enter performance monitor context:

performance monitor context {context-name}

Exit interface configuration:

exit

Example Configuration​

Below is an example that demonstrates exporting AVC stats from a Cisco ASR1K or ISR G2 router to a server with the IP address 192.168.2.1 and using the source interface GigabitEthernet0/1 to the UDP port 2055:

router>enable 
router#config terminal
router(config)#performance monitor context MOTADATA_NETFLOWAVC profile application-experience 
router( config-perf-mon )# exporter destination 192.168.2.1 source GigabitEthernet0/1 port 2055  
router(config-perf-mon)# traffic-monitor application-response-time ipv4 
router(config-perf-mon)# traffic-monitor conversation-traffic-stats ipv4 
router(config-perf-mon)# traffic-monitor url ipv4 
router(config-perf-mon)# traffic-monitor media ipv4 
router(config)# interface GigabitEthernet0/1
router(config-if)# performance monitor context MOTADATA_NETFLOWAVC

After completing the configuration, navigate to Menu > Flow Explorer and select Explorer to view the active flow data.
