IPv4

Configure the devices for IPv4 routing.

UDP port 9995

Configure the devices to send data from Cisco IOS Flexible NetFlow directly to UDP port 9995 on the collector. Do not include the devices in a SPAN.

Collection interval

UC Monitor supports a collection interval of 60 seconds or less. We recommend an interval of 15 or 30 seconds. Such an interval helps ensure correct correlation of data and accurate start and end times.

To configure the duration of the collection interval for a Performance Monitor policy, use the interval duration command in monitor parameters configuration mode.

Flow Exporter

In the Flow Exporter configuration, set the export destination (the collector) and the SNMP index-to-name mapping.

• To configure the destination for a Performance Monitor Exporter, use the destination command in config-flow-exporter configuration mode.
• To configure the interface-table option for a Performance Monitor Exporter, use the option command in config-flow-exporter configuration mode.

Flow Monitor

Create a Flow Monitor record that includes at least the following collect and match Performance Monitor commands:

• match ipv4 protocol
• match ipv4 source address
• match ipv4 destination address
• match transport source-port
• match transport destination-port
• match transport rtp ssrc
• collect ipv4 dscp
• collect ipv4 ttl
• collect transport packets lost counter
• collect transport packets out-of-order (*)
• collect transport rtp jitter mean
• collect transport rtp jitter maximum
• collect transport rtp payload-type (*)
• collect interface input
• collect interface output
• collect application media packets counter
• collect application media packets rate

(*) Requires Cisco IOS release 15.2 or later.
