## IOAM Analyser for IPv6 {#ioam_analyser_doc}
IOAM Analyser for IPv6 does
- Analysing iOAM records and aggregating statistics
- Export the aggregated statistics over IP-FIX to external collector.
Following statistics are collected and exported per IOAM flow:
- All the Paths available for the flow : Collected using IOAM Trace.
- Delay
- POT data: No of packets In Policy and Out of Policy.
- Packet loss count
- Reordered Packet count
- Duplicate Packet count
This feature can work on IOAM decapsulating node or as a standalone external analyser.
## Configuration
Below command can be used to configure a VPP node as IOAM analyser:
set ioam analyse [export-ipfix-collector] [disable] [listen-ipfix]
- export-ipfix-collector : This keyword instructs VPP to export the IOAM
analysis data to be exported to an external collector via IP-Fix. Note
that IP-Fix collector information has to be configured using the below
command:
set ipfix exporter collector <Remote IP Address> src <Local IP address>
- listen-ipfix : This keyword instructs VPP node to listen to IP-Fix port
4739 to receive RAW IOAM records exported by using IOAM Export plugin and
analyse IOAM records.
- disable : This keyword is used to instruct VPP to stop analysing IOAM.
Example1 : To use VPP as IOAM Analyser on IOAM decapsulating node and export.
set ipam analyse export-ipfix-collector
set ipfix exporter collector 172.16.1.254 src 172.16.1.229
Above commands when configured on a IOAM Decapsulating node will analyse
all the IOAM data before Decap, aggregate statistics and export them to
node with IP address 172.16.1.254 via IP-Fix.
Example2 : To use VPP as a standalone IOAM Analyser and export.
set ipam analyse export-ipfix-collector listen-ipfix
set ipfix exporter collector 172.16.1.254 src 172.16.1.229
Above commands when configured on a VPP node will listen on IP-Fix
port 4739 for IP-Fix records containing IOAM Raw data aggregate
statistics and export them to node with IP address 172.16.1.254 via IP-Fix.
## Operational data
For checking the operational data of VPP IOAM analyser below command needs to be used:
show ioam analyse
Example:
vpp# show ioam analyse
