Hello
I use ELK 7.17.
I get data from filebeat netflow and snmp plugin.
I don't know, how i can combine information about interfaces.ifAlias and interfaces.index received from snmp plugin and netflow.egress\_interface and netflow.ingress\_interface received from netflow module filebeat.
I want see description ports in neflow filebeat. How i can do it?
I want see which AS-numbers network/traffic go through certain ports.
Please help me.

Just use [ElastiFlow](https://docs.elastiflow.com/docs/) where all of this stuff has already been done for you. We use this where I work, and I use it for a home lab. The original ElastiFlow used Logstash, but the new version is a custom developed collector. It is much faster than Logstash or Filebeat, but it also has more netflow-specific features.
You can enrich network interfaces using:
1. option records (if supported by your devices) where the device send the mapping of ifIndex to ifName and the ElastiFlow collector uses this to provide the interface name.
2. [SNMP](https://docs.elastiflow.com/docs/config_ref_enrich_netif_snmp)
3. [User-defined](https://docs.elastiflow.com/docs/config_ref_enrich_netif_udm) where you specify the interface name and any other [interface metadata](https://docs.elastiflow.com/docs/config_enrich_netif).
