Interface name

Good day.
Tell me, please, I collect netflow using filebeat.
There are fields
"egress_interface" : 199,
"ingress_interface" : 277,
Through SNMP, I found out which network interfaces correspond to these indexes.
How can I overwrite these values ​​on the described ones?

Perhaps it can be done somehow through
"": [
"eth0" ],
If this is so, please tell me where exactly it is necessary to specify these parameters?
Thank you
