I have enabled network interface disaggregation using 'interface' and I can now see 8 new interfaces e.g. (tcp://*:5556c [If Idx: 9]), (tcp://*:5556c [If Idx: 10]) etc

I'd like to change the custom name to something more readable, e.g, rtr01-port7, is there a way to understand what e.g. ldx:9 relates to in relation to the real router interfaces so I can rename appropriately?

Cheers

Mark

Hi,

Interface ids are used by the router to uniquely identify its interfaces. Human-readable names (e.g., port7) can be associated to these ids.

You can get id-to-name associations from the CLI of your router of via SNMP for example.

Via SNMP you can walk the IF-MIB as follow:

[simone@develv5 ntopng]$ snmpwalk -v2c -c XXXXX 192.168.2.1 ifName
IF-MIB::ifName.1 = STRING: lo
IF-MIB::ifName.2 = STRING: eth0
IF-MIB::ifName.3 = STRING: eth1
IF-MIB::ifName.4 = STRING: eth2
IF-MIB::ifName.5 = STRING: imq0


Response is

IF-MIB::ifName.<ID> = STRING: <NAME>
