BIG-IP: How can I get the interface description with SNMP?

Hi,

I've set an individual interface description on a F5 BIG-IP (firmware release BIG-IP 15.1.2.1 Build 0.0.10 Point Release 1) for a physical interface, but when I do a snmpwalk (SNMPv3), I get only the Interface name with a snmp walk.

ich@(lb1)(cfg-sync In Sync)(Active)(/Common)(tmos)# list /net interface 1.8
net interface 1.8 {
  description Testdescription_ADVMON
  disabled

snmpwalk [..]
[..]
IF-MIB::ifDescr.848 = STRING: 1.8
[..]

I have, of course, grepped for the set interface description (Testdescription_ADVMON), but didn't get a hit.

Is it possible to retrieve a customized interface description with SNMP and, if so, how?
