SNMP poll of OID "IF-MIB::ifDescr" does not contain interface names after upgrade to R80.40 Technical Level
Symptoms
  • SNMP poll of OID IF-MIB::ifDescr after upgrade to R80.40 Gaia OS shows only the driver details:
    [Expert@GW:0]# snmpwalk -v 2c -c public localhost IF-MIB::ifDescr
    IF-MIB::ifDescr.1 = STRING: lo
    IF-MIB::ifDescr.2 = STRING: VMware VMXNET3 Ethernet Controller
    IF-MIB::ifDescr.3 = STRING: VMware VMXNET3 Ethernet Controller
    IF-MIB::ifDescr.4 = STRING: VMware VMXNET3 Ethernet Controller

  • SNMP poll of OID IF-MIB::ifDescr in a pre R80.40 Gaia OS shows the interface names:
    [Expert@GW:0]# snmpwalk -v 2c -c public localhost IF-MIB::ifDescr
    IF-MIB::ifDescr.1 = STRING: lo
    IF-MIB::ifDescr.2 = STRING: eth0
    IF-MIB::ifDescr.3 = STRING: eth1
    IF-MIB::ifDescr.4 = STRING: eth2
    IF-MIB::ifDescr.5 = STRING: eth3
    IF-MIB::ifDescr.6 = STRING: vpnt1

Cause

The output on R80.40 and higher versions has changed and polling ifDesc provides descriptive information of the interface (Such as driver).
