Questions regarding snmp monitoring of peplink

Hi friends,

I’d like to monitor my peplink 20 device using SNMP and for that I did a snmpwalk on it. Looking at the resulting mib i got a little confused with the response I got. Could someone help me out on this?

My pepelink has 4 interfaces (1 LAN, 3 WANS being one of those a GPRS modem). This seems to match this values:

IF-MIB::ifNumber.0 = INTEGER: 4

IF-MIB::ifIndex.1 = INTEGER: 1

IF-MIB::ifIndex.2 = INTEGER: 2

IF-MIB::ifIndex.3 = INTEGER: 3

IF-MIB::ifIndex.4 = INTEGER: 4

IF-MIB::ifDescr.1 = STRING: LAN

IF-MIB::ifDescr.2 = STRING: WAN1

IF-MIB::ifDescr.3 = STRING: WAN2

IF-MIB::ifDescr.4 = STRING: WAN3

now, when I look the ifAdminStatus and ifOperStatus, I got 4 itens on the first bu only 03 of the second.

F-MIB::ifAdminStatus.1 = INTEGER: up(1)

IF-MIB::ifAdminStatus.2 = INTEGER: up(1)

IF-MIB::ifAdminStatus.3 = INTEGER: up(1)

IF-MIB::ifAdminStatus.4 = INTEGER: up(1)

IF-MIB::ifOperStatus.1 = INTEGER: up(1)

IF-MIB::ifOperStatus.2 = INTEGER: up(1)

IF-MIB::ifOperStatus.3 = INTEGER: down(2)

Should’nt be a 4th IF-MIB::ifOperStatus item (IF-MIB::ifOperStatus.4)?

Thanks in advance.

Peplink SNMP does not support on USB interface. Therefore the valid index should be within 1 to 3. The enhancement of SNMP has been put on our roadmap.
