I think your problem is that you are trying to apply three different views
group to that view.
Post by Murali KaricheriHi, Users,
Post by Murali KaricheriDoes Linux support if-mib (new version of ifTable) or do we have to use
old version (mibII/interfaces?
Post by Murali KaricheriFrom the README.agent-mibs, I gather the following:-
IF-MIB
ifNumber.0 U $2 ~3.2 O mibII/interfaces.c
ifTableLastChange.0 ---
ifTable (old) U $2 ~3.5 O mibII/interfaces.c
ifTable (new) L 5.2 M if-mib/ifTable/*
ifTable (new) FOS 5.4 M if-mib/ifTable/*
ifXTable L 5.2 M if-mib/ifXTable/*
ifXTable FOS 5.4 M if-mib/ifXTable/*
ifStackLastChange.0 ---
ifStackTable ---
ifTestTable ---
ifRcvAddressTable ---
So it looks like ifTable (new) and ifXTable are supported in Linux. Also by running
the net-snmp manually using -Dmib_init -H, I can see IF-MIB is getting loaded.
Some reason, a query to the target from a Linux PC returns me no MIB. I see following
logs at the Linux PC:-
snmpwalk -v 2c -c public <IP address of target board> interfaces 2>/dev/null
IF-MIB::interfaces = No more variables left in this MIB View (It is past
the end of the MIB tree)
At the target I invoked snmpd with -d option to see the packets coming in and going out as
below. Also made sure the ifTable and ifXTable MIBs are loaded. Do you know what else is
missing to allow querying IF-MIB..
Also updated the /etc/snmp/snmpd.conf to enable access to the specific MIBs as below. I am
assuming my snmpd.conf is not setup properly to allow this query to go through, but I can't
figure what is wrong. I appreciate any suggestions to get this functional on my board.
Here is my /etc/snmp/snmpd.conf

Here is the hex dump of messages for the query.
