Hi all,

I have a system with a nios2 and a network interface (Altera Triple speed Ethernet MAC).

I use 2.6.30 kernel on my board and net-snmp 5.2.1.

I can see my network interfaces using ifconfig :

--- Quote Start ---

/# ifconfig

eth0 Link encap:Ethernet HWaddr 00:15:12:00:15:88

inet addr:192.168.0.110 Bcast:192.168.0.255 Mask:255.255.255.0

So the systems know interface statistics.

But I wonder why net-snmp is not able to handle these statistics automatically.

I have the following :

So it is ok for the system mibs and some other infos, but nothing about my network interface (eth0)...

My (simple) config :

--- Quote Start ---

rwcommunity private

rocommunity public

sysServices 2

sysDescr XXX

interface eth0 6 100000000

--- Quote End ---

As you can see I tried to add "interface eth0 6 100000000" to my conf file but it is not recognized by this version of net-snmp

I can't figure out if net-snmp is able to "automatically" retrieve network interface, or if my issue is related to the nios2 linux environment I use. I googled a lot for nothing.

Do I need to add a MIB in menuconfig (I tried mibII/ifTable mibII/interface mibII Rmon if-mib...) ?

Do you have any idea ?

Thanks
