Re: snmpd.conf : interface group

Hi Jeroen,

My x86 is connected via PCIe to an Intel's device. This device(ASIC)
is an ethernet switch (fm10k)
Intel provides a linux library + device driver for managing the switch
(e.g: read port status, set port speed).
I want to run snmpd on the x86 and fill the TODO with the relevant Intel's API.

Intel does not provide any SNMP infrastructure for this device.

I think it will be great if the x86 will run snmpd with some
customization and will monitor\manage the switch device.
Is it possible ?

What SNMP agent runs in all commercial switches. Is it not snmpd ?

Thank you,
Zvika
