net-snmp - customize snmpd

Hello,

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 ?

My first step is to understand how to "convince" snmpd that the switch has 16 ports.
The default is 4 which is the number if etherent devices in the x86. This is of course not relevant for my needs.

Thank you,
Zvika

snmp on a standard Linux host can be extended through shell scripts to perform any kind of checks. You could write extensions that make use of the linux/device library to query your device and report it back to your snmp client. These checks will be on a different OID but can then be set up as services in your monitoring software accordingly.

Look for the section "Executables/scripts" in snmpd.conf that should give details on extending snmpd with scripts and also shows the OID "entry point"
