we have a switch A2H124-48P which is not sending snmp traps when a cable is unplugged. I used snmpwalk and found that the O.I.D. .126.96.36.199.188.8.131.52.5.3 is not responding (IF-MIB). This OID is responsible for sending the trap. I have seen in documents that the IF-MIB is supported by A2 series switch but in our case, it is missing. Is there a way to load it on the switch? Is it a matter of firmware?(current version Rev 02.01.10.0001)
The OID you sent is for the trap itself and you can not poll it.
Do you get *any* traps from the switch? If not, you need to check your SNMP configurations.
show snmp notify
show snmp targetaddr
show snmp targetparams
which control the traps.
I am assuming SNMP in general works.
You could try loading "new" code into the switch. I was looking at an A2 with version
03.03.02.0002 which you should be able to download from the Extreme support site.
It will be hiding in the Legacy gear section.
