SNMP Polling against APIC not working

[julian.bendix]

Hey Folks,

I hope somebody has further insight on my issue here.
I am trying to monitor my ACI fabric via SNMP Polling (against the OOB IP addresses).
Tried this running earlier 4.2(2f) and now 4.2(3j).

What I already did and already works:

Under Fabric > Fabric Policies > Pods I added an new Policy Group allowing my SNMP Clients (also referenced the mgmt-EPG) and using my Community-String, then I referenced the Policy Group under the Default Pod Profile.
Then I also verified under Tenant > mgmt Tenant > Contract > Out-Of-Band Contract that SNMP is allowed.

Now polling all kind of info works perfectly fine from the Leaf and Spine Switches,
but the APIC does not respond to anything... 

Polling against OOB IPs in all cases.

Does anyone have another idea on that?

Thanks a lot in advance
Juls

Are the APICs part of the EPG to which the OOB contract is applied?  By default, the APICs are not not part of any management EPG; in this scenario, some baseline services, such HTTPS and SSH are permitted, however SNMP is one of the protocols that is dropped without an explicit contract.

@Timothy Rothenberg that was it, yes!

APIC wasn't part of the correct oob-mgmt-egp.
I feel stupid :)

Thanks a lot man!

Best regards

Hi Julian,

I was having a similar issue.  The big gotchas are ensuring you have APIC IPs specified in the mgmt tenant under "Node Management Addresses" and that you have a contract applied.  I had everything configured but was missing the contract on the mgmt tenant. 

I found the following videos which should help:

Hi Julian,

By defaullt,Apic is not supporting SNMP config like leaf and spine.

In order receive the SNMP polling,we have to configure MIB vlaues,which is available in the below docuement.
