ACI SNMP Overview

SNMP is Simple Network Management Protocol which is UDP based network protocol.  The SNMP protocol governs the network management and monitoring of your network devices.

Cisco ACI provides SNMPv1, v2c, and v3 support, including Management Information Bases (MIBs) and notifications (traps). The SNMP standard allows any third-party applications that support the different MIBs to manage and monitor the ACI leaf & spine switches and APIC controllers.

Just wanted to mention that ROOT access can only be granted by a Cisco ACI TAC Engineer and that you will need to work with the Cisco TAC when troubleshooting with ROOT Access. 

The attached PDF is the new revision with updated information.

Hi Experts!


Please help me.

I was confusing that what difference from

    A) FABRIC POLICIES > Monitoring Policies > Common Plicies > Callhome/SNMP/Syslog
    B) FABRIC POLICIES > Monitoring Policies > default > Callhome/SNMP/Syslog
    C) ACCESS PLICIES  > Monitoring Policies > default > Callhome/SNMP/Syslog

Would you tell me A to C difference and Documents.

Regards,
Mot

Fabric policies govern the operation of internal fabric interfaces. The system provides default fabric policies.

DEFAULT POLICY
The monitoring policy model for the DEFAULT policies for the specific infra or tenant scopes.

COMMON POLICY
The monitoring policy model for the common semantic scope, which is used when there is no corresponding policy under the more specific infra or tenant scopes. In such cases, these policies are used throughout the fabric except for objects attached to their own specific policies.

Access policies govern the operation of interfaces that provide external access to the fabric. The system provides default access policies.

DEFAULT POLICY
The monitoring policy model for the DEFAULT policies specific to external access and the policies defined for the infrastructure scopes.
