We do need a couple of things set up before SNMP will workL
- An out-of-band contract in the mgmt tenancy, permitting SNMP traffic (UDP/161). This should already be set up as part of the Using Contracts between Tenants recipe from Chapter 2, Configuring Policies and Tenants.
- APIC out-of-band IP addresses to be configured in the mgmt tenant. While these IP addresses are configured during the initial setup, they must be explicitly set for the OOB contract to take effect. Refer to the Switch Diagnostics recipe in Chapter 9, Troubleshooting ACI, for how to set this up.
