Changing the default port for HTTP(s) access to the APIC GUI

  Prerequisites Make sure and have the appropriate Contracts configured for OOB to permit the access to the desired port. If you do not have this in place, the traffic destined to the new port will be killed by the contracts. While not a prerequisite, Since HTTPs access via the GUI is generally the “front … More Changing the default port for HTTP(s) access to the APIC GUI

Using Serial-over-Lan (SOL) on the CIMC to access the APIC (instead of KVM console)

The CIMC is Cisco’s answer to lights-out management for UCS servers, including the UCS servers that house the APICs. For troubleshooting the APIC, most engineers assume you must have direct console (i.e., physical access) or use the Java (or later HTTP)-based KVM Console to get true OOB access to your APIC, however, this is not … More Using Serial-over-Lan (SOL) on the CIMC to access the APIC (instead of KVM console)

Configuring SNMP for ACI

Pre-requisites To allow SNMP communications, you must configure an ‘out-of-band contract’ in ‘mgmt’ tenant allowing SNMP traffic. SNMP traffic typically uses UDP port 161 for SNMP requests. Configure the APIC out-of-band IP addresses in the ‘mgmt’ tenant. Although the out-of-band addresses are configured during APIC setup, the addresses must be explicitly configured in the ‘mgmt’ … More Configuring SNMP for ACI

Creating a backup for your APIC Cluster

One of the main advantages that ACI offers is the ability to simplify the configuration, and the ability to backup, your entire datacenter configuration. In a traditional datacenter network, backups must occur on a box-by-box basis (leading to configuration sprawl), and the process to back them up is generally managed by a combination of network … More Creating a backup for your APIC Cluster
