Part 2: How to Verify DNS, NTP, SNMP, Syslog on Cisco ACI APIC CIMC controller

Today we are going to talk about the verification of the DNS, NTP, SNMP, Syslog used in the Cisco ACI APIC. As you guys knew that APIC is a UCS based CIMC controller and we configured DNS, NTP, SNMP, Syslog on the APIC CIMC controller.

What is Cisco ACI APIC?

One of the important pillar of Cisco ACI is APIC which is known as Cisco Application Policy Infrastructure Controller. It is single pane of glass for automation and management for the Cisco ACI fabric, policy enforcement, and health monitoring. It also optimizes performance and manages and operates a scalable multitenant Cisco ACI fabric.

Verification of DNS

Step 1: Log in to the APICs using CIMC.

Step 2: In the Admin TAB click on Networking Menu,

Step 3: In the Network Setting TAB verify DNS server configuration in the IPv4 Properties.

Step 4: Verify whether Dynamic DNS is enabled and the Dynamic DNS Update Domain is configured. (This is the domain name that is appended to a hostname for a Dynamic DNS (DDNS) update. If left blank, only a hostname is sent to the DDNS update request.)

Step 5: As you have multiple CIMC controller for APIC, so you need to repeat these steps for every APIC server.

Verification of NTP

Step 1: As you already login to the CIMC controller, Check the Admin TAB click on Networking Menu.

Step 2:In the NTP Setting TAB verify that NTP is enabled and NTP server are configured.

Step 3: As you have multiple CIMC controller for APIC, so you need to repeat these steps for every APIC server.

Verification of SNMP

Step 1: As you already login to the CIMC controller, Check the Admin TAB click on Communication Services Menu.

Step 2:In the SNMP TAB verify that SNMP configuration and Trap Destinations

Step 3: As you have multiple CIMC controller for APIC, so you need to repeat these steps for every APIC server.

Verification of Syslog

Step 1: As you already login to the CIMC controller, Check the Chassis TAB click on Faults and Logs Menu.

Step 2:In the Logging Controls TAB verify that Remote Syslog Servers are configured.

Step 3: As you have multiple CIMC controller for APIC, so you need to repeat these steps for every APIC server.

Command used for NTP and SNMP

apic01-cimc /cimc/network # exit
apic01-cimc /cimc # scope log
apic01-cimc /cimc/log # show server
apic01-cimc /cimc/log # exit
apic01-cimc /cimc # exit
apic01-cimc# scope snmp
apic01-cimc /snmp # show detail
