ACI Useful Commands

We as a network engineers, fall in love with CLI, and it make our life is very easy, from configuring to troubleshoting. and we feel good when see the output of #show run interface eth 1/1 , or #show run router bgp or #show ip route.

and the output of these commands make us understand what is happening and where is the issue.

But the issue with ACI, is everything is GUI, which it makes it alitlle difficult to understand some configurations or where is the issue when configuring EPG and assign it to EP but traffic is not working. So you will need to look for which AP (Application Profile) and which IPG (interface policy group) , etc...

So in the coming articles will focus on show some ACI GUI configuration and its CLI command mapping which will make us understand it well.

So if you need to check which policy configuration is applied to specific interface in GUI, assume we have interface Eth/14 connected to External Network.

Then we need to open the policy group to get the AEP profile

Then we need to open the AEP profile to see which domain is applied to get the VLAN pool.

Now we got the VLAN pool and Domain assigned to:

With CLI:

From APIC it self, we can run the below command:

#Show running-config leaf <No.> interface ethernet <No.>

Another example for port connected to Server:

This port is connected to server, and many EPG is deployed to this interface, So from this output we can get information about:

• Policy Group
• VLANs allowed on the port
• Tenant
• Application Profile and EPG deployed
