APIC-EM Path Trace ACL Analysis Tool

In a previous lesson, I explained how to install APIC-EM and some of its basics. In this lesson, we’ll take a look at the path trace ACL analysis tool which is one of the topics on the blueprint of CCNA R&S.



I will use the following physical topology for this example:

apic em physical lab topology

I used this to build the following logical topology:

apic em logical topology lab

The routers above are running OSPF.  Let’s see if we can trace some traffic.

Configurations

Want to take a look for yourself? Here you will find the startup configuration of each device.

R1

R2

R3

SW1

SW2

In the menu on the left side, select Path Trace:

apic em menu path trace

Select “Start new Path Trace”:

apic em start new path trace

Now we can enter a source and destination. Let’s select R1 as the source:

apic em menu path trace source router

Once you select the device, you can select one of its interfaces. Let’s pick FastEthernet 0/1:

apic em r1 interface fastethernet two

For the destination, we will use R3 and its loopback interface. We will select options and choose TCP as our protocol with destination port 80. For the source port, I’ll pick 50001. Make sure you select ACL trace:

apic em start new path trace acl option

Click on Start Trace and APIC-EM will do its magic. You will see the following screen:
