This document describes the steps used in order to perform an ELAM on Cisco Nexus 7000 (N7K) M−Series
modules, explains the most relevant outputs, and describes how to interpret the results.

Tip: Refer to the ELAM Overview document for an overview on ELAM.

In this example, a host on VLAN 2500 (10.0.5.101), port Eth4/1 sends an Internet Control Message Protocol
(ICMP) request to a host on VLAN 55 (10.0.3.101), port Eth3/5. ELAM is used in order to capture this single
packet from 10.0.5.101 to 10.0.3.101. It is important to remember that ELAM allows you to capture a single
frame.

In order to perform an ELAM on the N7K, you must first connect to the appropriate module (this requires the
network−admin privilege):

N7K# attach module 4

Attaching to module 4 ...

To exit type 'exit', to abort type '$.'
