This document describes the steps used in order to perform an ELAM on a Cisco Nexus 7000 (N7K) F1
module, 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 10 (10.1.1.101 with MAC address 0050.56a1.1a01), port Eth3/18 sends an
Internet Control Message Protocol (ICMP) request to a host that is also on VLAN 10 (10.1.1.102 with MAC
address 0050.56a1.1aef), port Eth3/26. ELAM is used in order to capture this single frame from 10.1.1.101 to
10.1.1.102. It is important to remember that ELAM allows you to capture only 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 3

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