In this example a host on Vlan10 (10.1.1.101) port Eth6/4 sends an ICMP request to a host also on Vlan10 (10.1.1.102) off port Eth6/3.  We will use ELAM to capture this single packet between the hosts.  It’s important to remember that ELAM allows us to capture a single frame. To perform an ELAM on  Full Article…

ELAM (Embedded Logic Analyzer Module) is an engineering tool that gives us the ability to look inside Cisco ASICs and understand how a packet is being forwarded.  ELAM is “embedded” within the forwarding pipeline and can capture a packet in real time without affecting performance or control plane resources.  It can help answer questions like:  Full Article…
