ESXi 5.5: Enhanced Host-Level Packet Capture

Can anyone explain how to use this new feature?

Enhanced Host-Level Packet Capture

Troubleshooting any network issue requires various sets of tools. In the vSphere environment, the VDS

provides standard monitoring and troubleshooting tools, including NetFlow, Switched Port Analyzer (SPAN),

Remote Switched Port Analyzer (RSPAN) and Encapsulated Remote Switched Port Analyzer (ERSPAN). In this

release, an enhanced host-level packet capture tool is introduced. The packet capture tool is equivalent to the

command-line tcpdump tool available on the Linux platform.

The following are some of the key capabilities of the packet capture tool:

• Available as part of the vSphere platform and can be accessed through the vSphere host command prompt

• Can capture traffic on VSS and VDS

• Captures packets at the following levels

––Uplink

––Virtual switch port

––vNIC

• Can capture dropped packets

• Can trace the path of a packet with time stamp details

Couldn't find any documentation for this tool and tcpdump-uw is exactly the same as in 5.1.
