7 (Optional) Select a destination from the right-hand column and click << to remove the destination from
the port mirroring session.

Configure NetFlow Settings
NetFlow is a network analysis tool that you can use to monitor network monitoring and virtual machine
traffic.
NetFlow is available on vSphere distributed switch version 5.0.0 and later.
Prerequisites
Launch the vSphere Client and log in to a vCenter Server system.
Procedure
1 Log in to the vSphere Client and select the Networking inventory view.
2 Right-click the vSphere distributed switch in the inventory pane, and select Edit Settings.
3 Navigate to the NetFlow tab.
4 Type the IP address and Port of the NetFlow collector.
5 Type the VDS IP address.
With an IP address to the vSphere distributed switch, the NetFlow collector can interact with the
vSphere distributed switch as a single switch, rather than interacting with a separate, unrelated switch
for each associated host.
6 (Optional) Use the up and down menu arrows to set the Active flow export timeout and Idle flow
export timeout.
7 (Optional) Use the up and down menu arrows to set the Sampling rate.
The sampling rate determines what portion of data NetFlow collects, with the sampling rate number
determining how often NetFlow collects the packets. A collector with a sampling rate of 2 collects data
from every other packet. A collector with a sampling rate of 5 collects data from every fifth packet.
8 (Optional) Select Process internal flows only to collect data only on network activity between virtual
machines on the same host.
9 Click OK.
Switch Discovery Protocol
Switch discovery protocols help vSphere administrators to determine which port of the physical switch is
connected to a vSphere standard switch or vSphere distributed switch.
vSphere 5.0 and later supports Cisco Discovery Protocol (CDP) and Link Layer Discovery Protocol (LLDP).
CDP is available for vSphere standard switches and vSphere distributed switches connected to Cisco
physical switches. LLDP is available for vSphere distributed switches version 5.0.0 and later.
When CDP or LLDP is enabled for a particular vSphere distributed switch or vSphere standard switch, you
can view properties of the peer physical switch such as device ID, software version, and timeout from the
vSphere Web Client.
