Changing the sFlow source port
By default, sFlow sends data to the collector using UDP source port 8888, but you can change the
source UDP port to any port number in the range 1025-65535.
To change the source UDP port, enter a command such as the following:
Brocade(config)#sflow source-port 8000
Syntax: [no] sflow source-port <num>
The <num> parameter specifies the sFlow source port.
Enabling sFlow forwarding
sFlow exports data only for the interfaces on which you enable sFlow forwarding. You can enable
sFlow forwarding on Ethernet interfaces.
To enable sFlow forwarding, perform the following:
• Globally enable the sFlow feature
• Enable sFlow forwarding on individual interfaces
• Enable sFlow forwarding on individual trunk ports
NOTE
Before you enable sFlow, make sure the device has an IP address that sFlow can use as its source
address. Refer to “sFlow and source address” on page 256 for the source address requirements.
NOTE
When you enable sFlow forwarding on an 802.1X-enabled interface, the samples taken from the
interface include the username used to obtain access to either or both the inbound and outbound
ports, if that information is available. For information about 802.1X, refer to the Brocade ICX 6650
Switch Security Configuration Guide.
Command syntax for enabling sFlow forwarding
This section shows how to enable sFlow forwarding.
Globally enabling sFlow forwarding
To enable sFlow forwarding, you must first enable it on a global basis, then on individual interfaces
or trunk ports, or both.
To globally enable sFlow forwarding, enter the following command.
Brocade(config)#sflow enable
You can now enable sFlow forwarding on individual ports as described in the next two sections.
Syntax: [no] sflow enable
Enabling sFlow forwarding on individual interfaces
To enable sFlow forwarding enter commands such as the following.
