Brocade Communications Systems 6650 manual Configuring and enabling sFlow, SFlow and source port

sFlow 11

NOTE

The device uses the router ID only if the device also has an IP interface with the same address. Router ID is not supported on IPv6 devices.

NOTE

If an IP address is not already configured when you enable sFlow, the feature uses the source address 0.0.0.0. To display the agent_address, enable sFlow, then enter the show sflow command. Refer to “Enabling sFlow forwarding” on page 263 and “Displaying sFlow information” on page 267.

NOTE

In sFlow version 5, you can set an arbitrary IPv4 or IPv6 address as the sFlow agent IP address. Refer to “Specifying the sFlow agent IP address” on page 265.

sFlow and source port

By default, sFlow sends data to the collector out of UDP source port 8888, but you can specify a different source port. For more information, refer to “Changing the sFlow source port” on page 263.

sFlow and sampling rate

The sampling rate is the average ratio of the number of packets incoming on an sFlow enabled port, to the number of flow samples taken from those packets. sFlow sampling can affect performance in some configurations.

Note that on the Brocade ICX 6650 devices, the configured sampling rate and the actual rate are the same. The software does not adjust the configured sampling rate as on other Brocade devices.

Configuring and enabling sFlow

NOTE

The commands in this section apply to sFlow version 2 and sFlow version 5. CLI commands that are specific to sFlow version 5 are documented in “sFlow version 5 feature configuration” on page 264.

To configure sFlow, perform the following tasks:

•Optional – If your device supports sFlow version 5, change the version used for exporting sFlow data

•Specify collector information. The collector is the external device to which you are exporting the sFlow data. You can specify up to four collectors.

•Optional – Change the polling interval

•Optional – Change the sampling rate

•Optional – Change the sFlow source port

•Enable sFlow globally

•Enable sFlow forwarding on individual interfaces

•Enable sFlow forwarding on individual trunk ports

•If your device supports sFlow version 5, configure sFlow version 5 features
