Configuring sFlow (CLI)
The following sFlow commands allow you to configure sFlow instances via the CLI. For more information, see Advanced management: RMON.
Syntax:
[no] sflow <receiver-instance> destination <ip-address> [< udp-port-num >]
Enables an sFlow receiver/destination. The receiver-instance number must be a 1, 2, or 3.
By default, the udp destination port number is 6343.
To disable an sFlow receiver/destination, enter no sflow receiver-instance
.
Syntax:
sflow <receiver-instance> sampling <port-list> <sampling rate>
Once an sFlow receiver/destination has been enabled, this command enables flow sampling for that instance. The receiver-instance number is 1, 2, or 3, and the sampling rate is the allowable non-zero skipcount for the specified port or ports.
To disable flow-sampling for the specified port-list,
repeat the above command with a sampling rate of 0
.
Syntax:
sflow <receiver-instance> polling <port-list> <polling interval>
Once an sFlow receiver/destination has been enabled, this command enables counter polling for that instance. The receiver-instance number is 1, 2, or 3, and the polling interval may be set to an allowable non-zero value to enable polling on the specified port or ports.
To disable counter-polling for the specified
port-list, repeat the above command with a polling interval of 0
.
Under the multiple instance implementation, sFlow can be configured via the CLI or via SNMP. However,
CLI-owned sFlow configurations cannot be modified via SNMP, whereas
SNMP-owned instances can be disabled via the CLI using the no sflow <receiver-instance>
command.
