Configuring sFlow Global Parameters
Flow sampling must be enabled globally on the switch, as well as for those ports
where it is required. Due to the switch’s hardware design, flow sampling and the
sampling rate can only be enabled for specific port groups as shown in the following
table. However, sampling for each of the Gigabit ports (25-28/49-52) can be
controlled individually.
Command Usage
• Global Status – Enables sFlow globally for the switch.
• Group/Port Members – The 100BASE-TX ports are organized into groups of 8
based on a restriction in the switch ASIC, and the 4 Gigabit ports each in it’s own
separate group.
• Status – Enables sFlow on the ports in the indicated group.
• Rate – Configures the packet sampling rate. Setting the rate to 0 disables
sampling. Setting the rate to 100 configures sampling to 1 packet out of every 100
received. (Range: 0-10000000; Default: 0)
