User Manual

Chapter 3. Commands for sFlow 8

www.qtech.ru

 Usage Guide: If no statistic sampling interval is configured, there will not be any

statistic sampling on the interface.

 Example: Set the statistic sampling interval on the interface e1/0/1 to 20 seconds.

 Switch(Config-If-Ethernet1/0/1)#sflow counter-interval 20

3.4 sflow data-len

 Command: sflow data-len <length-value>

 no sflow data-len

 Function: Configure the max length of the sFlow packet data; the “no sflow data-len”

command restores the default value.

 Parameter: <length-value> is the value of the length with a value range of 500-1470.

 Command Mode: Port Mode.

 Default: The value is 1400 by default.

 Usage Guide: When combining several samples to a sFlow group to be sent, the length

of the group excluding the MAC head and IP head parts should not exceed the

configured value.

 Example: Configure the max length of the sFlow packet data to 1000.

 switch (Config-If-Ethernet1/0/2)#sflow data-len 1000

3.5 sflow destination

 Command: sflow destination <collector-address> [<collector-port>]

 no sflow destination

 Function: Configure the IP address and port number of the host on which the sFlow

analysis software is installed. If the port has been configured with IP address, the port

configuration will be applied, or else the global configuration will be applied. The “no”

form of this command restores the port to default and deletes the IP address.

 Parameter: <collector-address> is the IP address of the analyzer, shown in dotted

decimal notation. <collector-port> is the destination port of the sent sFlow packets.

 Command Mode: Global Mode and Port Mode.

 Default: The destination port of the sFlow packet is defaulted at 6343, and the analyzer

has no default address.

 Usage Guide: If the analyzer address is configured at Port Mode, this IP address and

port configured at Port Mode will be applied when sending the sample packet. Or else

the address and port configured at global mode will be applied. The analyzer address

should be configured to let the sFlow sample proxy work properly.

 Example: Configure the analyzer address and port at global mode.

 switch (config)#sflow destination 192.168.1.200 1025
