5.21 SFlow function
SFlow is a technology that allows to monitor traffic in packet data networks by partial traffic
selection for the following encapsulation into the special messages sent to the statistics server.
Global configuration mode commands
Command line request in global configuration mode appears as follows:
console(config)#
Table 5.182 —Global configuration mode commands
Command
Value/Default value
Action
sflow receiver id
{ipv4_address | ipv6_address |
ipv6z_address | url} [port port]
[max-datagram-size byte]
id: (1..8);
port: (1..65535)/6343;
byte: positive integer
value /1400;
format:
IPv4: A.B.C.D
IPv6: X:X:X:X::X
IPv6z: X:X:X:X::X%<ID>
Define sflow statistics server address.
- id—sflow server number
- IPv4, IPv6, IPv6z—IP address
- url—host domain name
- port—port number
- byte—maximum quantity of bytes that could be sent in a single
data packet
no sflow receiver id
Delete sflow statistics server address.
Ethernet interface configuration mode commands
Command line request in Ethernet interface configuration mode appears as follows:
console# configure
console(config)# interface {gigabitethernet gi_port| tengigabitethernet
te_port}
console(config-if)#
Table 5.183 —Ethernet interface configuration mode commands
Command
Value/Default value
Action
sflow flow-sampling rate id
[max-header-size bytes]
rate: (0,
1024..107374823);
id: (0..8);
bytes: (20..256)/128
Define the average packet selection rate. Summary selection rate
is calculated as 1/rate*current_speed.
- rate—average packet selection rate
- id—sflow server number
- bytes—maximum quantity of bytes that will be copied from the
packet sample
no sflow flow-sampling
Disable selection counter for the port.
sflow counters-sampling sec id
sec: (0, 15..86400)
seconds;
id: (0..8)
Define the maximum interval between the successful packet
selections.
- sec—maximum interval between selections.
'0' value disables selection
- id—sflow server number (defined by 'sflow receiver' command in
the global configuration mode)
no sflow counters-sampling
Disable selection counter for the port.
