Configuring for Network Management Applications
Using SNMP Tools To Manage the Switch
Configuring sFlow
The following sFlow commands allow you to configure sFlow instances via
the CLI.
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”.
N o t e Under the multiple instance implementation, sFlow can be configured via the
CLI or via SNMP. However, CLI-owned sFlow configurations cannot be modi­
fied via SNMP, whereas SNMP-owned instances can be disabled via the CLI
using the
no sflow <receiver-instance> command.
Viewing sFlow Configuration and Status
The following sFlow commands allow you to display sFlow configuration and
status via the CLI.
Syntax: show sflow agent
Displays sFlow agent information. The agent address is normally the ip address of
the first vlan configured.
Syntax: show sflow <receiver instance> destination
Displays information about the management station to which the sFlow sampling-
polling data is sent.
Syntax: show sflow <receiver instance> sampling-polling <port-list/range>
Displays status information about sFlow sampling and polling.
