sflow source-interface

Syntax

sflow source-interface { ethernet slot/port | loopback loopback_num | management mgmt-id | ve ve_interface }

no sflow source-interface

By default, sFlow uses the management port IP address as the source IP.

ethernet slot/port: Specifies an Ethernet slot and port. The only supported slot value on the fixed form factor SLX devices is 0.
loopback loopback_num: Specifies a loopback interface. Valid values range from 1 through 255.
management mgmt-id: Specifies the management interface. The only supported value is 0.
ve ve-interface-number: Specifies a virtual Ethernet (VE) interface. Valid values range from 1 through 4096.

Global configuration mode

The no form of the command is available after the source type has been specified.

The sFlow source IP (source interface) configurations are not applicable to sFlow collectors that are reachable through the management port unless the specified source interface falls in the management VRF.
The show sflow command displays the source interface field only when it is configured.

To specify the Ethernet address as the source of sFlow packets:

device# config
device(config)# sflow source-interface ethernet 0/1

To specify the loopback interface as the source of sFlow packets:

device(config)# sflow source-interface loopback 42

To confirm the above configuration:

device(config)# do show running-config sflow
sflow enable
sflow source-interface loopback 42

To disable the above configuration and revert to the default:

device(config)# no sflow source-interface
device(config)# do show running-config sflow
sflow enable
