Enables sFlow statistical packet sampling on a particular list of ports.
| port_list | Specifies a list of ports. |
| all | All ports in the system. |
| ingress | Enables ingress sFlow on a per-port basis. |
| egress | Enables egress sFlow on a per-port basis. |
| both | Enables both ingress and egress sFlow on a per-port basis. |
Ingress.
This command enables sFlow on a particular list of ports. Ingress, egress, or a combination of both types of sampling can be enabled on a port. You also need to enable sFlow globally in order to gather statistics and send the data to the collector. Once sFlow is enabled globally, and on the ports of interest, sampling and polling begins.
Use the following command to enable sFlow globally: enable sflow
Note
sFlow and mirroring are not mutually exclusive. You can enable sFlow and mirroring at the same time.For more information about mirroring, see Configuring Slots and Ports on a Switch.
The following command enables egress sFlow sampling on the port 3:1:
enable sflow ports 3:1 egress
This command was first available in ExtremeXOS 11.0.
The ingress, egress, and both keywords we added in ExtremeXOS 15.4.
This command is available on ExtremeSwitching 5320, 5420, 5520, and 5720 series switches.
