Configuring sFlow on HP Aruba 2920 (J9726A)

This document provides instructions on configuring sFlow on the HP 2920 series switches, which are capable of sFlow but require the Out-of-Band Management (OOBM) port to be disabled for successful operation.

Configuration Steps

Disable the OOBM port:

no oobm ip address

Setup the management IP address on a VLAN:

vlan 1 ip address {YOUR_VLAN_IP/SUBNET}

Point sFlow to your MFE collector server:

sflow 1 destination {MOTADATA_COLLECTOR_IP} 2055

Setup the interface you want to pull from, and configure the sampling and polling rates:

sflow 1 sampling 23 50
sflow 1 polling 23 20

Save the configuration to ensure it persists across reboots:

write memory

After completing the configuration, navigate to Menu > Flow Explorer and select the Event Source(s) and the associated Interface(s) from the drop-downs to view the active flow data.
