Configuring Flow Exports on HP Aruba 2920 Series (J9726A)
The HP 2920 series switches are sFlow capable, but they do not support sFlow while the Out-of-Band-Management (OOBM) port is enabled. Execute the follwoing commands to configure sFlow:
- If you configure sFlow with the OOBM port enabled, no flows will be sent. So, log in from the console port and use the following command to disable OOBM:
no oobm ip address
- Setup the management IP address on a virtual local area network (VLAN), so that the sFlow data can reach Site24x7 with the VLAN of which it's a member of.
vlan 1 ip address 10.100.64.201/21
- Point sFlow to the machine on which Site24x7 On-Premise Poller is installed. The default port is 9996.
sflow 1 destination 10.100.64.135 9996
- Setup the interface you want to pull from, and the sampling and polling rates/intervals. The sampling rate can be 50-16441700. The lower the number, the more packets sampled.
sflow 1 sampling 23 50
sflow 1 polling 23 20
- Do a write memory so that it persists reboots.
