- "moo.company.com" is the "
iperfserver" - "cow.company.com" is the "
iperfclient"
1. Log in to the first Avamar grid (the "iperf server") as admin, and run the following command:
iperf3 -s -i 1
2. Leave the command above running.
3. Log in to the second Avamar grid as (the "iperf client") admin, and run the following command:
iperf3 -c <avamar-source-iperf-server> A -i 1
4. Let the command run for 10 seconds, then end with a CTRL-C.
Example output seen on "avamar-moo.company.com": (the "iperf server"):
admin@avamar-moo:~/>: iperf3 -s -i 1

Ďalšie informácie
When running the tests on Avamar, the connection attempt may time out if the firewall (avfirewall) service is running:
admin@ave-cow:~/>: iperf3 -c ave-moo -i 1
connect failed: Connection timed out
If this occurs, temporarily disable the firewall on both Avamar grids:
To stop the firewall service, run the following command as root:
systemctl stop avfirewall
To restart the firewall service, run the following command as root:
systemctl start avfirewall
