Enabling packet loss prevention for OpenFlow
forwarding
In networks that require high OpenFlow forwarding performance, packet loss might occur on the switch
during the flow entry deployment process. The packet loss then causes OpenFlow forwarding to fail. You
can enable packet loss prevention to ensure successful OpenFlow forwarding without packet loss.
When this feature is configured, ACLs cannot match packets by IPv6 address.
After you enable or disable packet loss prevention, save the configuration and restart the switch to make
the configuration take effect.
To enable packet loss prevention for OpenFlow forwarding:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enable packet loss prevention
for OpenFlow forwarding.
openflow lossless enable
By default, the packet loss
prevention feature for OpenFlow
forwarding is disabled.
