Setting OpenFlow timers
An OpenFlow switch supports the following timers:
• Connection detection interval—Interval at which the OpenFlow switch sends two consecutive Echo
Request messages to a controller. The OpenFlow switch can send up to three Echo Request
messages. If none of the requests receives a reply, the OpenFlow switch is disconnected from the
controller.
• Reconnection interval—Interval for the OpenFlow switch to wait before it attempts to reconnect to a
controller.
To set OpenFlow timers for an OpenFlow switch:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter OpenFlow instance
view.
openflow instance instance-id N/A
3. Set the connection detection
interval. controller echo-request interval
interval-value
The default setting is 5 seconds.
To reduce the CPU load, H3C
recommends that you set the
connection detection interval to a
large value.
4. Set the reconnection interval. controller connect interval
interval-value
The default setting is 60 seconds.
Configuring OpenFlow to support dynamic MAC
addresses
On an OpenFlow switch that supports MAC-IP flow tables, you can configure OpenFlow to support
querying and deleting dynamic MAC addresses in the flow tables.
To configure OpenFlow to support dynamic MAC addresses:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter OpenFlow instance
view.
openflow instance instance-id N/A
3. Configure OpenFlow to
support dynamic MAC
addresses. mac-ip dynamic-mac aware
By default, OpenFlow prohibits
controllers from querying and
deleting dynamic MAC addresses.
This feature is applicable only to
OpenFlow instances in VLAN
mode.
