Step Command Remarks
3. Set the connection mode for the
OpenFlow instance to establish
connections to controllers.
controller mode { multiple |
single } By default, the connection mode
is multiple.
Configuring the maximum number of flow entries
To improve OpenFlow availability, extensibility flow table can have a maximum number of flow entries.
When entries in a table reaches the maximum number, the OpenFlow instance does not accept new flow
entries for that table and sends a deployment failure notification to the controller.
To configure the maximum number of flow entries that each extensibility flow table supports:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter OpenFlow instance
view.
openflow instance instance-id N/A
3. Configure the maximum
number of extensibility flow
entries.
flow-entry max-limit limit-value
By default, an OpenFlow
extensibility flow table supports at
most 1024 flow entries.
Configuring in-band management VLANs
In-band management VLANs of an OpenFlow instance are part of the VLANs associated with the
OpenFlow instance. In-band management VLANs are used to establish connections between the
OpenFlow instance and controllers in an OpenFlow instance.
When the in-band management VLANs are configured, the data packets within the in-band
management VLANs are not forwarded through OpenFlow, and the ports that are assigned to only
in-band management VLANs are not OpenFlow ports. Before configuring in-band management VLANs,
you must plan the network.
To configure in-band management VLANs:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter OpenFlow
instance view.
openflow instance instance-id N/A
3. Configure in-band
management VLANs. in-band management vlan vlan-list
By default, no in-band management
VLAN is configured.
The in-band management VLANs of an
OpenFlow instance must be within the list
of the VLANs that are associated with the
OpenFlow instance.
