Configuring flow table IDs
You can configure one MAC-IP flow table and one extensibility flow table for an OpenFlow instance. For
an OpenFlow instance, the MAC-IP flow table ID must be smaller than the extensibility flow table ID.
To configure flow table IDs for an OpenFlow instance:
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 flow table ID.
flow-table { extensibility table-id |
mac-ip table-id }*
By default, OpenFlow supports
only one flow table with an ID of 0,
which is the extensibility type.
An OpenFlow instance supports
only one MAC-IP flow table and
one extensibility flow table. If you
execute the command multiple
times, the most recent
configuration takes effect.
Setting the connection mode for an OpenFlow instance to
establish connections to controllers
The following connection modes are available for an OpenFlow instance to establish connections to
controllers:
•
Single—The OpenFlow instance connects to only one controller at a time. When communication
with the current controller fails, the OpenFlow instance uses another controller. In this mode, an
OpenFlow instance attempts to connect to a controller one by one according to the controller ID in
ascending order until it successfully connects to a controller. If multiple controllers that are
configured for the OpenFlow instance are unreachable, the OpenFlow instance might take a long
time to connect to a reachable controller.
•
Multiple—The OpenFlow instance can simultaneously connect to multiple controllers. When
communication with a controller fails, the OpenFlow instance attempts to reconnect to the controller
after a reconnection interval.
To set the connection mode for an OpenFlow instance to establish connections to controllers:
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 mode for the
OpenFlow instance to establish
connections to controllers.
controller mode { multiple |
single }
By default, the connection mode
is multiple.
