Hybrid port mode operation
Consider Device-1 in
Figure 3
. Ingress traffic on VLAN 10 on hybrid port 1/1 will be processed for
IPv4 and IPv6 unicast routing. Traffic on other VLANs will be processed against OpenFlow flows on
port 1/1 and switched accordingly. A preconfigured number of protected VLANs can be supported
for normal routing. The Spanning tree protocols (STP) state of these routing VLANs will be set to
forwarding, as the Layer 2 protocol is not supported.
Configuring OpenFlow hybrid port mode
1. Enable OpenFlow at the global configuration level.
2. Configure OpenFlow controller configurations.
3. Configure the system maximum configuration for the maximum OpenFlow entries. (The default
is 0.)
4. Configure the maximum OpenFlow flow-protected VLAN entries. (The default is 0.)
NOTE
System reload is required once you change the system maximum values.
5. Configure the maximum OpenFlow unprotected VLAN entries. (The default is 0.)
6. Configure protected VLANs on the port. A maximum of 40 protected VLANs can be configured
on an OpenFlow port.
7. Enable OpenFlow hybrid port mode on the desired interfaces.
8. Configure a VE for the interface by specifying the protected VLAN and add routing entries.
Feature information
•
Switchover and HLOS are not supported. When the active management processor (MP) goes
down, communication with the controller is brought down and the flow tables on the MP and all
line processors (LP) are cleared. The connection with the controller is re-established after
switchover.
•
When LP is reset, the flow table on the LP is restored once the LP comes up and flows specific
to that LP are maintained in the MP.
•
When an OpenFlow-enabled port goes up or down, no rules are removed. The addition or
deletion of rules depends solely on the controller.
•
4K OpenFlow entries are supported.
•
Up to 2K protected VLANs per system are supported.
