Configuring OpenFlow Instances with Multiple VLANs
Hewlett Packard Enterprise recommends that the OpenFlow instance VLAN membership be
identical throughout the controlled network topology. If an OpenFlow instance contains a set of
VLANs on one switch, then neighboring switches should also have an OpenFlow instance with
the same set of VLANs. For network topologies that contain both ProVision and Comware
OpenFlow instances, configure the ProVision aggregate mode and Comware Openflow instances
to contain all VLANs.
You should untag inter-switch links in the OpenFlow instance VLANs. Alternatively, you can tag
these links in the OpenFlow instance VLANs. Default the untagged traffic to one of the OpenFlow
instance VLANs.
Hewlett Packard Enterprise recommends the following mixed ProVision/Comware topology switch
configuration:
•
ProVision – ProVision
Instance: Aggregate OpenFlow instance on all switches or virtualized only instances on all
switches
Interface: Any valid configuration
•
ProVision – Comware
Instance: ProVision Aggregate, Comware group = all
Interface: Comware interswitch link port PVID in OpenFlow instance
•
Comware – Comware
Instance: Consistent OpenFlow instance VLAN configuration throughout topology
Interface: Interswitch link port PVID in OpenFlow VLAN
Configuring OpenFlow Instances with Single VLAN Identifier
In a topology that contains both Comware and ProVision switches, if the ProVision switch
OpenFlow instance is configured for a single VLAN, configure the Comware OpenFlow instance
to a single VLAN as well.
In some cases, when the ports of the inter-switch link between the ProVision and Comware
devices are configured as tagged-only, the link from the Comware device to the ProVision device
may not be discovered. In order for links to be correctly discovered in these configurations,
configure the controller to insert a VLAN tag when injecting link discovery packets on the Comware
device. Use the device REST API to configure the appropriate
linkDiscoveryVlan
that
matches the VLAN identifier configured in the Comware device OpenFlow instance.
