Hybrid port mode OpenFlow

• A port can be enabled for hybrid port mode only if the port is untagged in the default VLAN.

• Ports in OpenFlow hybrid port mode cannot be added as untagged ports to regular VLANs or

L2VPN because this can cause a problem with topology discovery.

• As routing is enabled on a port in hybrid port mode, OpenFlow traffic or unprotected VLAN

traffic sent with destination MAC address as the port's MAC address and matching IP route

entries on the port can potentially find its VLAN and MAC address modified unless the

OpenFlow rules explicitly set the VLAN and destination MAC address in the outgoing packet.

• Inbound normal ACL configuration is not supported on the port in hybrid port mode.

• Any port with the default VLAN not equal to the system default VLAN ID cannot be enabled for

hybrid port mode.

• Policy based routing (PBR) is not supported.

• Protected VLAN traffic that does not have matching IP route entries will be dropped.

• Multiple interfaces cannot be part of a VE created on a port in hybrid port mode with a

protected VLAN.

• The following are supported on protected VLANs:

- IPv4 packets.

- BGP, OSPF and IS-IS protocols.

NOTE

Layer 2 or L2VPN, VRF are not supported.

• When protected VLANs are configured but the port is not part of the VLAN, the traffic coming

on the port with the protected VLAN will be dropped.

• Port in hybrid port mode OpenFlow doesn't support MPLS running on the same port.

These are the CLI commands for configuring different features for a hybrid port mode interface.

Enabling OpenFlow hybrid port mode

The purpose of the OpenFlow Enable command is to enable or disable hybrid port mode on the port

and the port becomes a normal port on an interface. The no version of the command disables the

hybrid port mode on the port and the port becomes a normal port.

Brocade(config-if-e10000-2/5)# openflow enable layer2 hybrid-mode

Syntax: [no] openflow enable layer2 | layer3 [hybrid-mode]

Adding or Deleting protected VLANs

The purpose of the OpenFlow protected -vlans command is to add or delete protected VLANs on a

hybrid port-mode interface. The no form of the command is used to delete the configured protected

VLANs from the hybrid port-mode port.

Brocade(config-if-e10000-2/5)# openflow protected-vlans 10

Syntax: [no] openflow protected-vlans id1 id2 …idn

VLANs can be configured individually.

NOTE

A VLAN range is not specified for this command .
