Hybrid switch and OpenFlow hybrid port mode
1
• Packets tagged with a protected VLAN id will be forwarded by IPv4 and IPv6 unicast
routing, if IPv4 or IPv6 routing is configured on that VLAN. If IPv4 or IPv6 routing is not
configured on that VLAN, such packets will be dropped.
• Packets tagged with an unprotected VLAN id:
• Packets tagged with an unprotected VLAN id will be subject first to OpenFlow flows. If there
is a match on an OpenFlow flow, the packet will be forwarded according to the flow actions.
No further IPv4 or IPv6 routing is supported for packets that are forwarded by OpenFlow
flows. If there is no match on any OpenFlow flow, the packet will be forwarded by IPv4 or
IPv6 unicast routing, if IPv4 or IPv6 routing is configured on the VLAN. If IPv4 or IPv6
routing is not configured on the VLAN, those packets are either dropped or sent to the
controller, per OpenFlow configuration..
• Layer 2 or L2VPN forwarding is not supported on ports in hybrid-enabled ports because MAC
learning is disabled on these ports.
• 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.
• BGP, OSPF and IS-IS protocols are supported on protected VLANs:
NOTE
Layer2 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-enabled OpenFlow doesn't support MPLS running on the same port.
• Link aggregation is not supported.
Enabling OpenFlow hybrid port mode
Use openflow enable command 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.
