General OpenFlow Limitations

The following are limitations of OpenFlow support:

• OpenFlow is only supported on SSA180S and SSA150A devices with 2 GB of memory.
• Group table types “all” and “indirect” are supported; “select” and “fast-failover” are not supported.
• Only one output action is permitted per flow. For packets destined to be output to multiple ports, you must use a group table.
• An action adding an MPLS label fails if the result is a packet with more than three MPLS labels.
• This implementation of OpenFlow limits you to four controllers per switch.
• Open vSwitch provides an optional “bootstrap” mode in which a switch inherently trusts the first controller it connects to, rather than using a configured controller certificate chain to establish trust. This is not supported.
