The following information describes OF implementation restrictions:
SR OS Hybrid OpenFlow Switch requires a software upgrade only and can be enabled on any switch. For full functionality, performance, and future scale, IOM3-XP or newer line cards and CPM4 or newer control cards are recommended.
Some platforms may not support all OF functionality based on the underlying hardware. For example, if the underlying hardware does not support IPv6, OF IPv6 functionality is not supported. If the underlying hardware does not support redirect to LSP, redirect action is ignored.
Each flow in an OF flow table must have unique priority. Overlap is not supported.
Timed expiry of the flow entries is not supported.
The implementation is compliant by design with OpenFlow specification as applicable to supported router functionality only.
