Preparing for configuration

Plan your network including production and OpenFlow VLANs, OpenFlow instances, OpenFlow controller ports, listening ports, naming and numbering strategy.

Plan the number of VLANs configured for OpenFlow versus non-OpenFlow.

OpenFlow works on an instance only when OpenFlow is enabled on the instance as well as globally on the switch.

NOTE:
  • A maximum of 128 OpenFlow instances can be configured (16 on 2920 and 2930F switches).
  • By default, a maximum of 2048 VLANs are supported, but if you change the MAX VLANs to 4096, OpenFlow supports all 4096 VLANs.
  • A maximum of 64000 OpenFlow rules can be added for 5400R/3810 (16000 for 2920 and 2930F).
  • A maximum of 128 controllers can be configured (16 for 2920 and 2930F).
  • A maximum software rate limit of 10000 pps can be configured (2000 for 2920 and 2930F).
