Component Behavior
DAI If DAI is configured along with a MAC-address modification
flow, DAI operates on the modified MAC address instead of
original MAC address.
Static MAC filter OpenFlow flow forwarding takes precedence over static MAC
filtering. Traffic is forwarded according to flow rule.
IPv6 Destination
Address Match
This is not supported on the N4000 due to hardware
limitations.
Disable iSCSI to install flows matching the IPv6 destination
address.
