L3 Unicast Group entry. Selection of an action bucket for forwarding a
particular packet is hardware specific.
• Action Buckets
The action buckets contain the single value listed in Table 46-19.
• Counters
The L3 ECMP group entry counters are as shown in Table 46-20.

Port Configuration, Status and Statistics
The Dell EMC Networking OpenFlow Hybrid switch does not support any
port configuration commands. The OFPT_PORT_MOD messages from the
OpenFlow controller do not modify the port configuration.
The Dell EMC Networking OpenFlow Hybrid switch reports port creation,
removal, and status changes to the controller using the
OFPT_PORT_STATUS message. The message is sent for physical ports and
LAGs. All three reason codes, OFPPR_ADD, OFPPR_DELETE, and
OFPPR_MODIFY, are supported for all port types.
The only trigger for the OFPPR_MODIFY reason code is a link status change
for the port.
