Since LACP is run on the NI it is important to verify the NI has the proper information. Many of the same
commands run above are available in the NI debugger. (See the table below.) The syntax and output are
the same.
la_ni_agg_prt
la_ni_port_prt
la_ni_port_up_prt
la_ni_lacp_port_stats_prt
la_ni_trace_prt
lagg_Sock_ni_traceprint
lagg_Sock_ni_boardupprint
To look at LACP statistics use the la_ni_lacp_port_stats_prt command. It monitors real time LACP-
DUs. It is important to verify that receive and transmit are incrementing on all active ports in a LACP
aggregate.

Note. LACPDUs are processed on the CMM.
If writing a PR for link aggregation it can be useful to attach the output of the Dshell command
la_cmm_trace_prt, which displays the actions/events the CMM handled.
