MY-SWITCH# show platform fwm info pif ethernet 2/2 | inc slot_asic
Eth2/2 pd: slot 1  logical port num 1  slot_asic_num 0  global_asic_num 5 fw_inst 4  phy_fw_inst 1 fc 0

Note: The slot numbers are 0-based, whereas the bigsur instances are 1-based. Therefore, in this example slot 1 corresponds to bigsur instance 2.

=> slot 1 become 2 in the elam command, the instance stay the same as the slot_asic_num => ingress for the traffic ingressing the interface, egress for the egressing traffic.
