Hi friend.
display ont port poe command is used to query the power over Ethernet(PoE) configurations and actual PoE status of an ONT eth port.
Example
To query the PoE configurations and actual PoE status of Ethernet port 1 on ONT 0 connected to port 0/3/0, do as follows:
huawei(config-if-gpon-0/3)#display ont port poe 0 0 eth 1
