Question :

How do I check which IEEE standard the PoE port operates under using the CLI?

Answer :

The user can use the CLI "show state poe port port-number" to check the current POE IEEE standard. For instance, the user checks that the mode is AT for Port 3 of the USG Flex 500H, as shown below:

usgflex500h> show state poe port p3
port p3
pd-enable PORT_ENABLE
state R_GOOD
mode AT
class 4
power "5.601 W"
current "101.750 mA"
temperature 35.62
..
