  • High: indicates the second highest priority.
  • Low: indicates the lowest priority.

To set the priority, run the poe priority command.

Max power(mW)

Maximum output power of an interface. A maximum output power of 15400 mW indicates that the device complies with IEEE 802.3af. A maximum output power of 30000 mW indicates that the device complies with IEEE 802.3at.

To set the value, run the poe power command.

Current power(mW)

Current output power of an interface.

Peak power(mW)

Peak output power of an interface.

Average power(mW)

Average output power of an interface.

Current(mA)

Output current of an interface.
