Verifying PoE Configuration and Status (CLI Procedure)
You can verify the Power over Ethernet (PoE) configuration and status on an EX Series switch.
This topic describes how to verify:
- PoE Controller Configuration and Status
- PoE Interface Configuration and Status
- PoE SNMP Trap Generation Status
PoE Controller Configuration and Status
Purpose
Verify the PoE controller configuration and status, such as the PoE power budget, total PoE power consumption, power management mode, and the supported PoE standard.
Action
Enter the following command:
user@switch> show poe controllerExample output for an EX2200 switch:
Controller Maximum Power Guard Management Status Lldp index power consumption band Priority 0 405.00W 130.00W 19W Class AT_MODE Disabled
Example output for an EX8200 switch:
Controller Maximum Power Guard Management Status Lldp index power consumption band Priority 3 540.00W 435.25W 0W Static AT/AF COMBO Disabled 4 915.00W 627.01W 15W Class AT/AF COMBO Disabled
Meaning
- For the EX2200 switch—The switch has a PoE power budget of 405 W, of which 130 W were being used by the PoE ports at the time the command was executed. The Guard band field shows that 19 W is reserved out of the PoE power budget to protect against spikes in power demand. The power management mode is class. The PoE ports on the switch support PoE+ (IEEE 802.3at).
- For the EX8200 switch—Line card 3 has a PoE power
budget of 540 W, of which 435.25 W were being used by the PoE ports
on the line card at the time the command was executed. The management
mode for line card 3 is static and the line card has a mix of PoE
(IEEE 802.3af) and PoE+ (IEEE 802.3at) ports.
Line card 4 has a PoE power budget of 915 W, of which 627.01 W were being used by the PoE ports on the line card at the time the command was executed. The Guard band field shows that 15 W is reserved out of the PoE power budget to protect against spikes in power demand. The management mode for line card 4 is class and the line card has a mix of PoE (IEEE 802.3af) and PoE+ (IEEE 802.3at) ports.
PoE Interface Configuration and Status
Purpose
Verify that PoE interfaces are enabled and set to the correct maximum power and priority settings. Also verify current operational status and power consumption.
Action
To view configuration and status for all PoE interfaces, enter:
user@switch> show poe interfaceInterface Admin Oper Max Priority Power Class

ge-3/0/39 Enabled ON 15.4W Low 2.2W 1To view configuration and status for a single PoE interface, enter:
user@switch> show poe interface ge-0/0/3PoE interface status: PoE interface : ge-0/0/3 Administrative status : Enabled Operational status : ON Power limit on the interface : 7.0W Priority : High Power consumed : 3.3W Class of power device : 2 PoE Mode : 802.3at
Meaning
The command output shows the status and configuration of interfaces. For example, the interface ge-0/0/3 is administratively enabled. Its operational status is ON; that is, the interface is currently delivering power to a connected powered device. The maximum power allocated to the interface is 7.0 W. The interface has a high power priority. At the time the command was executed, the powered device was consuming 3.3 W. The IEEE 802.3af class of the powered device is class 2. If the PoE power management mode is class, the class of the powered device determines the maximum power allocated to the interface, which is 7 W in the case of class 2 devices.
The PoE Mode field indicates that the interface supports IEEE 802.3at.
PoE SNMP Trap Generation Status
Purpose
Verify the status of the notification-control option, which determines whether or not PoE SNMP traps are enabled.
Action
Enter the following command:
user@switch> show poe notification-controlFPC slot Notification-control-status
0 OFFMeaning
PoE SNMP traps are not enabled.
