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 the:
- Number of PoE Ports on the Switch
- PoE Controller Configuration and Status
- PoE Interface Configuration and Status
- PoE SNMP Trap Generation Status
Number of PoE Ports on the Switch
Purpose
Verify the number of PoE ports on a switch. The number of PoE ports on a switch varies according to switch model.
Action
Enter the following command:
user@switch> show chassis hardware Hardware inventory: Item Version Part number Serial number Description Chassis BH0208375304 EX3200-24T Routing Engine 0 REV 11 750-021261 BH0208375304 EX3200-24T, 8 POE FPC 0 REV 11 750-021261 BH0208375304 EX3200-24T, 8 POE CPU BUILTIN BUILTIN FPC CPU PIC 0 BUILTIN BUILTIN 24x 10/100/1000 Base-T Power Supply 0 REV 03 740-020957 AT0508285661 PS 320W AC Fan Tray Fan Tray
Meaning
The switch is an EX3200-24T model with eight PoE ports.
PoE Controller Configuration and Status
Purpose
Verify the PoE controller configuration and status, such as the PoE power budget, total PoE power consumption, and power management mode.
Action
Enter the following command:
user@switch> show poe controller Controller Maximum Power Guard band Management index power consumption 0 130 W 43W 15W Class
Meaning
The switch has an overall PoE power budget of 130 W, of which 43 W were being used by the PoE ports 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 power management mode is class.
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 interface Interface Admin status Oper status Max power Priority Power consumption Class ge-0/0/0 Enabled ON 15.4W Low 7.9W 3 ge-0/0/1 Enabled ON 15.4W High 4.8W 0 ge-0/0/2 Enabled ON 15.4W High 4.8W 0 ge-0/0/3 Enabled ON 15.4W High 3.3W 2 ge-0/0/4 Disabled Disabled 0.0W Low 0.0W 0 ge-0/0/5 Enabled ON 15.4W Low 3.2W 2 ge-0/0/6 Enabled ON 15.4W Low 3.3W 2 ge-0/0/7 Enabled OFF 15.4W Low 0.0W 0
To view configuration and status for a single PoE interface, enter:
user@switch> show poe interface ge-0/0/3 PoE interface status: PoE interface : ge-0/0/3 Administrative status : Enabled Operational status : ON Power limit on the interface : 15.4W Priority : High Power consumed : 3.3W Class of power device : 2
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 the interface can deliver is 15.4 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.
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-control
FPC slot Notification-control-status
0 OFFMeaning
PoE SNMP traps are not enabled.
