Verifying PoE Configuration and Status (CLI Procedure)

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:

Example output for an EX2200 switch:

Example output for an EX8200 switch:

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.

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:

To view the configuration and status for the PoE interfaces on an EX6200 or EX8200 line card:

To view configuration and status for a single PoE interface, enter:

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.

Purpose

Verify the status of the notification-control option, which determines whether or not PoE SNMP traps are enabled.

Action

Enter the following command:

Meaning

PoE SNMP traps are not enabled.

Purpose

Verify the PoE configuration and status for line cards on an EX6200 or EX8200 switch, such as the PoE power allocation and priority for each line card.

Action

Enter the following command:

Example output for an EX6200 switch:

Example output for an EX8200 switch:

Meaning

• For the EX6200 switch—The total of the PoE power budgets allocated to the line cards in the switch is 5920 W. This figure includes the 37 W of PoE power always included in the base allocation for each line card that supports PoE. For line cards with PoE ports, the PoE power field shows the PoE power budget allocated to each line card, along with the line card priority.

• For the EX8200 switch—The total of the PoE power budgets allocated to the line cards in the switch is 1707 W. This figure includes the 37 W of PoE power always included in the base allocation for each line card that supports PoE. For line cards with PoE ports, the PoE power field shows the PoE power budget allocated to each line card, along with the line card priority.
