Power over ethernet (PoE)

Power over ethernet (PoE) allows a single cable to provide both a data and power connection to devices such as wireless access points, IP cameras and VoIP phones.

set poe global power threshold

Change the global power budget of the POE module.

Syntax: set poe global power threshold <value>

Mode: Global Configuration Mode.

power inline

Turn on or turn off POE on the specified port.

Syntax: power inline { enable | disable }

Mode: Interface Configuration Mode

power legacy mode

Turn on or turn off legacy PoE mode.

Legacy PoE is only required when you have PoE-capable devices that aren't 802.3af or 802.3at compliant and require non-standard PoE connected to Sophos Switch. For example, legacy IP phones.

This command is only available on the following Sophos Switch models:

  • CS110-24FP
  • CS110-48P
  • CS110-48FP
  • CS210-8FP
  • CS210-24FP
  • CS210-48FP
  • CS1010-8FP

Syntax: power legacy mode {enable | disable}

Mode: Interface Configuration Mode.

power inline limit

Limit POE on the specified port.

Syntax: power inline limit { auto | <value> }

Parameter Description:

  • auto: Automatically allocates power to the PoE port after device detection if enough power is available.
  • <value>: The maximum wattage feature limits the power allocated to the port.

Mode: Interface Configuration Mode.

power inline priority

Set the priority of POE on the specified port.

Syntax: power inline priority { critical | high | medium | low }

Parameter Description:

  • critical: Sets the Power Over Ethernet port priority to critical.
  • high: Sets the Power Over Ethernet port priority to high.
  • medium: Sets the Power Over Ethernet port priority to medium.
  • low: Sets the Power Over Ethernet port priority to low

Mode: Interface Configuration Mode.

power reset interval

Set the time in seconds a PoE port will shut down when running the power reset command.

Syntax: power reset interval <1-300>

Mode: Interface Configuration Mode.

power reset

Reset the power on the PoE ports. The ports will shut down for the time specified using the power reset interval command before powering back on.

Syntax: power reset

Mode: Interface Configuration Mode.

show power detail

Show the POE power supply status information, such as PoE global admin status, PSE operational status, and maximum power supply.

Syntax: show power detail

Mode: Privileged EXEC Mode

show power inline

Show the POE power supply status information of each pse.

Syntax: show power inline [{<interface-type> <interface-id>}]

Parameter Description:

  • <interface-type>: Displays the information about the specified type of interface. Choose from the following options:

    • gigabitethernet
    • port-channel

  • <interface-id>: Shows the information about the specified interface identifier. This is a unique value that represents the specific interface. This value is a combination of slot number and port number separated by a slash. For example, 0/1 represents that the slot number is 0 and the port number is 1.

Mode: Privileged EXEC Mode.
