Description
The port number.
Indicates whether PoE is administratively enabled or disabled on the port. This feature is
enabled by default on ports that support PoE.
The priority of the port when allocating available power. Power is delivered to the higher-
priority ports when needed before providing it to the lower priority ports. Possible values
are High, Low, and None. None is the lowest priority and the default for all ports.
The scheduled time, if any, when source power is available on this port. Options are:
• None—Source power is available at all times (subject to the port priority). This is the
default selection.
• Schedule 1—Source power is available during the configured first schedule.
• Schedule 2—Source power is available during the configured second schedule.
You can configure schedules on the PoE Port Schedule page.
When enabled, the port supports the original PoE standard and the PoE+ standard, which
allows for providing up to 30W of power. When disabled, the port supports the original PoE
standard only, which allows for providing up to 15.4W of power. This setting is disabled by
default.
If PoE+ functionality is required, this setting must be enabled on the port, even when the
switch is configured to operate in Dynamic Power Management mode (see
Configuration" on page
8-2).
The PD detection mechanism performed by the PSE port. Possible value are:
• Dot3af/at—The 4-point detection scheme defined in IEEE 802.3af is used. This is the
default option.
• Dot3af/at + Pre-Standard—The 4-point detection scheme defined in IEEE 802.3af is
used. If this mechanism fails to detect a connected PD, Dot3af/at detection is used.
