3.19.1 PoE System Configuration

Use this command to configure system parameters. Interruptible power controls whether PoE power should be interrupted (shut down for 5 seconds) during the unit's software restart cycle (Enabled) or remain unchanged during the unit’s software restart cycle (Disabled). Enable/disable the PD Auto-class request (the PD communicates its effective maximum power consumption to the PSE). Specify the Legacy PD-Class mode.

Command Syntax:

poe interruptible-power poe pd-auto-class-request poe legacy-pd-class-mode { standard | poh | ignore-pd-class }

Table 3-85. Command Description
	Argument	Description
Parameter	`standard`	Extend the PD detection resistance/capacitance range beyond the IEEE® 802.3bt specification. Power Demotion, that is, when a PD is allocated power from a PSE that is lower than what the PD requested, is supported.
	`poh`	Same as Standard mode, except for PoE-AT PDs advertising class 4,4 (DSPD) or class 4 (SSPD). PoE-AT DSPD class 4,4 is offered 90W (instead of 60W). PoE-AT SSPD class 4 is offered 45W (instead of 30W). No support for Power-Demotion. Note: PoE-BT class 4,4 PD is offered 60W, and PoE-BT SSPD class 4 is offered 30W.
	`ignore-pd-class`	Port configured as Type4-90W is limited to 90W (DSPD) or 45W (SSPD) regardless of PD advertised class. No support for Power-Demotion. Port configured as Type3-60W is limited to 60W (DSPD) or 30W (SSPD) regardless of PD advertised class. No support for Power-Demotion. Port configured as Type3-30W/Type3-15W performs as if it was configured in Standard mode.
Default	N.A
Mode	Global Configuration mode
Usage	Enable PoE system parameters. To disable, use the ‘no’ version of the command.
Example	Example 1: Enable PoE interruptible power, set the PD-class mode to PoH and disable PD Auto-class. `# configure terminal (config)# poe interruptible-power (config)# poe legacy-pd-class-mode poh (config)# no poe pd-auto-class-request`
