DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide Interface Configuration Mode. Command Default Level Level: 12. Usage Guideline Use this command to enable the support of legacy PDs connected to the port. If legacy support is disabled, the system will not provide power to the legacy PDs. Example This example shows how to enable legacy support for PDs connected to interface eth3/0/1. Switch# configure terminal Switch(config)# interface eth3/0/1 Switch(config-if)# poe pd legacy-support Switch(config-if)# 51-3 poe pd priority This command is used to configure the priority for provisioning power to the port. Use the no command to return the priority to the default setting. poe pd priority {critical | high | low} no poe pd priority Parameters critical high low Specifies the PD connected to the port gains the highest priority. Specifies the PD connected to the port gains the second high priority. Specifies the PD connected to the port gains the lowest priority. Default By default, this option is set as low. Command Mode Interface Configuration Mode. Command Default Level Level: 12. Usage Guideline Since the power budget is limited, as more PDs are added to the system, the power source may not be sufficient to supply the power. The PoE system enters the power critical section when the remaining power source is not enough to serve the new added PD. Whether power is supplied to the new added PD will depend on the policy configured by poe policy preempt command. If the policy preempt setting is disabled, then the policy is first in first serviced. Thus the new PD will not be serviced if the power source is running out. If the policy preempt setting is enabled, then the power provisioned to PD with lower priority can be preempted in order to release power to the new connected PD with higher priority. Example This example shows how to configure the priority of eth 3/0/1 to the first priority. 451
