Troubleshooting PoE
Failure to set the priority of a PoE interface to critical
Analysis
• The guaranteed remaining power of the PSE is lower than the maximum power of the PoE interface.
• The priority of the PoE interface is already set.
Solution
• In the first case, either increase the maximum PSE power or reduce the maximum power of the PoE
interface if the guaranteed remaining power of the PSE cannot be modified.
• In the second case, remove the priority that is already configured.
Failure to apply a PoE profile to a PoE interface
Analysis
• Some configurations in the PoE profile are already configured.
• Some configurations in the PoE profile do not meet the configuration requirements of the PoE
interface.
• Another PoE profile is already applied to the PoE interface.
Solution
• In the first case, remove the original configurations.
• In the second case, modify the configurations in the PoE profile.
• In the third case, remove the application of the undesired PoE profile from the PoE interface.
