1532 Power Over Ethernet Commands
The default guard band is 90% of maximum power supplied to the system.
Assuming a maximum current draw of 31.2W per device and the default
settings for PoE, the N2024P can power 32 devices using a single power
supply and the N2048P can power 31 devices with a single power supply and
48 devices when using two power supplies. If a PD is detected that is
requesting class-based power allocation via LLDP and either static or
dynamic power allocation is configured, a log message is issued indicating
that a class based PD is requesting power. The device will not be powered
until class based power management is configured.
Example
In the following example, no port is specified so the command displays global
configuration and status of all the ports. Configure the global power
management scheme as dynamic with dot3af+legacy detection and enable
PoE capability on ports gi1/0/1-10.
console(config)#power inline management dynamic
console(config)#power inline detection dot3af+legacy
console(config)#interface range gi1/0/1-10
console(config-if)#power inline auto
console(config-if)#exit
console#show power inline
