poe group management enable
Function
The poe group management enable command enables a PoE device's group management of PDs.
The undo poe group management enable command disables a PoE device's group management of PDs.
By default, a PoE device's group management of PDs is disabled.
Among PoE models, theS5720-14X-PWH-SI-AC, S5735-L, S5735S-L, S5735S-L-M, S5735-S, S5735-S-I, S5731-H, S5731-S, and S5731S-S do not support this command.
Usage Guidelines
Usage Scenario
Powering on some PDs may affect other PDs, causing other PDs unable to be detected by a PoE device. After group management of PDs is enabled, a PoE device can detect PDs on a per-group basis and power on these PDs in a batch.
Precautions
To support a PoE device's group management of PDs, every four interfaces on the left are added to one group. For example, interfaces numbered 1 to 4 or numbered 5 to 8 can be added to one group, but interfaces numbered 2 to 5 cannot. That is, the number of the last interface in each group must be the multiple of 4. If the poe group management enable command is configured on any interface in a group, this command is also delivered to the other three interfaces in the same group.
After group management of PDs is configured on an interface, the other interfaces in the same group use the same power supply priority as this interface and this priority is lower than that of other interfaces that are not added to any group. If some interfaces have this group management function configured, the PoE interface power supply priority configured using the poe priority command does not take effect on these interfaces.
