swPoESystemManagementMode

Module: PoE-MIB

OID (symbolic): PoE-MIB::swPoESystemManagementMode

OID (numeric): 1.3.6.1.4.1.171.12.24.1.3

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This mode can be either power_limit mode or auto mode. power_limit: If power supplied to the port exceeds the power limit specified for it, this port will be shut down. auto: The system will automatically determine the PD class of the device connected to the port in the first stage. Normally, the PD can be classified as class 1, 2, or 3. If the PD cannot be classified, it will be classified as class 0. For class 0, it will assume that the PD may consume the max power allowed. During the power feeding stage, if the power supplied to the port exceeds the upper limit of the detected PD class, this port will be shut down. For the upper limit for each class, it is 4W for class 1 PD class, 7W for class 2, and 15.4W for class 3 PD and class 0 PD.

What is swPoESystemManagementMode?

Selects how per-port power limits are enforced: power-limit(1) shuts a port down if it exceeds its configured limit, while auto(2) auto-detects the connected device's 802.3af PD class (0-3) and shuts the port down if it exceeds that class's power ceiling (4W for class 1, 7W for class 2, 15.4W for class 3/0).
