Command for displaying PoE status of S series switches:

<HUAWEI> display poe information
PSE Information of slot 0:
    User Set Max Power(mW)     : 739200     //Set the maximum output power. Use the maximum power by default.
    POE Power Supply(mW)       : 369600     //PoE power supply, which is determined by the PoE power supply configured on the device.
    Available Total Power(mW)  : 369600     //Total available power.
    Total Power Consumption(mW): 0          //Total output power.     
    Power Peak Value(mW)       : 0          //Peak output power.  
    Power-Management Mode      : auto
    Power High Inrush          : disable

Port PD class               : 2             //Classes of PDs. The system classifies PDs based on their maximum power.                                           
Port PD reference power(mW) : 7000          //Reference power of the PD.                                   
Port user set max power(mW) : 15400         //Set the maximum output power of the port.                                    
Port PD peak power(mW)      : 3816          //Peak power of the PDs connected to the port.                                          
Port PD average power(mW)   : 3487          //Average power of the PDs connected to the port.    



Does an S series switch support the detection of hardware operating status
S series switches support real-time detection of hardware operating status and generate an alarm if an exception is detected. You can use FaultID to search the product manual for the alarm explanation and solution.

Configure OSPF neighbor authentication on an S series switch
OSPF authentication of S series switches includes area authentication and interface authentication. 1. Area authentication Run the authentication-mode command in an OSPF area view to set the authentication mode and password for the OSPF area. For example: [HUAWEI] ospf 100 [HUAWEI-ospf-100] area 0 [HUAWEI-ospf-100-area-0.0.0.0] authentication-mode simple cipher huawei To configure MD5 authentication, run the following command: [HUAWEI-ospf-100-area-0.0.0.0] authentication-mode md5 1 cipher huawei 2. Interface authentication The interface authentication mode is used among neighbor switches to set the authentication mode and password. Its priority is higher than that of the area authentication mode. Run the ospf authentication-mode command in the interface view to set the authentication mode and password for adjacent switches. For example: [HUAWEI] interface vlanif 100 [HUAWEI-Vlanif100] ospf authentication-mode simple cipher huawei To configure MD5 authentication, run the following command: [HUAWEI-Vlanif100]ospf authentication-mode md5 1 cipher huawei Note: When configuring area authentication or interface authentication, all switches involved must have the same authentication mode and password. If not, the switches may fail to set up an OSPF neighbor relationship.
