Real-time accounting cannot be disabled on an S series switch after the undo accounting realtime command is configured

2

You can run the undo accounting realtime command on an S series switch to disable the real-time accounting function. However, if the RADIUS server delivers an Acct-Interim-Interval message to the switch to require the switch to start accounting in real time, the configuration delivered by the RADIUS server takes effect.
In this case, you can only to disable RADIUS attributes on the switch to disable real-time accounting. Configure the radius-attribute disable command in the RADIUS server template to disable the Acct_Interim_Interval attribute. The configuration is as follows:
[HUAWEI] radius-server template rt1
[HUAWEI-radius-rt1] radius-attribute disable Acct-Interim-Interval receive send

Enable and disable PoE on an S series switch
Enable or disable the PoE function on S series switches:

1. By default, the PoE function is enabled on an interface
2. Enable or disable PoE power supply.
<HUAWEI>system-view
[HUAWEI]interface gigabitethernet 1/0/0
[HUAWEI-GigabitEthernet1/0/0]undo poe enable  //Disable PoE power supply.
[HUAWEI-GigabitEthernet1/0/0]poe enable       //Enable PoE power supply.

The downlink electrical interfaces of PoE switches support PoE power supply, with up to 30 W power on each interface. The maximum power supply distance is 100 m.
Only ES0D0G48VA00 (S7700)/LE0DG48VEA00 (S9300) cards of modular switches (S7700/S9700/S9300/S12700) support PoE power supply.

If the switch connects to 48 V standard PoE powered devices but cannot negotiate power supply capabilities with the devices, you can run poe force-power on the interfaces to forcibly power on the devices.


Function of the bpdu enable command on S series switch
On an S series switch, except S1700, the bpdu enable command sends BPDUs to the CPU for processing. S series switches: In the versions earlier than V100R006, BPDUs are discarded by default. In V100R006 and later versions, BPDUs are sent to the CPU by default. E series switches: BPDUs are sent to the CPU by default. Run the display bpdu mac-address command to check which packets are determined as BPDUs. The bpdu mac-address command configures packets as BPDUs.

How to enable log display on the terminal or console for S series switches
For S series switches (except the S1700), you can use the following commands to enable log display on the terminal or console: - terminal debugging: enables the debug message display function on the terminal or console. - terminal logging: enables the log display function on the terminal or console. - terminal trapping: enables the trap display function on the terminal or console. - terminal monitor: enables the terminal or console to display messages sent from the information center. The terminal or console displays messages only after the terminal monitor command and any of the other three commands are configured. This function is enabled by default if you log in to the console through the console port. This function is disabled by default if you log in to the terminal using Telnet, and must be enabled using the terminal monitor command.
