What are SNMP commands and what are their functions for S series switches

15

S series switches (except S1700) use different commands to implement different SNMP functions. For example:
snmp-agent //Enable SNMP.
snmp-agent sys-info version //Configure the SNMP version.
snmp-agent community //Configure an SNMP read-write community name.
snmp-agent target-host trap //Configure the destination address to receive traps.
snmp-agent community complexity-check disable //Disable community name complexity check.
For details on SNMP commands, click S2750&S5700&S6700 V200R003(C00&C02&C10) Command Reference and choose Network Management and Monitoring Commands > SNMP Configuration Commands.
Choose corresponding materials based on the device model and version. S series fixed switches are used here as an example.

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.

What is SNMP for S series switches
The Simple Network Management Protocol (SNMP) is a standard network management protocol widely used on TCP/IP networks. Devices function as agents and can be managed and monitored by the manager (NMS). A network administrator can query information, modify data, and locate faults on devices through SNMP, greatly improving work efficiency.

What is the function of the default-ip-address command for BFD on S series switches
For S series switches (except S1700): When using BFD to detect the physical status of a link, you may not specify the peer IP address (In some situations, the peer such as an Eth-Trunk member interface is not assigned an IP address). In this case, you need to bind a BFD session to a multicast IP address so that BFD control packets can be sent to the peer device. In either of the following situations, change the default multicast IP address: - On the live network, other protocols except BFD use the multicast IP address. - Multiple BFD sessions exist on a path. For example, because Layer 3 interfaces are connected through Layer 2 switching devices that support BFD, configure different default multicast IP addresses for the devices where different BFD sessions are established. You can run the default-ip-address ip-address command to configure the default multicast IP address for BFD. [HUAWEI] bfd [HUAWEI-bfd] default-ip-address 224.0.0.150
