S series switch SNMP OID


A Management Information Base (MIB) is a database that stores the variables (information that can be queried and set by the agent) on managed devices A MIB defines the attributes of managed devices, including name, status, access permission, and data type.
MIB stores information using a tree structure. The leaf nodes of the tree are managed objects (MOs). An MO is identified by the set of nodes along the path from the root to the leaf node. Such a path is called object identifier (OID). An OID consists of positive integers and zero, and it is used to uniquely identify an MO in the MIB.
For example, an SNMP object can be identified as { iso(1).org(3).dod(6).internet(1).snmpV2(6) }, which can be simplified to The identifier is called an OID.

What are the OIDs of CPU and memory usage MIBs on S series switch
On S series switches (except S1700), you can view CPU usage and memory usage through MIB OIDs: - hwEntityCpuUsage, used to query CPU usage - hwEntityCpuUsageThreshold, used to query CPU usage alarm threshold - hwEntityMemUsage, used to query memory usage - hwEntityMemUsageThreshold, used to query memory usage alarm threshold

SNMP configuration on S series switch
S series switches (except S1700 switches) support three SNMP versions: SNMPv1, SNMPv2c, and SNMPv3. SNMPv1 and SNMPv2c use community names for authentication, resulting in low security, whereas SNMPv3 uses authentication and encryption technologies to enhance security. The following uses SNMPv2c configuration as an example: [HUAWEI] snmp-agent //Enable SNMP. [HUAWEI] snmp-agent sys-info version v2c //Set the SNMP version to SNMPv2c. [HUAWEI] snmp-agent community write adminnms01 //Set the SNMP write community name. For common SNMP configuration information, see "Common SNMP Operations" in S1720&S2700&S3700&S5700&S6700&S7700&S9700 Series Switches Common Operation Guide. For typical SNMP configuration examples, see "Typical SNMP Configuration" in "Typical Network Management and Monitoring Configuration" of S1720&S2700&S3700&S5700&S6700&S7700&S9700 Typical Configuration Examples. Common configuration and typical configuration examples for S9300 and S12700 series switches are the same as those for Sx700 series switches. The Sx700 series switches are used as an example here.

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.

Whether SNMP configurations for an S series switch can be cleared
For S series switches (except S1700), the following two methods can clear SNMP configurations: 1. Run the undo command corresponding to an SNMP feature command to clear SNMP configurations. 2. Run the undo snmp-agent command to clear all SNMP configurations. The configurations will be recovered if the snmp-agent command is executed again.

Do S series switches support SNMP?
SNMP is a basic feature of S series switches (except S1700), and is supported by all device models and versions.
