monitoring by acquiring the value of the MIB object, or by modifying the value of the special variable to enable the agent to perform an action or modify the configuration of the resource. Many management station application process has the graphical user interface, provides the data analysis, the fault discovery function, the network manager can conveniently check the network condition and takes the action when needs.

In project implementation and network device debugging, we often need to find the subnet mask and default gateway of the device so as to correctly configure devices such as routers, switches, and firewalls.

Based on the above considerations, I decided to use the IP Network Browser tool for the range of 210. 224. *. 1 ~~~ 210. 224. *. 254 IP segment scan to check whether a network device of a Cisco router or vswitch is used. It must be noted that IP Network Browser is a tool in the SolarWinds Network management software set. It can be used to scan Network devices in an IP segm

the SN MP Standard introduces a set of ASN.1 language elements called SMI (Structure of Managementinformation). The interrelated managed objects (Managed Objects) described by SMI comprise the MIB (managementinformation Base) module. The frequently used managedobjects in the core MIB becomes part of the SNMP standard. The rest of the MIB is typically created by d
Using the firewall and the memory pool MIB (using the Firewall and Memory pool MIBs)
The Cisco firewall and memory Pool MIB allow you to poll for failover and system state. This section includes the following:
o ipaddrtable notes (ipaddrtable notes)
o Browse for failover status (viewing Failover status)
o Verify memory usage (verifying Memory Usage)
o Browse Connection number (viewing the Connection count)

The predecessor of the Simple Network Management Protocol (SNMP) is the simple gateway monitoring protocol (sgmp), which is used to manage communication lines. Subsequently, sgmp was greatly modified, especially when SMI and MIB compliant with Internet definitions were added: the improved protocol was the famous SNMP. The goal of SNMP is to manage software and hardware platforms produced by many manufacturers on the Internet. Therefore, SNMP is greatl

This article explains the Zabbix monitoring of Dell Compellent storage devices through the SNMP protocol.The monitoring of the idea and monitoring network equipment is the same: first determine whether the device supports SNMP protocol, if supported, the next step to get the device's private MIB library, usually to the manufacturers to obtain or download online. If you do not get the MIB library, the value

The SNMP protocol contains many protocols and command applications. Now let's introduce this content. First, let's take a look at the basic concepts of SNMP. The Common commands will be explained later.
Simple Network Management Protocol (SNMP) is a Simple Network Management Protocol. It provides a framework for the Network Management system to manage the underlying Network. The SNMP protocol is widely used in many types of network devices, software, and systems, mainly because it has the follow
address because the Internet runs the TCP/IP protocol, but this is not the case.
SNMP is designed to be Protocol Independent, so it can be used on IP, IPX, appletalk, OSI, and other transport protocols used.
SNMP is a series of protocol groups and specifications (see the table below) that provide a way to collect Network Management Information from devices on the network. SNMP also provides a way for devices to report problems and errors to network management workstations.
