What is used to manage network devices like printers and routers?

The Simple Network Management Protocol (SNMP) is specifically designed for managing and monitoring network devices such as printers, routers, switches, and servers. It operates using a client-server model where network devices (agents) respond to requests from the management system (manager). Through SNMP, administrators can retrieve information about device status, performance metrics, and configuration settings, as well as set parameters and troubleshoot issues remotely.

SNMP is particularly beneficial in large networks that require centralized management of various devices. Its efficiency in polling devices for status updates allows IT personnel to maintain optimal performance and resolve issues proactively. The protocol facilitates the collection of statistics and operational data, enabling effective performance monitoring and network management.

In contrast, the other options serve different purposes:

• ICMP (Internet Control Message Protocol) is primarily used for diagnostic and control purposes, such as error reporting and troubleshooting network connectivity.

• SSH (Secure Shell) is a protocol used to securely access and manage devices over a network but does not provide management of the devices in the same way SNMP does.

• HTTP (Hypertext Transfer Protocol) is utilized for transferring hypertext documents on the web and is not inherently designed for direct device management.
