5.6.2 Global Configuration
1. Overview
The purpose of global configuration is to enable the SNMP service and make the SNMP
protocol version (v1/v2c/v3) take effect, so as to achieve basic configuration of local port,
device location, and contact information.
SNMP v1: As the earliest version of SNMP, SNMP v1 has poor security, and only supports
simple community string authentication. SNMP v1 has certain flaws, such as plaintext
transmission of community strings and vulnerability to attacks. Therefore, SNMP v1 is not
recommended for modern networks.
SNMP v2c: As an improved version of SNMP v1, SNMP v2c supports richer functions and
more complex data types, with enhanced security. SNMP v2c performs better than SNMP
v1 in terms of security and functionality, and is more flexible. It can be configured
according to different needs.
SNMP v3: As the newest version, SNMP v3 supports security mechanisms such as
message authentication and encryption compared to SNMP v1 and SNMP v2c. SNMP v3
has achieved significant improvements in security and access control.
