SNMP Community String

An SNMP community string is a password that allows devices to communicate with each other and access a device's statistics:

• Purpose: A security password that controls access to a device's statistics
• How it works: A user sends the community string along with a GET request to access a device's statistics
• Types: There are three types of community strings: read-only, read-write, and trap
• Use: SNMP community strings are used by devices that support SNMPv1 and SNMPv2c
• Default: Most devices come with a default community string, often set to "public"
• Importance: It's important to change the default community string to maintain device and network security

Network managers typically change the default community string to a customized value during device setup. The community string can be set using CLI, or modified through Enterprise Device Manager (EDM) if the user has read/write/all access authority.
