About Port 161
SNMP is used for monitoring and managing network devices such as routers, switches, servers, and printers. It provides a standardized framework for collecting device information.
Security NotesSNMP v1 and v2c use community strings (effectively passwords) transmitted in plaintext. Use SNMPv3 with authentication and encryption. Default community strings like "public" and "private" should be changed immediately.
