SNMP Configuration Types
There are two different SNMP Configuration Types: Read-only and read-write community strings are used by SNMP to exchange data. Both of them can be set up to allow public access or to forbid unauthorized alterations.
- Read: Any software or hardware capable of speaking SNMP can read the read strings.
- Read-Write: The read-write SNMP string enables the setting or manipulation of values, such as the settings of a device.
SNMP in Wireshark
The Internet Architecture Board (IAB) defined the Simple Network Management Protocol (SNMP) as an application-layer protocol for transmitting management data between network devices in RFC1157. It belongs to the TCP/IP (Transmission Control Protocol/Internet Protocol) protocol family. One of the extensively used network protocols for managing and watching over network components is SNMP. The majority of network components of professional qualifications include an integrated SNMP agent. To connect with the network monitoring tools or network management system, these agents must be activated and set up (NMS). UDP is frequently used by SNMP as its transport protocol. 161 (SNMP) and 162 are well-known UDP ports for SNMP traffic (SNMP TRAP). Additionally, it is compatible with TCP, Ethernet, IPX, and other protocols. The ILMI (Integrated Local Management Interface) protocol used by ATMs is SNMP.
