What is difference between SNMP v1 v2 and v3?

SNMP version 2c: in practical terms, v2c is identical to version 1, except it adds support for 64 bit counters. This matters, especially for interfaces. ... SNMP version 3: adds security to the 64 bit counters. SNMP version 3 adds both encryption and authentication, which can be used together or separately.

Which of the following is the main difference between SNMPv3 and SNMPv2?

SNMPv2, which is a revised version of the SNMPv1. It contains improvements in performance, confidentiality, security, and communications between managers. ... SNMPv3, which has added cryptographic security and new concepts, terminology, remote configuration enhancements, and textual conventions.

What is SNMP v1?

SNMPv1 is the oldest and original version of the SNMP protocol, supporting 32-bit counters. SNMP v1 biggest flaw is its use of a clear-text community string, which is used to identify the device and forms a very primitive style of authentication.

What is SNMP v2?

Simple Network Management Protocol version 2 (SNMPv2) is an Internet standard protocol used for managing computers and devices on an IP network. These devices include routers, switches, servers, workstations, enterprise-grade racks and many others.

Can SNMP V2 and v3 coexist?

Yes, SNMP v2 and v3 can coexist.

Is SNMP V2 secure?

SNMPv3 replaces the simple/clear text password sharing used in SNMPv2 with more securely encoded parameters. All versions run over the User Datagram Protocol (UDP). Simply using SNMPv3 is not enough to prevent abuse of the protocol.

Are used by SNMP?

SNMP is an application layer protocol which uses UDP port number 161/162. SNMP is used to monitor the network, detect network faults and sometimes even used to configure remote devices.

What is SNMP trap used for?

SNMP trap is a popular mechanism used to manage and monitor devices' activities across a small or a global network. Routing platforms are capable of generating a range of events that can be highly useful to the network administrators.

What is MIB in networking?

A management information base (MIB) is a database used for managing the entities in a communication network. ... The software that performs the parsing is a MIB compiler. The database is hierarchical (tree-structured) and each entry is addressed through an object identifier (OID).

Is SNMP a TCP or UDP?

Protocol details. SNMP operates in the application layer of the Internet protocol suite. All SNMP messages are transported via User Datagram Protocol (UDP). The SNMP agent receives requests on UDP port 161.

What are the 3 elements of SNMP?

SNMP consists of three key components: managed devices, agents, and the network management station (NMS).

Why is SNMP insecure?

SNMP is inherently insecure because SNMP messages are not encrypted. ... The easiest way to deal with SNMP threats is to set your firewall to block UDP ports 161 and 162 (and any other port you may have custom-configured for SNMP traffic) to the outside world.
