attribute defines the name of a specific object, such as sysUpTime. It is just a tag. When representing data, SMI uses ASN.1 (Abstract Syntax Notation One ). The object must be "identified ". For the Internet management MIB, the identifiers expressed in the ASN.1 notation start with the following:
Internet object identifier ::={ iso org (3) dod (6) 1}
Or use a simple format: 1.3.6.1
This is extracted from the ASN.1 document. It defines a tree format

1. Definition:The TCP/IP model is also known as the DoD model (Department of Defense models). TCP/IP literally represents two protocols: TCP (Transmission Control Protocol) and IP (Internetwork protocol).The TCP/IP protocol is not a collectively known protocol for TCP and IPs, but rather refers to the entire TCP/IP protocol family. In terms of the Protocol layering model, TCP/IP consists of four levels: network interface layer, network layer, Transpor

Ii. Initial settings of Sniffer Pro
Sniffer Pro needs to capture packets, but too much information is captured. How can we start to filter when capturing? Set the following parameters: "capture"-"define filter"-"Address"-"Address type", and "location 1" to "10.66.1.188 ", enter "10.66.0.1" in "Location 2" and click "OK. 1.

This is much simpler. We will define the filter so that we can freely use the Sniffer Pro software.
