Snmp mib is a major module of SNMP protocol software. Therefore, the main function of MIB is the Management Information Library, we have also discussed some of the previous articles, but many of our friends still do not understand snmp mib. For this reason, we have compiled the following articles to help you learn this part 。
Some servers and devices have been mo
Security has always been a key topic in the network. So here we will emphasize the security of the SNMP service. So how to implement security protection for the SNMP service? This article provides the following details for your reference.
When using the SNMP service, pay attention to its security. Therefore, in the operation, ensuring the security of the
The SNMPv3 security header uses user-safe mode (USM), which provides network management communications with confidentiality and integrity. Confidentiality is provided through the adoption of data encryption standards (DES). Although this algorithm is known for its fragility (since it employs a 40-bit key), it has significant advantages over plaintext community strings. Even a fragile algorithm like des can be compromised by a concerted attack, so you could at least guard against accidental eaves

Introduction to SNMP
At present, the most widely used network management protocol in the network is SNMP (Simple network Management Protocol, Easy Network Management Protocol). SNMP is widely accepted and put into use industrial standards, to ensure that the management information in the network at any two points between the transmission, easy to network adminis

1. The relationship between the IP address and the MAC address in the ARP table of the layer-3 device.
2. the forwarding bridge table of the L2 device stores the correspondence between MAC and forwarding ports.
3. CDP (Cisco Discovery Protocol) is the link layer protocol for discovering adjacent devices between Cisco devices.
4. The forwarding table in the layer-2 module of a layer-3 switch is implemented in a cam table, such as show Cam dynamic.
