dis mac-address

  1. Display the routing table of the switch

Use the dis ip routing-table command to display the routing table of the switch, that is, the routing table supported by the switch routing information. For example:
dis ip routing-table

  1. Display the system log of the switch

Use the dis logbuffer command to display the system log information of the switch, including system events and interfaces Status changes, fault alarms, etc. For example:
dis logbuffer

  1. Display the ARP table of the switch

Use the dis arp command to display the ARP table of the switch, that is, the IP address currently learned by the switch and the Correspondence of MAC addresses. For example:
dis arp

It should be noted that the specific usage of the dis command may vary according to different models and versions of switches. Users should pay attention to the relevant device documentation and Guide to ensure proper use of the dis command for inspection and troubleshooting.

To sum up, the dis command is a commonly used command in switch inspection. This command can display the switch configuration information, operating status, etc., and help administrators perform device inspection, troubleshooting, and fault location. Work. Correct use of the dis command can improve the maintenance efficiency and reliability of network equipment and ensure the normal operation of the network.

New breakthrough! State Grid Jingzhou Power Supply Company uses fixed-wing drones for the first time to inspect ultra-high voltage transmission lines New breakthrough! State Grid Jingzhou Power Supply Company uses fixed-wing drones for the first time to inspect ultra-high voltage transmission lines Aug 18, 2023 pm 05:05 PM

A 1.6-meter-long and 2.4-meter-wide fixed-wing drone of the State Grid Jingzhou Power Supply Company recently successfully completed the inspection mission of 1,000 kV, 800 kV, and 500 kV ultra-high voltage transmission lines in Songzi and Jianli areas. This breakthrough marks another new progress in the company's drone application. In order to prepare for inspections, the company carefully surveyed and analyzed the UHV line channel environment in advance, determined the take-off and landing points of each line, and completed route planning. At this critical stage, the staff fully considered various complex factors such as terrain, climate, route direction, etc. to ensure the accuracy and safety of the route. During the trial, the fixed-wing UAV demonstrated excellent performance at high altitudes and in harsh environments. performance. It is equipped with high-definition visible light and lidar devices, which can

Broadcom Unveils Innovation, Launches Industry's First On-Chip Neural Network Switch Broadcom Unveils Innovation, Launches Industry's First On-Chip Neural Network Switch Dec 03, 2023 pm 08:51 PM

Broadcom recently announced the launch of the Trident5-X12 chip, which is equipped with a new NetGNT (Network General Neural Network Traffic Analyzer) on-chip neural network inference engine. NetGNT is different from traditional packet processing. It can work in parallel to enhance standard packet processing. pipeline. Traditional pipelines can only process one packet/path at a time, while NetGNT, as a machine learning inference engine, can be trained to identify various traffic patterns across the entire chip. It is understood that the Trident5-X12 chip has powerful software programming functions and on-site upgrade functions, providing a bandwidth of up to 16.0 Terabits/second, which is twice that of Trident4-X9. In addition, the new chip also supports

The working principle of the switch includes: 1. Data frame reception and analysis; 2. Forwarding table update; 3. Data frame forwarding; 4. Flood processing; 5. Connection maintenance. Detailed introduction: 1. Data frame reception and parsing. When the switch receives a data frame, it will first parse the data frame and extract the source MAC address and destination MAC address and other information; 2. Update of the forwarding table, The switch maintains a forwarding table internally, which records the correspondence between MAC addresses and interfaces; 3. Forwarding of data frames, etc.

How does a switch work? How does a switch work? Dec 26, 2023 pm 02:07 PM

The working principle of the switch is based on the second layer of the OSI reference model, the data link layer. A switch is a network device based on a learning process that enables communication between different devices in the network by parsing and forwarding data frames. The switch can continuously improve the contents of its internal forwarding table, improve the efficiency and reliability of data exchange, and ensure the stability and security of the connection. Switches are widely used in enterprise networks, data centers, campus networks and other scenarios to provide stable and efficient connection services for various applications.

What is the difference between a switch and a router What is the difference between a switch and a router Jan 16, 2024 pm 03:39 PM

Differences: 1. Different working principles: The switch works at the relay layer and is mainly addressed based on MAC address. The router works at the network layer, addresses according to the IP address, and can handle the TCP/IP protocol; 2. Different functions: the switch can make multiple computers connected to it form a local area network, but it cannot automatically identify the address where the data packet is sent and arrived. The router is responsible for automatically identifying the addresses where data packets are sent and arrived, and can handle the routing of data packets; 3. Different usage scenarios: Routers are usually used for sending and receiving in one place. A switch is used to connect multiple computers.
