SND/ONC Collection ccie sp 4.1 lab topology

1. Question: What is the difference between the SDN Cloud Campus Access Mode and the Kernel Mode? Answer: Access mode: Using a port security scheme, legitimate users form static ip+mac bindings on the port.      Gateway mode: Turns off dynamic arp learning capabilities and legitimate users adopt static arp bindings. 2. Question: Does the SDN need to change the IP address of the cluster IP before it can be authorized before it can be authorized? Answer: Needed 3. Question: Access control and under what circumstances will be on the pending list Answer: (1) First access      (2) IP conflict      (3) IP/VLAN inconsistencies      (4) IP changes      (5) Position change      (6) Gateway ARP spoofing 4. Question: Access control kernel mode and gateway device receives the ARP information of the unadmitted terminal, how to ...

LACP technology explained

Image
In short, Link Aggregation technology is to aggregate multiple physical links into a logical link with a higher bandwidth. The bandwidth of the logical link is equal to the sum of the bandwidth of the aggregated multiple physical links. The number of aggregated physical links can be configured according to the bandwidth requirements of the service. Therefore, link aggregation has the advantages of low cost and flexible configuration. In addition, link aggregation also has the function of link redundancy backup, and the aggregated links dynamically backup each other, which improves the stability of the network.   There was no uniform standard for the realization of early link aggregation technology. Each manufacturer had its own proprietary solutions, which were not completely the same in function and incompatible with each other. Therefore, the IEEE has specially formulated a standard for link aggregation. The current official standard for link aggregation technology is IEEE Standa...

How to understand the difference between Layer 3 switching and routers

I have learned network technology for a long time, but what is the difference between a Layer 3 switch and a router? Many people will still be confused. So what is the difference between them, we need to understand it carefully. The simplest working principle of Layer 2 switches is to perform data forwarding operations based on the MAC address table. There are four basic functions:  learning, forwarding, broadcasting and updating. When a data frame is received, the switch will store the mapping relationship between the source MAC address of the data frame and the corresponding port number in the MAC address table for subsequent data forwarding. However, in this line of data forwarding, the target MAC address is used, and the MAC address table is queried. If the MAC address table has a corresponding mapping relationship, the data frame will be unicast forwarded. If there is no corresponding mapping relationship, a generalization will be performed. flood. Another very importan...
