This essay will explain in detail the Linux network Card Advanced command, IP alias and Linux under the multi-NIC binding knowledgeFirst, the Network card Advanced commandIn a previous essay, the Linux Learning CentOS (ix)--LINUX System network environment configuration, detailed explained the Linux system under the network environment configuration and so on the knowledge, we have learned some basic commands about the network configuration. Some of the advanced commands for network cards in Lin

on the remote terminal, you can put 2 commands together to execute.To set up a virtual network card, you need to change the network card configuration file name to Ens33:0,ip address change one.Added virtual network card IP also can be ping through the ↑[[email protected] network-scripts]# Mii-tool ENS33 See if the network cable is connected[[email protected] network-scripts]# Ethtool Ens33 can also see if the NIC is connected[[email protected] netwo

Whether the correctness and timing of data can be ensured requires further careful tests. 2. fault tolerance mode of the network adapter (mode = BOND_MODE_ACTIVEBACKUP) The configuration method of the fault tolerance mode is similar to that of the load balancing mode. you just need to modify/etc/modprobe. conf.

You can view bond0's working Status query to learn about the working status of bonding in detail.

starts, you can add a line in the configuration file:/etc/modules. conf: 　　 Alias net? Pf? 10 ipv6 # automatically load IPv6 module on demand 　　 　　 4. Adjust the NIC Working Mode 　　 Currently, most network interfaces work in adaptive mode. When configuring network interface parameters, we seldom consider the network interface mode. Sometimes we find that some network interface modules have been loaded, but they are unstable in some modes. For example, I use a miscellaneous brand of XXX. 　　 The

For example, the traffic control frame also needs to be recognized and executed by the Mac directly.

Label: reset F4 dp83848 As early as before graduation, I had debugged stm32f407 + dp83848. This debugging took another two days. Stm32 supports two industrial standard interfaces to connect to the external physical layer's PHY module. They are media-independent interfaces (MII) and simplified interfaces (rmii ). In the previous MII mode used by the PHY chip, the current rmii mode is used for this debuggin
