1. Recently, I encountered a strange thing when I configured adsl dialing on linux. When adding vlan to linux, the VLAN Dev name of vlan normally ends with [network card .xx]. As a result, mine ends with [renamexx], which is directly above the figure. figure 1 shows the configuration of the normal machine, and figure 2 shows the configuration of my abnormal machine.

configure vlan is to find tutorials on the Internet, google, baidu have searched all over but did not encounter this kind of situation, but also ask God to give me advice.
