The command syntax in the early OS version of Huawei equipment is almost the same as that of Cisco\x0d\After losing the lawsuit with Cisco, the command syntax was changed. After all, naked plagiarism will not work...\x0d\ There are many network equipment manufacturers on the market, but if you understand the Cisco, Huawei, h3c, Nortel and other equipment you are talking about, the others are just like changing the soup without changing the medicine\x0d\\x0d\ If you study, use Cisco Huawei h3c Juniper is the main one\x0d\\x0d\Hope it helps you
