链路聚合(Eth-Trunk), 通过将多条以太网物理链路捆绑在一起，形成一条逻辑链路。有三大优势可以 增加带宽， 提升系统可靠性（即使部分链路出现故障，流量可以切换到其他链路上），负载均摊 。

重要知识点 多条物理链路聚合后

  1. 总带宽等于原来的多条物理链路带宽总和。
  2. 多条物理链路互相备份，当某条链路出现故障后，流量可以切换到其他链路上。
  3. 流量可以负载均摊。

LACP(Link Aggregation Control Protocol) 链路聚合模式可以

华为交换机配置telnet 登录的脚本

interface g0/0/1
port link-type trunk
port trunk allow-pass vlan 5

华为交换机查看telnet 是否开启

display telnet server status
Info: The Telnet server has been enabled.
[Huawei]display telnet server status
 TELNET IPv4 server                       :Enable
 TELNET IPv6 server                       :Enable
 TELNET server port                       :23

开启telnet

telnet server enable

关闭telnet

undo telnet server enable

修改telnet 端口

telnet server port ?
  INTEGER<23,1025-55535>  Set the port number, the default value is 23
  1. 1
  2. 2
