工作需要,学习了Cisco的路由器配置,记一下:

  • 查看所有信息
1
show run
  • 查看span
1
show span
  • 为某个vlan id建立spanning-tree
1
spanning-tree vlan 15
  • 取消某个vlan id的spanning-tree
1
no spanning-tree vlan 15
  • 将某个端口加入vlan中
1
2
3
sh run init gi 0/39
config t
switchport access vlan 14
  • 保存配置

2
do wr
copy running-config startup-config

顺便记一下cisco catalyst交换机配置

  • 登陆交换机
1
ssh admin@10.1.0.2
  • 查看现有配置
1
show running-config
  • 批量修改vlan:端口37-39改成vlan15。端口41-46改成trunk

(config-if-range)#sw tr e d
