交换笔记

交换机的端口类型有三种；  trunk  ,    hybrid  ,   access

vlan 的建立以及trunk 链路的做法:
[sw2]
[sw2]vlan 10
[sw2]vlan 20               建立vlan
[sw2]int g1/0/1
[sw2-GigabitEthernet1/0/1]port link-type trunk                   配置trunk链路
[sw2-GigabitEthernet1/0/1]port trunk permit vlan 10 20           并permit vlan 10 20
 Please wait... Done.
[sw2-GigabitEthernet1/0/1]qu
[sw2]
建立hybrid端口；
[sw2]vlan 10           
[sw2-vlan10]vlan 20                  
[sw2-vlan20]qu             
[sw2]int g1/0/3              
[sw2-GigabitEthernet1/0/3]port link-type hybrid      
[sw2-GigabitEthernet1/0/3]port hybrid vlan 10 20 untagged            能够接收 vlan 10 vlan 20 发过来的数据
 Please wait... Done.
[sw2-GigabitEthernet1/0/3]qu
[sw2]int g1/0/4
[sw2-GigabitEthernet1/0/4]port link-type  hybrid
[sw2-GigabitEthernet1/0/4]port hybrid vlan 10 20 tagged              能够接收并且能够透传vlan 10 vlan 20 发过来的数据。
 Please wait... Done.
[sw2-GigabitEthernet1/0/4]

建立access端口；
[sw2]
[sw2]vlan 40
[sw2-vlan40]
[sw2-vlan40]qu
[sw2]int g1/0/5
[sw2-GigabitEthernet1/0/5]port link-type  ac      建立access端口。
[sw2-GigabitEthernet1/0/5]port access vlan 40     这接口属于vlan 40
[sw2-GigabitEthernet1/0/5]qu
[sw2]
[sw2]
还有一种方法如下：
[sw4]vlan 50
[sw4-vlan50]qu
[sw4]int g1/0/9
[sw4-GigabitEthernet1/0/9]port link-type ac
[sw4-GigabitEthernet1/0/9]qu
[sw4]int g1/0/10
[sw4-GigabitEthernet1/0/10]port link-type  access
[sw4-GigabitEthernet1/0/10]qu
[sw4]vlan 50
[sw4-vlan50]port g1/0/9 to g1/0/10

mstp 的建立方法
[sw2]stp region-configuration    
[sw2-mst-region]reg h3c                       mst 的域名
[sw2-mst-region]rev 0                         mst 的版本号
[sw2-mst-region]instance 1 vlan 10            mst所建立的实例中所对应的vlan
[sw2-mst-region]instance 2 vlan 20
[sw2-mst-region]act region-configuration      激活mst
[sw2-mst-region]qu
[sw2]stp mode mstp                            模式为mst
[sw2]stp enable                               开启stp
[sw2]

BPDU tunnel典型配置；
[sw4]bpdu-tunnel tunnel-dmac  0100-0ccd-cdd0     配置BPDU采用的组播MAC地址
[sw4]int g1/0/24
[sw4-GigabitEthernet1/0/24]port access vlan 10     使用vlan 10 对用户传输，
[sw4-GigabitEthernet1/0/24]stp disable
[sw4-GigabitEthernet1/0/24]undo ntdp  enable          对BPDU进行透明传输
[sw4-GigabitEthernet1/0/24]bpdu-tunnel dot1q  stp
 STP BPDU tunnel starts running on interface GigabitEthernet1/0/24.
[sw4-GigabitEthernet1/0/24]
 

h3c交换acl

[sw4]time-range shangke  9:00 to 21:00 daily
[sw4]acl number 2001
[sw4-acl-basic-2001]rule 0 permit so  172.18.1.0 0.0.0.255  time-range shangke
[sw4-acl-basic-2001]qu
[sw4]traffic classifier cisco
[sw4-classifier-cisco]if-match acl 2001
[sw4-classifier-cisco]qu
[sw4]traffic behavior  h3c
[sw4-behavior-h3c]filter permit
[sw4]qos policy h3c
[sw4-qospolicy-h3c]classifier cisco behavior h3c
[sw4-qospolicy-h3c]qu
[sw4]
