Cisco思科交换机show mac address-table命令使用详解

show mac address-table命令用于显示交换机的MAC地址表。

该表记录了每个接口和与之关联的MAC地址。

#show mac address-table ?    --当在默认情况下输入“?”,系统会自动识别为 help 命令。

  address       Address to lookup in the table               --要查找的MAC地址

  aging-time    MAC address table aging parameters  --MAC地址表老化参数

  count         Number of MAC addresses in the table  --MAC地址数

  dynamic       List dynamic MAC addresses               --列出动态MAC地址

  interface     List MAC adresses on a specific interface --列出特定接口上的MAC地址

  learning      Display learning on VLAN or interface   --在VLAN或接口上显示学习

  move          MAC Move information                          --MAC移动信息

  multicast     List multicast MAC addresses               --列出多播MAC地址

  notification  MAC notification parameters and history table  --MAC通知参数和历史表

  protocol      protocol keyword  

  secure        List secure MAC addresses                  --列出安全MAC地址

  static        List static MAC addresses                       --列出静态MAC地址

  vlan          List MAC addresses on a specific vlan   --列出特定vlan上的MAC地址

  |             Output modifiers                                        --输出修饰符

 

show mac address-table address   通过MAC地址追踪设备经过的端口

#show mac address-table address 0040.544d.873d

show mac address-table | include 通过输入的关键词进行模糊查询

keyword 关键字可以是MAC地址、MAC地址中的一部分，一般建议搜索末尾后四位，基本上是唯一的。

#show mac address-table | include 0040.544d.873d

 7    0040.544d.873d   dynamic ip,ipx,assigned,other GigabitEthernet6/48

#show mac address-table | include 873d

 7    0040.544d.873d   dynamic ip,ipx,assigned,other GigabitEthernet6/48

keyword 关键字也可以是端口号或端口号中的一部分

#show mac address-table | include GigabitEthernet6/48

 7    0040.544d.873d   dynamic ip,ipx,assigned,other GigabitEthernet6/48

#show mac address-table | include 6/48

 7    0040.544d.873d   dynamic ip,ipx,assigned,other GigabitEthernet6/48
