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 ?    --当在默认环境下输入“?”,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 <mac>  通过MAC地址追踪装备颠末的端口

#show mac address-table address 0040.544d.873d
Unicast Entries
 vlan   mac address     type        protocols               port
-------+---------------+--------+---------------------+--------------------
 732    0040.544d.873d   dynamic ip,ipx,assigned,other GigabitEthernet6/48
show mac address-table | include <keyword> 通过输入的关键词举行含糊查询

keyword 关键字可以是MAC地址、MAC地址中的一部门，一般发起搜刮末尾后四位，根本上是唯一的。
#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门
#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
show interfaces G6/48 显示交换机端口G6/48的端口设置信息
