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 <mac> 通过MAC地址追踪设备经过的端口
#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。

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
