Cisco思科交換機show mac address-table命令使用詳解

show mac address-table命令用于顯示交換機的MAC地址表。
該表記錄了每個接口和與之關(guān)聯(lián)的MAC地址。

#show mac address-table ?? ? --當(dāng)在默認情況下輸入“?”,系統(tǒng)會自動識別為 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地址表老化參數(shù)
? count ? ? ? ? Number of MAC addresses in the table? --MAC地址數(shù)
? dynamic ? ? ? List dynamic MAC addresses? ? ? ? ? ? ? ?--列出動態(tài)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或接口上顯示學(xué)習(xí)
? move ? ? ? ? ?MAC Move information? ? ? ? ? ? ? ? ? ? ? ? ? --MAC移動信息
? multicast ? ? List multicast MAC addresses? ? ? ? ? ? ? ?--列出多播MAC地址
? notification ?MAC notification parameters and history table? --MAC通知參數(shù)和歷史表
? protocol ? ? ?protocol keyword??
? secure ? ? ? ?List secure MAC addresses? ? ? ? ? ? ? ? ? --列出安全MAC地址
? static ? ? ? ?List static MAC addresses? ? ? ? ? ? ? ? ? ? ? ?--列出靜態(tài)MAC地址
? vlan ? ? ? ? ?List MAC addresses on a specific vlan? ?--列出特定vlan上的MAC地址

? <cr>

show mac address-table address <mac>??通過MAC地址追蹤設(shè)備經(jīng)過的端口

#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> 通過輸入的關(guān)鍵詞進行模糊查詢

keyword 關(guān)鍵字可以是MAC地址、MAC地址中的一部分，一般建議搜索末尾后四位，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 關(guān)鍵字也可以是端口號或端口號中的一部分

#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

show interfaces G6/48?顯示交換機端口G6/48的端口配置信息

#show interfaces G6/48
