一、查看系统MAC

1）盒式交换机：

display bridge mac-add System bridge MAC address: xxxx-xxxx-xxxx

2）框式交换机：

display system-mac MAC-num      :1 Index         MAC Addr ---------------------------- default       xxxx-xxxx-xxxx current       xxxx-xxxx-xxxx

二、查看接口MAC

display interface GigabitEthernet0/0/10 GigabitEthernet0/0/10 current state : UP Line protocol current state : UP Description: Switch Port, Link-type : trunk(configured), PVID :    1, TPID : 8100(Hex), The Maximum Frame Length is 1600 IP Sending Frames' Format is PKTFMT_ETHNT_2, Hardware address is xxxx-xxxx-xxxx Current system time: 2015-03-02 10:50:43+08:00 Port Mode: COMMON COPPER Speed : 1000,   Loopback: INTERNAL Duplex: FULL,   Negotiation: DISABLE Mdi   : AUTO,   Flow-control: DISABLE Last 300 seconds input rate 480 bits/sec, 0 packets/sec Last 300 seconds output rate 480 bits/sec, 0 packets/sec Input peak rate 13880 bits/sec, Record time: 2015-02-19 17:09:47 Output peak rate 13880 bits/sec, Record time: 2015-02-19 17:09:47 Input:  510225 packets, 80014227 bytes   Unicast:                          0,  Multicast:                      510225   Broadcast:                        0,  Jumbo:                               0   Discard:                          0,  Pause:                               0   Frames:                           0   Total Error:                      0   CRC:                              0,  Giants:                              0   Jabbers:                          0,  Fragments:                           0   Runts:                            0,  DropEvents:                          0   ---- More ----

三、查看设备学习到的mac表项

1）查看整机所有类型mac地址表项：

display mac-address 

2）查看某端口下mac地址表项：

display mac-address GigabitEthernet 0/0/X

3）查看系统所有动态MAC地址表项：

display mac-address dynamic

此处dynamic可以替换为blackhole、static、security、sticky、summary分别查看黑洞MAC、静态MAC、安全动态MAC、sticky MAC、MAC表项汇总信息。

由于内容较多，此处不再赘述；
