mac-address-table static是对VLAN中的所有端口生效,这个MAC在这个VLAN中只能通过绑定的这个口访问,其它口是不能访问的。 swithport port-security mac-address sticky只对特定的一个端口生效,只要这个端口相连的PC的MAC不是对应的,就禁止访问。而如果接入其它口,则访问正常。 问题2、switchport port-security mac-add...
Although Cisco switches dynamically build the MAC address table by using the MAC source address of the received frames, you can also specify a static address to add to the MAC address table. The static MAC entries are retained even if the switch is restarted. To configure a static MAC addres...
A router to generate some traffic and a switch to look at (and configure) the MAC address table. Here’s the configuration: R1(config)#interface fastEthernet 0/0 R1(config-if)#no shutdown R1(config-if)#ip address 192.168.12.1 255.255.255.0 SW1(config)#interface vlan 1 SW1(config-if)...
Static MAC Address Support for Service Instances and PseudowiresCisco IOSNXOS Software
This approach significantly enhances network security, it involves a substantial administrative burden when static IP addresses are used, as each static IP and its corresponding MAC address must be manually added to the DHCP Snooping binding database. This task is labor-intensive and error-prone, es...

In order to configure a static DHCP binding you will need to configure your DHCP server to allocate the address based on some physical parameter, e.g. MAC address or maybe a client-ID (mostly used on Cisco devices). Elvin Message was edited by: Elvin Arias Expand Post LikeReply Log In ...
