Mac binding process of and H3C low-end switches

Three-tier devices can be IP and Mac binding, but a large number of that is sacrificing the cost of equipment performance, and sometimes attacks and network failures are easy to cause greater trouble. Moreover, the price of three-tier equipment is not all enterprises can buy at will.

How to do Mac binding on two-tier low-end products to prevent the impact of ARP on the network.

Step One: Enter port set E0/8 Port Mac learning number set to 0 (red for commands and parameters that must be entered manually)

[S2126-ei]int e 0/8

[s2126-ei-ethernet0/8]mac-address Max-mac-count 0

[S2126-ei-ethernet0/8]q

Step two: Bind the 0015-58aa-3650 to the E0/8 port, at which point only the Mac-bound PC can surf the internet, while E0/8 belongs to VLAN 2004

[S2126-ei]mac static 0015-58aa-3650 int E0/8 VLAN 2004

Last step: Save the configuration

[S2126-ei]q

This would save the configuration in the flash memory.

The switch configurations'll is written to Flash.

The other steps are the same for H3C low-end switches, but the first step is a little different.

Step One: Enter port set E1/0/8 Port Mac learning number set to 1 (red for commands and parameters that must be entered manually)

[H3C s2126-ei]int e 1/0/8

[H3C s2126-ei-ethernet1/0/8]mac-address Max-mac-count 1

[H3C S2126-ei-ethernet1/0/8]q Press a carriage return to be done

Step two: Bind the 0015-58aa-3650 to the E1/0/8 port, at which point only the Mac-bound PC can surf the internet, while E1/0/8 belongs to VLAN 2004

[h3c s2126-ei]mac static 0015-58aa-3650 int E1/0/8 VLAN 2004

Last step: Save the configuration

[H3C s2126-ei]q

<H3C S2126-ei>save

This would save the configuration in the flash memory.

Remember to press two times to enter OH.

It feels good to use, but it is not a batch of Oh, if you want to bind more than one Mac corresponding port, it will not work, the bottom of the PC will not pass the OH; may be the reason for the low end of the switch; you only have to be honest one by one.

Note: The two command order cannot be reversed unless the PC is not connected under the port.
