How to resolve Win7 bind gateway IP and MAC address display ARP entry failed to add

Failure diagram:

　Solution steps:

1, open a Command Prompt window, then enter netsh i show in, then return to, and then find the "local connection" corresponding to "IDX" (Small series Here is "11", so the following neighbors numbers are consistent here. )

2, then continue to enter in cmd: netsh-c "I i" Add neighbors 11 "Gateway IP" "MAC Address", here 11 is the IDX number.

3, and then use the ARP-A command to look at it will find that has been bound well;

Similarly, arp-d can not completely remove bindings on Win7, you must use the netsh-c "I" Delete neighbors IDX (IDX to the appropriate number) to remove the MAC address bindings.

1 Enter arp-a command to view the MAC network card Physical address of the gateway

2) Enter the netsh i show in command to view the IDX number of the local connection

3 Input Netsh-c "I i" add neighbors local connection idx "Gateway IP" Gateway MAC command Binding

4) Input ARP-A View results
