为特定接口添加 Arp 条目 [Windows]

Question

I know that we can add arp entry in windows using arp -s IP MAC I need a command to add such entry for a specific interface if I have many

While I have those two interfaces Interface: 10.243.16.11 --- 0xe Interface: 192.168.1.179 --- 0x17

Answer 1

The arp command under Linux has a -i flag for specifying the interface but the Windows one is slightly different.

If you run arp on its own, you'll see how to do it:

ARP -s inet_addr eth_addr [if_addr]
ARP -d inet_addr [if_addr]
ARP -a [inet_addr] [-N if_addr] [-v]

You need to provide the IP address if_addr for the specific interface you want to affect. For example:

C:\Users\Pax>arp -a

Interface: 192.168.0.72 --- 0x1c
  Internet Address      Physical Address      Type
  192.168.0.1           80-20-da-a0-f9-3d     dynamic

Interface: 172.23.128.1 --- 0x33
  Internet Address      Physical Address      Type
  172.23.143.255        ff-ff-ff-ff-ff-ff     static

C:\Users\Pax>arp -s 192.90.90.90 80-20-da-a0-f9-33 172.23.128.1

C:\Users\Pax>arp -a

Interface: 192.168.0.72 --- 0x1c
  Internet Address      Physical Address      Type
  255.255.255.255       ff-ff-ff-ff-ff-ff     static

Interface: 172.23.128.1 --- 0x33
  Internet Address      Physical Address      Type
  172.23.143.255        ff-ff-ff-ff-ff-ff     static
  192.90.90.90          80-20-da-a0-f9-33     static

You can see there that the arp entry has been added to the cache for the specific interface.
