如何查看ARP缓存表
ARP缓存表是可以查看的，也可以添加和修改。在命令提示符下，输入“arp -a”就可以查看ARP缓存表中的内容了。用“arp -d”命令可以删除ARP表中某一行的内容；用“arp -s”可以手动在ARP表中指定IP地址与MAC地址的对应。 Microsoft Windows XP [版本 5.1.2600]

Displays and modifies the IP-to-Physical address translation tables used by
address resolution protocol (ARP).
ARP -s inet_addr eth_addr
ARP -d inet_addr
ARP -a [-N if_addr]
-a Displays current ARP entries by interrogating the current
protocol data.If inet_addr is specified, the IP and Physical
addresses for only the specified computer are displayed.If
more than one network interface uses ARP, entries for each ARP
table are displayed.
-g Same as -a.
inet_addr Specifies an internet address.
-N if_addr Displays the ARP entries for the network interface specified
by if_addr.
-d Deletes the host specified by inet_addr. inet_addr may be
wildcarded with * to delete all hosts.
-s Adds the host and associates the Internet address inet_addr
with the Physical address eth_addr.The Physical address is
given as 6 hexadecimal bytes separated by hyphens. The entry
is permanent.
eth_addr Specifies a physical address.
if_addr If present, this specifies the Internet address of the
interface whose address translation table should be modified.
If not present, the first applicable interface will be used.
Example:
> arp -s 157.55.85.212 00-aa-00-62-c6-09.... Adds a static entry.
> arp -a .... Displays the arp table.
