Arp Cache

[Jackie]

Hello all,

Having a problem with flushing arp cache when repairing connection. I found
the commands 'arp -d *' and 'netsh interface ip delete arpcache' but which
to use. Could someone please explain the functional difference of these
commands?

Thankyou.

[Ken Wickes [MSFT]]

I doubt there is any difference. I also doubt that you arpcache is causing
you any problems beyond the error message.

Thanks for the help Ken. I found that the repair option performs these
actions

Dynamic Host Configuration Protocol (DHCP) lease is renewed: ipconfig /renew
Address Resolution Protocol (ARP) cache is flushed: arp -d *
Reload of the NetBIOS name cache: nbtstat -R
NetBIOS name update is sent: nbtstat -RR
Domain Name System (DNS) cache is flushed: ipconfig /flushdns
DNS name registration: ipconfig /registerdns

I suppose 'arp -d *' is the one to use. I would still like to understand
what 'netsh interface ip delete arpcache' does that's different. Both
commands run OK but the error message remains. Do you know why the error
message may occur?

'netsh interface ip delete arpcache' is used to rebuild the TCP/IP stack.
arp -d only deletes entries. If you are having an issue with TCP, you should
use netsh interface ip delete arpcache, which flushes the cache.
Technically, deleting entries is not the same as flushing the cache, but the
MS documentation is vague on this point. All it says is that the command is
used to reset the TCP/IP stack to a pristine state.

"With the NetShell utility, you can now reset the TCP/IP stack back to a =
PRISTINE STATE, to the same state as when the operating system was =
installed"
Command Usage
netsh int ip reset [log_file_name]

I don't know why it fails. I tried to look at the code once but got lost.

It may just post an error if the arp cache is already empty. If I run
arp -d * over and over sometimes I get an error about the specified entry
not found.

Thankyou for the help Ken. I don't have any problems with the ARP cache =
other than the error so I will ignore it for now

'netsh interface ip delete arpcache' is used to rebuild the TCP/IP =

should
use netsh interface ip delete arpcache, which flushes the cache.
