Arp Cache Life

Is there is a way to extend the Arp Cache Life for Win
95 like there is in NT?  The default is only two minutes which is much shorter than other stacks I have worked with.  On large subnets where users typically have sessions going to multiple hosts, Arp broadcasts start to become
excessive.

You may not be able to extend the time, but you can make them permanent, s othey are not removed.

Add the Switch  -s  Adds and entry in the ARP cache to associate the IP address xxx.xxx.xxx.xxx with the physical address given in 6 hexadeciaml bytes seperated by hyphens.  The IP address is specified using dotted deciaml notation (as I showed above.) The entry is permanent, and will not be removed from the cache after timeout expires.

command:

 arp -s 192.168.1.2  08-00-AB-12-EF-12 192.168.1.54

The last address was the IP (optional) address of the interface for which the address translation table should be modified. If not present, the first applicable interface will be used.

I hope this helps.. I didn't find any data on extending the timer as far as Win95 was concerned.

Thanks for the response but I was aware of this option.  We would have to create a different batch file for each subnet, or have a master batch file with an arp command for each static address on every subnet.  Both options are a support problem.  Also, our login process is already very ugly and lengly. To converge on changes users would have to run an update or login again.  Gratuitous arps are the standard way for dynamic entries to be updated before they time out.

You asked if there was a way. I went through 6 books, Technet for November 97, and called several friends that work in the business. The best answer I can come up with is no, not one of the references I've used mentions it or knows of it under Win95.
I imagine you will have to leave this answer until someone has proof to the contrary, after all, you did ask a yes/no question, and had the answer been yes I would have explained it more fully.
