(usr-tc) Recommended ip pool size.
We have a HiperARC chassis with PRI service. Can anyone give me a suggestion on what the recommended ip pool size would be for one PRI span (23 modems)? I haven't been able to find this info anywhere in any documentation.

Do you plan on expanding? If you won't be adding any modems to this box, a pool of 23 will suffice. If you think that you'll have 96 modems in the box a year from now, go ahead and give it a pool of 96 addresses if you have enough. -- Kirk Mitchell-General Manager mitch@keyconn.net Keystone Connect Unlock Your World Altoona, PA 814-941-5000 http://www.keyconn.net - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.

Depends upon your maximum number of ports. So in your case you need an ip pool of 23 address for each pri card. krish On Mon, 20 Dec 1999, Jason P. wrote:

Thanks for the info. We actually have 7 PRI's on our HiperARC, but I wanted to get a general idea of how many ip's we were looking at. We started our Hiper chassis with 4 PRI's on it and I had set the ip pool size to 140 to be safe. I now have it set to 168. We also have an old NetServer TC chassis with 2 PRI's on quads, and I remember we had to set the pool size quite a bit higher than the actual number of trunks. I just didn't know if it applied to the Hiper's also. Thanks again for the help. Jason. Tatai SV Krishnan wrote:

I would use 24 IP's per DSP. Since IP's are handed out on least used priority you would not have to worry about a person calling up, dropping and another totally different users then hooking up with the same IP and not getting anytwere because the previous IP user started a 25Mb DL. Add that 24th IP address in there. Paul Farber Farber Technology farber@admin.f-tech.net Ph 570-628-5303 Fax 570-628-5545 On Mon, 20 Dec 1999, Tatai SV Krishnan wrote:

hmmmm... Seems like a simple set of rules to assume. But, if you were in a hurt, I'd bet you could get away with the 23 per DSP card and a hand full of extra numbers for a buffer. The science would tell you that 23 per card would make it fine. But, buffers are buffers for a reason. If you have the IPs available, Paul seems to have good advice. I actually put 1 IP for each access circuit. Then, I ad a few for a safty net. I have actually run with around 20 too few before, and had only minor problems (when I maxed out - DUH!). So, it's an IP per user online ratio - that simple. But, I am only saying what has already been said a few times before. Unless someone knows a bit of information about the network capacity of these cards that would lead us to another conclusion - I am running on common sense. If there is a bug to defer through an overage in IPs, please post this ASAP. I do not want to be left out in the cold on this simple an issue. I can order IPs like anyone - and would be happy to just- ify a few hundred more than I need. (or would need if equipment were perfect).

just one? a /27 would do. But surely you will have growth right? If so, give as much as you can reasonably afford to up to say a /25. /25 is a decent size to handle 5 HDM's with not a whole lot of wasted space.
