Bill, -I emailed both email addresses listed on the ep.net website contact information. -I have not as of this email received a response to my request or that email from you -Jeff's email bounces since it's an @ep.net and that seems to be rejecting all mail from both tdstelecom.com and fdfnet.net -I see no fax/phone contact information listed on the ep.net website. If you provide them, I will use them. -The webpage the IX gave me to register for IP space contained no phone/fax contact information. -I attempted to contact your INOC-DBA line, it was not active. So yes, really. Could you please provide me with what we are missing to receive allocation.

Interestingly enough, the eBay prices reflect this: anything below an RSP4 or a VIP2-50 is useless junk good only for home or lab; recently bought a CX-EIP2 for $0.99 and a VIP2-40 for $50. CX-FSIPs and RSP2s go for peanuts too. However, a VIP2-50 or an RSP4 still go for 500 bucks a pop, which means they are still worthy of a production environment. As mentioned before, this is comparing apples and oranges anyway. Although this is overly simplified, the bottom line is that the NPE in a 7206 needs to do the job of the RSP _and_ 3 VIPs; no wonder why it will melt. Michel.

See below, I'm mostly talking about no throwing away what you already have; eBay is good for spares (a router sitting in a warehouse does not need software) and line cards, no more. Long-term support: as pointed out recently, I would be more comfortable with a 7500 without support vs. a 7600 with support as of today, the reason being I already know the tricks the 7500 is going to throw at me (mostly). > Drew Weaver wrote: > Well technically buying a used 7500 doesn't entitle you > to run IOS on it, so you need to re-license the Ebay > Special and that usually costs close to what a new 7500 > would cost. True, but I'm not talking about buying a new router on eBay, I'm talking about using what lots of us already have (a bunch of 7500s) that are already paid for and legally licensed. As you unrack some of the 7500s out of production, you take them out of smartnet but don't throw them away: you keep them as spares, which allows you to take the production 7500s out of the 4hour/365 smartnet to put them on support-only maintenance. That's what I call free (it's not exactly, but close): router paid for already and el-cheapo contract on it. > I've heard conflicting reports, is a 7206 faster > at packet switching than a 7507? Greatly depends what's inside it. Sure, if your 7507 has an RSP2 (which basically is a 3640 on a blade) and legacy (meaning, non-dcef) blades a 7206 will beat the crud out of it. However, a loaded 7206 with a low-end NPE can choke when the 7507 with an RSP16 and recent VIPs will sail smoothly. Michel.

I'm not trying to defend the 7500 platform, it's obsolete all right. However, free is music to my ears. Michel.

We found Christopher's request in the "questionable" spool, it was submitted less than 48 hours ago. The EP.NET turn time is listed at 96 hours. The gyrations on the EP.NET end are due to: - office relo - software upgrades (new OS) - spam mitigation processes His request will be processed in the normal window. There are still some issues w/ procmail/spamassasin tuning. --bill

Given that a GEIP in a 7500 can only do 200-300Mbps (packet load dependant), I hope the GSR can do better :) I have heard of instances where enabling inbound packet filtering or shaping on certain GigE cards would cause the cards to shutdown or reboot. I generally don't do shaping/etc on core gear, because its much easier to do it on my aggregation gear (2948G-L3/4908G-L3).

Ours dropped about 70% ... And it's been steady ever since.. we've added a large number of modems since that time as well... Look into 'no cable-arp' as well ... Basically, it prevents arp broadcasts and that also had a major impact on the cpu utilization of our CMTS's..
