(usr-tc) Dead TC unit - Update 2 - HELP!
by Brian Elfert 08 Dec '99

08 Dec '99

I've been playing with a dead TC unit for hours now, and I still can't get it working. It has 45A chassis, quad modems, PRI NAC with T1 software, and a Netserver card. At present, it appears to only answer on a channel or two. The rest of the channels get dead air. The telco is reporting not getting a wink back when they test it. (This T1 works fine with other units) I've tried: 1. Setting all modems to default, and resetting them all. 2. Moving all cards from this unit to a spare 45A chassis. 3. Copying config of PRI NAC and quad modems from a working chassis. 4. Removed all but one modem card. Seemed to answer calls fine with one modem card during two hours of bombarding it with calls. 5. Power cycled a dozen times. 6. Set all modems to inactive in Netserver and reactivated them. Any other ideas? I have 6 more quad modem cards I can pull from a working unit, but I don't want to end up frying them somehow. I also have a 186 T1 card I could try swapping in, but I think it has old software, and it may not work with the rest of the software revs. Would swapping out the Netserver card and NMC card possibly help?

(usr-tc) Telnet lock out?
by farber＠admin.f-tech.net 08 Dec '99

08 Dec '99

Hello all I'm writing a perl script to log into an ARC and get some info.... but it seems that after so many invalid login attemps you get locked out (i believe the RFC says 10 minutes?). Can I turn that off? I do have the ip listed in telnet client's table.

(usr-tc) Software Download for MP16
by Dave Martin 08 Dec '99

08 Dec '99

I need to reflash some modems on an MP16 that have somehow gotten themselves stuck waiting for software download and cannot for the life of me find the software on the 3com web site. I found the mpv90an.zip file that contains the MP12_02.exe downloader but would rather use TCM to perform the download since the MP is about 1.5 hours away. Can anyone point the way?

(usr-tc) anti-spoofing, per user
by Jesse Sipprell 08 Dec '99

08 Dec '99

Until recently I had been using: enable ip SOURCE_ADDRESS_FILTER set network user default PPP_SOURCE_IP_FILTER enabled to prevent network users from spoofing source addresses. I now have one customer who has the need to have multiple subnets routed to them, which requires me to turn this option off globally. Is there any method of leaving this ON, but turning off PPP_SOURCE_IP_FILTER for a specific user via RADIUS?

(usr-tc) X2 Key still necessary
by Ralph Helfenberger 08 Dec '99

08 Dec '99

Hi everybody I would like to upgrade a Netserver/Quadmodem based Chasis to V.90. When I did this last year I had to buy a X2 enable key. This product is no longer available. So the question I have: Is this key still necessary? Or do I just upgrade the Quadmodems to the latest code and then I have V.90 automatically enabled?

(usr-tc) [SUMMARY] slow MLPPP on HiPerARC
by ROC Services 08 Dec '99

08 Dec '99

After a little correspondence in private with a helpful and clueful 3Com employee (thank you), we've figured out the cause of the slow MLPPP we have been seeing with the HARC. It seems that the HARC does not fragment packets for MLPPP, it simply round-robins them out the interfaces. While this doesn't cause performance problems with sane protocols such as TCP, the software that our customer is using attempts to reinvent TCP over UDP. Badly. It sends one big packet, then waits for an ACK before sending the next one. The net result of this is that on a simple "ping" style test, a multilink bundle of any number of links won't show a significantly lower roundtrip time than a single link would. Also, I mentioned "mon ppp" showing traffic over only one interface on a multilink connection. This was confirmed as a "mon ppp" issue by 3Com. The "TAP USER" function shows traffic distributed across all interfaces. The "mon ppp" problem is slated to be fixed in upcoming releases, and there are plans to add a configurable parameter and/or RADIUS VSA to cause the HARC to fragment outgoing packets on multilink. As a temporary workaround until this code is available, we've found that lowering the link MTU for this particular customer alleviates the problem. It should be noted, however, that lowering MTUs may cause problems accessing certain sites that block all incoming ICMP. - To unsubscribe to usr-tc, send an email to "majordomo(a)xmission.com" with "unsubscribe usr-tc" in the body of the message.

Re: (usr-tc) X2 Key still necessary
by Todd Keister 07 Dec '99

The X2 key is a Feature Enable that is entered in to your NMC card on Quad chassis only. DSP cards come with V.90 enabled already. It is only an issue for Quad chassis and the presence of a NETServer, Hiper Arc, or Edgeserver Pro is completely not relevant. The only time trouble arises is if/when the X2 key gets lost or corrupted on the NMC. The the X2 key (just an alphanumeric string) then must be re-entered. Most frequently we see this when someone has an NMC that goes south (electrical storms anyone???) and then the key must be re-entered on the new NMC card. We have files listing all registered X2 key holders, but this particular database is much easier to access if we have proof of ownership. So if anyone has a problem with a lost X2 key, just call us at Tech Support. We are here to help. Tech Support: (800) 231-8770. Hope this helps to clarify this issue and answer everyones questions.

Re: (usr-tc) X2 Key still necessary

Flashing new code to an NMC will not remove previously installed feature enable keys. Code for the various cards is tested and released in matched 'systems releases', the latest being TCS3.5. I know of no reason why you should not run the code from this release. Someone else with more operational experience might be able to tell you specific quirks that they may have found. You may find some unusual behavior if you mix codes from different releases within the same chassis. The Software Compatibility Matrix is posted on http://totalservice.3com.com and documents what codes are included in each release. TCS3.5 includes NMC 6.0.9/6.1.17/6.2.17, and Quad 6.0.6/6.1.6.

If I am installing a v90 NMC to a chassis that had not been running v90 standard, Is the card all I need to install. Some people have mentioned that you have to match the code on the modems. Is that true? Can anyone suggest a stable, v90 compatible sequence for the modems (Quad Digitals) and the NMC v90?

You need only add the X2 key to a chassis once. Any quad modem code upgrdes after that will then use the same key.
