(usr-tc) Modem settings?
by Mark Thornton 27 Apr '00

27 Apr '00

I spent the evening changing the carrier loss detect delay setting to 20 as recommended on this list a few days ago, and another question came to mind. What is the proper transmit level setting for quads and hiper modems? The default seems to be 11, but the hiper templates show 12. BTW, what is a template for and when is it used?

(usr-tc) re: resetting bad modems
by Steve Cobb 25 Apr '00

Sorry for calling you Kevin :) What is the best way to reset the modems?? From the TCR or telnet in?? I actually tried a reset modem_groups slot:1 from a Telnet session and it didn't reset the count. I also did a reset from the TCR software (Configure..Actions/Commands...Hardware...Hardware Reset) and that didn't reset the count. Thanks for your help, Kirk and everyone else!

Steve I'm also using Kirk's bad modem perl script and the only way to reset the statistics is to either reset the DSP card or reset the NMC card. The later is usually the best way to do it. In terms of resetting the dodgy modems you can telnet to the DSP card (via the ARC card) issue the "chdev mdm ?" command to get to the modem and then execute "at-d!" to reset the modem pair. This works for most modem lockups. Sometimes you will need to reset the whole card.

(usr-tc) 3Com Office Connect LAN Modem
by Blake Fithen 25 Apr '00

Hello, has any ever done the Cisco equiv. of "ip nat inside source static x.x.x.x y.y.y.y" on the 3Com Office Connect LAN Modem? I have a customer we using trying to use Timbuktu (PCAnywhere type) and it is failing because it's hitting the WAN interface and stopping. (I think). I checked the users guide on 3Com's site but couldn't find anything. many thanks, blake - To unsubscribe to usr-tc, send an email to "majordomo(a)xmission.com" with "unsubscribe usr-tc" in the body of the message.

(usr-tc) resetting bad modems
by Steve Cobb 25 Apr '00

25 Apr '00

I have to TCR at two different POPs. I'm using the Perl script posted by Kevin Mitchell to track modem failure rates. (Thanks alot by the way. It is extremely useful!) Anyway, the busiest TCR has low failure rates on all three DSPs, somewhere in the 0.50% range. On the other TCR, the rates on the two DSPs are very high. Two modems are above 60% on over 300 calls and the rest are all in the 10% to 15% range. What should I do about it?? I tried resetting the modems in TCR but that didn't seem to help.. Also, how do I reset the count in the PErl script?? Do I have to reset the NMC??

(usr-tc) TCR not working
by Steve Cobb 25 Apr '00

25 Apr '00

I just had an entire TCR replace by USR/3COM after some lockup problems. After trying everything 3COM suggested including replacing the HiperARC and the NMC and four days of down time, they finally replaced the entire chassis. Anyway, now I can't access my rack with the TCR software. The Hiper Access software works fine. Any ideas??

RE: (usr-tc) Techie routing discussion :)
by Colin Wantling 25 Apr '00

Jeff, Let's agree to differ. The HiperArc is on my side. Not often I agree with 3COM, will try not to make a habit of it! Regards, Colin Also sprach Colin Wantling >We need Mike to confirm what the mask is on the HARC interface. Again, what the mask is on the Arc interface doesn't...well, shouldn't anyway...matter. Trying to set up a static route, 10.1.1.9/32 with a next-hop of 10.1.1.12, should pretty much *never* give an error like that. Now, depending upon several other factors, it may not actually install the route into the active routing table, but the system should not give the error that it did. In classless routing, there is no problem entering a route such as that above, even if a less specific route that encompasses that route is locally connected, the most specific route is chosen, period. Whether the route is locally connected or static, or OSPF or RIP, or whatever, is not relevant at this point. >His attached network may well be mask /29 /28 ... etc. So? Why should that cause any problem? >This would give the error message he gets as it would then include the >address of the HARC itself. Not a question of Classful/Classless, more >a question of inconsistency and getting caught. But there is absolutely nothing inconsistent about it. 10.1.1.9/32 -> 10.1.1.12 is perfectly consistent assuming 10.1.1.12 is reachable (which the earlier discussion indicated it was), even if its not reachable, it shouldn't generate an error like that, possibly a different error, but certainly not the one that is given. Given classless routing, there is no problem with entering the route that Mike specified. Again...this is purely an issue of 3Com not allowing perfectly legal, though less common configurations. 3Com has decided to protect us from ourselves. The route table setup that Mike would wish to see (and is perfectly legal) would look something like: Network /Mask Next-hop protocol 10.1.1.0 /24 10.1.1.8(eth:0) local (directly connected) 10.1.1.9 /32 10.1.1.12 static (went back and looked in previous messages...the Arc is 10.1.1.8 on a /24 netmask) -- Jeff McAdams Email: jeffm(a)iglou.com Head Network Administrator Voice: (502) 966-3848 IgLou Internet Services (800) 436-4456 - 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) Static Routing Question
by Colin Wantling 25 Apr '00

25 Apr '00

Jeff, We need Mike to confirm what the mask is on the HARC interface. This will get us past this techie discussion an onto helping the guy. His attached network may well be mask /29 /28 ... etc. This would give the error message he gets as it would then include the address of the HARC itself. Not a question of Classful/Classless, more a question of inconsistency and getting caught. Regards, Colin Also sprach Colin Wantling >Maybe yes, maybe no. No "maybe" to it...as long as the next-hop of the route isn't within the route itself, there's no problem. 10.1.1.12 isn't within 10.1.1.9/32, so there's no problem. Even if it were, its *possible* to even get that to work...but there's not a "standard" way of doing it. If you put the /32 in there, its gonna be the most specific route, so it will (should) be referenced before any shorter length match. At that point, the only questions are, "Is the next-hop reachable?" There's another route that is valid for the next-hop address (locally connected), so yes. "Is there a higher precedence route of the same mask length (ie, /32)?" Possible, but unlikely. >The route Mike is adding has a /32 mask, he doesn't say what the mask >is on the HARC ethernet interface already. Doesn't matter. As long as the next-hop for the /32 route is reachable, it should be accepted. Even if the next-hop isn't reachable, the route should probably be accepted...just not entered into the active routing table. >By giving it an address from another subnet, you can beat >the rules. s/rules/bugs/ :) -- Jeff McAdams Email: jeffm(a)iglou.com Head Network Administrator Voice: (502) 966-3848 IgLou Internet Services (800) 436-4456 - To unsubscribe to usr-tc, send an email to "majordomo(a)xmission.com" with "unsubscribe usr-tc" in the body of the message.
