I am observing fail calls(badmodems.pl) for DSPs( e1/r2 lines) performance monitoring. Now I want to reset that calls statistics counters for one DSP only, and want to observe from 1 now. How do I do counter reset for that dsp only ??? I gone through TCS docs online ,but unable to find any proper command What do I need to configure for telnet to DSP??? I want more documentation abt T1, E1, E1/R2 ...settings etc Thanks pankaj

Multiple ARC's
by Joel - Fox Computers 19 Aug '02

19 Aug '02

Having a small problem - wondering if anyone has any suggestions. What I want to do is change out my ARC without disconnecting users. The main purpose is to upgrade the code on my live ARC; however, once it's upgraded, I thought I might leave both ARC's in the chassis just for the sake of having more blinking lights (Sorry, I just like blinkin' lights). Here's how my chassis is config'd: Slot 1: Hiper DSP Slot 3: Hiper DSP Slot 15 (front): Hiper ARC Slot 15 & 16 (rear): Hiper ARC NIC The Hiper ARC in slot 15 is configured as follows: NMC SETTINGS Chassis Awareness: ENABLED Dynamic Slot Assignment: DISABLED DSA Idle Rebalancing: ENABLED SNMP Forwarding: ENABLED My plan is to get a new ARC in slot 16 and get the one in slot 15 out, or at least offline so that it can be upgraded. Here's what I tried to do (that didn't work): On the new card, using a backup/offline chassis, I configured it as "slot 1-16 owner no", and disabled nmc chassis awareness. Also disabled chassis awareness on the "live" ARC in the online chassis. I thought I could put the new ARC in slot 16, then "soft busy out" the DSP in slot 3. Once there were no more open sessions on Slot 3, then I would give the old ARC a "set chassis slot 3 owner no" and the new ARC "set chassis slot 3 owner yes". Then, in a perfect world, restoring the DSP in slot 3 and busying-out slot 1, new connections would go to slot 3 and the new ARC. Then doing the same again once there were no new connections on the slot 1 DSP. Didn't happen - when I do this, after changing the ownership on the ARC's, the slot 3 DSP won't take calls. I'm sure it's because the new ARC in slot 16 doesn't recognize the DSP in slot 3. A "List chassis" shows all the slots as "--EMPTY--". Is there a better way to do this, or do I have to specifically tell the ARC in slot 16 what type of cards are in the DSP slots? Ideas? Recommendations? Thanks, Joel

Maybe you have a bad cable or a bad card - have you tried to hyperterm to the ARC as well? If you can communicate with the ARC and not the NMC, maybe it's a bad NMC. If you can't connect to the ARC either - then it's gotta be the cable or the com port on your PC or a software problem with windows - so then try using a different PC. Are you using a laptop? A LOT of laptops, particularly Gateway's, have flaky serial ports. -----Original Message----- From: Jason [mailto:jmiller@tablerock.net] Sent: Sunday, August 18, 2002 12:18 PM To: usr-tc(a)mailman.xmission.com Subject: Re: [USR-TC] Initial Setup Yes tried that with no luck.

RE: [USR-TC] What is a conservative dsp to arc ratio?
by Joel - Fox Computers 16 Aug '02

16 Aug '02

Just for information - I've run a HiperARC, 2 DSP's, and an NMC on a single 35A Supply without any problem. Assuming all cards use approx. the same power, 15-16 cards should run on 140A of Power. I would guess that you rarely need more than 130A, having two is for fail-over protection. Just a guess, I'm no expert. - Joel -----Original Message----- From: Chris A.

At how many ARCs and DSPs would we need to switch to 130A power supplies? Would having two 70A supplies serve the same purpose as having one 130A, other than the obvious fact that if one of them were to go down, the chassis would be very underpowered. :) Thanks!

Re: MRTG
by Ralph Forsythe 14 Aug '02

Ok, something isn't right here. I can't use the HiPerARC MIB info as it's completely different, however I found something which reads the NETserver - or does it? This is what I have in the config: # TotalControl Connected Users in Netserver Card (using Quad modens and dual pri) # Target[TCNetserver]: 1.3.6.1.2.1.2.1.0&1.3.6.1.2.1.2.1.0:<comm>@x.x.x.x - 1 # MaxBytes is number of modems. Will go by total in cards, so 2 would mean 4, 4 = 4, etc. # Set to 8 for 2 ana cards. MaxBytes[TCNetserver]: 8 Title[TCNetserver]: Connected Users - PPP-CHAS-DEN-01 ShortLegend[TCNetserver]: Users Unscaled[TCNetserver]: ymwd YLegend[TCNetserver]: Users Legend1[TCNetserver]: Users Legend2[TCNetserver]: Users Legend3[TCNetserver]: Users Legend4[TCNetserver]: Users LegendI[TCNetserver]:  Digital Connections  LegendO[TCNetserver]:  Analog Connections  Options[TCNetserver]: gauge PageTop[TCNetserver]: <font face="Verdana"> <H2>Number of Connected Users - PPP-CHAS-DEN-01</H2> What's happening is it counts the sitting login at port 0 (console port), hence the -1 at the end of the IP. However, I have tried logging in with both local usernames and RADIUS auth, and it never counts these users. I'm sure I just have something screwy here - it's reading the basic SNMP from the card ok so I know that's right, it just doesn't seem to be able to count ports for some reason. I don't know if this is because it's trying to count cards in the T1 interface or not - I am using 2 quad analog cards at the moment, as I don't have enough volume yet to justify a T1. However the MRTG screen has to plotted values, one for digital connections and one for analog, so I would think it knows what's going on. Help, please! Thanks, - Ralph

MRTG
by Ralph Forsythe 14 Aug '02

14 Aug '02

Ok, does anyone have a brief explanation, or example of a config, for using MRTG with a Netserver / Total Control? I would like to monitor the number of modems in use out of the total active ports (which could change from time to time - re-making the config is ok there if I need to), and possibly the total bandwidth usage - either per port, total, or both. I tried following the example found at the link below, but just got a lot of MRTG errors after playing with various options, and figured someone might just be able to post a snippet of their config file. http://www.dcr.net/~mandrews/usrtoys/mrtg.shtml I know a tremendous amount of information can be gathered frrom SNMP on these things, I just don't know much about how to do it... Thanks, -rf
