RE: [USR-TC] Channelized T1 in a DSP

I'm using CT1's with DSP's - copy and paste me your Trunk Settings and I'll try to help. - Joel -----Original Message----- From: WayneG [mailto:WayneG@uplogon.com] Sent: Tuesday, November 26, 2002 9:32 PM To: usr-tc(a)mailman.xmission.com Subject: [USR-TC] Channelized T1 in a DSP Anyone using a Channelized T1 into a DSP? We have a TC boxes with PRI's into the DSP's running no problem. But in this location we are using a T1 (no PRI tarriff) and cannot get the TC to accept a call. It rings, 3 seconds of silence and then busy. I have swapped complete chassis and all cards, and reset everything to defaults and reconfigured. I have a feeling that there is some setting in the ARC that I am missing that is different between a T1 and a PRI (like modem mapping or something??) I changed the DSP card from "Message Oriented" to "Bit Robbed." But everything else is the same as our PRI chassis. Help???

MPIP + OSPF Hell
by Joshua Coombs 26 Nov '02

26 Nov '02

I currently administer a pool of 8 TC1000 chassis, and have been pulling hair out trying to stabilize OSPF. What we are seeing is some TC's refuse to ack some LSA reannouncements from the DR, causing it to eventually drop and restart OSPF sessions at random times. Every now and then this 'corrective' action taken by the DR will trip up a batch of TC's and 5 or 6 will all drop OSPF and reload their sessions. These hiccups are quite noticable to our dual channel ISDN customers (whom also seem to trigger the activity.) Our setup is as follows: 8 TC ARCs, all in the same ospf area (not the backbone) with one addition ospf neighbor, a Cisco router that acts as the DR and ABR to the backbone area. TC7 is the mpip server for the group, all chassis are clients with eachother. Dual channel callers are just as likely to land across chassis as they are to land with both links on one chassis. All callers get subnet/route info, if any (99% just use a single link, and get an ip from the dynamic pool) from ppp, we do not do any routing exchange (OSPF, RIP, BGP, etc) with any customers via dialup. This problem manifested when we turned up ISDN on this network. Before there were no multi-link customers dialing in, and the setup was fairly stable. Since turning up MPIP however, we have multiple ospf session failures a day and our customers are getting quite annoyed with the pauses or unusable connections they cause. Can anyone point me to a good walkthrough on a 'proper' MPIP setup so I can verify that I'm in compliance there, and does anyone have any other suggestions on how to fix this mess? We're currently running 4.5 Joshua Coombs

Filters - me no understand
by Scott M. Trautman 26 Nov '02

26 Nov '02

Hi-- Well, it seems every so often that my filters no longer work - as in not being applied. Now is one of those times, and I'd like to understand what is going on. Looking at an interface, of a logged-in user, I see: INTERFACE slot:10/mod:16 SETTINGS Description: GWC Modem Driver Type: RS232 Speed: 28800 High Speed: 0 Administrative Status: Up Operational Status: Up Link Up/Down Traps: DISABLED Promiscuous Mode: FALSE Connector Present: TRUE Filter Access: ON Last Change: 18d 23:41:04 Policy Access: Private Policy File: Input Filter: Output Filter: Host Type: SELECT Connection Type: NORMAL Port Type: LOGIN_NETWORK User Name: Access: TWO_WAY Cojent being the "Filter Access: ON" And Input Filter: Output Filter: Even though this user has, as applied upon login from RADIUS: Framed-Filter-Id = adult And I do have the filters on there: list filter: adult.in NORMAL IP adult.out NORMAL IP Okay-- Why then, does it not appear to have applied a filter? I'm using: System Version: V5.3.3/Non-Encr ...but this craziness seems to happen regardless of version. I used 'set modem_groups all filter_access on' to begin with, and that doesn't seem to be an issue. I've got to be missing something here - can anyone help?? SMT

wierd snmp traps
by Trevor 26 Nov '02

26 Nov '02

I'm having a problem with unknown traps being sent to the trap handler. The bossman wants us to be alerted when there are problems with circuits yellow/red alarms/ds0's out of service etc, which those all work, except I keep getting "common" traps sent to the handler. I've searched and searched and can not find the mib files for these. I've shut every trap off that I can find, with the exception of the ones we need. I am still getting these. I've gone through every usr mib I could find for the past 4-5 TCS revisions and still can not find anything that can ID these. common.34.3-6.1 common.2.2-6.1 common.2.2.0-6.1 If anyone can help point me to where I could get the mibs for these, it would be much appreciated. Thanks! -Trevor
