Multilink Question
by Joel - Fox Computers 19 Mar '03

19 Mar '03

Is it possible to setup multilink across more than one total control box? Trying to set up a location with 24 PRI's to support multilink ISDN. Anyone provide me any info on doing this? I'm concerned if a call gets split between two different units. Thanks, Joel

Firmware upgrade.
by Justin Wheeler 19 Mar '03

19 Mar '03

I'm attempting to do a firmware upgrade on my systems in the hopes of fixing the consistent problem I'm having with users that just won't go away. I upgraded the code on my DSPs without an issue, and it cleared up tonnes of other issues. When trying to upgrade the firmware, I connect to the chassis using TCM, I tell it to upgrade the .dmf file I have with the newer version of the code, but after it gets to about 90% finished, it stops with "Access Violation" and the ARC remains unavailable for about 20 minutes. I have the 8MB/64MB version, and I'm trying to upgrade from V4.2.32 to V5.0.80 (the latest version I have available, since I don't have a service contract with commworks.) I don't know if I'm running out of space.. list files tells me I have 3783 free sectors, and the file is 3512234 -- I'm assuming a sector is 1024 bytes, which would mean I have 3873792 bytes free, 300k more than I need to flash. Unless, (and I'm not sure if this is fact or not), "min free sectors" means it won't let you write the system down below that amount. Despite all that, the whole reason for my upgrade is the system says, "[psm_open] Endpt mismatch, releasing link" on particular users (specifically, users who're logging in more than once, although, sometimes, it'll let them dupe login 5 accounts, and choke on the 6th, other times, it'll choke on the 2nd. In *all* events, however, it's a duplicate login that does it.) This error comes up when I do a set facility ppp loglevel unsual, show events. Any direction would be great.

Dropping dupe connections.
by Justin Wheeler 19 Mar '03

19 Mar '03

I have my default ppp user set to max channels of 0, 1, 10, and 16. Whenever my users try and log in more than 1 account on the same USR chassis, it hangs up on them after authentication OK is received from radius... The message from debugging is "Endpt mismatch, releasing connection" There are more than enough IPs in the pool for the user, they can log in simultaneously 10 times on my portmasters, so the issue isn't what radius is returning. Any ideas? Regards, Justin Wheeler -- Computer programmer (n): Red-eyed mammal capable of communicating with electronics and inanimate equipment.

What does ENABLE RADIUS RESOURCE_MANAGEMENT command do? What will receive/send radius when this command is enabled? There isn't good explanation of this in documentation/command line reference.

L2TP with encryption
by Yannick MOUX 19 Mar '03

19 Mar '03

Hi, I'm trying to set up a tunnel L2TP with IPSEC between the HARC (LAC) and a router cisco (LNS). At first, I tried set up a tunel l2tp without ipsec. this part is working. Then I tried to add IPsec. On the simulation have the following error on the cisco : CRYPTO-4-RECVD_PKT_NOT_IPSEC: Rec'd packet not an IPSEC packet. I launched the monitor protocol L2TP on the HARC, the tunnel didn't establish. the router did not reply to the L2TP start session request. I didn't know which parameter a forget on the HARC. Is there a command to enable the IPSEC? I created the policy file and actived it, then i applied the policy file to an user. Thanks. Yannick

Re: [USR-TC] Dropped connections

We had the same mysterious problem. It struck at random, and intermittently. We were never able to duplicate it successfully at the office! Anyway, we power-cycled the chassis (actually performing a cold restart), and the problem resolved itself. -- -Tim --------------------------------------------------------------------------- Tim Huffman -----------JORSM Internet, Internet Services Network Ops Manager -----7 Area Codes in Chicagoland timh(a)jorsm.com --------100 Mbps+ Connectivity, 56K-DS3 (219)322-2180 ---------Quality Service, Affordable Prices http://www.jorsm.com -----Serving Gov, Biz, Indivds Since 1995 --------------------------------------------------------------------------- Michelle Mogil said: > > Folks: > > Beginning in March, I've seen a dramatic rise in the number of > complaints among my users. The main gripe is dropped connections: sometimes after 2 minutes, sometimes after 5, but usually before 10 minutes. I have been monitoring the cards and watching connections come and go, but cannot seem to put my finger on any one piece of equipment. The nature of the problem is both random and intermittent: two of my favorite things. Has anyone else had a problem with this?
