LAN on ARC
by Kirti S. Bajwa 18 Sep '03

18 Sep '03

Hi List: I notice that there are 2 LAN on Hiper ARC; eth:1 & eth:2. Do I need to configure both with each with their own ip address? I notice that the documentation only give example of configuring eth:1. Why there are two LAN on ARC? What they are used for (other than configuring)? Thanks.

Filters

I'm trying to get a better handle on the latest viruses by adding some filters to our TC boxes. Basically this is what I've done thus far. I made a filter with the contents: #filter blaster.fil IP: 10 REJECT tcp-dst-port = 135; 20 REJECT tcp-dst-port = 4444; 30 REJECT udp-dst-port = 69; I uploaded it and applied it as an incoming filter on all the modems with "set int slot:1/mod:[1-24] input_filter blaster.fil filter_access on" and "enable ip address_pool_filtering". I turned on the packet logging with "set packet_logging logging all". I've tried various syslog loglevels to see if any of the filtering is working and I don't see any entries related to the filter. Any suggestions or resources I should look at? Thanks! Walt ----------------------------------------------- Walter N.

Clean all!!
by Kirti S. Bajwa 17 Sep '03

Hello List: I am trying to configure 3Com TC for the first time. I have made lots of entries, just experimenting. Now I am ready to configure with correct setting. When I try to configure HiPer ARC, I get error messages saying that these values (mostly IP address) are already used. I have come to a dead end. Is there any way I can clear all the setting on the entire chassis or HiPer ARC cards so I can start fresh? Thanks.

Make sense. Thanks.

Subject: RE: [USR-TC] IP Addresses!!! If you have multiple pools, you can set a priority for which pool will fill up first. Useful if you have two forms of backhaul in that pop and want to use the second backhaul for overflow only. I believe there is also a round robin option to fill incrementally between two ip pools. One of our pops is setup so that the Priority 1 pool goes out T1 backhaul, Priority 2 (180) goes over Fixed Wireless. -- Adam Barnhill -----Original Message----- From: usr-tc-bounces(a)mailman.xmission.com [mailto:usr-tc-bounces@mailman.xmission.com] On Behalf Of Kirti S.

Hi Kirti, To add the IP pool which users get assigned to when they dialup use the "add ip pool POOL_NAME priority 1 INITIAL_POOL_ADDRESS <first ip number> SIZE <number of ips>" command from the terminal interface ( have no idea how to do this in HARM, but if you look in the help for pool you should find it. The local IP address should be the IP address of your arc. Your arc (or both your arcs, if you are using more than 7 Hiper DSP cards) need to have their own IP address which is on the same subnet as your IP pool (it's a routing thing: using a private IP for the NMC is fine, but for the ARC, if you use a private IP, you have to use a private IP pool.) I think you can probably get around this with some routing at your gateway box, but for 1 or 2 IP's, I wouldn't bother. On Tue, 2003-09-16 at 18:44, Kirti S.

RE: LAN on ATC
by Kirti S. Bajwa 17 Sep '03

17 Sep '03

Hi List: 1) While configuring HiPer ARC, do I need to assign and configure both LAN (Ethernet) ports? I have added eth:1 as follows (per documentation): Add ip network <network name> Address <station address/Mask> Interface eth:1 Frame Ethernet_ii As we all know, there is also eth:2. Do I also configure it? 2) When I connect the 3Com Chassis, are the LAN port on ARC connected o the network? If the answer is YES, do I connect both LAN ports? Is there a load balancing between both LAN ports on ARC? Thanks. Kirti

Any body using Quad Digital modems for POTS Dial up?
by Stephen Rivera - WRCA.Net 17 Sep '03

17 Sep '03

I have been told in the past that it was possible to take the Quad DIGITAL modem with quad analog nic to terminate POTS lines. Can anyone here verify that this would work? If so, is there a specific model of the nac that supports this or is it all based on the code load? Any information would be helpful ********************************************************************* Steve Rivera IM: srivera711 (877)WRCANET x102 for more product info got www.wrca.net WRCA , Inc. - 481 Wright Debow Rd.

HiPer ARC upgrade problem
by Mike Cisar 17 Sep '03

17 Sep '03

Was just cleaning up my spare parts rack and decided to flash everything up to the current(ish) firmware versions (using TCM). Everything went just fine with 2 of my 3 spare ARC cards, but the 3rd is being "odd". TCM recognizes the card as an ARC but if I try to do a software upgrade it comes back with an error saying "cannot find SDL file". Does anybody have any ideas/suggestions? Cheers, >>>>> Mike <<<<<

IP Addresses!!!
by Kirti S. Bajwa 17 Sep '03

17 Sep '03

Hello List: I am almost done configuring a 3Com TC Chassis using Total Control Manager as configuring tool. However I am struck at couple of last configuration responses, as below: 1) HiPer ARC: What goes in "Local IP Address" field? Why is this IP addresses needed? Is this IP address same as the IP address in NMC? 2) Where and how an IP addresses assigned to Dial-in users. My understanding was that there is an entry in HiPer ARC, where a pool of IP addresses entered for dial-in assignment. I have no found any such entry. When a dial-in user connects to a HiPer DSP, an IP address is assigned. How and where that IP address is obtained from? Thanks.

You have always given best advice! I was afraid that Total Control Manager program does not have this facility. Thank you.
