Switching from First Available to Round Robin
by Tim Huffman 29 Jan '03

29 Jan '03

Our Total Controls are currently set up for first available modem routing method (where incoming calls will always hit the first available port), and we are looking at switching to Round Robin (where incoming calls are sent to the next trunk). Does anybody have any advice, experience, or cautions regarding this? -- -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 ---------------------------------------------------------------------------

The only downside I see is that if a modem does go stupid it might take longer to notice. Seth ----- Original Message ----- Seth, You can do Round Robin on the Total Control, your Telco does NOT need to configure anything. RR on the TC Hub just cycles through your MODEMS, it doesn't do anything with the actual channels. Typically the HiperDSP is configured so that Ch 1 = Modem 1, all the way through. So, what you can do is the following: First Available. Lets say 10 people are connected, and modems 1-10 are in use. Then 2 people disconnect (modem 2 & 4), with First Available the next call that comes in will get modem #2 ... and the one after that gets modem #4. Now, with Round Robin. If 10 people are on, 10 modems in use. Channel 2 & 3 become available (user disconnect), next person that dials gets modem 11, and then modem 12 .. Once it cycles to modem 24 (or 23), it goes back to modem 1. And of course, you have your one to one mapping. 10 people connect, modem 2,6,8 disconnect. If Channel 8 gets a call, it uses modem 8, and so on. Therefore, none of these are configured by your Telco. It is all setup on the total control. The Round Robin you are thinking of is controlled by the Telco, where it cycles through ALL available channels, 1-23 -> next span 1-23, etc ... So, then what would be the practicality of it? Well, with some vendors, the modems take a few seconds to reset. Now, if you have a heavy load on your box, that is a problem. Why? Well, if you have 23 lines, and 30 people trying to connect, 7 people will get busy. If that the redialer going, and 1 person disconnects, it is possible that they will get connected while the modem is in a state of flux. Meaning that it has not finished resetting, and therefore can not take a call. Joe user is like ekkk, and complains to you the ISP. You tell him, everything is fine, and he connects then. Now imagine it with a DS3 worth of callers (672) lines, and even more then that trying to connect. You can see where doing a Round Robin, or First Available can be better for you the ISP. It allows the modems proper time to reset, and therefore stop the half ass connections. I have seen this a LOT with Ascend (Sorry Ascend people), not really with TC-Hubs as much. But, I am sure that it can happen. Well, I hope that helps out some. Enjoy, Brian Smith CCNA, NCSA Network Support Engineer SOLUSERVE www.solunet.com 1571 Robert J.

I've found that when they misbehave a stun gun usually helps.

NMC Hub Status
by Stephen Amadei 28 Jan '03

28 Jan '03

Gah! I've got 6 chassis' with dual ARCs, and HiperNMCs, 14 DSPs in one location. All the latest TCS4.5 code. However, one of the chassis's is giving me a red "hub status" on the NMC. The chassis runs fine, otherwise. I've tried swapping out the NMC, rebooting, firmware upgrades, etc... it stays red. Actually, it goes red a few seconds after the NMC gives a console on the RS232 port. This is a _real_ basic question. How do I find out what is causing this? I've looked in the TCM and I'm pulling my hair out, as I am stumped. Any thoughts? ----Steve Stephen Amadei Dandy.NET! CTO Atlantic City, NJ

More questions...
by Stephen Amadei 28 Jan '03

28 Jan '03

I have two more questions that came up tonight during a reconfig. 1. I have implemented a new way of doing my ip pools... using the priority feature. I have four pools with priorities of 10, 20, 30, and 40. However, the total control is still giving out addresses round-robin from the four pools. What is wrong? 2. I have been doing some experimentation with the eth:2 port. I gave it an IP address and put it into another router, added a second default route, and it works... disconnect one cable and the other continues working... but only on one chassis. The second chassis doesn't... you can still get to the ARC, but not the users. I use RIPv2 to route to get from the main routers to the users... and the RIPv2 entries look the same. Any ideas? 2b. Adding the second eth port, my RADIUS and logging started getting the wrong IP address... I had the same problem when I had two IPs on one interface... I see an application_source_address feature, but by specifing this, won't I be breaking the redundancy I'm trying to set up? Are there better ways to do this redundancy? Thanx, guys. ----Steve Stephen Amadei Dandy.NET! CTO Atlantic City, NJ
