XakEp posted:As I understand it, thats what its supposed to do. Pick best path routing and route the traffic over the links that'll get the data there faster. As one route gets congested, it switches over. Yeah but shouldn't it be a soft cutover, where current traffic on that line keeps flowing? I'm getting the impression that it's just doing a hopping dance between the two lines, completely moving everything over at the slightest hint of congestion, instead of balancing load across both links simultaneously.

M@ posted:They're certainly trying like hell to stomp out the used market. They like painting the "grey" market as stolen/counterfeit gear and don't have any problem telling customers that. Part of that reasoning is that they can't have any real knowledge of the chain of ownership on any given part, and stuff like T1 WIC cards are easily counterfeited. I've had at least 3 couterfeit WICs pass my desk in the past 3 months, and two of them went bad within 30 days. If Cisco had to support that, it would be a monetary black hole.

Is it possible to break out individual serial T1s (for MLPPP, bonded t1) from a ATM-IMA card? I've got this card in one of our 7206VXR routers, and want to run a MLPPP connection for lab/testing purposes, and I can't seem to find any configuration notes on google. We were originally using this card for a 8x T1 IMA interface, but have since upgraded that connection to a DS3. Now that this card is vacant I want to putz around with configuring it a little. IMA WAN DS1 Port adapter, 8 ports PA-IMA-T1

inignot posted:Eh? MLPPP and ATM-IMA are two totally different types of link bonding. I really doubt you're going to get anywhere with this. Actually, without a spare ATM switch I don't think you're going to be able to do anything with the IMA card. That's why I'm asking. MLPPP is a software implementation on top of whatever interfaces you put into the bundle, right? So if I could break out individual Serial T1's instead of using the IMA bundle, couldn't I do MLPPP? Basically I have that IMA card with 8 ports in my lab, and I've got a 2611 with two WIC-T1s in it. I was wondering what it would take to connect the two together.

inignot posted:Ok, here's the short way to test this. Try to use "encap ppp" on one of your IMA interfaces. Well yeah, that doesn't work since it's still an ATM/IMA interface. I was wondering if there was some way to configure one of the ports as a serial T1 like you can with the VWIC-2MFT-T1 cards. At this point I might just dig around and see if I can find a spare ethernet PA card & ethernet WIC to test with. Thanks though.

just a short follow up to this:jwh posted:What serial console software do you use? I have an older G4 PowerBook that I wouldn't mind carrying around instead of my heavier Dell. The big obstacle that I ran into is that there aren't a lot of serial adapters out there that have updated drivers for intel macs. As far as I know, Keyspan offers (every)mac compatible devices, and generic ones based on FTDI chips will work if you download the FTDI driver from the chipmaker's site. http://www.ftdichip.com/FTDrivers.htm

Are you doing any NAT with your firewall? If so there should also be a "static" rule somewhere in there that you need to check, incase you're only doing port forwarding instead of one-to-one static nats.

The last two slots are marked for voice only, but I wasn't quite sure if I could use the second slot for the remaining VIC. What're the requirements for using the voice features on a card? Could I just toss a VWIC-2MFT-T1 in an 1841 router and use one of the channels as a PRI? jbiel posted:While that is a viable option, why not keep the loving MAC tied to the port as long as the port stays UP/UP? God drat Cisco. well what happens if you have some device on the other end like a smartjack that just keeps the interface up? What about hubs on the port?

The initial statement was an answer to your question: "Can you use a VIC-2FXO in any slot" and from that page I found it seems the answer is "yes." The second half is a question. I'm really tempted to see if I can do some VOIP routing with cisco products. (I want to see if it's better/smoother/cheaper than VOIP over Adtran... which is pretty drat easy.) So I'm wondering what I would need in order to get started screwing around with Cisco voice features. Any VIC/VWIC and a router with a IP PLUS load...? Yes? No? is there more to it? Any good tutorial sites or white papers on people doing this? Oh, and as for the poster looking at OER earlier I might suggest a "pass" on it unless you've got plenty of CPU free on your router, as OER seems to work best if you're preforming NAT on the OER border routers because otherwise your return paths won't match the outbound interface.

I think part of it is our sales guy, who at this point has stopped returning my calls. From what I can see, all the fiber vendors are dragging their feet with fiber installs because it tends to require significantly higher human investment in the install process. A lot of their older tech like coax DS3s are faster to roll out because half the work is already done. My company's fiber rollouts are at the mercy of SBC, and that can be like pulling teeth some times. CrazyLittle fucked around with this message at 07:58 on Feb 27, 2008 |

Ahhhhh I just have to say this:  Success!!! OER works! It's pretty cool having two DSL connections and a T1 all work in tandem, but there are some definite drawbacks. Some session based sites get confused by the multiple routes that OER can assign. The configuration is a real pain in the rear end. ahh gently caress it I'm tired.

You can telnet direct-to-port and I don't think there's any real authentication on that feature. Beyond that though you can wire one up to be in/out on any port with or without modems, and even SSH/telnet out from the device. It's really flexible.

Girdle Wax posted:I wouldn't recommend it, is the equipment on both sides 'trusted'? You could run something like EIGRP between the nodes and do unequal-cost-multipath and let CEF load balance for you. With OER and other load balancing options that only load balances for the egress connection and the return path is not really accounted for. That doesn't work for customers of ours who run small employee internet-visible portals or VPN servers. So why do you "not recommend" using MLPPP to form a big pipe out of dissimilar interfaces? We already do a lot of multiple-T1 bonding with MLPPP. It just doesn't make sense to have 4xT1 circuits just so that two people can VPN in while the office gets a 6mb download speed. (oh, and just for fun my office moved, and I setup a bonded ADSL pair connection because we could only get 3mb/768k) CrazyLittle fucked around with this message at 01:51 on Apr 9, 2008 |

Ahh that makes sense. I'd guess that the router would freak out, error out, or just lock the connection until things arrived in order, and all three of those scenarios are equally bad. I'll stick to bundling same interfaces, but it would be nice if I could find some simple ingress load-balancing.
