I had the same issue with FRF.12. Sounds good in theory and on papaer, but in the real world, it never works. FRF 11 Annex C is OK (VoFR) and PPP multilinking is OK, but FRF.12 is no good.

Re: To IP telephony experts: Who's the best? [7:28714]
Price wise, depends on the size of the job. For a small company, Cisco is WAY too expensive when you compare an AVVID solution to a small PBX. For good price for a small company go with a 3COM NBX. But with the 7750 being re-released, the 7750 may be getting more cost competative. I think it's going to be released for 12K, but that's an empty system (no WAN ports, switches, etc.) and those add up fast. It's too hard to justify a 225% increase in price just to say you have a VoIP system. Once you get into Unity and unified messaging, the price skyrockets. Once you get to a big job (1000's of users) the AVVID solution quickly surpasses the big PBX's in terms of cost. Performance wise, Cisco is the most flexable in terms of scalability, and options. Nortel is the worst. Their BCM they have is a pice of junk. I have limited info on Alcatel's stuff, and Lucent's (if they're even still in the enterprise market as we speak).

Re: 2 priority queues [7:28227]
You are correct that it creates only 1 PQ. As for the second point, you bring up a good scenario where the PQ gets filled up and the rest of the high priority traffic gets dropped. I never thought about it before, and I guess it just falls into a design category. Either plan for worst case scenario and always guarantee there will be enough bandwidth for that high priority traffic or maybe RSVP or H.323 Gatekeeper may be a better option, as either will "ask" is bandwidth is avail, and if not, (in the case of voice) send it off net to the PSTN.

Re: 2 priority queues [7:28227]
I like to learn, so forgive me if I am beating this subject, but in order for me to become a CCIE, I need to know everything. I've been reading up on the real story on two priority queues, been asking a couple of CCIE's and been on CCO. Just as I suspected, there is only 1 PQ in LLQ, or any queuing method for that matter. If you enter two (or more) different classes to have strict priority, the all enter the same priority queue. To quote from Cisco: "...The Low Latency Queueing feature provides strict priority queueing for CBWFQ, reducing jitter in voice conversations. Configured by the priority command, Low Latency Queueing enables use of a single, strict priority queue within CBWFQ at the class level, allowing you to direct traffic belonging to a class to the CBWFQ strict priority queue. To enqueue class traffic to the strict priority queue, you configure the priority command for the class after you specify the named class within a policy map. (Classes to which the priority command is applied are considered priority classes.) Within a policy map, you can give one or more classes priority status. When multiple classes within a single policy map are configured as priority classes, all traffic from these classes is enqueued to the same, single, strict priority queue" Here is the link for surther study. http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120 t/120t7/pqcbwfq.htm I am still researching Mike's claim that states that fast-switching bypasses the counters for the queue.

Re: Cisco CallManager (CM) Redundancy [7:28043]
Not a valid setup at all. Centralized CallManagers can't fall over to a remote CallManager. In fact, a remote CM can't even be clustered over the WAN (unless it's faster than 10MB link). For remote site fail over, you need SRST off of a router to PSTN. It's a temp solution until you get the WAN link or CallManager back up. For PSTN fallback in CallManager you need to create 2 route lists in CM. First choice would be WAN. 2nd choice would be PSTN. Add both to a route group. wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Dear All, > > Need some advice on the redundancy features of CallManager.

Re: CBAC question [7:27751]
Remember this rule: For CBAC to work (let something back in), it has to have an access-list bocking it. Let me explain. CBAC is a tool the monitors communications over an interface and protects against session hijacking, and other hacking exploits. It's also a tool thet lets something pass through only if it started on the other side. So if you have a client inside that initiates a web page download, (port 80), CBAC will only let the page back in if it flow was initiated from iside the network first. It's a glorified access-list with the "established" keyword. You put CBAC on in interface in THE DIRECTON YOU WISH TO START THE COMMUNICATION. This starts the monitoring session of that flow. Then in order for the packet to come back in via CBAC, it needs an access list to first stop it. Here's a correct implementation of CBAC. Notice that access-list 100 blocks everything in the world but ping replies from comming back in. Without CBAC, nothing would come back in, but with CBAC on, if the communication started on the inside, the comminication will come back in. This is why you need an extended access-list for the external interface, because what if you just wanted to monitor POP3 mail sessions, you would need an extended list that can block 110. A standard list will not block 110.

Re: ISDN Q.921 and Q.931 [7:27568]
I was wrong. I looked it up last night and there is a seq. number in the control field of LAPB, HDLC, and LABD. Both, the sending and receiving stations must keep the same seq. numbers when transmitting, but I cannot find anything on retransmission at that layer. But I asked an old IBM guy I used to work with and he said that SDLC and all the related layer two protocols do require retrans when bad packets are found or missing. So I would assume that LAPD layer two is reliable. And as everyone else said, the SS7 signalling (Q.931) is just control and status messages over D channel. And B channel is a different retrans technique, based upon the higher layer protocols it carries. If an ISDN frame gets corrupt, both channels will be retransmitted, but by differnt methods. So ISDN D channel is inherently reliable at layer two and B channel is reliable only if that higher layer protocol is.

Re: ISDN Q.921 and Q.931 [7:27568]
q.921 is D channel, but is like a layer two protocol in that it just cares about addressing on the wire beteen the equip and the swich. q.931 is only run on D channel. Q.931 is part of Q.SIG, the telecom standard signalling. This is LAPD. If an ISDN packet is lost in the end-user context, corrupted, or whatever, I would think a higher level protocol would request retans if it was reliable (TCP) and not ISDN. Theres not even a seq number in q.931, so I would't think it would know it was missing a frame.

To be honest, it just sucks right now economy wise. No big deal. The business world is, as we all know, cyclical, and it will eventually come back up. We didn't slide into this overnight, and we won't come out overnight either. Now is the time to study, get certs, go back to school and prop yourself up for the next boom. Everyone is hurting, even Cisco themselves. People are still getting laid off there as we speak. As for the CCIE's wishing they never did it, well they need a reality check. Of course the market will be diluted with CCIE eventually, but it's not yet. And they need to ask themselves, are they better of with their CCIE then without? Of course they are.

Re: Which path to take? [7:26918]
I'd say over the long run, both are lucrative aspects of networking, but I feel that VoIP may be a better choice. First off, Cisco has staked it's future growth on the next-gen converged networks of voice, video, etc. The plain old data market is not completely saturated, but it's getting there. If voice dosen't work out, they wont be able to grow as rapidly as they have in the past (unless optical takes off again). So what's good for the goose is surely good for the gander. Voice has a huge growth potential, and there are numerous studies showing the market growing by leaps and bounds over the next 3 -5 years. I'm not saying that plain data isn't a big business, cause it is, but it's not growing by leaps and bounds like it used to. Secondly, with voice such a new skill, the playing field is completely leveled, even against most CCIE's. I attend many classes at Cisco, and hang there in the labs once a week, and I've seen plenty of SE's and CCIE's just clueless (even TAC) about voice. And even if they're not clueless, they have been studying just as long as everyone else. So in terms of skills, you have a shot to be one of the leading people. The number of CCIE's is getting bigger all the time, and there will be a point where they aren't as valuable. Face it, when they were super-valuable, it was because networking was such an in demand skill, just as voice will be. It's all supply and demand. I'm not saying CCIE's aren't still valuable, but their worth is declining. (On a side note, new technologies are pretty cool, and you get to meet the cream of the crop working on it. I got to meet Wendel Odom last week and had the distinct pleasure of having him give a lecture on QOS (important skill in new networks)! Where else could you meet such distinguished people? Certainly not in a ICND class or even a CCIE bootccamp). Also, last week at Cisco in MA, there was a pretty big showcase to all the local business big wigs about the future of VoIP and AVVID, so the buzz is out there and businesses are noticing. Our sales people are swamped with VoIP related stuff. One guy told me on of his contacts who own's a business was golfing with a buddy when they began talking about VoIP. The business guy didn't even know what VoIP was or what it did, but he had to have it he was saying. I feel that converged data networks are the future, and will be a ubiquitous as e-mail is today. Security is good also, but it's hard to educate people that they need a secure network, so it's harder to get a sale in for that stuff.

Re: Tcp window size question [7:26861]
You are correct in that the tcp window size sets the freq. of acks. The receiver decides the window size based on a "credit system" based on how well it received your packets in the past. Unfortunately, it's an unfair system since you have no control of how the packets do across the network, especially in the harsh world of WRED, Frame Relay switch DE's, and other outside influences. As for why you are getting on ack every two packets without it ever increasing is beyond me. It should go 2, 4, 8, 16, etc..

Re: Frame Relay question. [7:26819]
The wan provider maps the DLCI to the IP of the FR switch at the opposite end through special tables.. Furthermore, the Frame Relay header is stipped off when entering the cloud and travels around via regualr IP or ATM, etc. The FR header is then put back on once it reached the opposite FR switch. They police your speed with CAR.

Also depends what you are doing on router. If you are running at 50% now, and want to do CBAC and VPN, then don't use that router.

Re: CBWFQ (Class-Based Weighted Fair Queing) Question [7:26197]
TO sum it up, it guarantees and limits bandwidth. The PQ gets services over all the other queues (proably voice traffic) and then the CBQ gets serviced according to the bandwidth you configure for each class. So when you config the bandwidth you could consider is guaranteing what you put down or reserved. It's all semantics. The rest if WFQ'd and is a free for all in that queue, especially if the traffic is not classified, it essentialy becomes round robin in that queue.

Re: Private phone numbering [7:26021]
It can. At home it definitly does. Once you get a PBX or KSU, you havemore control over the exstensions. If you order one number for the main site and you have extensions that you have to dial to get to the individual phones from the automated attendant, then you can make those extensions what ever you want. And if you have DID, the Telco may give you a block of numbers, say 1000-1099, you can either use thos as your extension such as (nnn) nnn-1000 or you can map those into your internal extensions. So a customer outside may call you at (nnn) nnn-1000, but your internal co-workers can get to you by dialing your extension number which may be x3546. You would map the DID number to the extension on the PBX, like you do in NAT.

Re: Private phone numbering [7:26021]
DID is the "public address" of voice, but you may still need to map over DID numbers to your internal extensions. Otherwise you need an auto-attendant that asks you to enter the extension of the person you are trying to reach, which could be considered the NAT of voice, since you need a box to route your call to the proper person.

Re: Dial Plans [7:26027]
Depends on who is doing the routing. A PBX is capable of doing all it's own dial-plans, or you can give the call-routing decision making to a cisco router and have it do it, which also makes it way more configurable. You really don't even need a router to tie two PBX's together if you want, just use E&M and some Adtrans. The Intergrating Voice and Data networks by Cisco Press gives a pretty comprehensive run down on the pro's and cons of router handling dial plans vs PBX doing dial plans..

Re: CAT 5 cables - off topic [7:26081]
This is the forum for asking wiring questions. Any CCIE worth his/her salt will know the physical layer of networking. Now for your question, that will be fine for 10/100. But don't skimp out on price and just get the 1,2,3,6 wires. I'd get all 8 pairs in the wiring because GigE uses all the pairs, and it's almost nothing in price difference once you are paying someone to do the wiring. Labor is always the most expensive. Plus it may be Cat 6 compatable when it gets standardized in a few months. Also, IP phones getting their power from a power-patch panel need the other pairs for power, if you ever go VoIP Cisco style.

Re: CID: Tie Trunk [7:25886]
A straight T1 clear channel line can get expensive depending on the distance, plus that makes it an OPX (off premise exteansion) line. You should use E&M for the tie line between two routers, then some sort of WAN circuit to bring the two together. You can do anything such as FXS to FXO, etc,. but the proper voice way to do it is E&M. You could do PRI (voice pri, not ISDN) to carry the digits to the other PBX, clear channel, VoIP, VoFR (then you bring in a router of some sort to CODEC and encap the voice). Basically you need a pyhsical pipe to carry the voice between two I work for a voice company right now, so I am getting all the info right from the voice guys. (Also, I can't seem to escape these Cisco Press authors. One of my instructors at my QoS class at Cisco is Wendel Odom.)

You can use E&M cards in the PBX's and in the router and use dial-peers, etc. That's the best solution. just be sure thay have a good dial-plan to support it.

Re: Etherchannel between 5509 and Intel Pro/100 NIC [7:25746]
PAgP for EtherChannel is for two Cisco devices that can autonegegotiate EtherChannel. Setting EtherChannel to desirable or any other negotiable state will never form a channel because the two NICs don't understand PAgP. Keep it on "on" and I think you may need some sort of Channeling software for the NICs as well to utilize Etherchannel. But this I could be wrong on, so if I am please correct me.

Re: Prioritizing Protocols???? [7:24959]
CB-WFQ (class-based WFQ) isn't enabled by default. It is started with the class-map (name), access-lists and policy-map (name) commands. It combines the best practicesof WFQ, WRED and proiority/custom queuing. It is highly customizable. You just create different policy-map's for the different types of traffic (RED data during congestion but not voice, give RTP from site A to site B priority, etc) If the original poster is just trying to pritorize only telnet traffic above all alse, there is absolutly no configuraton needed, cause WFQ is default below E1 speeds and telnet is by default already prioritized above all other traffic conversations. I was thinking the poster had other types of traffic like FTP, http, SMB traffic, etc., which is why the interleaving comes into play, (especially the FTP traffic). I can almost guess that Telnet traffic alone wouldn't starve any traffic out (around 23 bytes/packet or something like that) and interleaving it wouldn't touch it at all, since it's below the 80 bytes that interleaving would chop at on a 64k link. Furthermore, if the link is constantly backed up, I'd upgrade bandwidth, as queuing is only supposed to be used when there is intermittent congestion. If I could type 90 words a minute, I'd write a book too :) ""Priscilla Oppenheimer"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > At 01:35 PM 11/2/01, VoIP Guy wrote: > >I would use CB-WFQ, over all the others because of the control you can > >create. > > > >Protrity queuing will "starve" out the other protocols if one is given > >priority over the others and it is busy. > > Yes, but Telnet may not be so busy that it would cause a problem.

Re: Prioritizing Protocols???? [7:24959]
I would use CB-WFQ, over all the others because of the control you can create. Protrity queuing will "starve" out the other protocols if one is given priority over the others and it is busy. Frame-relay Fragmentation (FRF.12) is an interleave and traffic shaping comand, and as such will minimize seialization, but not prioritize. I would use it, but in concert with WFQ.
