Re: Upgrade license [7:70919]
I believe it's just a new activation key. Copied from Cisco's website: There are a couple of reasons that you may need to upgrade the activation key on your PIX. a.. Your PIX does not currently have VPN-DES or VPN-3DES encryption enabled. Note: VPN-DES encryption must be enabled for you to manage your PIX using PDM. Registered users may obtain a free 56-bit VPN-DES activation key by completing the PIX 56-bit License Upgrade Key form. VPN-3DES activation keys must be purchased through your local reseller or Cisco sales representative. b.. Your PIX currently does not have failover activated. c.. You are upgrading from a connection-based license to a feature-based license. -- RFC 1149 Compliant. maine dude wrote in message news:[EMAIL PROTECTED] Hi, Can someone please tell me the process of upgrading a restricted license to a unrestricted one a PIX firewall please.

Of course, the following fields may change, however: (1) options field (2) more fragments flag (3) fragment offset (4) internet header length field (5) total length field (6) header checksum Also, with the options field, options may or may not be copied into each fragment.

Re: Off Topic - Missed it by that much - CCIE Lab report [7:58587]
was your problem split horizon? The Long and Winding Road wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... In the words of the esteemed Maxwell Smart, missed it by that much. Good test. Liked it a lot. Can't say much about the content, obviously. The 3550's were there. I think that those who have expressed reservations about this will find little to worry about. The Lab writers did a pretty good job of integrating the devices into the rack and the exam. I think I was more surprised by what I did NOT see than by what I did see. Wish I could say more. There were the usual off the wall requirements. I knew the names, or had heard of the technology, but had never practiced it. Here's where the doc CD came in handy. It was very easy to locate the information and do the required configuration. I did have one very odd problem I was unable to solve. My own practice, not to mention the doc CD configuration guide, told me that a particular configuration should have worked. But it didn't. I've mocked up the configuration here at home, and it took a total of 10 minutes to start from a router with no configuration and have it up and running correctly. But in the Lab it just would not work. I have an inquiry in to the CCIE Lab folks, asking them to check the rack. I believe there is a physical problem, although for the life of me I cannot come up with a plausible explanation as to why. I would get more specific, except this would be a direct violation of NDA. I will say that anyone who sits at rack 12 in San Jose - if you are absolutely certain your configuration is correct, tell the proctor. I hesitated to do so, and I paid the price. You'll know when you see it ;-) I did one stupid thing, and the more I think about it, I should have corrected it immediately when I discovered it. When I first created my notepad file with my alias commands, I stupidly did most of them as alias configure rather than alias exec Given that the lab is graded pretty much by scripts, I have this bad feeling that this mistake may have interfered with the operation of some of those scripts, meaning that I was not given credit for successfully completed tasks just because the script was unable to function properly. You are no longer given a point total in your report. When I counted up points in the late afternoon, I thought I had between 60 and 70. I had no reachability problems, save to one interface, and that interface had nothing depending upon it. I knew I didn't have enough points to pass, but I thought I was close. To judge from my score report, the final total was maybe 35-45 depending. As those of you who have been there know, the dependings will kill you every time. :-) I can say I had a lot of fun doing this test. That's probably part of the reason I failed - I'm having too much fun. I can also say I'm hot to trot. I can taste it. I'm yay close to passing, and I want back in as soon as I can get there. You can bet I'm checking CCO regularly for those open dates. Afterwards, I had the pleasure of hooking up with groupstudy regular Larry Letterman. Larry - thanks for the tour - it was impressive. I was reminded of exactly why I got into the tech business in the first place - the desire to do things like you are doing, important things, things that keep businesses competitive.

Re: is there anyone migrating isdn backup to dsl b [7:58568]
I say DSL has no multi-service (or very limited) capabilities. There isn't much in terms of QoS, LFI or other voice/video tools. Plus there is no QoS across the DSL network (if over Internet) and no standard nation-wide (no National provider). If you say, there is no voice going across network, or video, then you are doing your client a dis-service by providing no upgrade path towards that eventual path. Priscilla Oppenheimer wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... It sounds like DSL has a low mean time between failure (MTBF) but a high mean time to repair (MTTR), which can be just as bad, especially if it's your only backup. Of course, your mileage may vary (YMMV), depending on the service provider. Also, a service level agreement (SLA) would help, as Chuck mentions.

Jenny McLeod wrote in message news:200211140127.BAA14210;groupstudy.com... OK, I'll admit this is a real-life problem, not strictly a study question. I have a couple of OSPF adjacencies that refuse to start up. Just to make this entertaining, these are not router to router - they are Cisco to mainframe, over a CIP. Five IP stacks neighbour the router - two are OK, three get stuck in EXSTART/EXCHANGE. The five IP stacks also connect to a different router, and these adjacencies are fine. It looks to me like the classic MTU mismatch symptoms, but a printout of the m/f definitions shows the MTUs to be 4096, as does show int on the router. I'll get the m/f guru to check the definitions for white space - I don't know if that will affect it. There have been various m/f changes lately (and a couple of router ones) errors may have crept into the configs. What has me baffled is some of the debug output from the router (debug ip ospf events). Nov 14 11:51:14.121 ESuT: OSPF: Rcv DBD from x.x.x.x on Channel6/0 seq 0x3DCDF2DA opt 0x2 flag 0x7 len 32 mtu 0 state EXCHANGE Nov 14 11:51:14.121 ESuT: OSPF: Send DBD to x.x.x.x on Channel6/0 seq 0x3DCDF2DA opt 0x42 flag 0x2 len 1472 The debug doco isn't particularly detailed for this command, but I assume opt refers to the options field. RFC 2328 seems to think that the first two bits of the options field should be cleared, so the value of 0x42 being sent by the router surprises me. Obviously the value of MTU being reported in the received DBD is also a concern! Other debug output indicates that the m/f sends the same DBD several times (same seq), which the router acks, then after this is received several times the router claims Nov 14 11:51:20.037 ESuT: OSPF: EXCHANGE - OPTIONS/INIT not match Nov 14 11:51:20.037 ESuT: OSPF: Bad seq received from 92.1.2.20 on Channel6/0 Is anyone aware of any other gremlins that cause similar symptoms?

Re: Storage Area Networking [7:56857]
We in the Cisco world are just entering the SAN arena, but it isn't new technology. The only new thing will be iSCSI. My company is HP and EMC's largest reseller, so we have been doing this stuff for a while, but it's brand new to me. I have been picking everyone's brains the past few months to understand what all the hubbub is about in the SAN arena. Here is what I have learned so far. The obvious: First off you need a off disk place to store the data should the HD fail. In the beginning there was the tape drive, usually connected to the same SCSI bus as the hard drives of the server. Since everything was SCSI, and local to the server, it was quick and speedy, and you didn't have to worry about disc timeouts, LUN addressing, or distance etc.. The limitation was obviously the challenge of managing potentially hundreds of tape drives. So someone came out with the idea of creating a large disc system that many servers could connect to via SCSI. This offered a more centralized solution for locally connected servers, but if a large company had many clusters of servers over a large city, state, country, continent and so on, this solution couldn't meet that need since the servers still connected to the central disc system via a SCSI bus. What was needed was a way to transport data over a network. At those times, 10/100 Ethernet was not fast enough, both because of the 100MB limitation (VS the GB speeds of a local SCSI bus) and the MTU of Ethernet. If I tried to transfer even a 512 byte chunk of data from a SCSI HD to another over Ethernet, the HD would timeout and give errors. I think this is where FC came in, with initial speeds of 1 GB and a direct encapsulation of raw SCSI data, eliminating the timeout issues and the MTU size, as a raw file could be large than 1500 bytes. The FC spec also offered a way to address LUN's on servers. The only problem I can find with FC is that there is no standardization as each FC switch vendor offers it's own flavor of FC, which in turn needs it's own approved FC cards for the server and each vendor of server/disc system needs to approve it's use. The next step is iSCSI, which will offer vendor interoperability and eliminate the separation of IP and FC networks. On the LAN end, Cisco is going after Brocade with a new Switch in the 9xxx family (can't remember the exact name) that, from a technical issue, beats any Brocade switch hands down (now if only the EMC's, HP's, Hitachi's and IBM's would certify it). The 9xxx has 128 ports on 1 bus, vs a large brocade that has 32 ports over 2 busses, for a total of 64. Not only that, the 9xxx switch looks like a Cat 6k, and therefore is modular, and can combine FC/IP/iSCSI all in 1 box. Cisco hasn't come up with a go-to-market strategy yet, but I have met with one of the Technical Product Managers at Cisco, and it's coming any day now, so expect to see Cisco go head to head with Brocade. That may tackle one issue, but I have other needs where I need Cisco today: Now the big thing is DR, where I can back up data over WAN's to a remote DR site. The problems I am encountering now is two fold: I can't use a Cisco WAN router to take FC on LAN end and send over WAN such as a T1 or T3. I have customers doing AVVID and storage, but it's over IP, and not FC or iSCSI. Cisco is off on the right foot with AVVID, but it needs an S at the end (S is for storage). Once I can combine all 4, (from what I can gather, storage is just another application with it's own needs- *CAN* use a ton of bandwidth and is latency sensitive like SNA or Video) I can tell large, LARGE enterprises that we have a great DR solution. I don't think that SAN's are for most companies, just the large ones. The other problem I have is that none of the Cisco gear is certified, and it doesn't matter how awesome Cisco's gear is, if the vendors won't certify it, then they will fail. If I had to add a third problem, I'd say iSCSI hasn't lived up to it's hype yet, and there are very few products (servers and disc systems) out there that offer native iSCSI. I am not a SAN expert, but I have seen more companies willing to invest in a SAN than a IP Tel network, so it's a good thing to learn, but not today.

Re: Public Internet Access [7:55898]
I guess policy routing is what I'd recommend, or put a firewall in front of the servers and set up the appropriate controls. Policy routing is what that type of application was inteded for, so you are along the right track, although it's far from secure. If security isn't an issue, then check out a firewall. If you got the cash, get the firewall blade for the 6500, and implement the controls there. Then you have optimal control over all aspects of the network that pass through it.

Re: run VoIP on a frame network at BIR instead of CIR rates [7:55833]
This was Cisco's old theory. In theory, it would work, but in reality, if the frame switch saw a packet come into it's ingress interface with the packet already marked DE, it will drop it because it was unexpected. I asked the telco's your question last year and that's the answer they gave me.

Here are my thoughts: What if the router were to pre-mark all data packets as Discard Eligible (DE) on the outbound serial interface connected to the frame network.

The SEP stands for Selius Ethernet Phone, and the numbers are the MAC
address. A gateway has a different 3 letter code, can't rememner it though,
and it all depends on the protocol it uses, such as mgcp or h.323, as the
latter doesn't have identifiers.

I think wireless and converged data over high speed links wil co-exist, not compete for same space n market.

Without that speed over wireless, we are stuck with being able to DL e-mails and web-pages at a slow, but decent rate. The high speed stuff will happed over wires for a while, and although I don't see PC's being used as TV's, I do forsee the PC being the digital gateway/servwer of the high-speed home where other devices like a TIVO work off of the gateway and provide TV services to the family and a phone will be a phone, just getting it's information form same gateway and the phone will provide the phone services for a family. Our consulting side does see wireless devices with two bands - 802.b/a/g for use in hot spots and GSM/GRPS over the WAN, and this is going to be the way of wireless for a while. While your at a hotspot, maybe a hotel or airport (or Starbuck now, which we helped developed for them) you can get high speeds and DL video, maybe play a java game with a buddy. Then you have to leave the area, and now you rely on GSM. You still have connectivity, but in a limited fashion. I work for a company that tests, writes, and demos the latest devices from that carriers, and so I get to play with them as well, and I have seen a lot of innovative devices, (right now I get a T-Mobile Pocket PC Phone Edition as my cell phone) and I love them, but what I'm seeing is not the devleopment of bandwidth over their networks, but the 2.5G network development, and the standardization of the network with 1 common signal. -- RFC 1149 Compliant.

Group, Hoping that someone can help me out with a VoIP QoS issue that I am currently dealing with. I work for a service provider, and I am currently troubleshooting a VoIP over frame relay quality complaint. My end user has a 768K host with four 256K drops dedicated solely to VoIP traffic. My customer states that he experiences intermittent jitter on his calls, but they follow no real pattern. We have had his vendor place test calls, and sometimes 7 simultaneous calls can go through fine while 3 simultaneous calls will experience poor call quality and excessive jitter. The end user's vendor is of no real help with this issue stating that his configurations are fine and the trouble must be with the WAN link. I have verified that the entire network is clean, no T1 performance monitor errors , no input errors on the customer's serial interfaces, and no input errors to my frame switch. No apparent utilization issues, the host averaged 50% port utilization during a 24 hour sniff. We have also verified the drops are not receiving any FECNs or BECNs. I have a copy of the customer's router configurations and his map-class statements appear to be correct as well. His CIR and MINCIR are set to match the frame relay PVC CIR in my network (which I believe means that he has configured the statements to prevent any bursting, please correct me if I am wrong). On to my question. The only discrepancy I find with this customer's configuration is his queuing. On all four of his drop routers he has configured WFQ, on his host he has no queuing specified. Could this be the cause of all of his problems? Would WFQ be the most desirable method? What I have read in the past led me to believe that a fragment statement in the map-class was the most desirable because it activated the dual-FIFO feature on the physical interface. I do not have a great deal of experience with VoIP so all I have to go on right now are theories. Any direction is greatly appreciated.

Re: QoS and CBWFQ [7:55546]
THe only reason I can see using QoS is to limit traffic to certain amouts of BW. Even then it's tricky becasuse in CBWFQ, you are guaranteing a minimum, not a maximum amout of BW for a class. You could police certain classes of traffic to never exceed a BW, but that can be crummy as well, espcially if there isn't congestion. -- RFC 1149 Compliant.

JM Others might disagree but I see no advantage whatsoever to using QoS mechanisms on the link going to your ISP. Would it depend on the bandwidth of his circuit? WFQ is on by default for speeds of E1 and less. Perhaps that's all he needs if he has a low-speed circuit. He probably doesn't need anything special if the circuit is higher speed. For low-speed, he could at least prioritize the order of packets sent (and possibly dropped) by his own router. He should check the circuit speed and load to see if he needs to do anything. Also, it would be silly to make SMTP and POP3 highest priority in many environments. Is there a local e-mail server for SMTP and POP3? If yes, the clients are sending and receiving locally. The server also sends SMTP traffic to servers on the Internet probably, but if that gets congested, the server will simply try again. There's no user waiting around for this. In most cases, server-to-server delays aren't noticeable by users. But if the e-mail server is offsite, then maybe it makes sense to prioritize SMTP and POP3. ___ Priscilla Oppenheimer www.troubleshootingnetworks.com www.priscilla.com Once you hand off traffic to them you're completely at their disposal. You have no control over traffic within their network so why even bother adding queueing to your outgoing interface? If your link is congested often enough that you feel it's necessary I'd suggest getting another circuit installed, if that's possible. Incoming I'd think that CAR would be useful depending on what you're really trying to accomplish. It would at least allow you to classify traffic based on your own criteria and then mark it for special handling within your network.

Even though it's not officially toll quality I consider it toll quality, as I can't tell the difference, and most people couldn't either. Even if using G.711, I can still use compression and VAD to get down to 25K or so, which isn't bandwidth hungry in my book either. I think the apps that will be on a converged network in the future will be bandwidth hungry, such as video. Voice isn't. CL: I don't think the issue is the bandwidth taken by one compressed call. The issue is poisson 99. I think that's how the telco guys call it. What happens when a significant number of calls must go through - say during an emergency? CL: current telco networks are engineered such that you get dial tone 99.5% of the time you go off hook, day or night, busy hour or not. the VoIP netowork must not only operate at that kind of reliability, but must tramsmit data simultaneously. CL: This rush to converged networks means not only reinventing what the telcos have already done, but building out a whole new infrastructure as well. There is at least one school of thought that calls this a dead end.

If my assumptions are correct then the STP run only on those ports which will be uplink to (2) 6509 layer 3 switches. One in forwarding mode and the other one in blocking mode. The GigabitStack ports between the four switches should not be in either a forwarding or blocking port since they are just being used creat a big one virtual switch from the 4 seperate physical switches.

Re: SIP vs H323 [7:53852]
I agree that SIP is the future, it just isn't there yet. There is some SIP being built into Unity and CM, but until everything is SIP (as opposed to MGCP/H.323 and Skinny), it just isn't useful yet. I know that SIP is being deployed in SP networks, and I have implemented it in a Telco, but for enterprise, it's useless. I can't wait til it is developed and more mature. Jason Weden wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Ok, so SIP is nowhere near useless. It is being used all over the place and will eventually replace H.323. Telcos like Vonage (which uses Cisco SIP equipment), deltathree, and Denwa are using it for last mile telephony connectivity for residences and enterprises, and WorldCom, after surfacing from its financial issues, will be using it on its global network as well. Microsoft has built a SIP client into Windows XP (Microsoft Messenger) and SIP is very flexible and extensible and the best place to start is http://www.sipcenter.com. PBX manufacturers like Mitel and Siemens have developed their PBX completely around SIP. To get back to Cisco (as this is a Cisco newsgroup), Cisco has taken the time and $$ to start to develop SIP functionality in its products despite the fact that it isn't need for AVVID at all. Though their initial SIP focus is on carrier-class products (since that is the logical choice -- see my list of companies above), my bet is that SIP will surface as a more central part of the AVVID architecture for the enterprise. A good Cisco link is here: http://www.cisco.com/warp/public/cc/techno/tyvdve/sip/prodlit/index.shtml or here (which displays more enterprise scenarios): http://cisco.com/univercd/cc/td/doc/product/voice/sipsols/biggulp/index.htm Regards, Jason Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=53858t=53852 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: CVOICE book: VoATM and VoFR [7:53567]

The VoFR stuff will probably go away. SIP's the new thing, but not there yet -- RFC 1149 Compliant. Priscilla Oppenheimer wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

Yup, you got it, although it may be even simpler than you imagine. Before AVVID, Cisco did VoIP, VoFR, and VoATM, as discussed in the CVOICE class. With these solutions, you simply connected analog phones to FXS ports on routers. The routers digitized and compressed the dialed digits and the voice itself and packetized it. If it was VoATM or VoFR, there was no IP. The data was simply put into data-link-layer frames (or cells with ATM). You asked about the call-control signaling from the analog phone, but how much would there be? These phones would be your basic $5.99 KMart special with no bells and whistles, so to speak. The router provides dial tone and picks up the dialed digits and forwards them to the other router. As you can probably tell, I'm not a telepony expert, but I have gotten quite a few of these simple voice/data networks up and running. It's very easy. There is no Call Manager! And, as you mentioned, the major benefit is that you bypass long-distance charges because you simply use the existing data network. You may need to prioritize voice, and break up big data packets to get the low level of delay required for voice, but other than that, there's not much to it. The original CVOICE class covered only these types of solutions and I'm sure the book still has a lot of this flavor, although both the book and the newer version of CVOICE also cover newer solutions too these days probably. ___ Priscilla Oppenheimer www.troubleshootingnetworks.com www.priscilla.com -- TT Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=53585t=53567 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: CLI vs PDM [7:49774]
PDM. It's just too easy. Or use CiscoWorks VMS or CSPM to manage a bunch of them. I can't stand the cli and it's archaic language. I'd rather make sure my FW is easy to configure so I don't miss anything. If something is too complicated, you don't even know if you have problems because you are stuck fighting with configs instead of hackers. Although the a basic PIX config is easy to set up, once you start doing complicated large-scale projects and need to have complex configurations, the cli on the PIX gets ridiculous. Just my opinion.

Re: ISP QoS Architecture Question [7:49767]
There are a lot of Cisco Powered networks doing QoS, but more for multi-service type stuff for voice and video. If you look on Cisco's web-site, there's a whole program your ISP can join to become Cisco-powered in multiservice, although I don't know the exact search terms you'd need to find it. If you want to join, Cisco will tell you in technical detail what you need to do for QoS. I imagine it's just stuff under the MQC, but I never bothered to ask. In any case, I don't think giving lowly http priority is the best business decision you can make. It's TCP based so it can handle delay, plus you have no control of the http traffic once the user leaves your network onto another, so all the time and effort you place into it, may be all for naught. Even if you give http A+ traffic rating, as soon as the user goes to another network peer, it may be congested. Just my .02 cents -- RFC 1149 Compliant Jay Greenberg wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... I am considering deploying QoS features in our ISP. The ISP has about 60 thousand users in total, and I was thinking of setting a general traffic policy.E.g., I would like to set HTTP traffic down to a very low delay, to make the network seem faster to end users. I suppose what I am asking is - has anyone done this for an ISP, and if so, how did it turn out?

Re: CCIE Study: CBWFQ / CQ [7:49816]
I haven't taken the CCIE lab yet, but first I'd think they'd want you to use CBWFQ or LLQ, as the rest are just ancient. Cisco is emphasizing AVVID, so you'd probably be tested on avvid technologies. I'd also study NBAR and multicast, among others. Probably dial-peers as well. But I guess if they did ask about old qing methods, it would be someting like this: Use a qing method that gives priority to one q with no regard to protocol starvation. Then you'd use PQ Use a qing method with no PQ and has 5 classes for you to chose from. Then you'd use CQ Use a qing method that is fair to all protocols and gives preference to higer ToS. Then you'd use WFQ which is the default for e1 and below. Use a qing method that meets modern requirements for voice and AVVID. Then it's LLQ Use a qing methid that gives classes to traffic and wfq's the rest. Then that's CBWFQ. Jason Greenberg wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...
