Re: Monitoring Cisco Router through MRTG [7:36598]
If the router is set up to allow SNMP read access, it will respond to requests for many of the generic (MGMT: 1.3.6.1.2.1) objects. So, medium independent error statistics may be gathered on a per-interface basis by querying relevant instances of 1.3.6.1.2.1.2.2.1.14 (inbound)and 1.3.6.1.2.1.2.2.1.20 (outbound). IIRC, layer-2-technology-specific data may be found in branches of 1.3.6.1.2.1.10 (transmission), including more relevant and detailed error counters. You might be able to get similar information from the proprietary cisco MIBs, but using the generic ones where possible tends to simplify your MRTG implementation in multi-vendor environments. The specifications for the MGMT object definitions are available via several RFCs/STDs. - Original Message - From: "Ziyad" To: Sent: Wednesday, February 27, 2002 12:15 AM Subject: Monitoring Cisco Router through MRTG [7:36598] > Hi All > > Can anyone tell me if I can use MRTG for monitoring CRC errors or broadcast > ???

Re: speaking of PIX clones [7:36593]
if you ever want to see something funny, tell a customer in the presence of a Cisco account team that the customer should sell his old stuff on eBay rather than trade it in to Cisco. if looks could kill... on a more serious note, while Cisco can make a very good legal case against folks who buy used routers, then download new IOS images, I think it might be very difficult for them to take legal action against people who sell used Cisco equipment, or those who buy. This ground has already been covered with used PC's, used IBM computer and terminal equipment, used cars, used books, etc etc etc. ""Mike Sweeney"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > I just heard from a friend that a SonicWall rep was saying(dont you love 5th > hand news) that Cisco is planning to crack down on PIXes being resold on > Ebay by killing any and all support for them.

RE: feature packs and licenses [7:36555]
I'm a reseller and I asked my Cisco rep about customers who purchased used equipment from Ebay, back of pick-ups, street corners etc. I was told Cisco has no problem with an end user selling their hardware, but the software license is not transferable. This means the IOS you are using on your used router is not legal, so it's no different than getting a copy of a Microsoft CD and license key to run their software for free. Cisco will sell you the IOS by itself, but it's probably as much as a refurbished router from a "certified" resource. So if you're OK with pirating software, then you should be OK using your router with unlicensed IOS. You should not be able to get SmartNet either, but that assumes their serial number tracking is done correctly.

How would they tell this? More to the point, if I buy a router from ebay to build up my lab, do I need to be separately buying an IOS pack ? I read through the license agreement on the software download part of Cisco's site and find myself no further forward - it would suggest that feature packs have to be sold with a router, and possibly even that second hand feature packs won't do but new ones need to be bought from Cisco.. anyone comment and clarify this for me?

Re: Re: Sample Rate [7:36566]--long reply [7:36566]
Well, according to a voice manual I have, "Lower bandwidths need less expensive equipment, which affects the sound quality... this was determined to be the best cost-performance trade-off". So I think it was reasonably arbitrary. My ancient but still useful Tanenbaum (Computer Networks) doesn't seem to give any reason, which sort of supports that. Horak's "Communications Systems and Networks" agrees that it "is considered sufficient for voice communications and certainly is more cost-effective than if full-fidelity voice were to be supported." And by the way, most references I have refer to the range as being 200 Hz to 3500 Hz, not 4000Hz - for noise I think - Nyquist assumes a noise-less channel.

RE: Re: Sample Rate [7:36566]
In the Cvoice class I attended, my instructor answered the reason why it was 4K as there were 2 groups wanting different rates, so the compromise between them was 4k.

It sounds like it was simply an arbitrary decision. 4KHz is sufficient for a telephone call and to provide clear calls that included higher frequencies might have added some technical complexities, perhaps. They also added a high-pass filter around 400Hz since most telephones can't reproduce low frequencies well and it also filters out some harmonics of 50-60Hz hum that might show up from time to time. That is concrete reason for including a high-pass filter and I wondered if there was a concrete technical reason for including the 4KHz low-pass filter. From the sounds of it there really isn't a technical issue, 4K is just a nice round number. :-) I've actually read that they limit it to around 3.4KHz, but if you sample that at 8KHz you'd be well above the Nyquist limit.

RE: Sample Rate [7:36566]
The reason is for economics. The 300hz filter to 3300hz filter would carry the voice fairly well so this is the least amount of bandwidth to do a decent job of it. Not too much is lost because the voice is between 100 to 5000 hz. The hearing range is not considered as far as I know...

Re: Re: Sample Rate [7:36566]
Exactly, that's what Priscilla and I both just said. :-) What I'm trying to find out is why the original 4KHz limit on voice calls was put into place. It sounds like it was simply an arbitrary decision. 4KHz is sufficient for a telephone call and to provide clear calls that included higher frequencies might have added some technical complexities, perhaps. They also added a high-pass filter around 400Hz since most telephones can't reproduce low frequencies well and it also filters out some harmonics of 50-60Hz hum that might show up from time to time. That is concrete reason for including a high-pass filter and I wondered if there was a concrete technical reason for including the 4KHz low-pass filter. From the sounds of it there really isn't a technical issue, 4K is just a nice round number. :-) I've actually read that they limit it to around 3.4KHz, but if you sample that at 8KHz you'd be well above the Nyquist limit.

I understand all that, but what I don't remember is why there is a 4KHz low-pass filter on voice lines. I know I've read the reason before but I just can't recall what it was. Was it simply arbitrary? A 4KHz upper limit is obviously sufficient for voice quality. Did someone just pick that limit and filter out everything above it, possibly to filter noise or something?

Single user for dialer pool on Ras [7:36589]
I have been tasked with giving a vendor DLSW connectivity through our RAS(3640) using a 1660 with a modem on the aux port. Everything works fine I just need to have the router get the same ip address everytime it logs on so I can use that ip address for my DLSW local-peer. I know you can do it with Radius but I am not very good with that and I need a workaround so I can define a single user a ip address. Any thoughts? Thanks in advance.

Re: Re: Sample Rate [7:36566]--long reply [7:36588]
All right, John-- A couple of years ago (discreet cough), Cisco gave away copies of books as promos. One was _IP Telephony_ by Gorlaski and Kolon (McGraw Hill, 2000). GOOD BOOK. On pp 77-78 is an explanation of the Nyquist rate and voice sampling: "...Thus, if an analog voice signal reaching up to 3400Hz is to be sampled at the Nyquist rate, the sampling frequency must be at least twice that, or 6800Hz, or samples per second. "Sampling does not have to be done at the Nyquist rate. The Nyquist rate is a minimal requirement to reproduce the input waveform, but sampling can be done at rates higher or lower than the Nyquist rate. If sampling takes place at rates lower than the Nyquist rate, the result is distortion of the waveform known as (italics) aliasing. Aliasing just means that there is more than one output waveform that fits the 'connect the dots' pattern of the samples. There is no aliasing ast the Nyquist rate and above." They go on to point out that, by sampling at a rate above the Nyquist rate, you have more than the minimum required information to reliably reconstruct the voice signal at the destination. This allows you to lose a few samples in transit (not that such things would ever happen, of course) and still have only one possible reconstruction. Sampling at 8000Hz means there is a 4000Hz voice bandwidth (overly generous but convenient because 4 is a power of 2 and that makes it easier to code in a binary system). And from the 8000 samples/sec, each of which sends 1 8-bit word, we have the DS0 of 64000 bps (why only 56000 bps may be usable is a separate issue, having to do with signaling on telephone links).

Re: Re: Sample Rate [7:36566]
This is OT, but the upper limit of human hearing is actually around 20KHz at best and usually drops to around 16KHz or so. If your upper limit starts to drop below that you'll start to notice that it's difficult to hear clearly. (Sorry, in my other life I'm a sound engineer and musician.) I've heard that the 4KHz limit is because there is a low-pass filter used for voice. I can't remember the exact reason, but that information plugged into the Nyquist theorem explains--as Priscilla mentions--why a DS0 is 64Kbps.

What would be the point? >When I do a "show span" on switches, It's showing you info about the spanning tree process, not the tree. From my new book (copyrighted by me, and please don't copy without giving me credit ;-) A tree is more than just a woody perennial plant with few limbs on its lower part. A tree is also a mathematical concept. A tree is a diagram or graph that branches from a single stem without forming loops or polygons. A computer network is usually not physically constructed as a tree because of the requirements to provide redundancy and avoid any single points of failure. STP prunes the physical topology of a bridged network into a logical tree topology. Topology is more than just a word that Cisco and other vendors throw around when discussing network design. Topology is a branch of mathematics concerned with those properties of geometric configurations which are unaltered by elastic deformations such as stretching or twisting. (For example, did you know that according to topology principles, a donut is the same shape as a coffee cup? Think about it!) To understand a tree topology, think about a document outline, a table of contents, a hierarchical org chart, cluster diagrams used in brainstorming, and genealogy charts. These are all trees. Unless brothers and sisters or cousins marry, (which does happen sometimes), there is a single path between any two people in a genealogical tree. In a bridged or switched computer network, STP ensures that there is a single path between LANs. STP allows bridges to discover a loop-free, tree-shaped subset of the physical topology that spans the bridged network. In other words, STP produces a spanning tree. NOTE: With networking, as with mathematics, the tree is usually drawn upside down. The root is placed at the top of the drawing. >I do see the blocked port listed >but on testing material I have seen both answers: one reference says >blocked ports are part of the spanning tree another says they are not. > >Which one is true? > >Question (3) > >What is the difference between a BPDU and a Configuration BPDU?

There are two types of messages: Configuration BPDUs and Topology Change Notification BPDUs Once the logical tree has been formed, BPDU traffic continues endlessly. The Root Bridge sends configuration BPDUs out all its ports every Hello Timer interval, which is every two seconds by default. Configuration BPDUs arrive at the Root Ports on bridges downstream from the root. These bridges send configuration BPDUs on their Designated Ports. Topology Change Notification BPDUs happen when there's a change. They travel upstream. Read up on how the protocol behaves. You'll need to know it and it's very interesting.

Re: Sample Rate [7:36566]
Usually thought about in analog to digital conversion, it is the number of times per second a piece of data is captured. Accepted theory states that for the sample to be an accurate representation of the data, the sample rate should be twice the highest frequency you are trying to capture, so for an audio cd, the rate in the lo 40khz range is deemed adequate.

Bit / bytes [7:36562]
Is conversion of bits into bytes and vice versa a function of Layer 1 or Layer 2? I have seen contradictory info.

I don't think he needs to worry about reprise from Cisco if it is just for study. I'm interested in this too but from a tinkering "how does it work" perspective. There are lots of confusing things about the pix software install/upgrades/downgrades and then add in the activation keys and serial numbers. Not even close to the confusion of trying to upgrade catalyst supervisor engines from 2 to 5 and having to go one step at a time.

Spanning tree Protocol Questions [7:36559]
Question (1) Is the first part of this statement correct? I have looked at the 801d paper for an answer but I am still uncertain. "In blocking mode, an interface will receive and send BPDUs but not send and receive data traffic. " Question (2) Are blocked port considered part of the spanning tree? When I do a "show span" on switches, I do see the blocked port listed but on testing material I have seen both answers: one reference says blocked ports are part of the spanning tree another says they are not. Which one is true? Question (3) What is the difference between a BPDU and a Configuration BPDU?

feature packs and licenses [7:36555]
I'm a little confused about the licensing with regards to routers. Someone indicated to me recently that they could tell from a show ver that the router in question wasn't running the code it was shipped with, but I didn't get time to check this out further. How would they tell this? More to the point, if I buy a router from ebay to build up my lab, do I need to be separately buying an IOS pack ? I read through the license agreement on the software download part of Cisco's site and find myself no further forward - it would suggest that feature packs have to be sold with a router, and possibly even that second hand feature packs won't do but new ones need to be bought from Cisco.. anyone comment and clarify this for me?

Subject: How to get the activation key for my clone Pix?
Hi Everyone,
After struggling for the past two days, I have
successfully cloned a Pix firewall by using my PC.
I plug the 16MB flash card into the PC's ISA slot
and the PC recognize that it is a Pix flash card
(cost me $400.00). It boots up fine and everything
seems to be in order. However, after the boot up
sequence, it asks me for the activation key. I've
been trying many different possible scenarios without
much success. I even tried to use the activation key
from another Pix firewall but that doesn't work
either.
Anybody know how I can fake my clone Pix with a
fake activation key? By the way,I am running Pix OS
code version 6.1(2). I even tried 5.3(1), 5.3(2),
6.0(1) and 6.1(1) and one of them works. By the way,
the PC has 128MB of RAM and a 16Mb Flash ISA card.
I tried to clone a Pix520.
Please help.
Jason

I was thinking all the changes were related to possibly troubleshooting in a panic, removing and replacing cables, etc. This isn't meant as a criticism. It's just a possible explanation for some of the weirdnesses. Another weirdness was that the router sent 18 keepalives with no ACK before giving up. It's supposed to only send 3. But I think it must have kept sending as the link flapped. We need more data to help troubleshoot.

You got a good price on the flash card However, this is not a wise move. Bad karma to do this installation anyway... Worse karma to ask for help on a public list with numerous Cisco people on it! (grin) Anyway, the activation key is tied to the serial number, which of course is on the flash card.

Re: How to get the activation key for my clone Pix [7:36536]
The activation key is tied into the serial number of the PIX (I assume the serial # is somehow related to the flash card) so using the key from one PIX will not work in another. I had to RMA a PIX 515 a few months ago and needed to send Cisco the new serial number and they sent me the new activation key later that day. The 56-bit key is free, though, from CCO, but you still need your serial number.

Re: Naming Conventions [7:36535]
RFC 1178, RFC 2100, and RFC 2219 http://www.ietf.org/rfc/rfc1178.txt http://www.ietf.org/rfc/rfc2100.txt http://www.ietf.org/rfc/rfc2219.txt It doesn't clearly tell the location, company, and function of the device. That's a bad practice. You might want to try looking at this instead: http://telecom-info.telcordia.com/site-cgi/ido/index.html Do a search for "Common Language". This is the telecom standard for naming conventions like CLLI, CLEI, CLFI, CLCI What I've found to be useful for TCP/IP-based networks is to use DNS or LDAP (or possibly another database, but both of those are best suited to do this kind of stuff) to contain the "extra" information. A lot of people use SNMP to do this, as well, but it's limited in comparison to DNS and LDAP. Things like LOC, SNV, and even TXT DNS resource records can handle this type of information rather well. I've always appreciated RFC 1178 in combination with a single block of IP addresses for loopback addresses. This way a router's loopback address and hostname stays the same from the day you first configure it to the days of it's largest packet pushing moments to the final day when you brush the dust off of it in the storage closet to trade it up for new gear. And what's really wrong with naming a router "fluffybunny" anyways? All of this really depends on your organization. If you are strict Telecom and follow Bellcore/Telcordia and ISO/IEC guidelines, then by all means, go with Common Language. If you are a new world TCP/IP network - use RFC 1178 for the A records, RFC 2219 for the CNAME records (like www, ns, ldap, as well as machine-parsable names like sjc1-br01). If you are something in-between (both Telecom and TCP/IP) then do both (maybe they should be or already are separate networks with separate administration anyways). Combining IP address management, DNS, LDAP, and Common Language would be a *very* cool project. I don't believe that any IP address should have more than one DNS A record because CNAME records should be used instead for simplification. You could also do a zone dump of just the A records and then know that you have no duplicate IP addresses. This isn't really well known, and I would be willing to bet that my ideas are not universal (which is really too bad). A lot of people have very strict ideas about "Naming Conventions" that don't follow any standards. Maybe there really isn't a standard just because the network operators have not yet agreed on one (visible by the various naming implementation differences). -dre ""Richard Tufaro"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Hey Im looking for a good naming convention that clearly tells the location, > company and function of the device.

CCDA passed [7:36543]
Decided it was a shame not to do the couple of exams to get to CCDP, so got hold of the Cisco Press DCN book last week and took the exam today. Managed a 922, although I wasn't even sure that I'd passed as I hit the final NEXT button. I was totally bored through the whole of the book and the exam did the same for me. The feeling that you're putting in gibberish, just because that was the answer when the test was written is not a good one. Not to worry, I'm hoping the CID is a little better, but I hear it may not be? I get the book next week - wishing for some interesting topics but not holding my breath.

HELP !! CCIE 2B or NOT? [7:36542]
Hi all: I have a dilemma that I was wondering if I could ask your opinion on concerning CCIE status. I am a Network Admin for the cisco lab at a university. The racks of equipment in the lab is available to use for any BGP, VLAN or multicast network possible it seems like. But I'm at a point in my life where there's a fork in the road; it looks like the CCIE route or MBA route and I am leaning towards the MBA with a lower cert like CCNP. But with all this equipment and abundance of lab time here, would I be foolish not to take advantage of this situation? And suppose I do go for it and hope that I pass the big one, I'm curious what kinds of jobs are out there in this industry for someone like myself with 5 years of experience, 1-2 years of it concentrated in IT? What should I do?? Thanks.

Re: written exam passed [7:33460]
I sure did not get the same test you did. I used the boson tests to verify verify my knowledge before takign the written exam. I was scoring 85%-95% first time taking them and only got an 81 on the written today. For me there were probably 5 questions that were quite similar and only 2 that were identical.

Re: Was Re: Where is Bruce Caslow ECP1 Class? [7:36501]
I agree, and the key words there are 'if you can afford it.' Some of these types of classes come out to almost $1,000/day! And while I agree that the instruction you get is incredibly valuable, it has to be justified. If you can afford to pay it out of pocket without going into debt, great. I'd bet most people aren't willing to fork over $4,000 in cash so they'll put it on a card. Many people want the CCIE certification because it increases their marketability and the likelihood of a really excellent salary, and that's why they're willing to shell out huge bucks to get it. But if the financial rewards are less likely, is it worth it to fork out this much cash on a single class? Just a thought. There's no doubt in my mind that if I had the cash I'd take of one these courses in a heartbeat. However, with a mortgage, two cars, two dogs and a kid on the way, my wife would kill me if I even suggested that we go into debt an additional $4,000 on *top* of all the money I've spent on books, practice labs, and routers. Like I said, just a thought. It seems they're pricing is based on demand figures from two years ago. Then again, they wouldn't be charging that much if people weren't paying it! In hindsight, I guess I don't really have a point and I'm babbling. :-) John >>> "James Haynes" 2/26/02 12:19:07 PM >>> Chuck, Well said.

We have an extra NM-HDV in the office and if it were possible, it might get me a suitable ISDN simulator without any extra cost. Someone had mentioned there was a possible new feature in 12.2 to permit this? Anyone care to comment or revisit this?

Re: ATM question [7:36496]
not to be a smart ass, but it depends. below are some ideas based on what my local telco offers: wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Greetings all, > > Couple of general questions about ordering ATM services. > > 1- At what increments can I order ATM from a service provider this is dependent upon the local telco. in this area thre minimum is ATM T1 - 1.54 you can order 1, 2, 4, or 8, and use IMA to inverse mux them. after that the local telco here offers 25 mbs and 45 mbs. and so on. > 2- What kind of termination equipment normally used (ATM DSU, etc) depends on your decision based on #1. T1 ATM would usually terminate on ATM IMA equipment. this can be a router blade, or an external box from someplace like Adtran of Kentrox ( yes I know they changed their name ) up to 45 mbs would probably come in on a DS3 electrical ( coax ) but more likely the telco would hand off fiber. OC3 and up would definitely be fiber. > 3- what are the cost for ATM services. depends on the local telco. I don't know pricing off hand as I sell equipment and the telco people sell transport. I believe that a T1 ATM around here is about the same cost as a regular T1 > 4- Please add anything here that might be relevant to my above > questions. keep probing your provider - ask a lot of questions. get a second opinion from a different provider. keep in mind that prtoviders will charge you in part based upon the pricing they get from theri telco.

Re: Was Re: Where is Bruce Caslow ECP1 Class? [7:36501]
Take a lesson from the financial markets. Call this an investment in the future. The best time to buy stocks is when they are low. ( duhh ) The best time to educate and improve yourself is when the market is slow. Now is the time to invest in yourself - training, experience, whatever you can get. the market is starting to come back. it's hard to tell, but this is because jobs are a trailing indicator. Companies will delay new hiring until they are certain the market is recovering. The economy is indeed recovering as we speak, according to the leading indicators. This will not be reflected in the current job market. We may not see the job market improve for several more months. But I can tell you, I'm seeing a lot more in terms of customer activity than I was seeing six months ago. Or three months ago, for that matter. the biggies are VoIP and VPN, but there is a good share of infrastructure upgrade. Without the idiots from defunct places like M1 mucking up the dialogue, customers are getting better advice IMHO, and are seeing the value of investing now. I suspect the real question here is whether or not there is value to being a CCIE as opposed to some other certification, or expertise in networking in general. We could debate this point until doomsday and never come up with a definitive conclusion. IMHO the skills acquired during the CCIE Lab prep process are valuable. The cert itself may or may not be of value to a particular employer. My own opinion - always invest in yourself. Invest in the skills that will keep you challenged and keep you employed.

How Faceless the CQS Logos are??? [7:36521]
Hello, I know the focus of any certification is not the certificate nor the logo, the joy of scaling through all the hurdles, the additional knowledge and responsibilies it brings, etc out weighs the the certificate or the logo you are given to put on your complimentary card of letter heading. However, the logo and the certificate, etc should be appropriate in terms of quality, representations and designs, no doubt it adds some prestige both to the holder and the vendor. I was disappointed to find out that the Cisco CQS certification in so faceless. All that you see in the logo is "Cisco Certified"...No indication to the type of certification, no mention of anything relating to it whatsoever. Logos are normally graphical representations, But Cisco logos are not, no one who sees the CQS logo will know what it stands for nor what it represents. I think Cisco can do more, they have the money and resources. sometimes we had to pay through our nose to get these certifications, It is only fair one get value for his hard earned money. It also tell how serious, dedicated and committed the vendor is to their certifications process. If Cisco would commit half the money, strength and vigor they currently exhibits in pursuing and executing their NDA into this, it would go a way to add more value to the whole process. I thought someone shares the same thought with me. Enjoy. Godswill Oletu CSS1,CCDP,CCNP.

catalyst 3548XL Question [7:36518]
I have 8 cats separated on 2 floors and I want to create some sort of
failover but want to make sure that it will work and will not cause any
problems. The diagram below is my setup and I have 4 cats on fl1 connected
to 4 cats on fl2 via fiber from sw4 to sw5 but I would like to run a piece
of fiber from sw1 to sw8 as well if 3 or 4 goes down. Can I do this without
causing any network interruption?? And is there any special setup that
should be done to stop routing loops?? Such as enable STP?? They all are
in the same VLAN of 1. No special VLAN configs have been created.

RE: Serial interface problem [7:36423]
I don't think Cisco publishes what the hex codes mean after the "new serial state = 0x" line. Anyone know? I did find reference to something generic that read "hardware has interrupted the software." You seem to have a lot going on in that regard. Every four or five seconds on both ends of the link you are experiencing one or more hardware interrupts. As a last resort, I would look into control lead options (no pulse, ignore dcd, etc). Actually, the TAC would certainly have access to those code values so they would be my true last resort. It's difficult to say which is the horse and which is the cart. Are your routers not successfully exchanging keepalives because of the hardware activity or is your hardware activity the result of not exchanging keepalives? If I recall, dtr is supposed to pulse once, then again in 5 seconds, and then every 30 seconds until the protocol comes back up. I have no idea what dcd and dsr are supposed to do when running as a dce.

Was Re: Where is Bruce Caslow ECP1 Class? [7:36501]
I'm curious about the feelings others have toward this sort of class, especially considering the current job market. A couple of years ago if you had CCIE on your resume you were almost sure to get an outrageous salary with bonues and other killer benefits. This more than offset the cost of taking these sorts of classes. In the current market, I've heard that if you have a job position that requires a CCIE you'll get ten applications! With the HUGE numbers of unemployed engineers--of course, depending on where you live--it is no longer a 'sure thing' that you'll even be able to find a job, let alone get those huge salaries that made everyone salivate. So, if you had to pay for something like this out of your own pocket, do you think it's worth it? Do you think a one-week class that costs over $4,000 will pay off more in the long run than spending a fraction of that on a few more routers and some books and then putting in an extra month or two of practice and study? Here in Denver the market REALLY sucks right now. Even if I pass the lab the chances of me moving to a different company--and therefore getting a better salary--are slim to none and Slim might have just left town. I guess what I'm getting at is this: do you think these types of companies are pricing themselves right out of the market based on demand figures from a couple of years ago? Or, do they seem to be operating on the premise that as long as there are people willing to pay exorbitant prices, they'll charge sky-high prices. What are your thoughts?

Re: CS11152 SSL Not working [7:36505]
We have the same issue here, but since our physical web servers run both a secure and unsecure site, we simply use ping for the secure service and an http get for the unsecure service. If we see the unsecure site go down, we know users won't be able to get to the secure site either. If it were possible we could get away with turning off keepalives on the secure site since it's kind of pointless. I believe it's possible to setup scripted keepalives where the CSS actually logs into your secure site but that's way to much work. :-) John >>> "sam sneed" 2/26/02 9:58:54 AM >>> I was thinking the same thing but I did not try that.

I'm testing the connection to do VoIp between a remote site (Cisco 1750) and a Central site (Cisco5300). The AS5300 is only connected via LAN. The WAN connection in Central Site is made with a Cisco 7140. The 3Com NBX emulate the PBX. We have try with diferents isdn type Switch and signaling but it no work. Always appear "BAD FRAME..."
