OT - ISDN viability - WAS: Re: VPDN - ISDN problems [7:53931]
I see more complaints / problems / issues with ISDN and DDR in specific and in general, in real world and in test situations. Idle curiousity. Is ISDN really viable in terms of reliability for DDR applications? In any number of mission critical applications, I have seen major vendors, major enterprises, and major service providers use manual intervention as the preferred means to apply dial backup.

Re: SIP vs H323 [7:53852]
In what ways was the SIP equipment better? The fact that it comes from a "www/internet" IETF world, versus H.323 which comes from the ITU, wouldn't necessarily mean that it's better. In fact, to make a very broad generalization, the IETF has historically been involved with data networking which hasn't been that concerned about quality. Reliability is achieved, in general, by the sender retransmitting if there's no ACK, which doesn't work with voice. Quality is achieved by various hacks. ;-) At least in the U.S., our telephone networks have always been way more reliable and offered better quality than our data networks, which have been annoyingly flaky. When we pick up a phone to make a call, unless it's Mother's Day and all circuits are busy, it simply works. Problems are rare. Problems accessng data on intranets and the Internet are widespread. So it doesnt' fit with our paradign that you would think that SIP is better because it comes from a "www/Internet" world. SIP may be better because it's always easier to do something better the second time around. SIP is newer. H.323 is old.

Re: Please Please help!!! [7:53917]
Well, an NM-4A/S is probably cheaper if your NM slot is open. However, it only does 128k per connection instead of the 2-8 mbits of a WIC-2T. WIC-2T's seem to go for about $200-$250 each on ebay. A NM-4A/S seems to go for about $200-$250 on ebay. It may also depend on whether you want to leave your NM slot open for some other card, like an Ethernet interface or an adapter for two more WIC cards (be careful, not all such NM's are usable in a 2600). Biggest drawback is that it uses a different connector than the WIC-2T so you need more cables. Personally, I have a 2600 with a NM-4A/S, a WIC-2A/S and a WIC-2T. It gives me an eight port frame switch, plus I can use RS-232 cables for doing dial-up modem configurations. I suppose I could even swap one of the WIC's for an ISDN WIC for ISDN configurations, although I haven't checked to see which are compatible with 2600's yet. Also, I haven't tried it yet, but I am pretty sure you can use 4 of the serial ports to make a frame relay switch and then use the Ethernet port and the remaining serial ports as an IP router giving you two routers in one box.

Re: Please Please help!!! [7:53917]
You can use an NM-4A/S, but these ports can go no faster that 128kbps. This will also use up your NM slot, which you may want to leave open for something else (like a Voice module). Shop around for these NM-4A/S modules, as the prices vary drastically from vendor to vendor, and day to day on ebay and the ISP-equipment list. I sold mine already.

Destination interfaces or ingress interfaces? I would think you would
disable it on the incoming interfaces to disable the automatic behavior of
using the fast-switching cache when a packet comes in. Correct me if I'm

1720 flash memory issue [7:53919]
Just installed a 16MByte Viking Flash memory card (Viking p/n CS16MC5V) in a Cisco 1720 router with the following Boot ROM: ROM: System Bootstrap, Version 12.0(3)T, RELEASE SOFTWARE (fc1) The Flash appears to work (I can flash IOS images on them), but the router only sees the flash as 4 MBytes total, not 16M. I re-seated the flash card (with power off of course), with no change. The label on the flash card clearly has the p/n and 16MB on it.

Re: Pix performance woes [7:53898]
First of all, the Pix515E is running on an Intel Celeron 433Mhz, not PII. I have customers that have no problem migrating from CheckPoint NG (FP2) over to Pix515 firewall (running version 6.2(2)). At the same time, I've seen customers having problems with the Pix firewalls that I have to migrate them over to CheckPoint NG FP2. I think it all depends on the applications that you are running on those webservers. I may be wrong but I the max. connections that the Pix 515E can handle is around 100,000. The value also depends on the amount of memory available on the Pix (128MB). My question to you is this: 1) Do you terminate any VPN connections to your Pix? If that the case, you should increase the memory to 128MB. The 515E has built-in VAC so you should be OK. As I've said before, it depends on the application running on the servers. It seems that Pix firewall handles short and bursty traffic better than CheckPoint where as CP has better "stateful" than Pix. What version of Pix OS were you running? Symon Thurlow wrote:Hi All, I have a question regarding PIX perfromance. and wanted to see what the experienced PIX crowd here has seen before. I am migrating from two seperate Checkpoint 4.1 boxes running on PC's (PIII 733) to one failover 515e bundle. The 515e has a PII 433 cpu in it. The environment is an online trading shop, where there are 4 trading servers. I changed over on the weekend to the PIX solution, tested everything 3 times, and everything was fine. As soon as users hit the most popular server on MOnday morning (250 remote users through the web, connecting to some custom TCP ports) the response time turned to mud and I had to back out to the Checkpoint solution. Unfortunately, because this company loses so much money when the servers are not online, I had no time to gather any stats (memory usage, cpu usage etc).

Hello, I currently have a Cisco 2620. I am just wondering what would be the most economic / most cost effective way to get 4 Serial Ports in total onto the 2620 (so I can do 4 ports frame etc). I know I can get 2 x WIC-2T, but is there any other cheaper way? And would I need any special cables for them? Would be greatly appreciated if anyone can shed some light on this. Best Regards, H.

Re: token ring rj45 to db9 cabling [7:53860]
Here's the fun part with these connectors: For this "fun" to work, you need the following: [SWITCH]--[Balun1]--[Token-ring wire]--[Balun2]--[Device/PC] Everything runs normal until yon knock (or should it be spelled NOC ;-) ) Balun2 off the wall. At this point, the IDC (or UDC if you're from IBM) shorts the transmit and receive pairs together. The network all of a sudden comes to its knees. Why? BPDUs go out the Balun interface saying they have MAC addresses off other ports. When the packets hit the wire where Balun2 use to be, it returns back to the switch, making the switch think all the MAC addresses have moved to that port. Now the switch is confused and tries figuring out where everything is but the process continues. This actually happened to me as we converted a network from Token Ring to Ethernet. It was cheaper for us to purchase a bunch of baluns compared to pulling new wire (we wanted to pull new wire but the money wasn't there). Way too much fun. Ken Note: Some people call them a balun and others a balum. I don't care. You decide. :-) >>> "Ken Chipps" 09/22/02 01:28PM >>> As I recall from the old days of using Token Ring there was some reason you could not just make these. You have to buy them already made. Something to do with the circuitry. I can look in my Token Ring stuff, after I blow off the dust, if anyone really wants to know. Assuming I am remembering this right.

For many purposes there's not much for the network
administrator to do, as you mention. In other contexts
such as a company that has a bunch of expensive PBXs that
have to be integrated onto the WAN portion of the data
network, one must exercise care to benefit from bypassing
PSTN and other legacy solutions.
Later steps can be taken to evolve to the full AVVID
solution discussed in the CIPT book, but for now I have to
focus on the Cvoice model, namely, using VoFR, VoATM and
VoIP to stop the hemorrhage of funds into legacy
long-distance voice networking. Getting those PBXs talking
to each other over an FR or ATM cloud is no small matter,
and the economic benefit is huge.

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.

Re: Which Version of ATM to Use [7:53737]
I have binded PVCs to Vlans. It worked well for years. Last month, to my surprise, one PVC went down and I lost the Vlans binded, but the Vlans with LANE 'rerouted' to other available PVC. It do not means LANE is better than bind Vlans, because there were other problems related with LANE. One big advantage of Bind is QoS.

RE: ISDN oddities [7:53897]
Hi Jenny To clear an ISDN B Channel requires two steps 1) To figure out which serial interface it is eg serial 1/0:12 2) Issue the command to clear the required interface: clear int serial 1/0:12 That will reset the ISDN-B Channel If the dialup was via Async, you would enter: clear line tty x Well that's what I do, maybe somebody else has better ideas! Manish -Original Message- From: Jenny McLeod [mailto:[EMAIL PROTECTED]] Sent: 23 September 2002 09:07 To: [EMAIL PROTECTED] Subject: ISDN oddities [7:53897] I'm having a problem with some ISDN channels. We use ISDN as a failover for other services. The ISDN is on a AS5300 (IOS 12.1) - note that this is ETSI (switch type primary-net5). Lots of dialer interfaces, load thresholds set, ppp multilink used. The AS5300 dials the remote sites. 60 channels available all up, over two router interfaces, and up to twenty at each remote end (7500s), but max-link is set lower so that if we lose a lot of sites at once they can all get a look in (we then fiddle manually to allow more channels if necessary). Today, a hub frame relay service went plunk, throwing a stack of offices onto the ISDN. No great problem there. Except that, after a while, the AS5300 decided that it didn't really feel like raising any more calls. Most channels on s1:15 were in use, and some on s0:15 - the others appeared to be usable, but the router wasn't raising calls although loads were above the thresholds. Interestingly, when one channel was dropped (due to load decreasing), it was immediately used by a different (still busy) site. Also, the AS5300 was repeatedly attempting to call one office, but the call was being dropped almost immediately. Some debugging showed that ppp authentication was succeeding but the call was being dropped - by the called end - immediately after authentication anyway. This office already had several other successful calls in place, but it wasn't at its max-call limit. I couldn't do a lot of active troubleshooting (e.g. shut/no shutting the ISDN interface) as I didn't want to jeopardise the connectivity that was in place. Any suggestions as to what to look for/try if this happens again? Is there any way of clearing a single B channel?

RE: MCNS Exam [7:53894]
The new MCNS exam is supposed to replace the current exam in October 2002 (probably in about a week or so) with new features. When the MCNS beta exam was available, Cisco made this announcement: "The MCNS 641-100 BETA exam is the final step in preparation for the October 2002 launch of the revised MCNS exam. It focuses on the new material included in the new MCNS 3.0 course releasing August 2002. The MCNS 3.0 course fully replaces the existing MCNS 2.0 course. Content covering the PIX Firewall has been removed and several new IOS Firewall and IPSec features have been added. In addition to these new chapters and labs, all content focuses on the IOS software version 12.2.8T, CS ACS 3.0 for Windows 2000 Server, as well as the new Cisco Unified 3.0 IPSec Client."

Re: URGENT: problem with load balancing accross two internet [7:53901]
If you don't want to (or can't) use CEF, just use the command : no ip
route-cache on destination interfaces to desactivate FAST SWITCHING.
NB : using CEF is more efficient than using PROCESS SWITCHING.

Default load balancing is per destination, so if you are testing from a
single workstation you will always hit the same link. To get a more even
load sharing you'll want to enable per packet load sharing. To do this
globally enable CEF ("ip cef" in global config mode), and then add the
following command to the interface config on the interfaces connecting to
the ISPs: "ip load-sharing per-packet".
Hope this helps.

URGENT: problem with load balancing accross two internet links [7:53899]
I have got two internet links from two ISPs boths of which are directly connected to the lan . I would like to set the default gateway of my clients to the 3660 router I have on my network so that it will load balance the outgoing traffic accross the two seperate internet links. I though maybe two equal cost default routes would result in load balancing between equal cost paths . but it didn't work. Is there a command to allow load-balancing between equal cost static routes , that I am missing ? Policy routing is not quite what I want because the load will not be quite balanced. Any clues ?

Pix performance woes [7:53898]
Hi All, I have a question regarding PIX perfromance. and wanted to see what the experienced PIX crowd here has seen before. I am migrating from two seperate Checkpoint 4.1 boxes running on PC's (PIII 733) to one failover 515e bundle. The 515e has a PII 433 cpu in it. The environment is an online trading shop, where there are 4 trading servers. I changed over on the weekend to the PIX solution, tested everything 3 times, and everything was fine. As soon as users hit the most popular server on MOnday morning (250 remote users through the web, connecting to some custom TCP ports) the response time turned to mud and I had to back out to the Checkpoint solution. Unfortunately, because this company loses so much money when the servers are not online, I had no time to gather any stats (memory usage, cpu usage etc). Does anyone know of the maximum number of xlates a 515e can handle? Any insights, web links etc greatly appreciated.
