Help Identifying a PIX

[Darren Ward]

Hi All,

If you can't see the PIX but have access how can you identify exactly
the real model number?

A show version on this one displays:
Hardware: VS440LX, 16MB RAM, CPU Pentium Pro 150MHz

I think it's a PIX 1 but I need to confirm for a DRAM Upgrade to
support PIX v5 Software

Last Question: Anyone know how to retrive the activation key from a PIX?

You answered your own question. Sessions are distinguishable from each 
other because they have different source ports. 80 is a well-known port 
that clients use to get to Web servers. The client uses what is known as an 
ephemeral port -- a port number that the software makes up for the current 
session. It is a high number that won't conflict with a well-known port.

Cisco Access Pro

[Jojo]

I just passed my CCNA and I'm planning to take 
up some more exams.  The thing is  haven't had in my life configured a 
real Cisco router.  I only used RouterSim  for my  
training.  So now, i plan to buy  Cisco Access Pro (AP-EC and 
AP-RC)  as a start in building my mini  lab.
 Is USD 375 a fair price for each?  If 
not, where can I buy them for real cheap? Any suggestions and help will be much 
appreciated. 
Cheers!

New CCNP

[Jay Hennigan]

Took and passed Support 2.0 (919) and Foundation 2.0 (898, 925, 900) today.  
Foundation is grueling because of the length.  Interestingly, I did better
on the Switching part than on Routing or Remote Access, yet I work daily 
with routers and remote access devices and have never configured a set-based
switch in a working environment, just a few practice labs.  I suspect this is
because I studied harder for the part I was least familiar with.  

The tests stuck to the outlined objectives.  A few tricky questions.  Take
the time to read everything very carefully and rule out the wrong answers
until what's left has to be right, even if that's not how you would normally 
express the answer.  I had ample time and finished early.  

I used the Exam Cram for Switching and Support, Paquet's BCRAN book (with a 
name like that, she can't miss) and the Cisco Press ACRC text plus on-the-
job experience, in addition to much time reading the archives of this list.
I also took the online Colt exams from the CCO site, and found them to be 
substantially more difficult than the real thing.  If you do well there,
you're ready.

If you go the Foundation route, you still have to get a passing score on 
each section but the time to take the test is lumped so you may be able 
to allocate more time to those parts where you're weaker.  Pass all sections
and you're $100 ahead.  Fail one and you're out $200.  No stopping the clock
for bio breaks, so ease up on the morning coffee!

Nothing like spending the day in a small room in the back of an airport.

The closest "block" would be to negate my access list below, but this 
list is what we have used to at least get an idea of the level of 
Napster use.  My comments thrown in:

Extended IP access list ingress-filter (well, a piece of it)
! real-time streaming protocol
permit tcp any eq 554 any (1313 matches)
! default Scour port if I recall correctly
permit tcp any eq 1863 any (1591 matches)
! to signon to the Napster service defaults to port 8875; usually 
! just one or a few packets to establish a signon and get an index
! server
permit tcp any eq 8875 any log-input (222 matches)
! Index servers typically on ////
permit tcp any eq  any (10200 matches)
permit tcp any eq  any (6719 matches)
permit tcp any eq  any (4 matches)
! Default Gnutella port
permit tcp any eq 6346 any
permit tcp any any eq 6346
! More Napster index ports
permit tcp any eq  any
permit tcp any eq  any (7 matches)
! Typical range of Napster file transfers
permit tcp any range 6680 6699 any (4800 matches)
permit tcp any any range 6680 6699

Now that fall semester is back in full swing, we had a big increase 
in file sharing traffic, so we are playing with 'traffic-shape group'
command to try and limit their bandwidth.  I'd be interested in the 
configs if anyone else is doing this (or similar) to throttle traffic.

Re: ccie written

[Richard A. Holland]

Unfortunately,  SNA traffic is not going anywhere.  SNA isn't exactly a bad
thing.  The general thinking of most companies is to, rather than drop the
protocol and hardware, use technologies such as DLSw+ and the such to keep
supporting SNA.  Do a lot of work in the field, and you're bound to run into
a few situations where you have to deal with SNA, NetBIOS, etc.  At this
point, you'll thank Cisco for making you learn it.

Somebody did mention the silliness of making us learn how to deal with RIF's
by hand.. and I agree.  But hey, once you earn your CCIE, you'll look back
and be a pretty happy person.

Sorry, I meant to say switch, wrote this too early in the morning
evidently.  So you are saying that STP does not only negotiate at switch
startup, it will constantly detect new loops that are added?  If so,
another question would be whether I could guarentee that it would be this
switch's port that would block to prevent the loop.  Or would it just be
the first switch that detects the problem?

The network looks like this:

    
   | Switch A |-| Switch B |
    
||
| <-- This is link I plugin.
    
   | Switch C |-| Switch D |
    

So if switch D is then plugged in, will it start STP negotiation on the
port even though the switch has already booted?  Or will one of the
switches randomly discover the loop after the link is already forwarding
traffic and disable it's interfaces?

Re: AllBooks4Less

[Trace Carpenter]

I should have mentioned in my last post, be careful.  A few of the books I found
at this site were the ones for the previous cicso exams, (1.0 instead of 2.0).
For instance for CCNA they were the books by the same name as the current book,
but for exam 640-407 instead of 640-507.  Check the copyright dates.  If you
find one here you need, you will save money.

The D channel is only for communication between your ISDN equipment 
and your LEC switch, and doesn't enter into the picture on the long
distance portion of the call.  

The two B channels are considered separate calls as far as the carrier 
is concerned. 

In these days, virtually all LD telephone circuits are a 56K or 64K
digital bitstream.  There may be some long-distance circuits that can't 
hand a 64K clear channel, in which case you'll get a 56K throughput per
channel.

Re: Could someone help me !

[AUX0]

You generally do not specifiy the source port on your machine. TCP/IP or the
apllication decides. When you connect to port 80 on the webserver it sees
your IP Address and the source port you came in on to communicate back to
your IP Address and that port. That is why you can opn many instances of
your web browser and go to different websites. Each instance is going to use
a different source port to connect to the webserver and each webserver is
going to use the source port you browser app picked to communicate back to
that browser.

I hope that helped and di not confuse it more.

ISDN question

[Quadri, Habeeb]

Hello,

I have a scenario that needs explanation from somebody who knows how ISDN
switches work in carrier enviornment.
Lets say, I am connected to ISDN provided by LEC (GTE) in Dallas that needs
to be connected to a ISDN provided by Ameritech in Indy.
Here is the question,  How long distance carrier like AT&T or Sprint or
1010288 will know that this is ISDN digital signal with 2B+D channels.


Thanks.

Could someone help me !

[RAUNIYAR RAJEEV]

Hi all,

now i DO have a question. i'm reading up about ports used by TCP/UDP
protocols but im having trouble visualizing where the source port and
destination ports fit in. im thinking that the destination port (suppose
on a www, http segment) of 80, would be on the server from which we will
download the data right? and we would specify a port (called source
port) to which we want the data to come into our machine right?
but then how would the www server distinguish between many sessions if
their port is always port 80??

another example... suppose a college closes a "napster" port... can't you
just log onto the napster server using a different port from your
college? hmm.. i really confused.

could you somehow help me visualize where these ports are in the
network. and who sets them and how destination servers and clients differ
etc..

thanks,

RE: Napster Question

[Trevor Corness, CCNA]

The list went through this several times already.

Blocking ports , , ,  is useless.. since Beta6, Napster has
been able to work on ANY port, INCLUDING 80.. so to kill Napster, you would
have to kill all access to http/tcp80.. NOT good.  Blocking the IPs is the
best and most thorough solution at this time.

Also, besides blocking the access to the main Napster sites will block most
users, and for those that go around it, there should be a user policy in
place.  It is not totally your job to govern what the users do and do not
do.. the users should also be held responsible.  Put a political policy in
place, and if it is broken by a user by using something such as opennap,
discipline from management will solve this issue.

Blocking these IP addresses will only block users from accessing the main
napster servers and will not block access to other napster servers, such as,
opennap, which can be found easily by using the napigator program.  The best
way to block Napster is to block the ports that the client uses which are

documentation at the moment, but I think they are right.

Re: Explanation for VLSM

It's a very well-known article by Chuck Semeria. He was at 3Com when he 
wrote it. I'm sure 3Com has the copyright.

No telling why NetGate has it at their site too without crediting Chuck for 
his terrific work. Their Frame Relay tutorial is from a different site too.

Re: Router / Switch Simulation for BCMSN (Switching Exam)

[Thomas Lisa]

We are using RouterSim Ver 2 in our Academy.  So far, it seems adequate
for CCNA level study, with various types of routers & switches.  There are
a number of things we would like improved/changed, but isn't that the case
with every software product?  I don't know if it would work for CCNP level
study though.

RE: Napster Question

[Hal White]

I found my documentation and of course my memory had failed me.  The ports 
for napster are ,6699,,9009.  I think blocking these will disable 
napster.

RE: Napster Question

[Hal White]

Blocking these IP addresses will only block users from accessing the main 
napster servers and will not block access to other napster servers, such as, 
opennap, which can be found easily by using the napigator program.  The best 
way to block Napster is to block the ports that the client uses which are 
,,,.  Don't quote me on these ports because I can't find my 
documentation at the moment, but I think they are right.

Re: Juniper

[Erick B.]

I would determine what your goal is first, then find
the best product for that piece of the network. Now,
best product to many means many things. I'm not into
sales and I don't care who makes the box. I look at
features/performance/interoperability/vendor support
capability/good box for the buck, etc. However, If it
were a box coming out of the kid's garage down the
street I'd be more cautious then a established
company. 
Juniper is also good with following the standards
(RFCs, etc) and has some very sharp people working for
them. 

If your using standard protocols end-to-end then you
should be able to use pretty much any vendors box, but
if your using propiertary protocols (or extensions)
then you have little or no choice on what to use. This
may be a problem in the future when you can't find a
product that supports this protocol, etc and have to
re-design to get around the problem. 

Just my 2 cents...

Which freeware/shareware TACAC+ server do you recommend? Do they support

According to CCIE Fundamentals: Network Design and Case Studies, there

RE: LAYER 3 SWITCHING

[Roger Wang]

Cisco's "layer 3 switching", simply put, refers to all routing processes
except process switching (conventional routing with CPU).  Namely, any
routing process without CPU's intervention is considered "layer 3
switching".  This has nothing to do with frames (layer 2) obviously.

Re: SMTP troubleshooting

[Casey Fahey]

What kind of mail server?  I would tend to look there first.  For example MS 
Exchange Server can use policies to limit outgoing attachment size.

If the mail server checks out OK, I would take a look at traces of what 
happens when the session times out and see if there is a 'smoking gun', and 
if the session is even hitting the wire.

I would check to see if there is a problem sending ftp files over 1 mb to 
eliminate the network devices, but experience points at the application, not 
the router.

HTH,

Casey

RE: SMTP troubleshooting

[Stull, Cory]

First thing I would do is try to narrow down and figure out if it is
actually an smtp over frame-relay type problem.  Try downloading larger
files over the links in both directions using FTP or just regular file
copying in Microsoft networking...  If it shows the same symptoms as the
mail traffic then you can somewhate rule out it being a problem with your
email servers...If it doesn't show the same symptoms than you've at
least narrowed it down and verified that it probably is a problem with
either the mail servers or the smtp type traffic.   After that, good luck...

Hey all,

Am studying CIT related material and am wondering what one would look for
when troubleshooting SMTP data transfer over an FR circuit, say at 128K
CIR, 256 port speed.

Situation:

Corporate site has 3600 class router with a serial interface configured
with T1 port speed and only 256K CIR. One remote site of 11 has 2500 class
router configured with 256K port speed/128K CIR.  SMTP servers exist at
both sites.  SMTP server at remote does not receive Internet e-mail, it
relies on corporate site SMTP server to supply Internet and corporate wide
mail.

Problem:

Clients at remote site cannot send mail with attachments larger than 1 MB
without 'timing out'.  They can, however, receive mail with large
attachments from the Internet and corporate.  Remote FR circuit tests clean
with no FECN or BECNs to report.

Any suggestions on approaches to this problem?  Need more info?

Re: My impressions of Juniper from the test lab

[Erick B.]

I've been watching them for awhile now and have been
to their new HQ. The M40 can do OC-48 at wire-speed
and the m160 can do OC-192 at wire-speed. You can read
about all the features, ASICs, etc on their website. I
haven't had much opportunitys to get my hands on JunOS
however, anyone willing to donate a M20 to my home
lab? :) You can read the older JunOS Docs on their
website as well, need contract for current release.
It's even available in Palm format which is cool.

Re: SMTP troubleshooting

[Gareth Hinton]

May not be connected with your problem, but are there any firewall's in
between, PIX in particular. If so continue otherwise I'm barking up wrong
tree.
We've had some problems with the fixup protocol smtp 25 command which
activates mailguard and allows only a subset of the smtp command suite. This
caused, for us, exactly this problem of stopping large e-mail attachments.

If anyone has any suggestions for rectifying this other than no fixup smtp
25 I would be interested to hear.

Gareth

Re: Cisco and NT

[Frank Wells]

Sounds like you need to enable a routing protocol or configure static routes 
from each router to the other router.  The ICMP replies need to have a route 
back to their sources for you to see them.

RE: Napster Question

[Fowler, Joey]

Title: RE: Napster Question





If you search the archives it has some info on this, but I just implemented it this morning and it seems to working here. If you are using PIX firewall (or any other) create an access list using the outbound and apply commands to block the following addresses:

208.184.216.0 /24
208.178.167.0 /24 
208.178.163.61
208.184.175.130
208.184.175.131 
208.184.175.132 
208.184.175.134 
208.49.239.242
208.49.239.247 
208.49.239.248


People will start wandering by your desk asking if you've ever heard a program called Napster. I personally like to dumb.

I think that this is the layout that you are describing, and most
likely it is a problem with the gateway of the hosts on the 10.x.x.x
network.  I would set the gateway to the Cisco Router, and then
make sure that the cisco router had a route back to the 100.x.x.x
network through the NT4 Box.

Hello, everybody,

This is my first post.  I have a simple question.
I'm trying to use dual-homed NT4 as a router on a network that already has
2 Cisco routers.  The Cisco routers are on the B NIC side of NT, while other
NT
hosts are on the A NIC side of NT.  Hosts on A side can ping the B NIC, but
no
other hosts on the B NIC side.  IP forwarding is turned on. When I create a
separate network without the Cisco routers, and just 2 NT4 routers, theres
no
problem, but when connected to the Cisco router network, everything changes.
Are there any issues in advertising between the Cisco routers and NT?

My impressions of Juniper from the test lab

[David Wolsefer]

The juniper M20,M40, and M160 are serious routers in the core IP routing
world because they simply outperform the 12000GSR. Although I did not test
them against the latest and greatest GSR, we ran tests with the M40 heads up
against a few older model GSRs. Needless to say, the Juniper is very
impressive. We took a smartbits and started loading up the links up to
OC-48. The M40 handled the load extremely well at wire speed with no packet
loss. The GSR, on the other hand, started dropping packets at about 50% of
that load. Does this mean the performance couldn't be improved on the GSR?
No, not at all. These GSRs were not tuned at all. They were straight out of
the box (so to speak). I think that the bottom line is that we, as
engineers, need to be prepared to work with both products. I like Junos and
love IOS. You will not get fired for recommending either product. I believe
that pricing is competitive for both products as well.

RE: ccie written

Either that post is flamebait or someone is having a hearty laugh at some of 
the other posts we sometimes get like this.  (uh I don't know where a router 
power button is/what a packet is/how to plug in an RJ-45 cable - by John

Generally speaking, I'd say if you're CCNP/CCDP/Bay Router Specialist/Red

you have good memory retention from your Cisco exams - but you've got to 
pass the lab in a year or your money's wasted.

And that's the finish line - just passing the written doesn't cut it, doc.

The one thing that helped me through this exam was to download from Cisco
the specification sheets that have the nice diagrams showing the front and
back of the gear.
 
These visual representations gave me the ability to answer some of the
configuration questions about the different units. I am a visual hands on
person so your mileage might vary.

This exam is sitting on my head and crushing it.  *So* many different
switches to remember, all their cards that they do or do not support (and in
which slots), how large their CAM tables are, how many ports, which user
interface comes with which version of software...yadda yadda yadda.
 
So, instead of asking "is all of this really on the test?" like some wannabe
paper chaser, I'll ask a slightly more creative question: has anyone come up
with any mnemonic devices which might help one memorize all of these
minutiae?

Re: Juniper

[Patrick A. Morin]

First of all, Juniper has an oc-192 interface that actually does oc-192 and
that will still do oc-192 with an access-list on it. Cisco doesn't have a true
oc-192 card yet. They have OC-192 optics with an engine 3 forwarding engine
so it can do about 2.5Gbps, that's before applying access-lists... 

I have a couple of GSRs here and there single OC-12 can barely forward more
than an OC-3 if you start putting access-lists and CARs on it. Not so with
the Junipers. (I know a quad OC-12 with engine 2 works better BTW)

So, Juniper very very fast, GSRs fast.

On the GSR, the processing is offloaded to the cards, but it's still done in 
software on the cards. On Junipers, the processing is offloaded to the cards,
but it's done in hardware on specialize ASICs.

Re: Gig fiber questions

[Don Hickey]

Ben,

Not sure about the Cisco to HP compatability issue, But you are pretty
correct on the Mode-Conditioning fiber.

They offset the singlemode fiber from the center of the multimode fiber to
transmit the signal. Remember you will need a mode-conditioning fiber patch
cord on each end. Also you need to switch the Receive and Transmit at the
fiber patch panel and not the GBIC. This one has got me a few times.

Subject: Problem after 2501 to 2503


Hi all,
  I have a 2501 router connecting to my ISP.Last week I changed it to
2503
with the same config and although it is working fine with backup,for the
last
2 to 3 days,my site people are not able to browse the internet as fast as
they
used to do when the 2501 was present .I have a 64Kbps link to the ISP.Upon
checking with my ISP,he asked me to increase my bandwidth,but my utilization
even during peak hours is about 80% by taking the avg.of the 5 minute I/p
and
O/p rate.
  Also the number of users are literally the same.
   Then why the browsing is slow.I swapped back to 2501 for an hour or
so
and the browsing was better?Can anyone tell me why is it happening?

Thanks&Regards,
Sakar

Cisco and NT

[NetCom]

Hello, everybody,
 
This is my first post.  I have a simple 
question.
I'm trying to use dual-homed NT4 as a router on a network that 
already has
2 Cisco routers.  The Cisco routers are on the B NIC side 
of NT, while other NT
hosts are on the A NIC side of NT.  Hosts on A side can 
ping the B NIC, but no
other hosts on the B NIC side.  IP forwarding is turned 
on. When I create a
separate network without the Cisco routers, and just 2 NT4 
routers, theres no
problem, but when connected to the Cisco router network, 
everything changes.
Are there any issues in advertising between the Cisco routers 
and NT?

Phillip,

With the exception of some 25xx's at work I really have nothing at home.
But at work I have everything from 2503's to Cat65k's running 802.1q.  I
have extensive hands on with 2500/2600/3600/7200/7500 routers, and
practically every switch that Cisco makes.  Although, I have no PIX
experience whatsoever.  We use a product by Checkpoint called Firewall01.

Thanks.

Cisco bought a company called Cerent several months back. I was given a tour
of a Nextlink ( now X0, after their purchase of Concentric ) pop recently.
Full of Cerent stuff, and the engineer there waxed on and on about how great
it was. All fiber connections. Carrier class. If memory servers, these
suckers weren't more than 12 inches high?  So Cisco isn't standing still in
this market space.  Can't find much on the Cisco site about the product
line.

Absolutely.  The Juniper M20, M40, and M160 Internet Backbone Routers
are sometimes chosen instead of the Cisco 12000 Series.  Press reports
say that Juniper has gained some of the market share at Cisco's expense
in this area.  They have just released the smaller M5 and M10.

No doubt Cisco are well aware, and even as we speak steps are being
taken to ensure that Cisco regain their lost ground and reaffirm
themselves as Masters of the Universe ;-)

Hi all,

Which freeware/shareware TACAC+ server do you recommend? Do they support
date/time authentication? i.e: USERA can login on Monday but not Tuesday?

According to CCIE Fundamentals: Network Design and Case Studies, there
should be a free copy of TACAC+ for Unix at ftp.cisco.com/pub but I cannot
locate it.

Does STP only stop loops when the router boots?  If I am building a loop
network, and then I boot up the final router with only one interface
plugged in (so it is not yet a loop), and then plug in the other interface
after the fact, what will happen?  Will the other interface start in
blocking or forwarding mode?  The book I am using does not seem clear on
this.

RE: STP question

[Chuck Larrieu]

Check your spelling. I think you mean Le Mans, not lamens. The port goes
into racing mode, trying to beat the course time for creating a new tree,
without wrapping itself around one. I still like those Ferrari's the best

When you plug in your other port the port will go into listening, learning
states.  In lamens terms the port sends out a frame and if it hears it back
it will block - if it doesnt it will forward.  Please see link below:-

Does STP only stop loops when the router boots?  If I am building a loop
network, and then I boot up the final router with only one interface
plugged in (so it is not yet a loop), and then plug in the other interface
after the fact, what will happen?  Will the other interface start in
blocking or forwarding mode?  The book I am using does not seem clear on
this.

Sorry, I meant to say switch, wrote this too early in the morning
evidently.  So you are saying that STP does not only negotiate at switch
startup, it will constantly detect new loops that are added?  If so,
another question would be whether I could guarentee that it would be this
switch's port that would block to prevent the loop.  Or would it just be
the first switch that detects the problem?

The network looks like this:

    
   | Switch A |-| Switch B |
    
||
| <-- This is link I plugin.
    
   | Switch C |-| Switch D |
    

So if switch D is then plugged in, will it start STP negotiation on the
port even though the switch has already booted?  Or will one of the
switches randomly discover the loop after the link is already forwarding
traffic and disable it's interfaces?

Re: STP question

[Bradley J. Wilson]

>From your diagram here, it looks like you don't have a loop - it looks like
Sw B is plugged into Sw A, A to C, then C to D in series.  If this is
accurate, then you don't have a loop and won't have any problems.

As far as STP works, each switch will send out BPDUs every two seconds on
all interfaces.  If a switch receives two BPDUs from the same switch on two
different interfaces, it will start the election process and you'll have a
few seconds of downtime (not exactly sure how much - 15 or so?).  But again,
from this diagram it doesn't look like you have a loop, so you should be
okay.

Re: CCIEBootCamp Labs

[Circusnuts]

I believe you're right Dale.  I've a friend who took the CCIE lab twice this
year.  He said 9 & 10 (the last two in the current CCIE bootcamp manual) are
harder than the lab itself.  What flustered him (on the first attempt) was
the equipment (specifically the patch panel setup on the rack), & he took
too long drawing out the network scenario.  I'm not sure what version
manuals are out currently (mine is a year old), & I know they've added voice
& IPSec (encryption) to the labs.  Also- in the CCIE lab you'll work with
11.2(18), 11.3, & 12.0 IOS, & must know the defaults (& interworking
characteristics of each)...

My take on the lab in a nutshell :-)

Re: trace route results

[Ejay Hire]

The ICMP echo packets are (hopefully) traversing the same path at slightly 
different times.  If the load on a segment varies, then the amount of time 
that segment delays the packet will also vary.

Use driving as an example:

If it weree a perfect world,
I drive From point a to point B it takes 5 minutes.
I drive From point a to point B to point C it takes 10 minutes.

But it's not a perfect world, and I get stuck behind some little old 
Gray-haired Lady in a 1972 Impala (Big Car <-> Big Packets) driving 45 in a 
70, then it's going to take longer to get from point A to Point B.
Thusly, even though only on part of my trip was slower than normal, the 
entire round trip is affected.

Hope This helps,

RE: Juniper

[Chuck Larrieu]

Cisco bought a company called Cerent several months back. I was given a tour
of a Nextlink ( now X0, after their purchase of Concentric ) pop recently.
Full of Cerent stuff, and the engineer there waxed on and on about how great
it was. All fiber connections. Carrier class. If memory servers, these
suckers weren't more than 12 inches high?  So Cisco isn't standing still in
this market space.  Can't find much on the Cisco site about the product
line.

Absolutely.  The Juniper M20, M40, and M160 Internet Backbone Routers

say that Juniper has gained some of the market share at Cisco's expense
in this area.  They have just released the smaller M5 and M10.

No doubt Cisco are well aware, and even as we speak steps are being

Switching, 640-504

[Bradley J. Wilson]

This exam is sitting on my head and crushing 
it.  *So* many different switches to remember, all their cards that they do 
or do not support (and in which slots), how large their CAM tables are, how many 
ports, which user interface comes with which version of software...yadda yadda 
yadda.
 
So, instead of asking "is all of this really on the 
test?" like some wannabe paper chaser, I'll ask a slightly more creative 
question: has anyone come up with any mnemonic devices which might help one 
memorize all of these minutiae?
 
Thanks in advance -

Re: Juniper

So why is Juniper better than cisco 12000? I think because it is faster, but
anybody knows why?
I think the basic technology Juniper is using should not have  too many
difference compared with Cisco, MPLS, ASIC, etc.., so why they can be faster
and better? does it because their software is better or something else? if
anybody knows some comparision reports  that will be great.

  I ordered an IDSL line for my house and the ISP tells me that

  quietly remove the bridge and replace it with, say, a Cisco 804?  I sure 
  would like to use the 804, but since one of the interfaces is IDSL, I can't

RE: STP question

[McCallum, Robert]

When you plug in your other port the port will go into listening, learning
states.  In lamens terms the port sends out a frame and if it hears it back
it will block - if it doesnt it will forward.  Please see link below:-

Does STP only stop loops when the router boots?  If I am building a loop
network, and then I boot up the final router with only one interface
plugged in (so it is not yet a loop), and then plug in the other interface
after the fact, what will happen?  Will the other interface start in
blocking or forwarding mode?  The book I am using does not seem clear on
this.

Re: PRI vs T1

[Ben Groff]

Well...  In North America a PRI is a T-1, but a T-1 is not necessarily a
PRI.  The T-1 will provide 1.536 Mbps in usable bandwidth, assuming it
is using B8ZS linecoding...  The PRI will offer 1.472 if it is
configured as 23B+D (and the underlying T-1 is B8ZS)...  Hope this helps
some.

RE: isdn

Hi there,

ftp://ftp.sybex.com/2381/CCNA_c11.pdf

If you read this updated chapter 11 about WAN, you can read the following on
page 18:

NT1 implements the physical layer specifications and connects the user
devices to the ISDN network.

NT2 is typically a provider's equipment, such as a switch or PBX. It also
provides Data Link and Network layer implementation. It's very rare at a

Re: STP question

[Bradley J. Wilson]

Spanning Tree Protocol, which I'm assuming is what you're referring to,
doesn't have anything to do with routing.  If you were connecting bridges
together in a loop, STP would break the loop and you'd be fine.  In your
case, the mechanism which will prevent routing loops is split horizon
(assuming you're running RIP), which is on by default.

Hope this helps -

SMTP troubleshooting

[Raul_DeLaGarza]

Hey all,

Am studying CIT related material and am wondering what one would look for
when troubleshooting SMTP data transfer over an FR circuit, say at 128K
CIR, 256 port speed.

Situation:

Corporate site has 3600 class router with a serial interface configured
with T1 port speed and only 256K CIR. One remote site of 11 has 2500 class
router configured with 256K port speed/128K CIR.  SMTP servers exist at
both sites.  SMTP server at remote does not receive Internet e-mail, it
relies on corporate site SMTP server to supply Internet and corporate wide
mail.

Problem:

Clients at remote site cannot send mail with attachments larger than 1 MB
without 'timing out'.  They can, however, receive mail with large
attachments from the Internet and corporate.  Remote FR circuit tests clean
with no FECN or BECNs to report.

Any suggestions on approaches to this problem?  Need more info?

They are not really one and the same.  That is to say, if you have a T1 do
you have a PRI?  Maybe, but not necessarily.  If you have a PRI do you
have a T1?  Yes (imho) because you have a DS1 data rate riding over
copper.

Re: PRI vs T1

[Lowell Sharrah]

outstanding!!

>>> "michael champion" <[EMAIL PROTECTED]> 09/28/00 02:45PM >>>
A T1 frame is 193 bits. 192 bits (24X8) corresponds to data, and 1 bit is
used for synchronization. There are 8000 frames per second. T1 was
originally defined for PCM-encoded voice (8 bits per channel, but 1 bit for
signaling when needed - "robbed-bit signaling"), with 24 voice channels per
frame. It is actually unfortunate that "T-1" became a generic term for
anything that has a 1.544 Mbs bit-rate, because T1, DS1, and ISDN PRI should
be defined completely differently. T1 should have been reserved for
24-channel voice, DS1 for 24-channel data, and PRI for 23-channel
+1D-channel (ISDN).

Regardless T1 frame= 24(8-bit voice + signaling) channels + 1sync bit
  DS1 frame = 24(8-bit digital data)  + 1 sync bit
  ISDN frame = 23(8-bit digital data) + 1(8-bit signaling) +
1 sync-bit(as logically represented on a T1 carrier)

Therefore, 193X8000  = 1544000 clock-rate for T1 (DS1).
 192X8000  = 1536000 data-bits/sec for T1 (DS1).
 1X8000  =  8000 sync-bits/sec for T1 (DS1).

Notice that there is no defined signaling channel. If multiple sites are
sharing a T1(DS1) link then without some form of common signaling there
would have to be in-band signaling, which would reduce the 8-bits per
channel to 7-bits per channel (ever heard of "switched-56K"?). Fractional T1
would allow common signaling for a higher user data-rate.

Therefore, assuming that some form of out-of-band signaling exists, T1(DS1)
provides 1.536 Mbs of bandwidth, with 8Kbs lost due to sync bits.

The question for PRI becomes even more confused. 23 B-channels + 1 D-channel
+ 1 sync-bit, but the D-channel is primarily used for common signaling. The
question is if there are 23 B-channels at 64Kbs each, how much of the
D-channel's bandwidth can be used for user data, if any (for example, by
running X25 on top of the signaling channel)? This would imply that PRI
would have only 23X64Kbs for user data plus 64Kbs for signaling. Although
ISDN is considered to be all digital, in reality PCM-encoded voice on a T1
line is a digital representation of an analog sample. ISDN still uses T1,
T3, etc. lines to bundle multiple facilities on a common line, but the
channels are interpreted differently. What is really fascinating is to see
how ISDN achieves these rates via the data format from the U-interface.

So the question is "which provides 1.544 Mbs of bandwidth, T1 or PRI?" is
nebulous at best. Neither can provide 1.544 Mbs for exclusive use for user
data. But both have a 1.544 Mbs clock-rate.

Voice/Bri

[Olden Pieterse]

Hi there gang

Does anyone have sample configs or tips on the Voice/Bri for the 2600 & 3600
?
I have some but I need some input on what other people experienced in
similar situations .

Again Cisco's sample configs didn't do the trick .

Thx

RE: Problem after 2501 to 2503

[McCallum, Robert]

a stab in the dark.  Different IOS versions?  Less memory in the router?

Subject: Problem after 2501 to 2503


Hi all,
  I have a 2501 router connecting to my ISP.Last week I changed it to
2503
with the same config and although it is working fine with backup,for the
last
2 to 3 days,my site people are not able to browse the internet as fast as
they
used to do when the 2501 was present .I have a 64Kbps link to the ISP.Upon
checking with my ISP,he asked me to increase my bandwidth,but my utilization
even during peak hours is about 80% by taking the avg.of the 5 minute I/p
and
O/p rate.
  Also the number of users are literally the same.
   Then why the browsing is slow.I swapped back to 2501 for an hour or
so
and the browsing was better?Can anyone tell me why is it happening?

Thanks&Regards,
Sakar

RE: Re[2]: Cisco Documentation CD and Win 2000

[McCallum, Robert]

See if this helps.

To get the Cisco documentation to work under Windows 2000:

- Run regedit

- Locate HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/IE4/Setup/Path

- Change the value from "%programfiles%\Internet Explorer" to the location
where IE is installed on your system, for example "C:\Program Files\Internet
Explorer".

- Install the Documentation CD (I only install the web publisher component
and install the rest from newer versions).

Should be good to go...

Hope this helps.

Well, I just deleted "plugins" directory which is under the Cisco CD
installation dir, and all its subdirs.
I know several people who did it and it works fine!
