Stop records problem in AS5300

[Saeed Siddiqui]

Hi Group,

I am having problem with AS5300 that some stop records are not been sent
from AS5300 to Radius Server. It has been observer the people who are
connected for long time ( 3 hrs +) and not being charged for their usage and
the stop record is missing from the Cisco Secure Radius Server (ver 2.3.3)
log file. As5300 and Radius server are connected to two different security
zones of PIX FW.
I am running 12.07 T IOS on AS5300s.

Any suggestion ??



Thanks

Standard Cisco passwords

[Hans Stout]

Hi colleagues,

do you know what the Cisco standard passwords are ? As far as I remember, 
they are 'cisco' and 'sanfran', but I am not sure (also not sure about 
lower/upper case).
Thanks for your help in advance.

RE: Decnet routing with using HSRP

I haven't heard anything.  As far as I know you still cannot run HSRP on the

Subject: Decnet routing with using HSRP


Hi,

My company is using Cisco 2501 and 2621 routers. We are using DECNET and
TCP/IP protocols. Before that, I know that when the router is enable DECNET
routing, it cannot implement HSRP. However, somebody told me that a new
verison IOS can do that. Is that true? If true, where can I find this
information?

Incredulous! Now CCDA Exam is a CCNP Perequisite?

[rtc]

  I just checked Cisco Site to find that CCDA is a perequisite. Is this for
real? What is the CCDA? When did they sneak that in with the CCNA? Now I
have a total of 5 exams to take?
 Is there a CCDA Book? I have the CCNA. I am flustered; I'm not smart; I'm a
hard worker. But I would like to see the Grand Canyon or ski or just walk
around at the mall sometime in the next 5 years!

RE: cannot see route in bgp table?

[Gils]

Hi,

   Your problem is as follows:
1.First you need to do a different test in order for you to see your own
networks in the BGP table and it goes like that "show ip bgp neighbors
*.*.*.* (peer ip) advertised-routes".
If you still don't see you advertisements add the following statments:
ip route 202.77.96.0 255.255.224.0 null 0, because you are using the network
statments and network statments only advertise the routes that are in the
routing table, so with the route to null you make sure that those networks
are always in the routing table even if those networks are unavailable.

Aux + external ISDN-Modem <-> Bri ?

[Herold Heiko]

Situation: local 3640 with bri ports present.
Remote office, only router currently present: a 2515 used for a 64k
framerelay connection. I need to connect that office to the local one
with a interim solution (waiting for the real frame relay connection,
couple of months unfortunately since it's international ecc), and was
thinking:

external ISDN Modem with serial port - Aux port un 2515
  |
  |
  |
Bri on our 3640

If the external Isdn modem does have a Hayes "AT" command set emulation
I should be able to configure the 2515 just like if te ISDN adapter was
a normal serial modem, right ? And configure a normal dialer on my local
router on a bri port.
BTW OS are 11.2 on both sides.
The connection will be single channel (64k) only.
Any idea what could go wrong, since one router will really work with a
bri port while the other really will be configured for a serial modem ?
There _should_ be at least a speed problem (as to
http://www.cisco.com/warp/customer/76/9.html#port_speed the Aux on 2515
seems to be limited to 38400) but I can live with that. However I'm more
concerned with the serial interrupt problem, should I expect high cpu
problems with a 64k frame relay+38400aux link, I'm expecting nothing
else (no access lists, no route maps, static routing, fast switching
everywhere I think) although I don't have (yet) the exact conf.

If this could work, any experience on particular brands/models of
ISDNmodem to avoid/prefer ?

(I'll keep you informed on success/failure anyway)

Thanks
Heiko

PIX Firewall user connections

[Hans Stout]

Hi colleagues,

I have a question regarding the PIX Firewall: when they mention the number 
of user connections, what does that actually mean ? Does e.g. the 520 model 
allow 250,000+ user to be connected simultaneously ?
Also, the new 506 PIX model does not specify the number of user connections 
allowed, does this mean that there is no limit ?
Thanks for your help in advance.

TCP/ UDP header

[Thomas Peroutka]

Hi Guys,

just reading a book and saw pictures of TCP and UDP headers. Whereas
the UDP header has a length field describing the length of the UDP
segment including data and header, I can´t see such a field in TCP.
Is this an error of the book or how does TCP determine the length of
the segment/ the end of data?

Re: FTP Vs TFTP

[Phil Barker]

FTP bigger executable, more functionality, runs over
TCP therefore reliable, uses ports 20 & 21.

TFTP smaller executable, less functionality, runs over
UDP therefore unreliable delivery, uses port 69.

Phil.

Re: CCNP is easy to achieved now!

[wind]

i just running out of interest to discuss this topic,

i never say i am good in networking,  what i concern is about the
difficulty,
I am not even concern myself is professional or wat.  CCNP exams are
just a foundation networking exam,  maybe you guys thought
it is difficult.

You guys thought of the cert is valuable,  but to me is just a paper.  you
can get the
paper, so what, no big deal.  i just do not understand why you guys so care
about
the 'paper".  Ask yourself what you can do after certify is more important

If you are good at it, why bother, why not go for CCIE.

The point is the exam questions is just based on the study guide, one book
can
pass.   The passing score is definitely lower, no type in, you can guess the
answer,
you know, in the old exam, no study guide. have to search for the cco, ask
you
detailed questions, some questions even ask you the deatil protocol
characteristics,
passing score is just 690 instead of 790. a 100 score minus.

Are you working for coroporate or system integator?  Working for the system
integrator
definitely will find the exam easy.

What i am saying that, the exam lost its value.  As long as more paper
people will
be flooder in the market, we will see.

Studying any technology for this amount of time is

have 3-years material in it to study ?

Is the course full or part time ?

PS:  I realise ATM will be around for a long time, but
I just cannot help disliking it .. Its just a pet

me.

RE: 5-4-3 Rule

[Hitesh Pathak (CSD-BBYRO-RTSG)]

It defines a general networking setup like if u have a single network then
it should have 5 segments , 4 repeaters & out of 5 segments atleast 3 should
be populated ie. on 3 segments you should have some node connected.

group , pls correct me if I'm wrong.

RE: The CCNA 1.0 exam has been retired as of July 31, 2000.

[Paree-huff, Andre]

As of 31-JUL-00 you were no longer able to acqurie the CCNA v1
certification.  As of 01-AUG-00 you were required to take the V2 CCNA test
for certification.  What is so hard to understand about this? The test is
still available, the just changed it at some point they had to retire the
old version and they chose 31-JUL-00 to do so.  At the current time
everything is V2. I assume within the next year we'll start to see V3 exams
being availalbe and those will be what has changed since the V2 was
released.

RE: 5-4-3 Rule

[Paree-huff, Andre]

This rule is really no longer accurate.  To truly find out if your network
is within spec, you need to figure the round trip bit delay per segment and
device.

the 5-4-3 rule is about like the 80/20 rule great for the old days but not
for today.

Re: CCDA Study Materials

[analogkid01]

Hi Len -

I honestly don't know if there are really any texts that adequately prepare one for 
the CCDA exam.  I used the Syngress book myself, and spent hours coming up with all 
sorts of mnemonic devices to help me remember the lists of requirements and procedures 
that I thought were going to be on the exam.  When I finally got into the exam, I felt 
extremely ill-prepared and was very surprised when I found that I had passed it 
(855/1000).

What it boils down to is this: glean whatever you can from whatever book you're using, 
and go ahead and take the test when you're done with your study materials, just be 
prepared for a *lot* of reading comprehension-type questions, and pace yourself 
accordingly.

Best of luck -

Woo hoo! I found one I can answer! Let's see, it's used with Ethernet, in that there can be 5 segments, four repeaters/hubs, but only three can have stations attached. 

If you've studied how routers work, it is not a logical subnet such at one made by IP addresses but a physical subnet. Hope this helps.

RE: Aironet 340 Series

[David Jones]

I have installed a couple of them.  They're pretty easy to setup and get
running.  Just realize, that the max you're going to get is around 6mbps.
Haven't done encryption yet.  I went to a free "training" session with Cisco
and unfortunately, they didn't have the equipment setup ahead of time and
the engineer kept having problems getting encryption working.  It was quite
interesting.  Make sure you get their Excel spreadsheet on calculating
distances and which antennaes you would require, etc.

RE: CCDA Study Materials

[Croyle, James]

I will agree on this point about reading comprehension questions.  I took
all the CCNP courses through www.knowledgenet.com since Cisco Press books
for 2.0 were hard to come by.  After I completed that, I ready Top Down
Network Design  (Thanks Priscilla) and Designing Cisco Networks.  One person
at our company took the CCDA and failed by about 100, but I took is and
passed with around 860 3 weeks ago.  You cannot be too prepared for this
test, thought it is straight forward, it pulled knowledge from each of the
resources I mentioned before.  Also, when you get the case study, draw the
WHOLE thing out, because you will be referring to it about 5 times.  The
other individual at my company got 3 scenarios, and I got 4.  I finished
with plenty of time, maybe 50 minutes left, but only because I drew the
scenarios is complete detail even though the first question was just a basic
"count the equipment question."  

IMHO as always.

Hi Len -

I honestly don't know if there are really any texts that adequately prepare
one for the CCDA exam.  I used the Syngress book myself, and spent hours
coming up with all sorts of mnemonic devices to help me remember the lists
of requirements and procedures that I thought were going to be on the exam.
When I finally got into the exam, I felt extremely ill-prepared and was very
surprised when I found that I had passed it (855/1000).

What it boils down to is this: glean whatever you can from whatever book
you're using, and go ahead and take the test when you're done with your
study materials, just be prepared for a *lot* of reading comprehension-type
questions, and pace yourself accordingly.

Best of luck -

routing and admin distances

[Thomas Peroutka]

Suppose, I configure a static route to a destination with
administrative distance of 110 (sure, I shouldn´t do that, but just

the same destination but another way over OSPF (same admin distance).
Which entry will be in the routing table, which way will be used?

Re: Incredulous! Now CCDA Exam is a CCNP Perequisite?

[David Williams]

Nope, for CCNP you need:
CCNA 1 or 2 (track 1 exam isn't available any more, but if you passed it, it
counts towards CCNA and CCNP)
Routing
Switching
Remote Access, and
Support.
You can combine Routing, Switching and Remote Access into the Foundation
exam, whenever it becomes available.
CCDA is altogether another track (design). You don't need it for CCNP. You
do need it for CCDA and CCDP.

And I hope for the final time, yes, track 1 exams count for CCNP if you took
them on or before 31 July. But any mix of track 1 exams (save the CCNA exam)
will place you in track 1 until you take the requisite track 2 exam.

Officially, you must work for a reseller partner.  It doesn't matter what level, only that your company is an official reseller of Cisco equipment.  If that's the case, then you simply register for the training on the CCO website.  Of course, if you happen to not work for a reseller, then you'll have to be creative when it comes to registering.  I won't tell you how to bypass the rule, but it's not terribly difficult... ;-)

RE: CCNA Advise

[Guyler, Rik [EESUS]]

Title: RE: CCNA Advise





Whoa...8 times?  Really?  That is pretty discouraging...


I have yet to fail a test (13 strong and still going) but I'm not bragging about it, only suggesting that maybe your study habits need a little revision.  I taught IT for a couple of years at a local college and this was the most common problem for students that didn't perform well on the exams.

I have heard Chuck Larrieu, one of the lists' notable members, mention several times that he practices the "vertical" study method.  This entails selecting your topic of choice, say for example the RIP routing protocol, and then study the topic not from a single source, but from several sources.  You could indeed use the Sybex CCNA book, then go to Cisco's site to help fill in the blanks, and then finish up with one of the non-certification routing books, such as Doyles' TCP/IP Routing book.

This is just a sample, but I believe this method to be the most in-depth and comprehensive, which sounds like what you need.  Also, I like to make flash cards on topics that require a fair amount of memorization, such as debug commands, etc.  Remember to spend as much time on a topic as you need, rereading everything until you understand every word in a given paragraph.  Simply reading through without understanding does no good whatsoever.

At this time, might I suggest a break?  Sometimes when I am really trying hard to do something, it just won't work for me.  I take a break, relax and clear my thoughts, and then attack the problem with a renewed vigor.  Sounds lame but it works wonders.

Good luck!

CCNP2.0/CCDP

Title: RE: 5-4-3 Rule



Guys,
 
Today I became a 
CCNP2.0/CCDP.  Thanks for the input provided by all team members.  My 
opinion is that the toughest test was the CID, not because of the material but 
because the ambiguity of the questions.  The test that required the most 
knowledge was the CIT.  The questions are straight forward and you either 
know the answer or not.  I scored the best in the Routing 2.0 but the 
easiest I found was the Switching.

A connection does not equate to a single user.  Actually, a single user can spawn many connections depending on the application he/she is using to cross the firewall.  I have seen Internet Explorer spawn 5 or 6 connections to the Internet for example.  Definitely keep this in mind when ordering your PIX!

Also, the new 506 PIX model does not specify the number of user connections

RE: CCDA Study Materials

[Vijay Ramcharan]

I haven't read that book but I can recommend the CCDA Study Guide from Cisco
Press.  I used that to pass the exam a couple of weeks ago.  Someone
mentioned that they had 4 case studies- if I remember correctly I had 5!
The Study Guide has quite a few case studies- but I didn't go through any of
them and I didn't answer any of the questions at the end of the chapter.
Seriously though, the exam is not that difficult if you have a firm grasp of
the basic issues of networking- Congestion, applications (Web servers, email
servers, NT servers etc.), bandwidth requirements, network topologies,
cabling, etc.  I found the material in the Study Guide more than adequate
for the exam.  Hope this helps.  Oh and by the way, if you ever get down to
studying for the CID exam don't buy the Cisco Internetwork Design guide from
Cisco Press.  I used it to study for the CID exam and was unpleasantly
surprised to find way different material on the exam.  Surprise, surprise- I
failed the exam by a measly few points.  Good luck to you.

Re: load balancing on Rip

[Nurarif Wibawa]

Hi,

I just wondering what the meaning of unequal cost load balancing doesn't
work on RIP.
>From my experience, I have setup a router that has two paths to the same
destination with equal metric (hop count) and also I set different bandwidth
for each path with "bandwidth" command.
When I check it by doing a ping, the packet goes well on both direction.
I think the unequal cost load balancing could not be done by RIP because it
could not arrange the packet so one packet goes to link 1, next two packets
go to link 2, the next one goes to link 1 and so on (for example : link1 ->
512K, link 2 -> 1024K) like EIGRP does. But RIP still load balance the
packet with equal treatment even the bandwidth are different. Since the RIP
header doesn't include any parameter for bandwidth so how it could detect
the bandwidth of link along the path to the destination ?
Please correct me if I'm wrong.

Thank you

Re: Aironet 340 Series

[Collin]

Pete-
I setup a wireless network for our training room 
using 15 laptops and a single 340. I get good throughput in the room (60'X40') 
and bump down to 6Mps about 70' from the training room. It's been flawless so 
far. I had our vendor and SE from Cisco demo the product and we set up a system 
and they let us beat on it. That really helped. I am not running encryption, but 
in the demo we had it running no problem. They only thing I noticed is you need 
to play with the antennas to figure out your best bandwidth. It usually depends 
on where you mount it (wall, table, ceiling, etc.). If you have any other ?'s 
feel free to ask.

permanent ISDN connection

quick question - We're setting up a temp. ISDN connection and the powers 
that be want a PERMANENT (not DDR) connection on a Cisco 2500 (ios 11.2)

I've got a BRI and Dialer setup (which also aren't working, but that's

keep an ISDN connection up in a permanent state for a few weeks?

Title: RE: CCNA "507" flashcards





Jesse,


    I wasn't able to find any for the CCNA, what I did which was helpful in my studying, was I would read the book the first time, just to get an overview, I didn't spend a lot of time studying every detail, but the second time around I had a stack of Index Cards, and I would go through a section at a time and write out my own, for instance on one side I would write "previous command", and on the other side put up arrow or Ctrl+p. While this took time just having created the cards myself was a tremendous study aid. I could then turn around and use them on my 2 hour commute!

RE: 5-4-3 Rule

[Willy Schoots]

his topics seems to come back periodically. Good that I saved my original
reply from a few months back:

The answer has to do with the IEEE 802.3 standards. There are actually two
models how to calculate a "valid" ethernet network.
Model 1: Simplified model widely known as 5-4-3 rule.
Model 2: Calculation of Roundtrip delay (<576 bit times) and Interframe Gap
shrinkage (50 bit times)

In model 1, there can be 5 segments connected by 4 repeaters, but only 3 can
have stations on them (half duplex mode), the other 2 MUST BE link segments
(full duplex, for instance fiber).

Check out this excellent Website of the Ethernet guru: Charles Spurgeon.

http://www.ots.utexas.edu/ethernet/ethernet.html the entrance to his website

http://www.ots.utexas.edu/ethernet/10quickref/ch7qr_5.html#HEADING4
outlines model 1

http://www.ots.utexas.edu/ethernet/10quickref/ch7qr_6.html#HEADING5 outlines
model 2

For a definite source on Ethernet (besides the IEEE 802.3 specs) I highly
recommend his excellent Ethernet book:
http://www.bellereti.com/ethernet/edg/edg.html
Chapter 13 of this book is online and it talks about  the 5-4-3 rule !!!

RE: load balancing on Rip

[McCallum, Robert]

you have answered your own question my friend.  RIP cannot determine any
difference between bandwidth.  Its metric is hops""".  You have equal
paths so it will load balance even if its a 2meg line versus a 64k line.
The message below yours is on fast switching or not... whether it load
balances on a packet per packet basis or on a session / destination basis.

Subject: Re: load balancing on Rip


Hi,

I just wondering what the meaning of unequal cost load balancing doesn't
work on RIP.
>From my experience, I have setup a router that has two paths to the same
destination with equal metric (hop count) and also I set different bandwidth
for each path with "bandwidth" command.
When I check it by doing a ping, the packet goes well on both direction.
I think the unequal cost load balancing could not be done by RIP because it
could not arrange the packet so one packet goes to link 1, next two packets
go to link 2, the next one goes to link 1 and so on (for example : link1 ->
512K, link 2 -> 1024K) like EIGRP does. But RIP still load balance the
packet with equal treatment even the bandwidth are different. Since the RIP
header doesn't include any parameter for bandwidth so how it could detect
the bandwidth of link along the path to the destination ?
Please correct me if I'm wrong.

Thank you

RE: Video conferencing over IP question

[Robert . Schussler]

First off, this isn't a sales pitch, I'm an engineer but I felt like I just
HAD to reply.

RE: your issue about video conferencing using 3 multilinked ISDN lines,
Broadwing sells a frame circuit that goes into our ip cloud and connects to
a Nortel BSN box also known as a "Shasta" box.  This box does firewalling,
sets up ipSec tunnels, routes, etc. etc., whole lots of stuff.  We are also
supporting video conferencing services off these circuits because we can
provide COS (class of service) by ip address via our Cisco GSX (12016)
platforms.  We also sell a Sony h.323 camera that has a 10BaseT connection
on the back and can talk to like cameras or to ISDN based systems
(Picturetel, Polycom) via a third party site.  So, video ain't just for
ISDN anymore.

If anyone wants to know more, email me offline.

Subject: Video conferencing over IP question


We are building a Frame Relay network from scratch. We have 2 main offices
and around 8 remote offices. For equipment the four main offices will have
3640s and the 4 remote offices will have 2620s. Two of the main offices will
100 + users while the other two will have 25 + users. The remaining remote
offices will have 5-10 users. We currently run 3 ISDN lines into each office
for video conferencing and the phone bills are quite expensive. 

We are looking into running video conferencing over the Frame network and my
question concerns what switch I should install in the offices. Right now I
am looking at the 3548 XL at two of the main offices with 2924 XL switches
for the rest of the offices. If video conferencing over IP becomes a reality
in 6 months I was thinking about adding a 5000 series switch at the main
site to have a core/distribution layer with the 3548 XLs serving as the
access layer. I am concerned about the 2924 XLs in the four remote offices.
Should I look into the 3524 XL series for the remote offices to be able to
handle the video conferencing traffic?

Thanks,
Jeff

RE: permanent ISDN connection

[McCallum, Robert]

you can make it stay up with a high dialer idle timeout and make your
interesting traffic whatever your routing protocol updates are. i.e.

interface bri0
dialer-group 1
..
..
..
..

dialer-list 1 protocol ip permit

Rip updates should then cause the dialer idle timeout to reset.

There must be an easier way to do this but for the life of me I cant think
straight.  I am now finishing while most of you are just starting.  Enjoy
your day!!

FDDI, cheap?  Is there some requirement that mandates that you have FDDI?
If you are looking for good, nice and cheaper you might want to consider
migrating your FDDI to fast ethernet.

Multicast adrressing: ip to Mac

[Daniel Boutet]

I am studying for the switching exam and I am converting ip multicast
address to ethernet addresses.
What i don't get is that they state in the Cisco press book (page 294/295)
"the least 23 least significant bits of the ip multicast group are place
into the frame..."
"half of the ethernet block 01:00:5e:00:00:00 to 01:00:5e:7f:ff:ff
correspond to ip multicast"

I really only use twenty when I am converting from binary to hex.

Scenario:  224.138.8.5 (to use their example)
1110  1000 1010  1000  0101
01:00:5e:0A:08:05

Since the 01:00:5e:0 are always going to be,  then I am only concerned with
the least significant 20. Is this right?

I did their exercise on page 319/320  and got 100% (their is an errata for
on of the address but it is a decimal to binary error) but I did not
use the 01:00:5e:0 as the base but 01:00:5e:

Thanks!

CCNA 1 versus CCNA 2

[rick]

Hi all: 
I'm hunting for some feed back on if I should go ahead and
take the CCNA 2 test before I continue on with the CCNP
track.
I passed the CCNA 1 back in May and I'm wondering if there
is a substantial difference in material covered between
track 1 versus track 2.

Your input would be appreciated.

Thanks
Rick

The exam is not changing that much. More layer two switching

books you have with the Cisco web site. Search on layer two switching
and read some of the material.

Permanent ISDN Connection

[Liwanag, Manolito]

Try the config below to get the Dialer and the BRI working.  Just increase
the Dialer idle-timeout to a larger number than 300 (5 min), 30 minutes or
even higher. Depending on the interesting traffic crossing, this should keep
the line up all the time as I am sure than during business hour someone will
be sending traffic to the link within the set time frame.

Hope that helps.

Re: Multicast adrressing: ip to Mac

[Daniel Boutet]

I wanted to add that there is also an errata to the figure 8-5 page 294 of
the BCMSN book by Karen Webb
The 48-bit ethernet address should read:

 0001   0101 1110 0  which converts to 01:00:5e This leaves
23 bit that can be matched to the Ip Multicast least-significant
23 bits.

Re: cannot see route in bgp table?

[Kenny Sallee]

Jason, you should be careful posting your entire config on groupstudy.
Also, the password on the vty's is easily breakable so you should change it
right away.  Your config looks OK but it's hard to say without knowing your
complete topolgy/policies.  If you have the network in your local BGP table,
it should be advertised.  Go on the router and do a "sh ip bgp nei
 advertised"  If you see the networks there, then the problem
may be with your peer.  Also, make sure you have an established BGP session
with the nei.

Check this out:

r7-termserv#sh ip bgp nei 1.1.1.1 ?
  advertised-routes  Display the routes advertised to a BGP neighbor
  dampened-routesDisplay the dampened routes received from neighbor
  flap-statisticsDisplay flap statistics of the routes learned from
neighbor
  paths  Display AS paths learned from neighbor
  received-routesDisplay the received routes from neighbor

Good luck,

Kenny

Re: Multicast adrressing: ip to Mac

[Daniel Boutet]

ok ok ok!!! some of you might think that I was in left field. I think I know
where I went wrong.
I am mixing the 48-bit ethernet address with the conversion process. Let me
explain:

I was adding a full "half octet field" 01:00:5e:0 when it is actually just
one bit (0) from the ethernet address. Group of four bits to convert from
binary to hex.

I actually discover this by replying to my own question.
Sorry for using valuable thread!
Should of tried to understand before asking!

It is 
a very good source for the CCIE written but must be supplemented.  For 
example: the book talks about the RIF and RII but does not go as much in-depth 
as you will need.  
 
It is 
a very good place to start or review.  You can also use it in studying for
