4 Port Serial Interface on 2600 [7:66518]

2003-03-30 Thread Larkin, Richard
I note the 4-port serial interface (NM-4T) is not supported on the 2600, but
I recall having an older image which did list the interfaces, but I can't
recall the image version.

Does anyone know what version of IOS will support this module?

RE: bandwidth [7:61552]

2003-02-10 Thread Larkin, Richard
I would bundle the two serial interfaces together using Multilink PPP, then
place access control on the router so customer's can't talk to each other,
then apply rate limiting to each customer with guaranteed 64k, burst
additional 64k and do rate limiting on bundle (if that's possible).

This is generally what telco's are doing with Metro ethernet switches,
except traffic is segregated by either VLAN or MPLS VPN.

 how i will tell the s1 to use that bandwidth wich is not utilized by

 limit command.

The method I told you before is based on the link still in use approaching a
certain bandwidth. At that point it can take over the other one. I realize
that's not quite what you want.

I don't think there is a way to have the link still in use take over the
other link when that link utilization goes low. Anyone know?

If we don't get an answer, start another thread and explain the situation
with more detail. That will get people's attention.

Good luck.

  If you had two serial interfaces between two sites, you can
 tell a router to
  use the second one when utilization gets to a certain point
 with the backup
  command. For example, let's say you had S0 and S1. S0 could
 start using S1's
  bandwidth when its utilization reached 60% and stop using it
 when it fell to
  5% with the following command.
  
  int s0
  backup int s1
  backup load 60 5
  
  But that's when the two interfaces go the same place.

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

You may need to use Priority Queueing, and hardcode telnet High prio based
on an access-list.

Normal traffic despools after telnet queue is empty. If you are sure that
there will always be bandwitfh left for other traffic, PQ will do fine.

That is one way of using it.


During transmission, PQ gives priority queues absolute preferential
treatment over low priority queues; important traffic, given the highest
priority, always takes precedence over less important traffic. Packets are
classified based on user-specified criteria and placed into one of the four
output queues-high, medium, normal, and low-based on the assigned priority.
Packets that are not classified by priority fall into the normal queue.
Figure 7 illustrates this process.

Congestion Management Overview
http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/12cgcr/qos_c
/qcpart2/qcconman.htm


Why Use Priority Queueing?
PQ provides absolute preferential treatment to high priority traffic,
ensuring that mission-critical traffic traversing various WAN links gets
priority treatment. In addition, PQ provides a faster response time than do
other methods of queueing.

Although you can enable priority output queueing for any interface, it is
best used for low-bandwidth, congested serial interfaces.

Considerations
When choosing to use PQ, consider that because lower priority traffic is
often denied bandwidth in favor of higher priority traffic, use of PQ could,
in the worst case, result in lower priority traffic never being transmitted.
To avoid inflicting these conditions on lower priority traffic, you can use
traffic shaping or CAR to rate-limit the higher priority traffic.

PQ introduces extra overhead that is acceptable for slow interfaces, but may
not be acceptable for higher speed interfaces such as Ethernet. With PQ
enabled, the system takes longer to switch packets because the packets are
classified by the processor card.

PQ uses a static configuration and does not adapt to changing network
conditions.

RE: FR Low Latency Queuing (LLQ) [7:59820]

2002-12-29 Thread Larkin, Richard
This is something I am researching currently. I believe LLQ is CBWFQ+PQ and
the PQ is strict. This means that anything above the allocated rate is
dropped. This is fine for voice traffic where you reserve say 200kbps for 8
voice calls, and anything more than that is dropped, but not suitable for
data applications. You will need to use CBWFQ for your data apps, not place
them in the PQ.

The CBWFQ will guarantee bandwidth to PC1 as you mention in your first post.
I would say that the PQ only gives you 30k due to slow start after packet
loss.

Finally, why CBWFQ gives you sometimes 100k, sometimes 50k, - I can
understand it giving you more than 80k, if there is more available, but I'm
not sure why it gave you less. Perhaps the application or operating system
applied some congestion control. I believe Win2k or XP does a lot of good
work to not hog all of the WAN bandwidth. At this stage, I would question
the appropriateness of FTP as an accurate traffic generation tool.

As to the ping times, your bandwidth under the priority condition is only
guaranteed up to the amount reserved. Anything above that is dropped if the
Q is strict. PC1 would get better response if the ping traffic was in the
PQ, but it isn't so it is placed in the same Q as all the FTP traffic. Then
within the PQ, your ping has to sit at the end of a bunch of FTP data. I
wouldn't be surprised if your ping traffic from PC1 was actually worse that
PC2. PC2, under CBWFQ, would be more fair to small ping packets than many
large FTP packets.

RE: simple network setup [7:59937]

2002-12-29 Thread Larkin, Richard
Yes you can load share - but it wouldn't load share any individual flow - I
believe this ensures the order of packet arrival is correct.

If a link went down, I'm not sure about the packets in the interface queue
(ie, those that had been placed on the outbound interface queue) but I would
suspect they would be lost, so yes, you may lose a packet or two.

A much much much easier way is to use a PC, load the dummynet image on a

Dummynet works on FreeBSD or, as we do, you can download the version that

Traffic Shaping and Queuing [7:59258]

I want to be able to allocate min guaranteed bandwidth per application as
well as use priority queuing for Voice on an edge router.

Shall I use Custom queuing, which assigns min bandwidth per application, or

is the best choice.

I understand Custom Queuing and how it provides min bandwidth, but am not

and if so, does the shaping occur before or after the queuing?

Can anyone shed some light on this matter before I go back to what the ref

RE: Software for Statistical Profiling [7:58277]

2002-12-01 Thread Larkin, Richard
Thanks for the info - I was looking at using the ErlangC model due to the
nature of computer networks. Currently, my modelling is based on assuming an
application takes 2 seconds to complete a task if it had 32kbps of bandwidth
reserved for it, I can use the Erlang model to calculate whether 95% of
transactions can be completed within say 2.3 seconds (with the 0.3 seconds
being queue delay) - but by changing the bandwidth I change my underlying
assumption of 2 seconds. Ie, if I allocate 64kbps, then the application may
only takes 1.2 seconds and my model changes accordingly.

The traditional Erlang model applies well on a packet-by-packet basis (just
like queues of people in the bank, etc), but I'm not sure of its
applicability to a series of packets on a whole which make up a transaction.

it only takes a handful of questions to get wrong and you're a goner!

Thanks for your valuable advice!

Did you use MPLS and VPN Architecture (CCIP Edition) by Cisco press to
prepare for your MPLS exam?? If the answer is YES, Do you think the material
of this book is related to the actual exam?

Thanks.

RE: MPLS for 2500 [7:53353]

2002-09-17 Thread Larkin, Richard

Definitely yes with PPP - a new NCP (MPLSCP) provides indication that the
frame is an MPLS frame instead of an IP or IPX frame. MPLS is treated as
just another network layer protocol.

Not sure about HDLC though.

MPLS'ers,

Assuming you find the IOS that supports MPLS on the 2500
or 2600, is it possible then to set up a little MPLS cloud
with HDLC or PPP links connecting the routers?

Alternatively, we have used the MPLS routers as access
devices to connect to a FR cloud (ATM too but we don't have
the ATM switches yet). But we'd like to just use three or
four inexpensive 2500/2600 routers with HDLC/PPP serial
links as the cloud. Can it be done?

-- TT

RE: QOS ?? help needed [7:52961]

2002-09-11 Thread Larkin, Richard

Quick question - where does traffic shaping fit into all this. If I do
traffic shaping on outbound traffic from a 3640, I presume that occurs AFTER
the classification (ie, the shaping is the last step)?

Andy,

This is a problem for Q Man! (whoever and wherever he is)
But seriously, maybe we could work this one out on the list. May I suggest
that you use the modular QoS CLI. This involves three steps:

First, classify the packets using ACLs and the class-map command. Second,
apply actions to the class using the policy-map command. Third, attach the
policy to an interface (input or output). Fourth, enjoy your network.

Anyone else want to take it from there?

Hi Group,

i am having problems to solve the following scenario.

   kabelmodem-(E0)router2501(E1)  -
witch  -  win2k-pro  (private address range)
   ( internetaddress )( using
   -  win2k-server  (private address range)

i want to prefer udp-packets with port xxx over all other traffic (specially
http)
(leaving the win2k-pro in direction to kabel-modem, with all other traffic i
mean traffic from win2k-pro and win2k-server,
  specially http)

is this possible?

i tried priority-queueing:
priority-list 1 protocol ip high list 120
priority-list 1 protocol ip normal
priority-list 1 protocol ip low tcp www
access-list 120 permit udp host 10.0.0.2 any range   int e 0
priority-group 1

but the result wasn' t efficient.

also i tried route-maps with precedence flash-override as high and routine
as low, but i dont know whether it is the right way solving the prob nor the
configuration works.

i was searching on the cco and trying to solve the problem for many hours. i
need your help. any suggestions?

RE: Passing Score for MCAST+QOS [7:52470]

2002-09-01 Thread Larkin, Richard

I found it challenging, but certainly not as difficult as the MPLS exam
which has a much higher pass mark and I have failed twice to date.
For the QoS+Multicast exam, I didn't read the Multicast Cisco Press book,
only the IP QoS book, plus some whitepapers/documentation - and I struggled
- so I would recommend both books.

hi,

as far as i remember the passing score was 720.
the answer to your second question depends i would say. i found it one 
of the most difficult exams i had so far. but you can make it. be prepared

RE: Stuck in rxboot mode on 2524 [7:51780]

2002-08-21 Thread Larkin, Richard

We had the same problem last month on an old 4000.
The solution, from memory, was to use the config register or boot system
command in the conf t global mode.
I remember we did o/r 0x2102 and the next boot showed the config reg at
0x2102, but it was still in rxboot mode.
I think the next step was within the configuration.

Memory a bit rusty - but it may help trigger some ideas.

I just attempted an upgrade on a 2524 from 11.0 to 12.2 and am now stuck
rxboot mode. I followed the instruction to the letter and rebooted from
0x2101 to 0x2102 and the config register is showing that is is now 0x2102
but it is still in rxboot mode. My upgrade of the IOS failed also. At the
end I got a checksum error. Right now I just want to get back in regular
boot mode. Any suggestions appreciated. thx Randy

 I have been following this group for some time now and am very 
 impressed by a few of the regular posters and I have some questions 
 for them. How do you get all of your knowledge and information? For 
 example I just read Howard Berkowitz OSPF tutorial from the 
 Certification Zone and it is very very good. I was very impressed at 
 the detail Howard went into the tutorial and his knowledge. The same 
 goes for Pricilla. How do you guys get all your knowledge?

You are very sweet to flatter me so. :-) I have learned so much because I
have been doing this for over 20 years. I think Howard has been doing it for
over 30 years (plus he is a genius! Seriously.)

Other tips:

Really do read RFCs and IEEE documents. If you want to be like Howard, get
involved in the development of RFCs. Read the drafts. Join the mailing
lists.

Analyze protocol behavior with router show and debug commands, and, of
course, with a protocol analyzer. (You knew I would say that!)

Don't be afraid to try weird stuff in your lab. Chuck Larrieu can be our
inspiration there! ;-)

Choose your books carefully. Skip the silly Get rich quick, get Cisco
certified books. When trying to decide if you should buy a book (if you
have physical access to it, such as in a bookstore), look it over carefully
for good writing and technical accuracy. Choose a subject that you know well
and see what the author says about it. I choose TCP, for example. If the
book makes it sound like all you have to know to understand TCP is that
there's a 3-say handshake, I put the book back on the shelf (hopefully
hidden so nobody else will buy it either.)

Here's a list of the books that I think are the best in our field:

http://www.troubleshootingnetworks.com/books.html

Priscilla 

 In the tutorial it talked
 about the Dijkstra algorithm and how Howard is working with a group 
 and changing the route computation. Wow!! Where did you learn to do 
 this? I'm in the process of studying for my CCIE and I want to be an 
 Internetworking Expert. When I think of an expert I think of people 
 like Howard, Pricilla, Jeff Doyle, and I am wondering where can I go 
 to learn all that they know. Do you guys memorize stuff? Because there 
 is so much to learn I wonder how you remember it all. I'm just 
 wondering because I want to be like you guys. I know to be like this 
 it is not easy but I am willing to work at it.
 
 
 
 Second question is what type of ISDN interface would I need to connect 
 to an ISDN switch? Where can I go to find this information? Thanks

Hi,

I am proposing the following LAN solution to a customer.  Does it make
sense?

-WS-C4006-S3(sup III engine)
Do I need special licenses for this?  The customer will be using IP and IPX.
I saw some licensing software for the Sup III that was around $1700 for both
IP and IPX.  I don't know that that is all about.

-One 48 port RJ45 blade for servers and workstations on same floor

-One 6 port GBIC blade (WS-X4306-GB) that will be used to connect to five
WS-2950s on different floors

-I will use the WS-5483 GBICs to connect the 2950s to the six port
WS-X4306-GB

Can anyone think of things I haven't considered?

Thanks
Wayne
