How to get the running config of routers using SNMP

2000-07-13 Thread Chan Dovelet

Hi,

My company have about 50 numbers of Cisco routers. I
want to backup their running config. I do not have
Cisco Work. Can I use SNMP to get their config? What
is the MIB id?

Regards.
Dovelet

You can have E1 line with all 32 timeslots used for data. It
works, really, we have such lines. But, if the line is too
long, there could be problems and you could receive 'frame slip'
errors.

Re: Off topic: how is that possible?

2000-07-13 Thread Bharat Suneja



As long as you are on the Internet, you 
can communicate with your mail servers hosted anywhere by any ISP no the 
Internet. Which ISP you use to get your Internet access is totally 
irrelevant.
For instance, you get your Internet access from some Indian ISP like 
VSNL. They give you their own IP addresses from the Class Cs assigned to them. 
Using those IP addresses, your routers/network is connected to the Internet. The 
router/proxy might be using NAT so you can use private IP addresses on your 
internal network - and if you are in India with your LAN connected to ISP, this 
is most likely the case.
 
Your mail/web servers hosted with some hosting company in the US are on the 
Internet, using valid Internet IP addresses. That's how you can "talk" to your 
mail/web servers in the US. The fact that your own router/proxy/network is on a 
different network/subnet and your mail/web servers are in the US on a different 
network/subnet is totally irrelevant - as long as you are on the Internet it 
does not matter, you can talk to each other.
 
As far as DNS is concerned, it can have entries for hosts on different 
networks. For instance, in your domain itself, it could have an MX entry for 
mail servers pointing at your Exchange Server in India, and point the web server 
(www.indchem.com) to some web server in the 
US, and yet again point your intranet server (intranet.indchem.com) back to your 
network in India (as long as it has valid Internet IPs).
 
Hope this helps. Let me know if you still have questions.

  Hi listers,
  Im actually a newbie to this list. Could 
  someone tell me how Im getting my mail trafficked onto my exchange server. The 
  reason why Im asking is this my domin is hosted by some ISP somewhere in US 
  but our corporate HQ is somewhere in Asia forget bout where we are 
  sitting!
   
  We are (HQ) hooked to the Internet thro a 
  local ISP on a dedicated link using "global static IP addresses" for browsing 
  and for mailing through our MS-Exchange mail server. Im 
  just wondering how they go together I find that my www.x.com address is different from the 
  ones given by our local IP address range.
   
  If a mail arises in where do they travel go 
  across before reaching my mail server?
   
  How the hosting of "www site" and the mail 
  server which are with different ISPs in differrent part of world are goes 
  together ofcourse with all the ftp,dns stuffs.
   
  Can someone pour some light to this I will be 
  very much grateful to them

Re: How to get the running config of routers using SNMP

2000-07-13 Thread Sasha Milic

Chan Dovelet wrote:
> 
> Can I use SNMP to get their config? What is the MIB id?

Variable is:


writeNet OBJECT IDENTIFIER ::= { lsystem 55 }

writeNet OBJECT-TYPE
  SYNTAX   DisplayString
  ACCESS   write-only
  STATUS   mandatory
  DESCRIPTION  "Write configuration to host using TFTP."
::= { lsystem 55 }

Usage:
==

Set variable 'writeNet.ip_address_of_tftp_server' to value 'tftpfile',
where tftpfile is file name into which the config will be saved. Keep
in mind that, depending on tftp server you are using, it may be required
that specified file already exist, with mode 0666 (on unix). It may be
different on your system, but on Solaris it is so.

In perl, with cmu snmp package, it would be:

# begin

$session = new SNMP::Session
   (
   DestHost  => "$Router_IP_Address"
   Community => "public",
   Timeout   => 1,
   Retries   => 3
   );
 
$session->set( 'writeNet.192.168.1.1', "router-confg" );

# end


Hope this helps.

Howards white paper on Routing Principles ? certificationzone

2000-07-13 Thread Phil Barker

Hi group,
Just about finished this excellent paper but have
come across the following issue.

under the heading of "IP Fragmentation"

>>> SNIP
On a FDDI medium with a 4500 byte maximum frame size,
you have 4436 bytes available for payload in each
frame. This payload includes 8 bytes of LLC/SNAP, 10
bytes of IP, and 20 bytes of TCP. There are also 20
bytes of FDDI frame overhead.

In the ideal case, there is a single transmitter
sending sequential frames. The theoretical efficiency
is 98.5%. With a 1500 byte frame payload limit, the
transmitter would need to create three frames to carry
the same information. Since each frame would add a
packet, you would add the framing, LLC/SNAP, IP, and
TCP overhead on each packet. Adding two additional
frames adds 144 bytes of overhead at all affected
layers, a small amount of overhead when compared with
the overhead you would incur in fragmenting on WANs.

>>> END SNIP

>From the first paragraph.
I agree with 8 bytes of LLC SNAP.
and I agree with 20 bytes of TCP header.
But I think 10 bytes of IP should also be 20 ?
And the overall sentence should read that the
remaining header i.e 4500-4436 = 64 consists of
(8 + 8 + 8 + 20 + 20) = 64
(Dest mac + Source mac + LLC/SNAP + IP + TCP)

Can anyone confirm ?

Phil.

Hi All

I managed to pass CCDA exam today on my 1st attempt. 755 to passgot

marks coz i thought me going to fail after doing 30 qns

Me got 4 case studies and all of them appear in the 1st 1/3 of the qns.
Quite demoralise initially coz so many case studes and all require extensive

Wondering why i got 0% for Network Manangement Thought i answer all
those qns correctly!

But the exam really tough!! not so striaghtforward n make me thinks!

Re: Bus Topology and Ethernet

2000-07-13 Thread Joel Studtmann



10Base5 and 10Base2 (coax), are run in both a 
physical and logical bus.  A physical bus is NOT a physical ring.  In 
a ring, the two ends are connected to each other.  With 10Base2, both ends 
have a 50 ohm terminator (one grounded).

  Ethernet (as well as token ring) use a

Re: Someone clarify this?

2000-07-13 Thread joel.studtmann

Or, in common cases, someone didn't know what they were doing, and have two
logical networks sitting on one physical one.  Common cause is an expansion
in the number of computers on a segment, and rather than adjusting the DHCP
scope, they create a second dhcp scope.

Very inefficient when the two computers need to talk to each other, as the
packet has to be sent to the router first)

::sigh::

I've seen THAT one done before.

Granted, it could have been planned that way, if they are using VLANs and
the computers are on different switch ports.

yes, Vlans makes that posible.
VLAN configurations happens at the switch when VLAN IP interfaces
are created to defined a VLAN colition domain on that switch.
So, the switch may have 24port 10/100BaseT modules which you can
asign at each port or the whole module to be a member of a specific VLAN
group thus alowing colition control and at the same time the braking down of
your IP address schem. Communication between VLANS happens at the RSM Route
Switch Module in the switch where your subnets routing will occur.
Each VLAN# must have an IP interface at the core otherwise routing will not
occur.
When the station boots up it will send a request for an IP in the case of
DHCP. If DHCP if properly configured with default routes for the  specific
subnets, that is, " Interfaces on the Switch", it will only asign IP
addresses to the stations connected to that switch module.

Hi all!!
I am a fresh college graduate.
While I was reading Cisco book at the school computer lab today, I was
curious about some network concept.
Could somebody clarify this?
Here it is.
This computer lab is set up with window NT workstations.
I was wondering what the ip address of each workstations will be. So, I
checked ip addresses of each stations by going around each stations by
typing -ipconfig-- at command prompt.
So, I was able to figure out those machines' ip addresses.
When I was doing this, I also found that the ip address of the computer
sitting right behind my original station had different subnet ip address
from my original station' s subnet ip address.
The station behind my station: 130.222.235.90/24
My station: 130.222.224.40/24
I know that it is DHCP server that assigns the different ip addresses to
clients. However,
these two machines are sitting on same computer lab, but each one belongs to
different subnet. And all these computers are connected to a switch.
Is it VLAN concept that makes it possible?
Would this be also possible without the VLAN configuration on the switch?
I was wondering if two machines could sit next to each other having
different subnet ip addresses.
The guy in charge of the computer lab didn't seem to be familiar with
configuring VLAN on his switch.
As far as I know, the station behind me can't send any data to my station or
the other way around without the external router intervention if they belong
to different VLANs. I hadn't checked if my station could talk to the station
behind me because I didn't know how to do it.
Could someone clarify this?
I will appreciate your help
Thanks in advance.

Re: 2 questions

2000-07-13 Thread Lawrence Dwyer


"That depends" on what you mean when you say "the # of subnets" with the mask
12. It can be 1 or several thousand depending on how far down you wish to move
the mask. There is only the given network until you change it. A /12 broken into
/24's would give you  4,096 (2^12).
>From your examples of /12 and /20 below, I think what you are missing is you
seem to only be counting those possible subnets at the next octet boundry.  You
say that a /12 would give you 16 and /20 would give you 16 subnets with a 2^4.
True, but that is ONLY if you were to break the /12 to /16's and the /20 into
/24's (octet boundries). What if you wished to break /20 into /25's for smaller
offices or /23's for much larger ones? Then you would have 32 and 8
respectively. (I know I am not using the -2 part of the process because we are
discussing the binary form of possibles, not the textbook "usable" subnets).
But a /20 mask from  your /12 example would give you 2^8 (256) subnets, not 16.
If you decided on a /21, then it would be 2^9 (512), a /22 would be 1024.
VLSM subnetting is just taking a current defined network range  and moving the
bits of the mask farther down to use those numbers more efficiently.

RE: I think I was right??? (PPP question)

2000-07-13 Thread Rik Guyler

I think you are right.  I do not know of any mechanism within PPP to
actually perform the address assignment.  In my experience, I have always
had to use a DHCP server or assign a static pool of addresses to use, which
would indicate another mechanism external to PPP at work here.

Nice catch!

Subject: I think I was right??? (PPP question)


Hey Groupies, 8)
I've got a question for you. Today I was called by a headhunter. After 
talking about what I was looking for he asked me if he could test me on my 
CCNA knowledge. The questions were multiple choice. There were 10 questions 
and I got 8/10 right. One of the wrong ones, I know I got wrong, but the 
other I'm skeptical about. It was something about PPP, and the answer was 
that PPP assigns IP addresses itself for it's communication. I don't think 
this is right. I have worked on labs where we configure the encapsulation
for 
PPP, and we assign our own IP addresses. So I don't know why the answer
could 
be "totally" correct. I tried to go through my CCNA books, and even tried to

find this in my CCDA/CCNP books but found nothing on PPP assigning it's own 
IP's. Can somebody let me know if I was right, and if I am wrong could you 
point me towards a link, or page numbers proving this info. I want to call 
this guy back and let him know if his test was wrong. I think it would make 
me look a lot better, even though he said I did great. So basically my 
question is: Does PPP assign it's own IP addresses? Thanks for the help

RE: Modem baud rate

2000-07-13 Thread Rik Guyler

The only way to really get 56k (53k) is to eliminate one of the
digital-to-analog conversions.  You do this by using digital modems (modem
cards) rather than analog modems.  For example, an AS5300 contains digital
modem cards inside as well as the DSU components.  You plug your T1 directly
into the back of the unit.  In this manner, you are not converting the
arriving signal back to analog one last time.  This allows you to reach the
higher speeds.  As mentioned before, an ISP would now have all digital
equipment, but modem-to-modem still adds that last conversion, which limits
the speed.

As far as a domain field, I don't think there is anyway for a router to
*directly* add that into the authentication.  What you can do, however, is
set the router up to query a Raduis or TACACS server, which can perform
lookups on an NT user database.  Cisco sells this product, but you can get
free Radius servers around the WWW.

Hope this helps.

saw that we really wouldn't get very much improvement on regular users
dialing in if we upgraded out 28.8K's to 56K V.90.  I can't answer the other

Re: Someone clarify this?

2000-07-13 Thread Jorge Rodriguez

That's  absolutely truth !! Idealy one wants to have a whole grou/department
located on the same area be members of one VLAN, Subnet. Not just mixed
within the same group. Aldough, you can create VLANS/departments for
specific stations for department managements, but it is not common or seldom
done.

I completely agree, someone didn't know what they were doing !

Or, in common cases, someone didn't know what they were doing, and have two
logical networks sitting on one physical one.  Common cause is an expansion
in the number of computers on a segment, and rather than adjusting the DHCP
scope, they create a second dhcp scope.

Very inefficient when the two computers need to talk to each other, as the
packet has to be sent to the router first)

::sigh::

I've seen THAT one done before.

Granted, it could have been planned that way, if they are using VLANs and
the computers are on different switch ports.

yes, Vlans makes that posible.
VLAN configurations happens at the switch when VLAN IP interfaces
are created to defined a VLAN colition domain on that switch.
So, the switch may have 24port 10/100BaseT modules which you can
asign at each port or the whole module to be a member of a specific VLAN
group thus alowing colition control and at the same time the braking down of
your IP address schem. Communication between VLANS happens at the RSM Route
Switch Module in the switch where your subnets routing will occur.
Each VLAN# must have an IP interface at the core otherwise routing will not
occur.
When the station boots up it will send a request for an IP in the case of
DHCP. If DHCP if properly configured with default routes for the  specific
subnets, that is, " Interfaces on the Switch", it will only asign IP
addresses to the stations connected to that switch module.

Hi all!!
I am a fresh college graduate.
While I was reading Cisco book at the school computer lab today, I was
curious about some network concept.
Could somebody clarify this?
Here it is.
This computer lab is set up with window NT workstations.
I was wondering what the ip address of each workstations will be. So, I
checked ip addresses of each stations by going around each stations by
typing -ipconfig-- at command prompt.
So, I was able to figure out those machines' ip addresses.
When I was doing this, I also found that the ip address of the computer
sitting right behind my original station had different subnet ip address
from my original station' s subnet ip address.
The station behind my station: 130.222.235.90/24
My station: 130.222.224.40/24
I know that it is DHCP server that assigns the different ip addresses to
clients. However,
these two machines are sitting on same computer lab, but each one belongs to
different subnet. And all these computers are connected to a switch.
Is it VLAN concept that makes it possible?
Would this be also possible without the VLAN configuration on the switch?
I was wondering if two machines could sit next to each other having
different subnet ip addresses.
The guy in charge of the computer lab didn't seem to be familiar with
configuring VLAN on his switch.
As far as I know, the station behind me can't send any data to my station or
the other way around without the external router intervention if they belong
to different VLANs. I hadn't checked if my station could talk to the station
behind me because I didn't know how to do it.
Could someone clarify this?
I will appreciate your help
Thanks in advance.

RE: I think I was right??? (PPP question) (answered)

2000-07-13 Thread Stull, Cory

Rik,

I am going from memory here but this is what I think...  PPP doesn't
actually perform the address asignment, however it does have to be used to
give the dialing in station its address.DHCP needs to use PPP's IPCP
negotiation to the dialing in computer in order to assign the dial in
computer its IP address. If you think about it, your dialing in using
PPP as your link layer protocol so it has to have some means of negotiating
the IP address assignment, on a local LAN then DHCP would use UDP...

Heres a link..  question and answer # 28  is what your looking for..

I have looked up books for this explanation but cannot find any. What is

ipx on a 804 router?

2000-07-13 Thread Niraj Palikhey

Hi,
I have a 804 router that I tftp'ed an ip/ipx ios to flash. When I do a sh 
flash, I see a TinyRom, the ip ios and the new ip/ipx ios. But when I do a 
sh ver, it shows the older ip ios. I cannot configure ipx routing on this 
router or igrp? The config register is set to 0x2102. Is this the setting 
that I need to change for the new ios to take effect? What would it be?

Aside from this, Is there a book that explains basic things like this? I 
have read many Cisco CCNA books but none of them focus on basic things like 
this which I feel is so important to know. All the books talk is about 
passing the exam, that's all.

Please advise.

As far as I learned, no ip directed-broadcast meaning that
your router will not forward broadcast sent to a subnet.

This may be important for your network being abused to sent

Re: no ip directed-broadcast?

2000-07-13 Thread Michael Fountain

no ip directed-broadcast  -  this means that someone can't ping your 
networks broadcast address.  This was used in denial-of-services attacks.  
Someone would ping the broadcast address, and every machine on the network 
would answer.

no ip mroute-cache  -  this should only be used on slow (T1 or slower) 
serial interfaces.  It turns off route-caching for multicast packets.  On 
slow links Cisco says that it takes more memory and processor time to cache 
the routes and look up the cache then it does to process switch the packets.

2000-07-13 Thread Bob Edmonds

If you look on page 105 of the BCRAN book it says that PPP uses NCP to
configure Layer 3 protocols not necessarily the Layer 3 address.  IPCP is
the NCP used to establish and configure the IP protocol.  But on the other
side why would you use an NCP to have the PPP session support the protocol
and not the individual station address?

Strange tunneling

2000-07-13 Thread Kiarash Bodouhi


Hi all,

I have a 1mbps wireless line between two points. As the wireless has got
around 10% loss, I wonder if there is a way to setup a tunnel on the
line to get a clear link by sending lost packets again. I should 
say that L2TP is good but it assumes packet loss as congestion and
stops sending traffic when detects high packet loss on the line.

Many thanks 
Kiarash

RE: Acrc to be done

2000-07-13 Thread Dennis Laganiere

Why don't you take a look at the new track?  The ACRC is about to disappear,
and if you're studying from scratch anyway, the focus of the BSCN is
tighter.  You need to really know and understand BGP, EIGRP, and OSPF; and
these are great things to learn anyway.

I'd offer you the stuff I've compiled to prep for the BSCN, but I put them
up on ebay a few days ago and there have been several bids, so I'm committed
to dispose of them through that channel.  

One of the neat things about the BSCN is that instead if being required to
type out full text statements you can select them from a pull down box with
a huge selection.  If you know your commands for the three routing
protocols, you should do fine.

Routing Tables

IBM Gurus - Please Help!

2000-07-13 Thread Don Dettmore

I need some help from somone that knows SNA and DLSW.  I am trying to
connect LU6.2 Nodes to a Host on the other side of an IP WAN - in an
all ethernet LAN environment.

My network is pretty complex, but basically it comes down to this:

EthernetAPPNnodes <-> CiscoRouter <-> IPWAN<-> CiscoRouter <->
EthernetAS/400

Currently I am Bridging non-routable traffic over the WAN - it DOES
work but does no seem to be a very good solution - I am chewing up
some bandwidth bridging things I don't want to.

Here are my questions:

1. Can I be selective on what I bridge?  Bridge SNA only?  I have not
been able to find any commands that let me do so.

2. Would using DLSW help?  Is it even possible - using the Ethernet
DLSW BRIDGE_GROUP comands on both ends?  Would that help in any way? 
Eliminate LLC2 timeouts (though I don't think I'm experiencing any)? 


3. Are there any other solutions?

Any insight would be greatly appreciated.

RE: Routing Tables

2000-07-13 Thread Feliz, Edgar

G,
 
You are partially correct. There are a few other things to consider though,
like how much bandwidth will be taken up my the advertisement of routing
update (DV)? How fast do you want your network to converge in the event of a
failure? How robust is the routing protocol I am choosing? Does it support
VLSM, Classless routing? Is it a standards base protocol or is it
Proprietary? These are some of the questions that go along with deciding
which routing protocol to use. Priscilla's book is great if you are
interested in more details.

Re: Routing Tables

2000-07-13 Thread Johnny Dedon
Title: Routing Tables



If I can add my two cents, the end result is to find the 
nexthop for the "best route" to the destination.  Link state protocols 
provide each router with the information to construct a complete map of the 
network.  Only changes are then propagated between routers.  Distance 
vector routing protocols route by rumor. Each router gets his copy of the 
routing table based on his neighbor's point of view.

2000-07-13 Thread Paul Coggin



You can use filters to prevent unwanted traffic from being bridged such as
MS Netbios broadcast coming from PC's etc.

DLSW works great for optimizing SNA traffic across the WAN and allowing it
to be routed across IP  bacbones. It can help with time outs etc and
yes it works with Ethernet.

I built a 75+ router network with Ethernet connected AS400's and PU 2.1
SDLC controllers utilizing DLSW+ over a Frame Relay WAN and it worked
great.

Take alook at the followig url's:

http://www.cisco.com/univercd/cc/td/doc/cisintwk/idg4/nd2007.htm

http://www.cisco.com/warp/public/697/3.html

http://www.cisco.com/warp/public/697/8.html

These Cisco books also have some good information on SNA\IP networking.

  >>

You have to remember that link-state will go by bandwidth, delay, etc. The 
routing tables in link-state will be more efficient and will usually have the 
better path to the destination if configured properly. If you were running a 
rip network (distance-vector) the calculation of the best paths would be done 
by hop count. For example: You have 4 routers (a,b,c,and d) and A is directly 
to D running a 56k link. B is connected to C, which is connected to D. In 
between B and C, you have a T1, and between C and D, you also have a T1. If 
you were running RIP (distance-vector) it would chose the 56k path because it 
has less hops to the destination (D), even though it would probably be faster 
to get to D through C over the 2 T1's. With link-state protocols, they would 
look over the bandwidth and see that the fastest way to get to D would be 
through the two hop path of C. Ok, I confused myself! Too much writing 
without pictures :)  I hope you understood this blabber and hope it helped at 
all,

VoIP & Discontinous IP address

2000-07-13 Thread Ibrahim



 
Hi,
 
We setup small VoIP 
gateway using Cisco 1750 & FXO Card. Here is the diagram 
:
 
 
 Cisco 
1750  A (WAN Interface using Public IP) -- LAN (Public IP) 

    
|
    
|
    
 Internet 
    
|
    
|
Cisco 1750 B (WAN 
Interface using Private IP) -- LAN (Public IP)
 
From Cisco 1750 A, 
we can make connection to Cisco 1750 B ... but after the phone ring, we can't 
hear any sound (I suspect the RTP can't be sent to cisco 1750 
A).
And from Cisco 1750 
B can't make connection to Cisco 1750 A.
 
The VoIP 
configuration is working well on the normal LAN (not using private 
IP).
 
Is it because on the 
Cisco 1750 B WAN site using PRIVATE IP (discontinous IP) address 
?

Can someone point me to where I can find the syntax of setting up a menu
on a 2511 access server.  For example, when users telnet to the terminal
server, they'll get a menu that lists which servers are attached to which
port; they can enter 1 to get into joe.blow.com and 2 to get into
stone.blow.com.  Thanks first.

Re: I think I was right??? (PPP question)

2000-07-13 Thread prabs

Wrong!
PPP has 2 processes which take care of link establishment and Ip Address
assignment.: LCP and IPCP
IPCP is the one which takes care of Ip address assignment from the pool defined
, if any, or from the peer Ip Address.
TO confirmm this , follow the below steps.
Enable : debug PPP nego on a router.
make a call ( modem or digital) from another router or a modem and see the debug
messages.
It will clearly show you the IPCP component
Coming to the DHCP part you mentioned : DHCP / Static Pools / Dynamic Pools /
using peer IP addresses/ are merely different ways to *get* the IP address , but
assigning the IP address to the incoming USER / Call is done by PPP.

hope this helps
p.s: x'cuse my spellings..my keyboard is all screwed up today

Re: Howards white paper on Routing Principles ? certificationzone

2000-07-13 Thread Priscilla Oppenheimer

It should say 1432 bytes left over for payload once you subtract the 
following bytes from the maximum FDDI frame size of 4500 bytes:

20 bytes for FDDI
8  bytes for LLC/SNAP
20 bytes for IP
20 bytes for TCP

This would be counting the preamble, starting delimiter, frame control and 
FCS for the FDDI frame, but not counting the ending delimiter or frame 
status symbols. Also, FDDI doesn't really have a maximum frame size. It has 
a token holding timer which results in approximately 4500 bytes being the 
maximum a single station can send.

And the following words from the white paper should be tweaked a bit: 
"Since each frame would add a packet, you would add the framing, LLC/SNAP, 
IP, and TCP overhead on each packet. Adding two additional frames adds 144 
bytes of overhead at all affected layers, a small amount of overhead when 
compared with the overhead you would incur in fragmenting on WANs."

The first frame would have 68 bytes of overhead: FDDI, LLC, SNAP, IP and TCP.

The two fragments would have only 48 bytes of overhead. The TCP header is 
not replicated in an IP fragment. IP fragments just have an IP header and 
data. Still a small amount of overhead, as the paper says.

Let me know if I've said anything wrong. Thanks.

Priscilla

which router for BCMSN

2000-07-13 Thread David Sanderson

I would like to get a catalyst of my own to practice configuration
excersizes from the BCMSN (Karen Webb /Cisco Press) book and take the test
later.  I have access to a 2524, 1602, 2501 routers and limited access to a
catalyst 5500.  Anyone know what might be the lowest cost catalyst that runs
the same IOS/set commands as a 5500(5000series) catalyst.  I've seen some
ebay items that say "runs the same IOS as a catalyst 5000"  but only on the
catalyst 2901; open for suggestions, Thanks Dave

I would suggest using DLSw versus RSRB.  With DLSw you can set up an access list
to allow only SNA and apply it with the lsap-output-list command or use dlsw
icannotreach commands and filter on the saps like F0.

I need some help from somone that knows SNA and DLSW.  I am trying to
connect LU6.2 Nodes to a Host on the other side of an IP WAN - in an
all ethernet LAN environment.

My network is pretty complex, but basically it comes down to this:

EthernetAPPNnodes <-> CiscoRouter <-> IPWAN<-> CiscoRouter <->
EthernetAS/400

Currently I am Bridging non-routable traffic over the WAN - it DOES
work but does no seem to be a very good solution - I am chewing up
some bandwidth bridging things I don't want to.

Here are my questions:

1. Can I be selective on what I bridge?  Bridge SNA only?  I have not
been able to find any commands that let me do so.

2. Would using DLSW help?  Is it even possible - using the Ethernet
DLSW BRIDGE_GROUP comands on both ends?  Would that help in any way?
Eliminate LLC2 timeouts (though I don't think I'm experiencing any)?


3. Are there any other solutions?

Any insight would be greatly appreciated.

RE: How to get the running config of routers using SNMP

2000-07-13 Thread Karen . Young


copy run tftp may be faster, but there are times when you may want to use
SNMP instead. For example, when you have a large number of devices and you
want to track changes to the configs. Use SNMP to back up the config if it
detects a change. You can then script things to compare the previous config
with the new config, parse out the changes, and e-mail them to everyone in
your "need to know" group. Up to date notification of possibly icky changes
- documented. :-)

There is another mechanism that is used in conjunction with PPP to assign IP
addresses,  but it is Not PPP alone.  IPCP (Internet Protocol Configuration
Protocol) is used assign IP addresses to hosts over a PPP link.  So, yes you

Hello all, I had a 
question regarding BCMSN. The question being can you pass over BSCN and still 
pass the BCMSN exam. The problem being, I can't find any material on 
BSCN but there a few books on BCMSN.
 
Just wonder is 
there any overlap between the two exams. Would it be better to 
wait and take BSCN first. Regards,

Hi there 

I dont see any routing statements i.e router rip , network 10.0.0.0 ,network
10.0.10.0 etc

Your router needs a 'map'  to show it how it can pass network info from one
segment to another .
Dont worry about asking so called stupid questions because your 'stupid'
questions teaches a lot of people out there whom you dont know .

Hope it helps

I feel pretty stupid - I've just passed the CCNA this past Friday

Re: Question regarding Building Cisco Multilayer Switched Networks

2000-07-13 Thread Roman

Do them in whatever order you wish.  If you want to study BSCN, don't wait 
for a book
that says BSCN.  Go get Routing TCP/IP (CiscoPress) for the EIGRP, OSPF 
stuff and
Internet Routing Architectures (also CiscoPress) for the BGP stuff.  Then...
get your lab going and start studying!

RE: ipx on a 804 router?

conf t

To remove the old IP only version of IOS:
delete (filenamehere)
squeeze flash 

The squeeze flash actually removed the file that was marked as deleted in
the previous step.

The best reference for commands like these are CCO or the book that ships
with each new router.

Subject: ipx on a 804 router?


Hi,
I have a 804 router that I tftp'ed an ip/ipx ios to flash. When I do a sh 
flash, I see a TinyRom, the ip ios and the new ip/ipx ios. But when I do a 
sh ver, it shows the older ip ios. I cannot configure ipx routing on this 
router or igrp? The config register is set to 0x2102. Is this the setting 
that I need to change for the new ios to take effect? What would it be?

Aside from this, Is there a book that explains basic things like this? I 
have read many Cisco CCNA books but none of them focus on basic things like 
this which I feel is so important to know. All the books talk is about 
passing the exam, that's all.

Please advise.
Thank you.

A search through COO has proved unsuccessful.  I have an IGX 8410

- P-bit Parity Errors
- C-bit Parity Errors 
- BIP-8 Card Errors
- Out of Frame Errors (sometimes)

I found on COO what the errors mean, but not what causes them.

Reversed Telnet

2000-07-13 Thread Ole Drews Jensen

I am currently reading the BCRAN course companion from McGraw Hill, and the
term "reversed telnet" is actually starting to get a little unclear for me.
I thought I knew it, but now I'm not sure anymore.

Let's say I have two 2501's : RouterA and RouterB

I have used the IP HOST command, and RouterA now knows RouterB as BRAVO.

1)

Is it Reversed Telnet to connect RouterA to RouterB via the console cable
and then from RouterA access RouterB by typing in the command BRAVO ???

2)

Is it Reversed Telnet to connect RouterA and RouterB to a HUB and then from
RouterA access RouterB by typing in the command BRAVO ???

If someone has a way to describe the term so a 6 year old can understand it,
I would appreciate it.

Thanks,

Ole

  If I can add my two cents, the end result is to find the 
  nexthop for the "best route" to the destination.  Link state protocols 
  provide each router with the information to construct a complete map of the 
  network.  Only changes are then propagated between routers.  
  Distance vector routing protocols route by rumor. Each router gets his 
  copy of the routing table based on his neighbor's point of view.
