Re: Access list

Incidentally, I have read somewhere--possibly this list--that the McGraw

Security specialization exam.  The only exam material that isn't covered in
the book is PIX firewall information.  Just what I've heard.

Hi,

I'm having a discussion with some colleage's of mine about the management
VLAN.


One says thaty the management VLAN will let trough broadcasts  I'm
saying that it will not let trough broadcasts. The management VLAN is only
to manage your switches and routers by telnetting etc. and it won't let
trough broadcasts..

Am I right or does my colleage win this one :) ??

Hi Peter,


Looking at the show command, there is no layer 3 call.  If your BRI interface gets assigned an IP address by the called router, then you won't be able to pin the BRI IP address until an ISDN call is made (and IP assigned).

VLAN just devide ports to different different broadcast domains. Broadcast
will go only to ports that are in the same broadcast domain.

So broadcast will go thro but not to all ports.

RE: Management VLAN

[Ehab Mohamad Abdullah]

It wont let the broadcast unless you spevified an IP helper Address, because
you have a router in the middle of the VLAN setup, so if you have five VLANs
, they wont be able to communicate with out a router.
and 
It is very well known that routers do not forward broadcast. Only switches
can do so.

Management VLAN - 2

[Jeroen Timmer]

Hi,

Just to point out to some that replyed to my message...

Management VLAN is something different than a normal VLAN. The management
VLAN is mostly on every trunk port of a VLAN configuration. So if I have
about 6 different VLAN's on different trunk ports, the management VLAN would
also be on the trunkports of every VLAN. That's why I posted the question if
the management VLAN (configured on each VLAN domain) will let trough
broadcasts.

Re: can pix act as a proxy ???

[Kristopher B. Climie]

Depends on your definition of a proxy server.  If by proxy you mean as a
cache  engine, then no, obviously not.  But if you mean as a centralized
point of exit to the internet that is capable of hiding your private
network, then yes.  By using TACACS+ or RADIUS, you can even authenticate
users.  The PIX will prompt the user for a username and password on their
first try at getting to the net, then check that u/p with the authentication
server.  Once the server respondes with that users authorization level the
user is granted/denied access to that service.

If by proxy, you mean as a URL filter, the answer is yes, by only in
conjunction with a third part piece of software like WebSense.  All user
requests are first forwarded to the WebSense server and checked for the
policy of it.  If it is acceptible, the request is then passed to the
Internet, but if it is denied the request is denied and either a custom page
can be returned to the user telling them it is a site that violates your
policy, or my favorite, returns a generic site error, making them believe
that the site is down.

Re: Management VLAN - 2 [ long ]

[Scott Nelson]

There is no big mystery around the "management VLAN", it is just a regular
VLAn that the Sup or similar device needs to made a part of to communicate
with the outside world so that you can communicate and manage it.

By default, the Sup modules are part of VLAN one, which you should use as
you management VLAN and put all other traffic on another VLAN if you really
want to make it easier for troubleshooting and a couple other reasons, but
you don't have to do this if you don't want to. It just makes your network
cleaner. If you only have one VLAN and a small network, just leave it that
way.

I make my management VLAN an rfc1918 network, ( IE 192.168.x.x, etc )
so that I am using IP addresses that are blocked from being routed, for
security reasons and that I am not burning IP addresses that don't need to
go outside my network, IE: accessing the internet for HTTP, FTP, etc.

You can put what VLAN the Sup module attaches to, part of any VLAN so you
could make a management VLAN, any VLAN number if you wish. However, the
default management VLAN by default from Cisco and other vendors is VLAN 1.

I would recommend though that VLAN 1 remain the management VLAN for 1
reason, if you add a new switch to the network, it is by default in VLAN 1
unless it is programmed before it is put on the network. Why take a chance
of it being on the wrong VLAN? There have been cases where some switches
just won't work very well in anything else but VLAN 1 for management. Just a
bug in the code. Some switches won't even let you move management from
working out of anything else than VLAN 1. Mostly the older switches though.

If you have under 200 switches/devices on VLAN 1 that need to be managed and
the router goes down or you start having router issues, all of your devices
are already on the same VLAN, which doesn't require routing at this point
since they are all on the same VLAN, then stick all everything else in
another VLAN. I have had NICs go bad and cause some nasty broadcast storms
but since they were on another VLAN, only that VLAN was really effected.

You can have a port setup to be in VLAN 1 so you can attach a workstation to
it to get to your devices in a pinch as you won't be routing at this point
as you will be on the same subnet.
( Assuming you are not doing secondary addressing or subinterfaces on the
router or running on the VLAN )

I even set aside port 1 on all the switches I manage so that when I am in a
closet, I know I have a port to connect my laptop to, to manage the
switches, routers with. I even host 5 addresses on this net from my DHCP
server so that I don't even have to change my settings on my MAC Powerbook.

Did I miss your question? Did this help?

I need to define a network usage policy at work and need your input.

We had someone use a port scanner here a few weeks ago and the same person
just did some large FTP download and upload during the weekend. (he is
either being fire or we are locking down his user profile.)
My boss want me to have a policy spell out to all the staff to what is
acceptable.  I am just starting off and would welcome any ideas.  I will
post what I put together once it is done.

Thanks

If you look around, people who have taken the BSCN mention 30% consist of

it only had 1 question at the time on BGP.  I would look into purchasing a
new BSCN book.

I've recently learned from my publisher that the CISCO version of BSCN book
is delayed for release.   Try Examcram.com.  I'm not sure how good their

RE: Router models?

[Ole Drews Jensen]

Yes that would help.

If you write them down on a piece of paper, I'm sure it will show you a
pattern that will help you memorize it.

The 700:

If the number is even, it has both an S/T and a U port - else it only has an
S/T port.

If the middle number is 6 it only has 1 Ethernet ports, if 7 it has 4.

If the last number is 1 or 2 is has no POTS ports, if 5 or 6 it has 2.


The 1600:

There's not really a pattern, but there are only 5 models.


The 3600:

The third number shows you how many modules slots it has : 3640 has 4.

types of routers ranging from 700, 1600 , 3600 series how many serial ports
they have , how many BRI interfaces they have etc.?

thanks b4 hand

Hello

[kaushal Bhatt]

Friends
 
This is my first post to the group. I am preparing for CCNA 
2.0 and  I am planning to give exam in the coming week.
What I would like to share is that ..before taking the exam.. 
u can test ur skills at http://www.brainbench.com
they offer exam on cisco network support and cisco 
design
I gave that exam on support just few min. back. I suggest to 
go thru this before going for ccna exam.

static route question ??

[jeongwoo park]

HI all.
Situation:
There is a central site in San Francisco, and four
branches around Bay area.
Since static route gives us faster traffic
transmission, would it be the most desirable way to
configure static route on all routers, regardless
whether it is a central site router or branch office
router?
If not, why not?

Thanks in adv.

jeongwoo

Re: How does cisco router load-balancing?

[Darren House]

I thought you could only get per packet load sharing by using CEF.  All
other switching methods allowed for per destination/session load sharing.

I also think (I could be wrong) that if you have E0 process switched and
E1 Fast Switched, the first packet would be process switched, the route
processor would look up the destination in the route table.  The first
entry in the table would be used for the first session, whether that's E0
or E1.  If it's E0, then the 2nd session for the same destination network
would choose E1, because there are 2 equal cost destinations in the 
routing table.  From that point, when the fast cache is initialized on
E1, the router will use E1 for any subsequent session to the same
destination address, as long as that address is still in the fast cache.

If the route table had E1 first, then I don't think E0 would even be used,
because the route table would not be referenced again until the fast cache
entry was removed. 

But once again, these are per destination scenarios, not per packet.

Let me know your thoughts,

Thanks,
Darren

Telephony switches

[Erik Mintz]

Hello All, can I get some suggestions on good books and/or resources to help
me get familiarized with telephony switching, in particular, the
Cisco/summafour telephony switches? I found cisco's online docs for the
VCO/4k, but I am light in experience with telephony switching and need some
more fundamental info.

Thanks,

Re: Network Usage policy

[Dale Holmes]

What you need is an Acceptable Use Policy Statement. Here is a link with 
many examples...

http://www.avana.net/~jtruitt/ferret/auplinks.html

You might also consider developing an information security policy that 
specifically states the things that are absolutely forbidden (port scanning, 
mp3's or other huge bandwidth hogs, adult material, ethnic slander, etc. 
Some of the examples at the above link have this information contained 
within the Acceptable use statement, but others have seperated them. One 
reason to do so is that the Acceptable Use policy statement usually is owned 
(and enforced) by Human Resources, while the Information Security policy is 
owned by IS. The Acceptable Use policy points to the IS policy, allowing HR 
to enforce what you put in your policy statement, but you retain full 
control over the contents of the IS policy and can amend it as you see fit.

I hope this helps (I just finished one for a client of mine).

Dale

Re: configuring 3524 lan switch

[Phil Barker]

Colin,

I normally cut and paste for 2924 and 3524 switches.
i.e do one port by hand in notepad or whatever and
then build up your config via cut and paste editing
the interface number along the way. Then go to "conf
t" on the target switch and cut and paste the lot.

Regards,

Phil.

Re: Modem question

[Vern Stitt]

Hey Mari,

You will never see a 56000 bps connection!  I think the fastest allowed by
telco due to line parameters is 53300.  I usually get 48000 or 51000.  But
after a sustained heavy rain, I only get 16000 or 28000 and once only got
9600.  Must have a crack in the insulation on my line between my home and
the CO.  If you consistently get a low connection speed, you probably also
get noisy voice connections!

Hi Group

When you use a 56K modem to connect to internet,
you never achieve 56K. For example, sometimes it
shows that the bytes sent at 48000 bps, sometimes
45000 bps, everytime it's different. So, where has
those "bandwidth" gone to?? (<--please correct if
I'm wrong on this) So, can I conclude that a 56K
modem is only theoretically 56K???

Re: The H1-B visa program is a fraud.

[cryptobyte]

ElephantChild, I say it has alot to do " ... about getting certifications,
..."  If you have a Certification, but no experience, what is it called or
what is the state, status of your certification - you are a PAPER .
At least, that is what is advocated by some; therefore, at least, in part,
this is applicable whether you are a CCNA, CCDA, CCxx, CCIE, xNx, MSxx,
etc. [Extended to Novell, Micrsoft, ...]

At least with Cisco devices, at the lower end, it is hard for people to
beg, borrow or steal an entry level position.  And then, to paraphrase,
they must pay there dues and proceed with their career.  At the upper end,
sacrifice and hard work, money, prestige, status and on going work to stay
current.

In that it follows the path of least resistance, Capitalism starts to
acquire the properties of electricity.  Capitalism is a predicated on the
ability to produce and sell a product [or service] at the least expense
for the highest margin possible.  If your type of services are needed and
you are a bono fide, card carrying CCxx, MSxx, xNx, you have expectations
about market value, time in industry, what you know, who you know, how
much you know, etc.  To repeat, you have expectations of what you are
worth.

What happens, since you want x money and you can't get any work because
you are just a PAPER  at your new expertise level because joe/jane doe
will do the work for a fraction of what you have come to expect, probably
deserve and the market used to bear.  [Union shops come to mind.]

Suddenly, H1B and Certification are entwined - up to your and my neck.
Then, to take it a step further, what happens when an H1B starts under
cutting another H1B.  At that point, we are all on a downward spiral - if
not already.

Other than,  "It's not on topic ...", please explain your position
ElephantChild.

Re: configuring 3524 lan switch

Phil,

Thanks for the info, so you don't know if there is a command to change speed, duplex, 
vlan membership etc, in the ios 6500 there is a command interface range  to do this and you can specify ranges in the catos, why not in the 3500.

Hello,

Is it possible to associsate the switch ip address with a vlan other than
the vlan 1, in 1900 switches?

I know in 6000 series switches you can associate the switch ip address with
the vlan you line and make it management vlan.

Dark fiber is fiber that is not being used. ie, no light is passed through
it, hence the term "dark"

Re: [Re: Modem question]

[Petra Hofmann]

Some additional information is required here.

First, the maximum limit is 53K (US) imposed by the line voltage restriction
place upon telcos in the U.S.  The speed reported is for only the instant it
was measured as the connection changes dynamically over lifetime of
connection.  There can be only one A-D conversion in the line which terminates
at the telco switch with a trunk side T-1.

Re: configuring 3524 lan switch

[Phil Barker]

Colin,
I'd hedge my bets that their isn't one. The 6500's
IOS is obviously non 11.xx IOS. I'm using version
12.0(5) onthe 3524's and the inference is to use a Web
interface to configure multiple ports, which I suspect
is cut-and-paste at the end of the day.

Regards,

Phil.

OT: Life expectancy of Fiber Optic Cable

[mike delp]

I have been in a discussion with a telco about fiber backbones, and they
heard something about the life expectancy of a fiber cable.  I have reviewed
the manufacturers specs, and I can't find any mention of this.  Has anyone
heard anything about this??

TIA

  According to my calculations the problem doesn't exist.

Re: auto-negotiate not reliable

[Dale Holmes]

Different vendors implement auto-negotiate in different ways, and sometimes 
those ways are at odds... There is no way to tell whether the firmware in a 
given vendor's NIC is going to respond and react as Cisco expects it too in 
an autonegotiation process. As a general rule of thumb, regardless of 
vendor, when it really matters - explicitly set it... don't do 
auto-negotiation.

Re: Ip helper address

[Donald B Johnson Jr]

I don't understand this, wouldn't the client accept the second offer by
sending the seconds servers siaddr in the request packet. also DHCP standard
says that nowhere must a client accept the first offer and then stop
broadcasting. All servers will answer the clients DHCPDISCOVER broadcast
with any help it can or can not offer. The first server does not tell the
second server to shutup so as soon as the (second or 1nanosecond slower
server) receives the broadcast it will it will send a DHCPOFFER packet and
the client will reply with an DHCPREQUEST packet to the second server
(using the siaddr field) that will be ack'd by the second server with an
DHCPACK packet. This is all made quite clear in RFC 1541. So you can have
two DHCP servers on the same segment you just don't know which one will
serve the address to the client but both will try independent of each other
and the client will ot stop trying after receiving after a nack from a
server.

1 down, 3 to go!!! (question) ;)

[NeoLink2000]

Hey Group,
I just passed the BCMSN this morning with a decent score of 803/1000. I only 
studied for this test for a month and a week. I was scared that I was going to fail it 
because this was the first time I scheduled a test before even finishing a book. I 
guess I gave myself a deadline, which I am not going to do again. I need to relax ;)  
I have a question now. I want to go for my BSCN but it's still not out (cisco press). 
I know I can read the ACRC and a couple others but I just feel better when I have the 
new stuff. I did a search and found this book. I have seen them around and have the 
CCIE all in one study guide by them but I don't know how their credibility is. Here is 
the info "McGraw Hill Text; ISBN: 0072124776" This is a BSCN book but if it's not good 
I will just go with the BCRAN and wait for the big one to come out. Please, any insite 
on this publisher/book will be appreciated. Thanks group,

Mark Z ~ CCNA, CCDA, 1/4-NP

Re: The H1-B visa program is a fraud.

[Dick Silva]

/
A thought that occurred to me is.how do all the H-1Bs get experience
when supposedly the U.S. is so much more technically advanced than most
other countries?

Maybe U.S. corporations do not require H-1Bs to have experience because they
work for so much less.

As I said,  just a thought.

RE: auto-negotiate not reliable

[Healis, Jim]

I have seen problems like this with certain NIC cards, in particular my
experience has been poor with 3Com PC Cards.  Also, auto-negotiation seems
to be problematic between Sun machines and Cisco equipment.  The best I can
tell is when both sides are set to "auto" they never are able to decide on
one setting or the other and eventually fail due to the numerous errors on
the interface that accrue while trying to negotiate.
I have always played with the settings on the switch port until I see no
errors.

RE: auto-negotiate not reliable

[Roan, Wayne]

That is correct.  The cards and the switch will continue to "negotiate" for
every tranmission.  You need to change one of them to a certain speed.  They
are both trying to figure out which speed to run at.  If you make one run at
a certain speed, this problem will go away.  I always set the NIC to a
certain speed 10 or 100.

RE: what is dark fiber?

[Stanfield Hilman B(Brad) CONT NSSG]

The obvious answer here is... "It Depends"
If you search on Dark Fiber, you will get a number of answers.

Dark fiber refers to unused fiber-optic cable. Often times companies lay
more lines than what's needed in order to curb costs of having to do it
again and again. The dark strands can be leased to individuals or other
companies who want to establish optical connections among their own
locations. 

In this case, the fiber is neither controlled by nor connected to the owning
company. Instead, the  leasing company or individual provides the necessary
components to make it functional. 


Please let this thread die... The last 20 posts have done nothing to further
the knowledge gained, only repeat the explanations over and over and
ultimately waste bandwidth.

Re: Ip helper address

[Dale Holmes]

Perhaps I should be more clear about this and say that this is the behaviour 
of MICROSOFT DHCP clients. Here is the info from the Windows NT Resource 
kit:

"Note:   The client accepts the first offer it receives, regardless of 
whether the offer came from a DHCP server on the local subnet or from a DHCP 
server on a different subnet. ... In the case where the DHCP server is 
unavailable or there is no available IP addressing information to lease to a 
client computer, the client is unable to bind to TCP/IP."

An MS DHCP client may receive many DHCPOFFER's for its DHCPDISCOVER 
broadcast. It will accept the first offer it receives (actually, the first 
response it gets), and NACK all others. If the first response it gets is 
negative, it will settle for that, and NACK anything from the other servers. 
I have seen this (and sniffer traced it) in production. MS was unwilling to 
call it a bug, and said the behaviour was by design and was RFC compliant. 
Case was closed...

This was NT 4.0 Service pack 4 with Win98 clients. I dunno if they have 
changed things since, but I doubt it.

Excessive collisions

[Lonnie Paschall]

I have a 4500 with a two port Ethernet module. Each port on the module
connects to a different 2924 switch and is in a different subnet. I keep
getting excessive collisions on the Ethernet interfaces, no runts, no
giants, no CRC errors, just collisions. Any thoughts? There is no command to
set the duplex or speed on the module.

Thanks,

Lonnie

Re: what is wire-speed?

[Priscilla Oppenheimer]

At 03:17 AM 9/11/00, you wrote:

>What do you mean by interfame gap? is it the address?

The interframe gap (IFG) is the required gap between frames. Per the IEEE 
802.3 (Ethernet) specification, between frames, there must be silence on 
the wire for the time to transmit 96 bits, which is 9.6 microseconds on 10 
Mbps Ethernet. (I'll let you do the math for the higher speed Ethernets). 
The IFG gave NICs the time to recover in the olden days when they weren't 
as fast as they are today.

>What about ingress and egress issue? how do they calculate it?

Counting ingress would be cheating, if you ask me. I've never heard of a 
vendor doing that, but I wouldn't put it past them. As we have said, this 
is all marketing showmanship.

Re: can pix act as a proxy ???

[Kenneth]

I don't think that it works as a proxy server but you can enable NAT to let
people access the internet using a private ip address.

Re: Core Layer Design

[Gabriel]

The only thing "between" the core equipment and the distribution equipment
is cabling... network equipment is either a part of the distribution layer,
or a part of the core layer. (Or a part of the access layer.)

Cisco's recommended model is that the core consist strictly of layer-2
devices in order to maximize throughput; with high-performance layer-3
switches reaching the market, that's a less pressing consideration than it
used to be. For most applications, having your distribution-layer equipment
route to a layer-2 core is a good way to do things; however, multicast or
other advanced applications can benefit from a layer-3 core.

Most small-to-medium networks are not going to fully realize Cisco's Access/
Distribution/ Core model anyway; it's far more of an enterprise-network
design model than a universal paradigm.

Perhaps if you gave more concrete examples of what you're trying to do or
what your environment is?

Re: BGP on 2600?

[Gabriel]

I agree with all the below- in fact, my introduction ot the Cisco networking
world was through that configurator tool; I've built my networking knowledge
from product configurations back to theory instead of the more usual
reverse. It is occasionally flaky, and infrequesntly broken, but it by and
large is an excellent tool.

It doesn't let you configure an NM-1FE into a 26xx, though, even though it's
a working configuration.

RE: The H1-B visa program is a fraud.

[Sam Adams]

I thought H1-B were suppose to be paid at market rate?

BTW, it takes about 3 months to transfer a H1-B so if the foreign workers do
not like their jobs then they have no recourse but work until it is
transferred.  Or not work until it is transferred.  They don't have it easy
either.

IMHO, it seems that the only winners are the companies who hire them.

when supposedly the U.S. is so much more technically advanced than most

Maybe U.S. corporations do not require H-1Bs to have experience because they
work for so much less.

Re: Excessive collisions

[John Neiberger]

What are the stats?  "Excessive" is highly relative.  You may be seeing a
lot of collisions, but that would be expected if you have a lot of traffic
through that port. If there is no setting in the 4500 for speed or duplex,
then it is running 10 Mbps/half duplex.  In half duplex world, collisions
happen by design.

and a couple others but I just feel better when I have the new stuff. I did

in one study guide by them but I don't know how their credibility is. Here
is the info "McGraw Hill Text; ISBN: 0072124776" This is a BSCN book but if
it's not good I will just go with the BCRAN and wait for the big one to come
out. Please, any insite on this publisher/book will be appreciated. Thanks

Re: password and enblepass commands on catalyst 6509

[Gabriel]

When you get a "Usage: blahblah" response to a command, it means that your
syntax was not correct, and that you need to use the 'blahblah' syntax
instead of whatever you did. IF you had correctly set the password, it would
have said "Password changed" or some such thing.

You should have done something like this:

6509-1> (enable) set password consolepass
> Usage: set password
6509-1> (enable) set password
> Enter old password:
etc.

Hope this helps...

Re: Ip helper address

[Ejay Hire]

It is possible two have two DHCP servers in one subnet.  The client will 
accept the first IP address it recieves.  This is done to remove the Single 
point-of-failure in the one DHCP server.  Some DHCP server software will 
allow two or more servers to share a synchronized copy of the address pool 
database, to simplify administration.

Getting to the question...

According to the Cisco Press ACRC book, if you have multiple ip 
helper-address ('S) defined, any UDP broadcasts recieved on the allowed udp 
ports will be unicasted to each of the IP helpers.

It's not just DHCP either, it's:
DHCP, DNS, TFTP, TIME, NETBIOS NAME SERVICE, NETBIOS DATAGRAM SERVICE, AND 
TACACS.

I don't understand this, wouldn't the client accept the second offer by
sending the seconds servers siaddr in the request packet. also DHCP standard
says that nowhere must a client accept the first offer and then stop
broadcasting. All servers will answer the clients DHCPDISCOVER broadcast
with any help it can or can not offer. The first server does not tell the
second server to shutup so as soon as the (second or 1nanosecond slower
server) receives the broadcast it will it will send a DHCPOFFER packet and
the client will reply with an DHCPREQUEST packet to the second server
(using the siaddr field) that will be ack'd by the second server with an
DHCPACK packet. This is all made quite clear in RFC 1541. So you can have
two DHCP servers on the same segment you just don't know which one will
serve the address to the client but both will try independent of each other
and the client will ot stop trying after receiving after a nack from a
server.

Re: static route question ??

[Gabriel]

In a static topology, there's no need for a dynamic routing protocol. Only
when the lack of flexibility and slow (manual) reconfiguration become issues
do you need to think about routing protocols. For a simple, stable network,
use static routes.

I thought H1-B were suppose to be paid at market rate?

BTW, it takes about 3 months to transfer a H1-B so if the foreign workers do

If there are no redundant links, then static routing will be faster.
If there is a redundant link, Dynamic routing will give the benefit of fault

Re: Fast Ethernet on 2612

You can, and it does work, but it's not a Cisco-supported configuration. I'm

I've verified this with NM-1FE's... haven't tried with the new FE/WIC

Doesn't a MS client go for a new server after 87.5% of the lease if It can't

I got a resource kit collecting dust somewhere what page is that on I'd like

Maybe you should e-mail them the RFC.

Re: Excessive collisions

[Gabriel]

If you have the old NP-2E, your ports are 10mbps half duplex. If you have
the newer NP-2E-FDX, you have the option to set port duplex on the RJ-45
ports (not the AUIs) with the commands HALF-DUPLEX or FULL-DUPLEX at the
config-if prompt.

You can't set speed on a 10mbps module. The NP-1FE does support the SPEED
command, but if you have a 2-port ethernet module it's definitely just
10mbps.

Re: auto-negotiate not reliable

[ROUTHIER, YVES]

for your information 

Catalyst 2900 10/100 ports automatically adjust to the Ethernet speed
and duplex mode of the attached segment. First, 802.3u is implemented to
negotiate the link's
speed (10 or 100) and duplex mode (half or full). If the attached device
will not autonegotiate, that is, is not 802.3u compliant, the Catalyst
2900 will autosense and
configure to the speed and duplex mode of the other device.

Re: Excessive collisions

[Kevin Wigle]

Older models of the two port ethernet module for the 45xx series do not do
full duplex.  Newer models (last year or so) can do full duplex. (I think)

No models do 100 meg, you need a FastEthernet module for that so you can't
config speed.

So I would wager that you have 2 ports of 10 meg half duplex.  Configure
your switches accordingly.

You may want to set your switch speed to 10Mbits an match up your duplex

Re: The H1-B visa program is a fraud.

H-1Bs are not paid at market rate even though it is federal law.

In Clearwater, FL there is a company that recruits only H-1Bs from other
countries.
One of their salesman was being interviewed by the local newspaper, St
Petersburg Times, and he was naming off the advantages of hiring foreign
workers, and I quote, "We just placed one man in Boston for $55k/yr if it
had been an American they would have had to pay $85K/yr".
I keep wondering about that level playing field George Bush Sr was always

Re: static route question ??

[Priscilla Oppenheimer]

Just being picky, but I can't see how static routing would give you faster 
traffic transmission than dynamic routing. The router still looks into the 
routing table and finds a route for the first process-switched packet. From 
then on it uses the fast-switching cache, (unless configured not to do so.) 
But just because it's a static route instead of a dynamic route doesn't 
make it any faster.

Static routing uses less bandwidth because no routing updates are sent, but 
that's a different concern. Also, dynamic routing protocols can be slow to 
converge when problems occur, but fast-converging protocols such as EIGRP 
and OSPF wouldn't have this problem. Also, if you just have single links 
and no redundancy, there's nothing to converge to anyway.

Static routes will work but could get cumbersome to configure and maintain 
as your network grows. Also, do the branch offices just need to get to the 
central office, or do the branches talk to each other? If so, a default 
route or a routing protocol might be a better option to avoid having to 
specify each network.

Re: static route question ??

[willy george]

Static routes does seem the best way to go in your situation. If it is a hub and spoke 
arrangment as i believe it to be in your case then static routes must be configured on 
the central router pointing to the networks on the remote locations and static routes 
must also be configured on the remote routers pointing to the networks on the central 
location.
There is definitely a performance advantage using static routes in this case.
Hope i have been of some help
Willy

PIX to access inside server

[SH Wesson]

I am using a Cisco PIX 520 with an inside interface and an outside 
interface.  I have
the following scenario:

Internal server has an address of 10.10.1.150, the external server has an ip 
address
of 128.200.111.100.  The external server is in the dmz zone.  The internal 
server has
been assigned a global address 0f 128.200.111.150 that maps to the inside 
server
of ip address 10.10.1.150.  I want the external server of 128.200.111.100 to 
be able to
communicate with the inside server only through port 135.

I assigned a static ip address to the inside host with the following 
command:

static (inside,outside) 128.200.111.150 10.10.1.150 netmask 255.255.255.255 
0 0


I assigned the permission for the external server to be able to access the 
inside
server only via port 135 using the following command.

conduit permit tcp host 128.200.111.100 eq 135 host 128.200.111.150 eq 135


Is this the right way of doing it?  If I'm doing it wrong, can someone show 
me how to do this.

Thanks.

Priscilla Makes some excellent points about switch performance 
and performance benchmarks.  A couple of extra notes on the 
subject.  There are actually some RFCs that cover this topic, 
namely RFC 1944 (somehwat relevant), RFC 2285 (relevant), RFC 
2289 (adds to RFC 2285).  Both of the 2200 series RFCs are 
titled, "Benchmarking Methodology for LAN Switching Devices."  
Please keep in mind, they are informational, and as such do not 
represent an Internet Standard.  Additionally, there was an 
excellent Networkers brief that covered this very topic from 
the bowels of Cisco's testing labs :-)  It was pretty 
informative and if anybody is interested, I can dig up the URL 
for the presentation.

HTH,

Paul Werner

p.s.  The definition of a 64 byte packet?- Ethernet 
marketing packet :-)

I don't know what controls are in place to enforce the law.  But I would
think that someone tooting his horn about cheap foreign workers is asking

Re: static route question ??

[jeongwoo park]

Thanks for your reply
Just want to clarify what I meant.
When I said that static route gives us faster traffic
transmission, it meant that static route's
administrative distance is 1, which is lower than
other dynamic routing protocols' administrative
distance.
Can I say this?
Please correct me if I am wrong.

Thanks in adv.
