Network Analyzers [7:72346]

2003-07-15 Thread Dave C.
I work for a small growing business and am currently evaluating two types of
network analyzer software.  EtherPeek NX and Sniffer Portable (Sniffer Pro).

Since the versions that I have are not the full production versions (only
for evalutation purposes), I am limited to the functionality I can do with
each.

I know there is an extensive difference in price (Etherpeek NX is somewhere
around $2000-2500 range, and Sniffer Portable (Pro) is somewhere greater
than $10,000.  For a small growing company, it is hard to justify over
$10,000 for a piece of software, when I can get something comparable for
much less, especially when we are in a time where we have to justify our jobs.

What I would like to know, if anyone has experience with both of these
applications, and what capabilities that Sniffer Pro offers, that Etherpeek
NX does not.

I would also like to know if anyone has experience with Ethereal (for
Linux).  I know it is free and it has much less functionality than Etherpeek
NX or Sniffer, but I would like an opinion on that to.

Thanks.

6509 MSFC [7:71340]

2003-06-25 Thread Dave C.
I have a MSFC on a 6509 that I am firing up for the first time.  The 6509 is
running CAT-OS (Hybrid Mode).

I have defined several VLAN interfaces on the MSFC, and now must create a
specific access-list to limit only a certain source and port address to
reach each of these VLAN's.  This access-list will not allow Telnet
connectivity.

My question is, if I create this access list and bind it to all VLANs, will
I be able to SESSION over from the switch to the MSFC?  Does the SESSION
command actually use Telnet to get to the MSFC?  Will I need to assign a
loopback address and then allow access to the loopback address specifically
in my access-list?

I just want to make sure that I do not block all access to the MSFC.

Any clarification on this would be helpful.

Thanks.

RE: 6509 MSFC [7:71340]

2003-06-25 Thread Dave C.
Actually I think I answered my own question.  I believe that it does telnet,
but uses a system default Loopback address (127.0.0.x).  When I session
over, it shows that I came from 127.0.0.y.

Any thoughts...?

VTP Domain Server Question [7:70942]

2003-06-19 Thread Dave C.
I have a question regarding VTP.

I am working with a network configuration that has dual 6509's as core
switches.  One is the VTP domain server, the other is a VTP domain client. 
All other 4000 switches are defined as client also.

I need to take both 6509's down to upgrade the Cat-OS on them, however I am
concerned about what happens to the other switches when the VTP domain
server goes away while the other 6509 is in client mode.

I know that I can assign multiple VTP servers to a domain.  My original
thought is to first make sure that the client 6509 is running the same VTP
revision # as the server 6509.  Then I should be able to change the client
6509 to VTP server mode.  Then in theory either server can take over VTP
responsibilites, because one will be able to act as the other if the other
one goes away.

What I was also wondering, do all VLAN's go disabled if I were to only have
a single VTP server and shut it down when the rest of the switches are
clients?  If so, would this happen right away, or after 5 minutes? If I take
the 6509 server down, it will not be able to tell anyone that a topology
change has occurred, but will the clients be looking for the VTP 5 minute
updates?

If anyone could help clarify this, I would appreciate it.

Thanks.

Dave C.

RE: Help with router config [7:69612]

2003-05-27 Thread Dave C.
No this is not correct.

You should not see an entry of 192.168.0.2 in your route table.  All you
should see is a route to 192.168.0.2/30 (which means two host addresses).

It looks like you have a subnet mask conflict possibly on the other end.  If
you want your configuration to be:

router 1 192.168.0.1

router 2 192.168.0.2

then you need to make sure that both IP addresses have a subnet mask of /30
(255.255.255.252).

Generally /32 (or 255.255.255.255) is used for a loopback interface.  Since
the route is being learned via Serial1/1, I would have someone verify subnet
mask info for that interface at the other end of the circuit.  You may want
to verify your configuration too just to make sure that there are no
secondary addresses configured or something strange like that...

Thats my perspective...

HTH...

RE: Help with router config [7:69612]

2003-05-27 Thread Dave C.
I am sorry, you should see a connected route of 192.168.0.0/30 in your route
table. (Not 192.168.0.2/30 or /32).

I appologize for the typo, but its been a long day!

RE: CCIE Lab - Boson Router Simulator [7:66367]

2003-04-06 Thread Dave C.
I just wanted to let you know that I purchased the Boson Router Simulator
when I was preparing for my CCNP exams.  Looking back, I feel it was
certainly not worth the investment.  I thought that this may save me some
money over buying a couple of routers on eBay, but I would have been better
off with the routers.

I spent a lot of time trying to figure out what was wrong with the
simulator.  Things as simple as configuring a P-P Frame Relay circuit.  I
was never able to get frame-relay to activate.  Some IP routes would not
refresh correctly until a different routing protocol was loaded and
unloaded.  I could go into more detail, but I do not think it is necessary. 
Then I would have to document these issues and send them on to tech support
and wait a day or so for a response.  It seemed to slow me down in my
progress.

Do not get me wrong, the simulator is a good idea (I think if you are trying
to get your CCNA).  For the complex scenarios we have to learn for the CCNP
or CCIE, there is no replacement other than a network of actual routers.

Hope this helps!
