Re: Cisco VS Foundry Networks.. [7:36448]

2002-02-25 Thread R34RV13WM1RR0R

Foundry makes great products!  On product in particular that blows Cisco
away is their ServerIron Load Balancers.   Cisco made a big mistake by
buying Arrowpoint, and badging them the CSS line of equipment.  As far as
Foundry's switches go, they are very comparable.  They use a Cisco replica
command set, so if you know Cisco, you can adapt to Foundry fairly easily.
So all in all, Foundry is a good product, worth consideration for a lot of
different applications.

***SWITCH CONSOLE COMMAND*** [7:56849]

2002-11-04 Thread r34rv13wm1rr0r
Hello all,

When repairing a failed flash in 6509 w/MSFC I had to use the switch console
command to be able to set up the boot boot variable for the router since the
flash was replaced.  I do not have physical access to these boxes on a daily
basis but I can reach them via a console server or SSH.  Problem is that when
I use the console server to get to it it goes directly to the MSFC because
during the repair I used the switch console command, I want to switch the
console port back to the switch Supervisor but here is what it tells me.

SWITCH> (enable) switch console
This command is not supported on telnet session

OK, if the command is not allowed on a telnet (SSH) session then how do you
switch the console port back since I can't "console" into the Supervisor?

Seem crazy to be only able to switch it from the console, but the console
only
works for the  MSFC.

Thanks!!!

Cisco Telephony Questions [7:57293]

2002-11-12 Thread r34rv13wm1rr0r
Hello,

I am trying to put together a case study pertaining to Cisco Telephony,
if
any of you experience with this subject matter would respond I would greatly
appreciate it.

Thanks.


1.  Does Cisco use IP Telephony?  If so, how?

2.  What are the major business capabilities to Cisco that are achieved by
using IP Telephony?  i.e. increased productivity, lower long distance costs

3.  What are the advantages of using IP Telephony over traditional voice
systems?  i.e. shared network/phone equipment, support costs, more features
(if so, what)

4.  What are the disadvantages of using IP Telephony? i.e. network congestion
causing latency

5.  How does it perform over Frame Relay?

PC-Card Flash Question [7:48619]

2002-07-11 Thread r34rv13wm1rr0r

Is there any way to copy images to the PC-Card based Flash using a laptop,
either with a special card reader or using software and the PC-Card slot on
a laptop?  I am just curious if I could copy IOS images for distribution to
the Flash card using my laptop then take card to the devices and load IOS
version.  (In situations where TFTP isn't feasible or the best option.)

Thanks.

Re: flash copy failed checksum error [7:51834]

2002-08-21 Thread r34rv13wm1rr0r

It is also possible that your bootflash is faulty, as I have just had one go
bad in a 6509.  1 out of 3 times it would actually verity the CatOS images
OK, most times it would say bad CRC checksum and I tried different downloads
and TFTP servers to make sure the images was fine.  Cisco RMA'd a new flash
and now it is as good as new

Re: MLS between 2 Cat5K with RSM [7:51841]

2002-08-21 Thread r34rv13wm1rr0r

If I am not mistaken, and forgive me if I am since it has been a while since
I worked with a 5k/RSM setup.  I believe that you only need to incorporate
the MLS IP RP stuff if you are in the "Router on a Stick" configuration
meaning if you have a some 72xx or 75xx's out there doing your VLAN routing.
Being that your RSM is incorporated into the switch you should do some sh
mls xxx  on your switch to see that MLS should be running by default, and
there is no need to apply that configuration.  I know for a fact this is
true on the 65xx platform, but I am sure it also applies to 55xx/RSM also.
16 RP addresses would be external routers ONLY.

Good Luck,

Anthony

Re: A HUB can work in Full-duplex mode? [7:52973]

2002-09-10 Thread r34rv13wm1rr0r

No.  The collision domain on a hub is shared throughout causing each port to
listen before transmitting.  A switch on the other had limits the collision
domains by port therefore allowing the host to transmit at will.

Re: Duplicate packets with same SEQ #'s... [7:53024]

2002-09-11 Thread r34rv13wm1rr0r

The tcpdump is being run on a gig span port on the core 6509, the only
vlan's the span encompasses is the Server VLAN's.  The VLAN's are being
spanned on both core switches, so I can see why in the intrusion database
duplicates are showing up since both servers are seeing the same VLAN's.  I
wonder why when TCPDUMP is run on once switch it sees duplicates.  Like I
said, I can see why the ACID database sees two entries if both servers are
set on the same spanned VLAN's, but it does explain why the duplicates are
notice when tcpdump is running on only one Linux Server.  The host that is
running tcpdump is only using 1 gigabit NIC, so no chance of seeing the
packets from another interface.  I guess it isn't that big of a deal, I just
want to find out why it is happening, the Security folks are a litle annoyed
with getting two entries in the database every time.  I will evaluate
spanning-tree and what not, but it seems there is some deep rooted
explanation for this.

Thanks for all of your replies... keep 'em coming!

Switch MAC filter [7:54880]

2002-10-04 Thread r34rv13wm1rr0r

Is there a way on a 6509 to filter a port from seeing a traffic from a cetain
MAC when the two hosts are on the same VLAN.  The problem is one host keeps
broadcasting NTP updates every 40 secs and the Pix SYSLOG is contantly
logging
it.  Since the NTP host does not go through the firewall I was wondering if I
could block the MAC address all together at the port the Pix is plugged into.

Thanks..
