Eduardo,
The MSFC it's self is a decent treasure trove. You may want to see if they are using the same SNMP strings between the 
MSFC and the 6500 chassis. I have seen a lot of places use different passwords on their L2 and L3 gear, but still use 
the same SNMP strings.

Good luck,
Dan

Francois,

Thanks for your help, I did it and now I know where the SUP is
located, unfortunately the passwords I had didn't work there. Anyway I
know where to dig for new access.

Greets,
Eduardo.

Hi,

Thanks for the tip, I forgot to say, i'm in a Cisco Catalyst 6500 with
IOS 12.1(8b) and there's no sh mac-address-table command available.
I do have the enable password, show privilege give me level 15. All
references to interfaces are to Vlan# but no physical ports anyway.

Then you are in the MSFC module of the switch and it is running in hybrid
mode.

you need to "sh cdp neighbor detail" to find the ip address of the SUP
card of the switch and telnet to it.  From there, it will be CatOS
commands.


Is there a separate port for switch configuration and router
configuration?, i have other Cisco devices for testing and i found
the show mac-adress-table useful, but with IOS 12.4. Is it a problem
with IOS version?

Thanks,
Eduardo.

Hi,

I'm pen-testing a network and i've already gained access to a Cisco
switch in certain VLAN; i'm stucked in getting a SPAN port in the
physical port where i'm attached or changing that port to a different
VLAN; "show interfaces fastethernet" doesn't work, and "show
interfaces" just output the MAC address of the VLAN, but i can't find
the way to correlate IP (mine) with the physical port (Fa0/3 i.e.).

Some idea?

Thanks,
Eduardo.
