Re: urgent

what kind of cable are you using to interconnect switches? direct or crossover?

are all pc's connected by switch 1 and 2 with same network and network mask?

Re: urgent


If you mean:
Whatever connected to port 10 Switch1 can talk to whatever connected to port 10 Switch2 only,

In this case you need a simple ACL in the 3500 to this job.

For ACLs on the 3500, check this:

But on the 2600 you don't have ACLs, but
you can have IP lockdown utility that enables you to restrict incoming traffic on a port to a specific IP address/subnet and deny all other traffic on that port.

for port security on the 2600 check this:

There is another simple way /trick,
use for both devices connected to port 10 on switch1 and switch2 a dedicated IP/Subnet different from the one used for your network, but this will not work if you need to access some other resources bu these devices.

Good Luck !!!
