Hi Friends,

I have two switches Enterasys and four computers as below:


switch 1 - Enterasys B3 with:

Computer A in port ge.1.1
Computer B in port ge.1.2


switch 2 - Entreasys B3 with:

Computer C in port ge.1.1
Computer D in port ge.1.2


The two switches are linked by port ge.1.48.

All computers are in same network 10.0.0.X/255.255.255.0.

 

I need this result:

Among Computer A, B and D: comunication it's permited

Between Computer A and C: comunication it's permited too

But among Computer B, C and D: no comunication it's permited

 

In ohter words:

If in machine A I type "ping 10.0.0.A" or "ping 10.0.0.B" or "ping 10.0.0.D" or "ping 10.0.0.C", the result must to be a answer

If in machine A or B or D, I type "ping 10.0.0.C", the result must to be no answer

If in machine C I type "ping 10.0.0.A", the result must to be a answer

If in machine C I type "ping 10.0.0.B" or "ping 10.0.0.D", the result must to be no answer

 

The question:

I tried to create a VLAN for machines A, B e D and other for C, but the result it isn't the above.

What I have to type in each switch for get the objective with success?

 

Thanks,

Rogerio

Hi Edson,
I eliminate host D and change number of ports, but the question is the same. 

I need that: Host A talk with B and C,  but  B don't talk with C.

With the configuration below, when in host A I do a ping to B, I have a answer, it's right, but if I do a ping to C, I have no answer, it's unexpected.

Follow the commands that I have typed and the output of "show vlan" on both switches.

And I am from Brazil.

Thanks,
Rogerio

Hi Edson
This problem is solved.
The switches configuration are correct. The problem was in the interface of host ethernet of host C. I correct it and then all is OK.
Thanks,
Rogerio
