VLAN Question.. STUMPED!

Hey everyone, I searched through the group to see if this had already
been answered.. but I seem to be hard pressed to find any real answers.
 Hopefully someone here can clarify this for me.

I've been practicing some of the lab exercises.. and I've come across
an issue that I'm not sure if it's me making a mistake, or if it's a
problem with the boson simulator.

Here's the scenario.

I have 2 2950 switches; SWITCH_ONE and SWITCH_TWO for reference.

I have a crossover cable from fe0/12 on SWITCH_ONE to fe0/12 on
SWITCH_TWO for a trunk link.  I have the trunk working.  `sh vtp
status` shows it up and functioning fine.  SWITCH_ONE is the server,
SWITCH_TWO is the client.  (I've also tried this with one as server and
one transparent, with both transparent, and with both servers)

On SWITCH_ONE I've setup ports fe0/1 - fe0/5 as VLAN 30, and ports
fe0/6 - fe0/10 as VLAN 50.  When I do `sh vlan 30` it shows the
appropriate ports, and same for vlan 50.  However, whenever I go to
SWITCH_TWO it shows the same ports active in those vlans.  If I were to
add a machine to port fe0/3 on SWITCH_TWO to VLAN 50, it will also add
port fe0/3 on SWITCH_ONE into vlan 50, instead of leaving it in vlan
30.

Is this normal, or is this a glitch in the simulation software?  I
can't imagine that's the way it's supposed to work, but maybe it is, or
maybe I have something configured wrong.

I've been focusing on this issue for a day now trying to figure it
out.. but apparenlty I'm missing something or that dang boson simulator
is out to get me.
 
Please advise!

    That's a glitch.  Assigning a port on swith 2 to VLAN shouldn't change
any port settings on switch 1.

Well, it doesn't bring the interface up, it just shows it added to the
vlans.  Just to give you an idea, here's some output.

switch_ONE#sh vlan 150

VLAN Name                             Status    Ports
---- -------------------------------- ---------
-------------------------------
150  inside_machines                  active    Fa0/1, Fa0/10


switch_TWO#sh vlan 150

VLAN Name                             Status    Ports
---- -------------------------------- ---------
-------------------------------
150  inside_machines                  active    Fa0/1, Fa0/10

switch_ONE#conf t
switch_ONE(config)#int fa0/7
switch_ONE(config-if)#switchport access vlan 150
switch_ONE(config-if)#end
switch_ONE#sh vlan 150

VLAN Name                             Status    Ports
---- -------------------------------- ---------
-------------------------------
150  inside_machines                  active    Fa0/1, Fa0/7, Fa0/10

and then if I get on switch two, without doing anything except showing
the vlan, I get:

switch_TWO#sh vlan 150

VLAN Name                             Status    Ports
---- -------------------------------- ---------
-------------------------------
150  inside_machines                  active    Fa0/1, Fa0/7, Fa0/10

    Nope, that's not right.  Must be a software bug.

Re: VLAN Question.. STUMPED!
If you're using Netsim for CCNP it's probably a bug.  I haven't had
that particular error but I've had similar "am I stupid or what" type
errors just like that.  That's NOT the way it's supposed to work.
