Re: ACL
If you make an ACL you will be blocking traffik based on originor destiantion. And that blocking is not based on a session.
You can make acl's that the 3 other vlans can not acces each other but they can allways access the management vlan.
Good luck

Re: ACL
Thank you for your response, actualy I used 5412zl core switch, and I tried to solve this by creating an ACL. but the result is each of vlan 1, 2 and 3 can't access each other and also can't access admin vlan which this is I want.
but the bad thing I got it is that admin vlan also can't access the other vlan, but the required result is admin vlan can access any thing.

Solutionon vlan 1's ACL, you'd include a line such as:
permit tcp
This will permit replies to established sessions/conversations from vlan 1 (source) back to the admin vlan (destination). Vlan 1 users will not be able to originate new TCP sessions but only reply to sessions allowed in from Admin.
You would do the same for vlans 2 & 3.
Note that ACL's are NOT a replacement for a stateful firewall. ACL's are best used to take load off of a firewall.
