Can catalyst 4510 realize the following funtion ?

Dear ALL:

I have one question with the following situation:

There are 3 VLANs set up in Catalyst 4510. VLAN 1,2,3

There are security consideration with VLAN access:

The requirement is following:

VLAN 1 can visit VLAN 2; VLAN2 can not access VLAN 1

Can Catalyst realize this function, If yes, how?

Thanks for any help

Yes, this feature is named "access-list".


And seriously, if you have VLANs you need to communicate between, you have to use Layer3 functionality - create IP and/or IPX interfaces for VLANs and enable IP&IPX routing on the switch. And then you define, which IP Subnet can communicate to which, which traffic is allowed and which not, etc.

Good luck,

Even an older numbered access list would do. wrote:
