VLAN Help

Plzzzz help with configuration....

I have L3 switch 4506 and we need to create 5 VLANS on it.

VLAN Admin

VLAN Finance

VLAN Server

VLAN User

VLAN Management

Our requirement is -

<1> Finance-VLAN to communicate with Server-VLAN only

<2> Management-VLAN to communicate with Admin-VLAN

<3> Other VLAN's can communicate with each other.

Re: VLAN Help

If u create L3 VLANs with separate subnet assigned to each VLAN, u can restrict communication by applying ACLs to each L3 VLAn .

Re: VLAN Help

Can you let me know the steps how to restrict communication between VLANS.

We want oto use OSPF as the routing protocol, so what config is required for this..

Re: VLAN Help

You can try this:

config t

int vlan 10

description Admin VLAN

ip address 192.168.10.1 255.255.255.0

int vlan 20

description Finance VLAN

ip address 192.168.20.1 255.255.255.0

int vlan 30

description Server VLAN

ip address 192.168.30.1 255.255.255.0

int vlan 40

description User VLAN

ip address 192.168.40.1 255.255.255.0

int vlan 50

description Management VLAN

ip address 192.168.50.1 255.255.255.0

In the switchports of the 4506, use:

int fa0/1 (whatever port)

description Server Only

switchport mode access

switchport access vlan 20

switchport access vlan 30

int fa0/2

description Management

switchport mode access

switchport access vlan 10

switchport access vlan 50

inf fa0/3

description Other VLANS

switchport mode access

switchport access vlan 40

Make sure that you assign workstations/servers to the right switchport, and check IP ROUTE is correct.

hth,
