Setting up Management VLAN on 4506 and intervlan routing

[Andrew Schulz]

Hi,

I'm hoping someone can easily explain the best method for accomplishing setting up a Man VLAN. I would like for my workstation on VLAN 1 on an edge switch to be a member of the management vlan so I can access these devices.

Here is my setup:

I have a 7204VXR that does all our routing, we have a 4506 switch connected to the router, and then we have six 3560g edge switches.

I've created a new LAN on the 7204 for managment (VLAN 404)

***** 7204 *****

interface FastEthernet0/0

description Management LAN

no ip address

no ip unreachables

speed auto

duplex auto

no cdp enable

no mop enabled

!

interface FastEthernet0/0.1

encapsulation dot1Q 404

ip address 10.10.10.101 255.255.255.0

***** 4506 ******

interface Vlan404

ip address 10.10.10.102 255.255.255.0

interface GigabitEthernet2/17

switchport access vlan 404

switchport trunk encapsulation dot1q

switchport mode trunk

!

interface GigabitEthernet2/18

switchport access vlan 404

****************

Do I need to setup InterVLAN routing on the 4506? Will that mess with my 7204?

Thanks

You don't have to setup inter-vlan routing on the 4500 if all the vlans are currently routed off your 7200 router. A better question might be why you are not already using the 4500 for inter-vlan routing as you are currently having to share the fast ethernet bandwidth on the 7200 for your any subinterfaces you have on there.

But in your current setup what you would do is simply create a L3 vlan interface for vlan 404 on all your switches, assign an unused address from vlan 404 to each switch and then add this command to each switch -

ip default-gateway 10.10.10.101

Assuming each 3560 switch is connected to the 4500 you then simply need to make sure that they are connected by trunk links and that vlan 404 (as well as your existing vlans) are allowed on that trunk.

If you set it up this way you should be able to connect to any switch from any vlan.

Jon,

That is a better question and is one that I am considering. I do plan on eliminating the 7200 and using just the 4500 for routing.

Thanks for the feedback on the vlan 404 setup. I missed the edge switches in my setup.
