Vlan Configuration between Cisco C3560X and Sonicwall E5500 ?

vinish milton · ‎08-16-2013

Hi,

I am new the Vlan configuration. Recently I have purchase cisco L3. I want my sonicwall to be the primary L3 routing. We have around 2000 users. Users need to be get ip from sonicwall(DHCP).

My ip plan is as below.

Sonicwall Ip : 10.10.20.1

Cisco 3560 Management Vlan1 ip : 10.10.20.2

Vlan 10 : 10.10.0.1/255.255.252.0

Vlan 20 : 10.20.0.1/255.255.254.0

Vlan 30 : 10.30.0.1/255.255.254.0

vlan 40 : 10.40.0.1/255.255.252.0

Vlan 50 : 10.50.0.1/255.255.255.254.0

Vlan 60 10.60.0.1/255.255.255.0

Vlan 70 ip : 10.70.0.1/255.255.254.0

Vlan 80 : 10.80.0.1/255.255.254.0

All Vlan port will connected to respective building L2 switch( like Vlan 10 Port 1 connected to Academic building cisco L2 switch, Vlan 20 port 2 connected to mechanical building L2 et.,) I have 8 access points. It connected to L2 switches. Access point controller connected to L3 switch. User will be get ip from sonicwall.

How can I configure L3 and L2 switch? Pl guide.

Thanks.

You'll need to have routing enabled to route between vlans with the "ip routing" command. (It may be on by default on the 3560X.) You'll need to create L3 svis to attach to the vlans on the switch after you create the vlans:

vlan 10

vlan 20

etc.

int vlan 10

ip address 10.10.0.1 255.255.252.0

no shut

int

switchport mode access

switchport access vlan 10

You can do this for all of the vlans. To get dhcp, let's assume the main dhcp server is on vlan 10. On every other vlan interface you would add "ip helper-address ". For example, if you dhcp server was 10.10.0.100, then on vlan 20, you would have a scope on the dhcp server for the 10.20.0.0 subnet. Then on the svi, you would add:

int vlan 20

ip helper-address 10.10.0.100

Technically, you won't need to do anything with vlans on the sonicwall. You just need to route back to the 3560 for all of your subnets, and you can do that with a static route or ospf/rip if the Sonicwall supports that. I would recommend ospf if you have the option....

HTH,

Thanks your reply John,

As per the Sonicwall guidence i have done the below configuration at L3, now all vlan is working and users get respetive ips, i have connected Access point controler to port no 15. The problem is cant communication between access point controler and access point(except Admin building Access point, which is connected to vlan 30). Kindly guide me.

i did'not see any vlan in your config

you must create all vlan

interface valn 10

IP address ?

no shut

intterface vlan 20

ip address ?

no shut

interface vlan 30

ip address ?

no shut

also check from

sh ip int brief

all vlan exist are up if its not up that means its down .

John Blakley · ‎08-16-2013

In order to route out of the vlan (port 15 being an access port), you'll need to have an svi attached to the vlan. Create a vlan 30 interface (int vlan 30) and assign the respective address to it. Make sure that you change the devices on that vlan to use the interface vlan 30's ip address as their default gateway.

HTH,
John

Now Keep IN mind

all respective clients that belong vlan

1,10,20,30,40,50,60.70,80

gateway will be their respective vlan that u have created for each client on l3 Switch

e.g

vlan 10 client

gateway will be L3 Switch vlan IP

10.10.0.1

vlan 20 cleint

gateway will be l3 switch vlan ip

10.20.0.1

etc... like dat

Adding

L2 Switches if u want to assing interface to vlan

just go under that interface

interface fastethernet 0/1

switchport modes access

switchport access vlan x (which ever u want to assign)

Wrong forum, post in "LAN and switching". You can move your posting using the Actions panel on the right.

vinish milton · ‎08-18-2013

i have move this forum to Lan & switching.

Does anyone have any advice on how to get my VLANs connected to the internet?

jawad-mukhtar · ‎08-19-2013

vinish u have not provided feedback of above configuration which i provided.

for internet to work u will have to add default route in your 3560

ip route 0.0.0.0 0.0.0.0 (next ho gateway Internet Device IP)
