Extreme Switch x440 Configuration

[MohammedWaeez]

Hi Sir,
This is Mohammed Waeez from Banglore-India,
i got Extreme X440 Core switch and configured multiple VLANs.
and last 2 ports created as trunk ports.
problem is from truck port i am not able to ping any VLANs, and also not able Push the Internet connection,
from the Router. here we are using SONICWALL Router.

and i like to VLANs Should be private, here in this case i can't ping any other VLAN from another VLAN.
Now i am pinging any VLAN from any VLAN. i need to BLOCK.

please help me out,

Thanks and Regards
Mohammed Waeeez Ulla

By default, the vlan on a packet is "1" (native).
if your sonic router has no vlan on a trunk port, actually, it's the same thing when you untagged the vlan with number 1 (native mode)
and if you want to passed other vlan, or specific vlan you must tag
the port

Let's see then. Is the incoming Internet connected to the Sonicwall directly, or do you want to connect the Internet connection to some (untagged?) port on the X440 and then setup a VLAN trunk (tagged VLANs) from the X440 to the Sonicwall where both the Internet VLAN and the internal VLANs are trunked?

Internet --- Sonicwall ... X440 === internal VLANs

or

Internet ----------------- Port 1on X440(untagged)
Internal VLAN X----- Port 2 on X440(untagged)
Internal VLAN Y----- Port 3 on X440(untagged)
Internal VLAN Z----- Port 4 on X440 (untagged)
All VLANs to Sonic - Port 24 on X440 (tagged)

Let's take this one step at a time and describe the above the way you want it to be setup.

Also, how familiar are you with VLANs and routing in general?

We enabled the IP Forwarding,
But My issue is, i want to enable internet UPLINK from router to Trunk Port in x440 Switch,
and trunk ports to VLANS.

The first thing to try:

enable ipforwarding

Filtering between VLANs is in the thread above.

If you need more help, please specify one problem at a time and describe the setup in some more detail, please.
