VLAN configuration on x450e, routing issue

VLAN configuration on x450e, routing issue

I have a very basic network and am simply trying to get my VLANs to allow clients to their destination gateway which is the firewall.

Firewall > Core (x450e) > Access Switch 1 (x450e)
> Access Switch 2 (x450e)

On the Core switch, I have several VLAN's, Mgmt, Voice, Client, etc... The default route on all the switches point to the Management VLAN gateway on the Firewall. When on the management network I can ping between all switches as expected.

I then add a client in the client vlan and I am unable to get anywhere. A traceroute shows that it is by default trying to route via the management gateway. I don't believe I need to add routes for all the VLANs but am essentially just trying to make them access ports as I am familiar doing on Cisco switches.

Thanks for the help.

Hi all,

So on the switch where my client is attached, when I add

configure vlan Client ipaddress 10.10.0.6 255.255.255.0
enable ipforwarding vlan Client

From that switch, I can ping the client, however from other switches including core I cannot ping the client or the VLAN IP.

Per Ajo's request here is the output of the commands.

Also, make sure return traffic is allowed to your internal network.

Hi Andrew,

As Ajo pointed out, please check for the ipforwarding if it is enabled or not.

Below article might help you.

Also, from the firewall, make sure that there is a return route to all the other VLAN destination IP address.

Hope this helps!
