is it because 5548 is an unmanaged switch? and so will allow all the data regardless of vlan

this is an existing scenario, I am just trying to understand how this is working

this is the connectivity

6248 (g23)-----(g48)5548(g43)----(x0)sonicwall

there are few virtual machines on 6248, and all other data switches are connected to 5548

There are no vlan's configured on 5548

Intervlan routing is being done by firewall.

So my question is how the vlan data is reaching to firewall when the port connected to 5548 is access port. this is really driving me crazy

This is the current situation

Now I am confused that how the traffic is going as both the ports connecting 6248 and 5448 are access ports

Vlan 60 and 90 routing is configured o firewall but how the vlan traffic is reaching there through access port.

below is config for 5448

qos basic

yes there is only one lan port on sonicwall which is conneted to 5548, is there anything else or any other way this could happen

there are servers on vlan 60 and 90 and hosts are connected to access switches connected to 5548, when I try to ping a machine on vlan 60 or 90 I am able to. and how all the hosts are accessing machines on vlan 60 and 90

My confusion here is how vlan traffic is going through 5548

I have just joined the company and I am also trying to understand the concept behind this type of configuration.

and I did not get any email

show tech does not work on 5548, is there any other output that you need

I Really apologize it is a 5448, will this change anything?

hi, i was wondering if this is due to the default route on 6248

ip route 0.0.0.0 0.0.0.0 192.168.1.x which is ip address of firewall lan interface, on which inter la routing for vlan 60 and 90 have been defined.

If this is so how is tis working?
