    Hi All,

    Im just new a in Aruba. I have a 4 switches ex names (A,B,C,D) Aruba1930-48G (JL686A) will hold the traffic from end points (PCs, CAM ,...) with untagged Vlans 3,5,20,150 per every interface.
    I set Vlan 5 on those switchs to to connect each other and to Hub Switch. ex( Vlan 5 : 10.5.0.4 /27 for A switch)  and gateway 10.5.0.1 for Hub Sw(X).


    Those 4 SWs connect to 2530-24G (J9776A) switch ex name (X) with a Tagged interface with all vlans.
    Also this Hub switch(X) connect to a router on port-1 with untagged vlan 16 and with default-gateway 192.168.1.1.

    The issue now  for example:
    1- From A switch I can reach vlan 16 ip (192.168.1.50) which is on X Hub switch, but can't reach 192.168.1.1 router.
    2- From a PC (with gateway to Switch (x) ) on Vlan 3 I can reach the ip on switch(X) to other Vlan 16 (192.168.1.50) but also still can't reach 192.168.1.1.
    3- from the same Vlan 20 Pc I can't reach

    For Routing I already make 0.0.0.0/0 to 10.5.0.1 on SW (A), and for SW (X) the router 192.168.1.1 is the gateway.

    Do you have routes for both directions to 192.168.1.1, and back to 10.3.0.4 ?

    VLAN 16 shows as down, can you check to see if VLAN 16 is tagged on both sides of SwitchA and SwitchX.

    The 2530 does not have L3 routing capabilities. I believe the 1930 can do L3 routing, as well your router can probably do that. That answer the question 2; and 3 (although I don't see VLAN20 in the diagram).

    On VLAN16 the thing is different, if you can reach from the 1930 the .50 on the 2530 but not the .1 on the router, there probably is an issue with the port configurations between the 2530 and the router. Are you using VLAN tags? Or the 'native (untagged)' VLAN on those ports?
