communication between VLANs

  • 1.  communication between VLANs

    Posted May 12, 2020 10:43 AM

    Hello everyone


    I have a swicht 2930F where I have 6 VLANs created, the main one is VLAN 1.


    from VLAN 3 I can ping the VLAN 1 teams but from VLAN 1 I cannot ping the VLAN 3 teams and so in all VLANs I can ping the VLAN 1 teams but from the VLAN 1 I cannot ping the computers on the other VLANs.


    I am setting up a network sniffer and I need to capture the data but I do not know if for this detail I am not seeing the traffic between the VLANs

    Share your switch configuration and I will see if I spot anything, but it sounds like you are trying to use the switch as a router?

    We suppose you (a) assigned an IP address to each of your VLANs defined on your Aruba 2930F (let we suppose you assigned to VLAN 1, to VLAN 2, to VLAN 3...and so on up to to VLAN 6) and (b) you enabled IP routing (see ip routing command).


    If you did that each message of any host of a particular VLAN (say Host A of VLAN 1) - if the host is properly addresses (with an IP Address set within the subnet and Default Gateway set to - will be correctly routed to any other host of another VLAN (say Host B of VLAN 3, example of VLAN 3 host: 10.0.3.x/24 with D.G and Host B with IP address 10.0.3.y and Default Gateway Clearly you must deal with proper settings IF OS Firewalls interfere with ICMP Ping or other protocols/ports.


    Can you report about that? ...that's the essential minimum to have inter-VLANs communication.
