  • 1.  Aruba2930F communication issue with firewall

    Posted Jul 14, 2023 09:56 AM

    Good afternoon people,
    Here in our company we use a SW Aruba 2930F in the CORE function, we had a recent problem with it that from one hour to another it stopped pinging our firewall, the communication with the entire internal network was working correctly but the ping of any machine or even the switch was not successful, we reviewed all the rules and routes and it did not work, we used the communication through a vlan10 used with untagged on the port that connected directly between the firewall and the switch, the communication only returned when we changed from untagged to tagged and created the vlan 10 also inside the firewall, has anyone gone through something similar? Could you tell me if the 2930F is suitable for use as a CORE, since we have a very large network and the table of declared networks is already full, thank you very much.

    2930F is not most seen in as a core in larger networks. You can check in the feature navigator what the scale is of the 2930F, and the number of MAC addresses is 32000. And it depends on what you feel is large if that is enough.

    Logging from your switch may provide more information what happened. Changing an uplink from untagged to tagged may reset all kinds of tables/processes and just for that reason restore operations.

    It may be best to work with your Aruba partner to select the proper switches in your network. Based on the information provided, we can just guess.

    Is there any command that I can check the amount of current tables? today we actually have several separate networks in vlans inside the equipment.

    Probably yes, but would not know the exact command. If you capture the output of 'show tech' it's likely that the data is in there somewhere.

    Recommended would be to do this with your Aruba partner or Aruba support, also to validate your design and confirm you have selected the right equipment (given the point that 2930F is normally not the first choice for a large network core).
