  • 1.  Aruba 3810m switches in stack

    Posted Dec 13, 2021 10:08 AM
    Hello guys,

    I have two (aruba-3810m-16sfp) switches stacked with ring topology member 1 status is commander and member 2 status is standby. I've configured the ports 1/16 and 2/16 with the same exact configuration. The problem is when connecting the end device to the port 2/16 the port comes up and the device becomes reachable which is fine. When connecting the same end device using the same DAC cable to the port 1/16 the port comes up but the device is unreachable ! .. any ideas ? I also checked the logs and nothing pointing to this issue.

    For the 3810M, the recommended topology for stacks of up to 5 members is a mesh; each stack member is connected to every other member to maximize reliability by providing multiple paths for rerouting traffic in the event of a link or chassis failure.

    The stacking feature for the 3800 or 3810M switches allows you to connect up to 10 switches and have them act as a single high-bandwidth switch for both data and management. One switch in the stack is designated as "Commander" and one switch is elected to be the "Standby". The other switches are designated "Member". The 3810M switches do not have a power switch. They will power on when either one or both power supplies are connected to an active AC power source.  My Sutter Health Online

    Aruba 3810M switches can be stacked using either a physical or virtual stacking method, depending on the specific model and firmware version. Physical stacking requires the use of dedicated stacking modules and stacking cables to connect the switches. With physical stacking, the switches operate as a single logical unit and share a single IP address, which simplifies network management. Virtual stacking, on the other hand, does not require any additional hardware and instead relies on the Virtual Switching Framework (VSF) technology built into the Aruba 3810M switches. With VSF, multiple switches can be configured to act as a single virtual switch, with a single management interface and control plane. To stack Aruba 3810M switches using either method, the switches must be running the appropriate firmware version that supports stacking. You will also need to configure the switches according to the appropriate stacking guidelines provided by Aruba. MyFortiva

    It sounds like the configuration on port 1/16 may not be identical to the configuration on port 2/16. Double-check that the configuration is exactly the same, including VLANs, access control lists, and any other settings that may be relevant to the connectivity of the end device. Another possibility is that there may be an issue with the physical port itself. Try swapping the cables between ports 1/16 and 2/16 and see if the problem follows the cable or stays with the port. If it stays with the port, it may be a hardware issue and you may need to replace the switch or the port module. If neither of those solutions work, try reaching out to Aruba support for further assistance in troubleshooting the issue. They may be able to provide additional guidance based on the specific logs and configuration details of your setup.
