  • 1.  FN-2021-460 - Base MAC address is modified after upgrading to SLXOS 20.1.1 or higher

    Posted 04-13-2021 20:24

    Summary

    After upgrading to SLXOS 20.1.1 or higher, the starting MAC address of the system is modified by two digits.

     

    Impact

    The MAC address modification may cause issues if there are permit or deny ACL’s using the MAC address of the device, specifically when a peer is expecting the prior MAC address (from 18r.x software version), and a different MAC address is now seen (with 20.x.x software version).

    Workaround
