    [SOLVED] MAC address flappling on a Cisco Catalyst 2960-S

    I tried different bonding modes, but after every reboot I ended up with round-robin. After googling a bit I found this advisory from Hewlett Packard: https://support.hpe.com/hpsc/doc/public/display?docId=emr_na-c03001127 I looks like the modules must be loaded in a proper order, so I adapted the...
