                    <br>
                    At the moment I have 3 sites with x650 switch.<br>
                    All of them running 15.3.1.4 v1531b4-patch1-3<br>
                    <br>
                    In main site, the problem is that hardware fdb table
                    is not used !?<br>
                    Hardware-learned entries:<br>
                    MAC               VlanId    Flags Port  HIT    VPLS<br>
                    ===================================================<br>

                    Num of msgs from FDB :              2258820<br>
                    <br>
                    on the other sites, this table contains entries
                    equal to what's on show fdb stats.<br>
                    I was trying to compare configs, there were some
                    dhcp-snooping entries for 2 vlans, but removing them
                    didn't help out (or maybe it requires reload ?)<br>
                    <br>
                    My main problem is that at the level of ~16k mac
                    addresses I have a lot of unknow-unicast traffic
                    that shouldn't be there.<br>
                    <br>
                    oh - the only function that is in central site is -
                    mirroring.<br>
                    <br>
                    Anyone knows how to turn on hardware fdb table ?<br>
