              <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>
              Hardware-learned In-use count: 0<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>
              <br>
              Regards,<br>
              Marcin<br>
