hello,<br>
<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<o:p></o:p></p>
