I use EDP (that works fine), EAPS, ELSM. That's all.<br>

Just L2 switching, mirroring, EAPS, ELSM, EDP, IGMP Snooping...<br>

There were 2 entries in config :<br>
configure ip-security dhcp-snooping information circuit-id
vlan-information 101 vlan test1<br>
configure ip-security dhcp-snooping information circuit-id
vlan-information 121 vlan test2<br>
<br>
but I have them removed and it didn't cause hardware table to learn
anything...<br>
<br>
I have ~100Mbit/s of unknow unicast traffic at ~4.5G of internet
traffic... that's a lot.<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>
