<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hello Marcin,
<div><br>
</div>
<div>The reason why it made sense to me is the need for more bandwidth for the subscriber circuits. So the only solution would be to look at an upgrade of the platform? Or in my specific case i guess i could split the 200 vlan's on two ports - 100 each, it
should get me more bandwidth - and not use link-group?</div>
<div>
<div><br>
</div>
<div>Would it make any difference if i would have the constituent ports of the link-group on different MIC cards in the SE-100?</div>
<div><br>
</div>
<div>Thanks!</div>

In my opinion - access mode on SE100 makes no sense...<br>
SmartEdge in this mode sends traffic only via signle link.<br>
It makes sense when you have 2 linecards and link-group spans between linecards.<br>
Than, in case of linecard crash traffic continues to flow.<br>
<br>
Other modes - dot1q - will do load sharing, but you can't have subscriber circuits on them (pppoe, clips).<br>

I configured an access link-group between a SE-100 and a Brocade MLX. The problem i face is that traffic from the Brocade towards the Redback is being split among the links but the other way around, the Redback sends traffic using just one link. I have set
the link-group both with LACP and static but the result was the same.<br>
I have tried both round-robin / interface-based, created the link-group both as access and access-economical, had the link-group both static and lacp - same result was reached.
<br>
I was wondering if this is a limitation of the SE-100 unit or i am missing something?<br>

Just as a note, non-access link-groups btw the Brocade MLX and the Redback unit work fine.<br>
