I think you have these references wrong?<br>
<br>
Both of these use the same backend code and neither touch the macaddress table. I suspect you mean:<br>
<br>
<a href="http://git.io/dmWA6g" target="_blank">http://git.io/dmWA6g</a> and <a href="http://git.io/7ZPmUw" target="_blank">http://git.io/7ZPmUw</a> updates switchports table to ge-0/0/0<br>
<br>
Where as:<br>
<br>
updates macaddress table discovers macaddresses at ge0/0/0.0?<br>
<br>
<br>
Now, looking at the SNMP dump you posted previously (<a href="https://gist.github.com/pdxmaverick/6597601" target="_blank">https://gist.github.com/<u></u>pdxmaverick/6597601</a>), it looks like Juniper are reporting ifDescriptions (<a href="http://switchport.name" target="_blank">switchport.name</a>) such as:<br>
<br>
.1.3.6.1.2.1.2.2.1.2.602 = STRING: "ge-0/0/2"<br>
.1.3.6.1.2.1.2.2.1.2.603 = STRING: "ge-0/0/2.0"<br>
<br>
and ifNames (switchport.ifName) as:<br>
<br>
.1.3.6.1.2.1.31.1.1.1.1.602 = STRING: "ge-0/0/2"<br>
.1.3.6.1.2.1.31.1.1.1.1.603 = STRING: "ge-0/0/2.0"<br>
<br>
<br>
It's not important that these are the same but it is important that these appear to be two references to the same port?<br>
<br>
I suspect that when adding these switches in IXP Manager you're also looking at a port entry for ge-0/0/2 and ge-0/0/2.0?<span class="HOEnZb"><font color="#888888"><br>

<br>
PS: if anyone is wondering why ifDesc is confusingly named 'name' in the switchport database, it's an unfortunate legacy that would be a boat load of work to change.<div class="HOEnZb"><div class="h5"><br>
