Getting Port aggregation to work between a DLINK and CISCO router.

I have two older switches and am trying to get a two port lag set up between the DLINK DGS 3650 (48 port) switch and and older CISCO 3550.  

I have tried using the following as reference material: http://support.dlink.co.id/docs/D-Link-Managed-Switches-Interoperating-with-Cisco-Switches.pdf


Cisco:  Port Gi 0/1-2 have been setup in trunking mode and have access to VLAN 1, VLAN 2, etc

DLINK:  Ports 47 and 48 are tagged ports and are grouped into a LAG.

Senario 1:  If I simple plug Gi 0/1-2 into 47 and 48, one port will come up and the other will be blocked, as one would expect

Senario 2:  If I place Gi 0/1-2 into a channel group they both get blocked on a protocol mismatch.

How do I start to trouble shoot this?

I'll answer my own question.  When you do something silly, man up and own it.

My LAG Modes on the DLINK and the CISCO where not compatabile.  Once I set them properlly, the LAG came up instantly (page 11-12).

Dlink: Passive (is the default used on all our dlinks)

Cisco: Active
