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?
