I have a cisco 3560 as my core agragate switch in my network. Everything is running fine currently until I tried adding a second port on one of my DLSAMs to add funcionality to another network. I currently have another similar device running two seperate ethernet ports on two seperate VLANs that are managed in the software of the DSLAM to determine which network a particular DSL port talks on. This second one however is giving me pletny of problems.
i have configured the switch port to the VLAN I require, I am able to plug in a laptop and talk on the network correctly (pull DHCP and get on the internet on the correct network). But when I try plugging up my DSLAM the port stays orange. If I leave the VLAN set to the default (vlan1) it will turn green but as soon as I change the VLAN it turns orange again. The settings are the same on both DLSAMS as far as port and VLAN configuration goes. The port is linking up correctly at 100 Full on both sides.
I will add more information as I continue to troubleshoot this. But for now hopefully this should give a brief explanation of my problem in case I am just overlooking something very simple.
