Cisco 5508 trunk port configuration

[Clay Plaga]

I am trying to configure a Cisco 5508 on my test network. Does the connection from my switch to port 1 on the 5508 need to be a trunk port?

Thanks.

- Depends on what you mean for port 1 on the 5508 , I would suggest to start with a more broadened overview and or this document :

Thank you for the help. The 5508 has 8 SFP distribution ports. I am connected to distribution port 1 through a SFP cat5 adapter. The adapter is working because when I directly connect a laptop to the SFP cat5 adapter, I get access to the controller. Port 1 is configured with 192.168.5.250. The laptop has an IP of 192.168.5.249. So I am wondering does the connection between my switch and port 1 of the controller need to be a trunk or access. The port on my switch, fa0/22 that is connected to distribution port 1 on the controller is configured as a trunk and I am getting no light, no connection. I tried configuring the switchport fa0/22 as an access port and it did not work. 

Thank you.

 - Check the switch-logs when the intended connection is made, preferably check connect a serial console to the 5508, and observe for messages on the console too, if any. I think it could be either trunk or access, if no different wlans/vlans are needed for the moment. You may of course toggle and check if that makes any difference.

I am connected to the controller with a console connection as well. I will try what you suggest. Is there a command I need to use to see the logging?

Thank you. 

[marce1000]

 - Not on the controller, the console will log all events. On the switch you usually need show logging.

I ran show logging on CLI on console. This is the output.

          - Check the switch logs too

Okay thanks. I have to run out. I'll check it out later.

I think the issue is that you are connecting a Gigabit Ethernet port to a fast Ethernet port. The 5508 port are 1gig only and can’t negotiate down to 100mbps.

UPDATE

I connected the 5508 to the gi0/1 interface on the switch module(there's only one), and I'm up and running!  I see why you're a hall of famer. Thanks again.

Thank you bro, you really helped me!

[Scott Fella]

Nope, the 5508 is gigabit Ethernet only. The 2504 is 10/100/1000. You will need to have a port that supports gigabit.

[Scott Fella]

Well glad you at least found a port to use and have it working.
