C3750G - Notconnected2

betodru01
Level 1
Level 1

Dear,

At some time, I'm having trouble with my 4 port switch-core. They do trunk with the distribution, my scenario is L2 switches stacked with two colors on stack wise. The problem is that my core is one with 4 doors notconnected and core 2 are up. I'm using port-channel with link aggregation eliminating spanning three. Already tested and cables are ok. Ja jabbed devices directly on the core clearing all configuration but not change. I ask:

Does my doors burned or some setting may have given this problem?

I thank you.

Hi Herbert,

Could you kindly share the configuration and outputs from your devices?

Outputs required;

show tech/show running-config

show port-channel summary

show interface X switchport

show logging.

Hi Herbert,

I see couple of ports are suspended :

9      Po9(SU)          -        Gi1/0/9(D)  Gi2/0/9(P)

10     Po10(SU)         -        Gi1/0/10(D) Gi2/0/10(P)

11     Po11(SU)         -        Gi1/0/11(D) Gi2/0/11(P)

12     Po12(SU)         -        Gi1/0/12(D) Gi2/0/12(P)

13     Po13(SU)         -        Gi1/0/13(P) Gi2/0/13(P)

Hence kindly check the other end and make sure the config is same at both the ends of the ports.

Regards

I removed the interface of the 3750G channel group and then put a laptop straight to the door and neither circuit runs, you should probably be the same physical defect.
