I'm adding a few point:-
Before update a new firmware , this switch detect a few port with 10mbps link...this is not suppose to be and should be 1Gbps..i'm checking physical cable looks good and also test to another switch are fine...Decide to update the firmware and found, the port with 10mbps before, become normal. Now im facing back the same issue but only port 3 become 10mpbs with flapping issue.
1. Boot :- B1.0.0.12 Software : 6.6.4.25
2. Change to another port no link flapping (OK)..with same cable, 1Gbps link physical status
3. Swap to other Port configuration: same as port 3
Kindly assist me on this.
Thank you.
