before port 1 bouncing or changinng power inline config :

gggSW1#sh cable tdr interface Gi 0/1
TDR test last run on: July 01 13:34:35

Interface Speed Local pair Pair length Remote pair Pair status
--------- ----- ---------- ------------------ ----------- --------------------
Gi0/1 auto Pair A N/A N/A Normal
Pair B 10 +/- 10 meters N/A Open
Pair C 8 +/- 10 meters N/A Open
Pair D 9 +/- 10 meters N/A Open

after changing  the power inline  config  or after just  bouncing , the access point connected port comes up for 20 mins and  again it goes  down.

gggSW1#sh cable tdr interface Gi 0/1

Hi All . 

@Leo Laohoo @balaji.bandi @paul driver .

I have  the moved  the access point  to  port  2  on  the  switch , now  everything looks good.

Thanks for the quick inputs. You guys are really great in helping  the community.

Nice to know and glad all working, as we suspected some physical issue was around, thanks for the confirming and good stuff !
