intermittent packet drop issue in lan network

[UMESH LONDHE]

we are facing intermittent packet drop issue in our lan network. we have three general vlan in our network as floor vise and have distribution switch per floor. at first floor we are facing the packet drop issue. while pinging to ip add in that network machine it pings but, it gets drops intermittent 

ping output like.... transmit failed general failure...

after some drops we get ping response again. can anybody help me out to resolve this issue.

Is it only to that machine you see drops ?

if you ping to another ip address on same switch do you see drops or just this machine ?

can you post the show interface x/x where the machine is connected

have you put a laptop on same port where machine is to see if issue is the same to rule out machine nic card being at fault

Hi mark,

as i mentioned, on distribution switch we have 15 access layer switches connected and packet drop issue is occurs randomly any   machine connected to that distribution switch now and then. as you suggested i have changed switchport, patch cord, and physical machine, also tried with loptop, but packet drops are still observed. 

Here is sh int of switch port

Hi

that switchport is clean but have you checked each ports from src to dst along the path , if that port or end device was at fault there would be crc and input errors etc on it to indicate an issue

you need to confirm each port the traffic passed through , have you checked the layer 2 trunk uplinks between src -dst

Check the cpu on the dist switch as well show proc cpu sorted make sure its not overloaded when the issue is occurring , show proc cpu history

when your on the dist switch do you have any intermittent responses between devices on the same switch
