Hi
When I ping to one of the H3C comware switch in our network I don't get any reply .
all switches and my hosts are in default vlan .
I tried to debug on the destination H3c Comware switch to which I am pinging . I found below details which might be the reson I am not getting any reply from the switch.

Hi,
Check the route table. Do you have a route to this ip address (10.147.24.254)?

Hi,
Can you post the config from the switch you can't ping?

If I disable and enable any port in vlan 1 in the switch I get ping response for few hours and then again same issue starts.
