Cisco 3560 and 4500 with code 3.6.6.E has two open UDP Ports (1025/1031)

Hi,

Does anyone know why these two UDP Ports are open on this level of code? I've done a bit of researching and I cannot find any documentation listing the feature that is using these ports. "Show ip sockets" reveals they're open. 

Thanks

Hi

i don't see 1031 open on any of mine running same code  , but 1025 is and i believe its used for MS traffic , its a 3650 yes as its ios-xe 3560 is ios based only

see another post on it depending on the general application in use in the network , maybe a wireshark would help see whats using it and for what
