HULC LED PROCESS - 3750 High CPU



If you're looking at a switch and you see the HULC LED Process running high. The HULC LED process does some of the following tasks:


1. Check link status on every port
2. If the switch supports POE, it checks to see if there is a power device
3. Transceiver checks
4. Fan status updates
5. Set LED ports
6. Check on temperature status

Overall the HULC LED Process is a monitoring process running.

During looking into this I turned off all non-used ports since it checks the link status. Then I made sure the environment was good.
