Difference between ColdStart and WarmStart trap in Network Management

In network management, Trap  is a message sent by agent to manager. Two broad categories of traps are generic and specific, cold start and warm start being the generic traps. Here is the difference between two:

Cold Start: This trap indicates that sending device is re-initializing itself such that the agent’s configuration may be altered.

Warm Start: This trap indicates that sending device is re-initializing itself such that the agent’s configuration is not altered.

Note that cold start & warm start traps have nothing to do with self reboot or hard reboot of network element aka agent aka sending device. Only difference between the two is the change in agent’s configuration with cold start trap.
