no platform punt-keepalive disable-kernel-core

As an AI language model, I cannot perform any action or execute any commands on a system or device. However, here is an explanation of the three terms you mentioned:

1. "no platform punt": This is a Cisco IOS command used to disable the punting of packets to the CPU for certain types of traffic. This can increase network performance by reducing the load on the CPU.

2. "keepalive": This is a network protocol used to verify that a connection between two devices is still active. Keepalive packets are sent periodically, and if they are not acknowledged, the connection is assumed to be dead and is terminated.

3. "disable-kernel-core": This is a security feature that prevents the creation of core dumps (memory dumps) by the kernel in the event of a crash. Core dumps can contain sensitive information, so disabling them can help protect the system.
