In addition to the above post i would like to add that a Cisco switch can generate automatically three types of ICMP messages: Host Unreachable, Redirect and Mask Reply. An attacker can use these messages to aid in mapping a network.


Hence these commands are generally disabled on the interface as a security policy.
