ICMP Vulnerabilities
The internet control message protocol (ICMP) is a network-layer internet protocol that provides message packets to report
errors and other information regarding IP packet processing back to the source. Dell EMC Networking OS mainly addresses the
following ICMP vulnerabilities:
● ICMP Mask Reply
● ICMP Timestamp Request
● ICMP Replies
● IP ID Values Randomness
You can configure the Dell EMC Networking OS to drop ICMP reply messages. When you configure the drop icmp command,
the system drops the ICMP reply messages from the front end and management interfaces. By default, the Dell EMC
Networking OS responds to all the ICMP messages. You can configure the Dell EMC Networking OS to suppress the following
ICMPv4 and ICMPv6 message types:
