Concept Guide

• 0 directs Dell Networking OS to store the password as clear text. It is the default
encryption type when using the password option.
• 8 to indicate that a password encrypted using a sha256 hashing algorithm follows.
This encryption type is available with the sha256-password option only, and is the
default encryption type for this option.
• 7 to indicate that a password encrypted using a DES hashing algorithm follows. This
encryption type is available with the password option only.
• 5 to indicate that a password encrypted using an MD5 hashing algorithm follow. This
encryption type is available with the secret option only, and is the default encryption
type for this option.
password Enter a string up to 32 characters long.
privilege level Enter the keyword privilege then a number from zero (0) to 15.
secret Enter the keyword secret then the encryption type.
sha256-password Enter the keyword sha256-password then the encryption-type or the password.
Defaults The default encryption type for the password option is 0. The default encryption type for the secret option is
5. The default encryption type for sha256-password option is 8.

ICMP Commands
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 Networking OS mainly addresses the following ICMP
vulnerabilities:
• ICMP Mask Reply
• ICMP Timestamp Request
• ICMP Replies
• IP ID Values Randomness
Dell Networking OS can be congured to drop ICMP reply messages in the kernel. When the drop icmp feature is congured, the system
drops the ICMP reply messages on the front end and management interfaces. By default, the Dell Networking OS responds to all the ICMP
messages. The Dell Networking OS suppresses the following ICMPv4 and ICMPv6 message types:
