Configuring Username and Password Security
Saving Security Credentials in a Config File
Operating Notes
Caution â– When you first enter the include-credentials command to save the
additional security credentials to the running configuration, these settings
are moved from internal storage on the switch to the running-config file.
You are prompted by a warning message to perform a write memory
operation to save the security credentials to the startup configuration. The
message reminds you that if you do not save the current values of these
security settings from the running configuration, they will be lost the next
time you boot the switch and will revert to the values stored in the startup
configuration.
â– When you boot a switch with a startup configuration file that contains the
include-credentials command, any security credentials that are stored in
internal flash memory are ignored and erased. The switch will load only
the security settings in the startup configuration file.
â– Security settings are no longer automatically saved internally in flash
memory and loaded with the startup configuration when a switch boots
up. The configuration of all security credentials requires that you use the
write memory command to save them in the startup configuration in order
for them to not be lost when you log off. A warning message reminds you
to permanently save a security setting.
â– After you enter the include-credentials command, the currently configured
manager and operator usernames and passwords, RADIUS shared secret
keys, SNMP and 802.1X authenticator (port-access) security credentials,
and SSH client public-keys are saved in the running configuration.
Use the no include-credentials command to disable the display and copying
of these security parameters from the running configuration (using the
show running-config and copy running-config commands), without disabling
the configured security settings on the switch.
After you enter the include-credentials command, you can toggle between
the non-display and display of security credentials in show and copy
command output by alternately entering the no include-credentials and
include-credentials commands.
â– After you permanently save security configurations to the current startup-
config file using the write memory command, you can view and manage
security settings with the following commands:
• show config: Displays the configuration settings in the current startup-
config file.
