Login overview
This chapter describes the available CLI login methods and their configuration procedures.
FIPS compliance
In Release 1118 and later versions, the device supports the FIPS mode that complies with NIST FIPS 140-2
requirements. Support for features, commands, and parameters might differ in FIPS mode and non-FIPS
mode. For more information about FIPS mode, see Security Configuration Guide.
Telnet and HTTP are not supported in FIPS mode.
Login methods at a glance
You can access the device only through the console port at the first login. After you log in to the device,
you can configure other login methods, including Telnet and SSH, for remote access.
