Disabling NTP
Disabling NTP
To disable the NTP server and client mode, use the disable command in NTP configuration mode.
Disabling the NTP server or client mode will not remove the configurations.
Brocade(config-ntp)# disable
Syntax: [no] disable [ serve ]
If the serve keyword is specified, then NTP will not serve the time to downstream devices. The serve
keyword disables the NTP server mode functionalities. If the serve keyword is not specified, then both
NTP client mode and NTP server mode functionalities are disabled.
Use the no form of the command to enable NTP client and server mode. To enable the client mode,
use the no disable command. To enable the client and server mode, use the no disable serve
command. The no disable command enables both client and server, if the client is already enabled
and server is disabled at that time "no disable server " enables the server.
NOTE
The disable command disables the NTP server and client mode; it does not remove the NTP
configuration.
Enabling NTP authentication
To enable Network Time Protocol (NTP) strict authentication, use the authenticate command. To
disable the function, use the no form of this command.
By default, authentication is disabled.
Brocade(config-ntp)# [no] authenticate
Syntax: [no] authenticate
Defining an authentication key
To define an authentication key for Network Time Protocol (NTP), use the authentication-key
command. To remove the authentication key for NTP, use the no form of this command.
By default, authentication keys are not configured.
Brocade(config-ntp)# authentication-key key-id 1 md5 moof
Syntax: [no] authentication-key key-id [ md5 | sha1 ] key-string
The valid key-id parameter is 1 to 65535.
MD5 is the message authentication support that is provided using the Message Digest 5 Algorithm.
The sha1 keyword specifies that the SHA1 keyed hash algorithm is used for NTP authentication.
NOTE
If JITC is enabled, only the sha1 option is available.
The key-string option is the value of the MD5 or SHA1 key. The maximum length of the key string may
be defined up to 16 characters. Up to 32 keys may be defined.
