Configuring NTP
7
Configuring the broadcast client
To configure a device to receive Network Time Protocol (NTP) broadcast messages on a specified
interface, use the broadcast client command. NTP broadcast client can be enabled on maximum of
16 ethernet interfaces. If the interface is operationally down or NTP is disabled, then NTP
broadcast server packets are not received. To disable this capability, use the no form of this
command.
Brocade(config-ntp mgmt-1)# broadcast client
Syntax: [no] broadcast client
Configuring the broadcast destination
To configure the options for broadcasting Network Time Protocol (NTP) traffic, use the ntp
broadcast destination command. NTP broadcast server can be enabled on maximum 16 ethernet
interfaces and four subnet addresses per interface. If the interface is operationally down or there is
no ip address configured for the subnet address, then NTP broadcast server packets are not sent.
To disable this capability, use the no form of this command.
NOTE
This command is not effective, if the NTP server is disabled.
Brocade(config)#int m1
Brocade(config-if-mgmt-1)#ip address 10.20.99.173/24
Brocade(config-if-mgmt-1)#ntp
Brocade(config-ntp)#ntp-interface m1
Brocade(config-ntp -mgmt-1)# broadcast destination 10.20.99.0 key 2
Syntax: [no] broadcast destination ip-address [key key-id] [version 3|4]
The IP-address parameter is the IPv4 subnet address of the device to send NTP broadcast
messages to.
The key key id option defines the authentication key. By default, no authentication key is
configured.
The version 3|4 option defines the Network Time Protocol (NTP) version number. If this option is
not specified, then it defaults to 4.
Disabling NTP
To disable the NTP server and client, use the disable command. Disabling the NTP server or client
mode will not remove the configurations. To enable receipt of NTP packets, use the no form of this
command.
Brocade(config-ntp)# disable
Syntax: [no] disable [serve]
If the [serve] keyword is specified, then NTP will not serve the time to downstream devices. This
keyword disables the NTP server mode functionalities.
If this keyword is not specified, then both NTP client mode and NTP server mode functionalities will
be disabled
