Brocade Communications Systems FastIron Administration Manual page 47

The burst option sends a burst of packets to the peer at each polling interval.
NOTE
When the NTP server/peer is configured, the master command is not configured; on configuring the
clock set command the system clock is not synchronized. When the master command is configured,
on configuring the clock set command the system clock is synchronized and the reference time will be
the local clock.
To have active peers at both the ends, you need to disable NTP, configure the peers and enable the
NTP using the no disable command.
Configuring NTP on an interface
To configure the NTP interface context, use the ntp-interface command. The broadcast server or client
is configured on selected interfaces. To remove the NTP broadcast configurations on the specified
interface, use the no form of this command.
NOTE
The ntp-interface command is a mode change command, and will not be included in to the show run
output unless there is configuration below that interface.
Brocade(config-ntp)# ntp-interface ethernet 2/13
Brocade(config-ntp-if-e1000-2/13)# exit
Brocade(config-ntp)# ntp-interface management 1
Brocade(config-ntp-mgmt-1)# exit
Brocade(config-ntp)# ntp-interface ve 100
Brocade(config-ntp-ve-100)#
Syntax: [no] ntp-interface { management 1 | ethernet port | ve id }
The management 1 parameter is the management port 1.
The ethernet port parameter specifies the ethernet port number. Specify the port parameter in the
format stack-unit/slotnum/portnum.
The ve id parameter specifies the virtual port number.
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 the 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. The 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 the NTP broadcast server packets are not sent. To disable this
capability, use the no form of this command.
