Brocade FastIron Ethernet Switch Administration Guide - Manual (Page 48)

NOTE
If the peer is a member of symmetric passive association, then configuring the peer command will fail.
Brocade(config-ntp)# peer 1.2.3.4 key 1234
Syntax: [no] peer { ipv4-address | ipv6-address } [ version num [ key key-id ] [ minpoll interval ] [
maxpoll interval ] [ burst ]
The ipv4-address or ipv6-address parameter is the IP address of the peer providing the clock
synchronization.
The version num option defines the Network Time Protocol (NTP) version number. Valid values are 3
and 4. If this option is not specified, then the default is 4.
The key key-id option defines the authentication key. By default, no authentication key is configured.
The minpoll interval option is the shortest polling interval. The range is from 4 through 17. Default is 6.
The interval argument is power of 2 (4=16s, 5=32s, 6=64s, 7=128s, 8=256s, 9=512s, and so on).
The maxpoll interval option is the longest polling interval. The range is 4 through 17. Default is 10. The
interval argument is calculated by the power of 2 (4=16s, 5=32s, 6=64s, 7=128s, 8=256s, 9=512s, and
so on).
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.
