Chapter 1 Setting Up the ACE
Detailed Steps
Command
Step 1
config
Example:
ACE_1/Admin# config
ACE_1/Admin(config)#
Step 2
ntp peer ip_address [prefer]
Example:
ACE_1/Admin(config)# ntp peer 192.168.10.0
no ntp peer ip_address
Example:
ACE_1/Admin(config)# no ntp peer
192.168.10.0
Step 3
ntp server ip_address [prefer]
Example:
ACE_1/Admin(config)# ntp server
192.168.10.10
no ntp server ip_address
Example:
ACE_1/Admin(config)# no ntp server
192.168.10.10
Step 4
do copy running-config startup-config
Example:
ACE_1/Admin(config)# do copy
running-config startup-config
Examples
For example, to specify multiple NTP server IP addresses and identify a preferred server, enter:
host1/Admin(config)# ntp server 192.168.10.10 prefer
host1/Admin(config)# ntp server 192.168.4.143
host1/Admin(config)# ntp server 192.168.5.10
OL-20823-01
Purpose
Enters global configuration mode.
Configure the ACE system clock to synchronize a peer (or to be
synchronized by a peer).
The keywords, arguments, and options are:
ip_address—IP address of the peer providing or being
•
provided by the clock synchronization.
prefer—(Optional) Makes this peer the preferred peer that
•
provides synchronization. Using the prefer keyword
reduces switching back and forth between peers.
(Optional) Remove an NTP peer or server from the
configuration.
Configure the ACE system clock to be synchronized by a time
server.
The keywords, arguments, and options are:
ip_address—IP address of the time server that provides the
•
clock synchronization.
prefer—(Optional) Makes this server the preferred server
•
that provides synchronization. The prefer keyword sets this
NTP server as the preferred server if multiple servers have
similar accuracy. NTP usesan algorithm to determine which
server is the most accurate and synchronizes to that one. If
servers have similar accuracy, then the prefer keyword
specifies which server to use.
(Optional) Remove an NTP peer or server from the
configuration.
(Optional) Copies the running configuration to the startup
configuration.
