ntp peer

Defines a Network Time Protocol (NTP) peer.

ntp peer <address> [version <number>] [prefer]
 
no ntp peer [<address>]
 

• address--hostname or IP address in dotted decimal form (a.b.c.d), of peer
• number--NTP version

Must be in configuration mode (config), which requires privileged-level access.

Available for use multiple times in the configuration.

number--4

Version number can be in the range 1 through 4.

Use the no form of the command with address to disable the peer relationship with the specified host.

Use the no form of the command without an argument to disable all NTP peer relationships.

Use the keyword prefer to indicate a preference (and reduce switching among servers).

NTP peers synchronize with each other and exchange NTP packets. All peripheral CNA modules are automatically synchronized with the management module.
