CLOCK SYNCHRONIZE
The clock synchronize command establishes how, from where, and how often the 
chassis should synchronize its time with an external source.
There are three elements to the specification: 
• Protocol 
This is the protocol to be used. Most common is the NTP protocol. Another 
option is the more basic rdate. It is also possible to synchronize the system 
time from the RTC.
• Server
The address of the server that is used as the external time source. This is 
valid only for NTP and RDATE protocols.
• Rate 
The rate at which the synchronization should be performed. Typically, the 
settings are in the multi-hour range. The default value for the rate is every 12 
hours.
EXAMPLE
ALU(config)# clock synchronize using ntp server 10.91.2.87 
every 120 minutes
This command has no output. To verify the settings, use the ‘show clock’ 
command described in this section.
Command (in CM) Description
clock synchronize [{using {ntp 
server <name> [vrf <vrf-name>] 
|rdate server <name>|rtc} 
[every <1-1440> minutes]
This command establishes how the 
chassis should synchronize its time with 
an external source.
Note: Currently ‘rdate’ is not 
supported.
no clock synchronize This command unconfigures the clock 
synchronization.
