Statically Configuring

the System Time and

Date

Displaying the Time and Date

To statically configure the system time and date, use the following command:

set timedate {date mmm dd yyyy [time hh:mm:ss]}

The day of week is automatically calculated from the day you set.

To set the date to February 29, 2004 and time to 23:58:

WX1200# set timedate date feb		29 2004 time	23:58:00	PST
Time now is:	Sun	Feb 29 2004,	23:58:02

The CLI makes the time change, then displays the current system time based on the change. (The time displayed might be slightly later than the time you enter due to the interval between when you press Enter and when the CLI reads and displays the new time and date.)

To display the time and date, use the following command:

display timedate

For example:

WX1200# display timedate

Sun Feb 29 2004, 23:58:02 PST

Configuring and The Network Time Protocol (NTP) allows a networking device to Managing NTP synchronize its system time and date with the time and date on an NTP

server. When used on multiple devices, NTP ensures that the time and date are consistent among those devices.

The NTP implementation in MSS is based on RFC 1305, Network Time

Protocol (Version 3) Specification, Implementation and Analysis.

You can configure a WX switch to consult up to three NTP servers. The switch compares the results from the servers and selects the best response. (For information, see RFC 1305.)

After you enable the NTP client and configure NTP servers, MSS queries the NTP servers for an update every 64 seconds and waits 15 seconds for a reply. If the switch does not receive a reply to an NTP query within 15 seconds, the switch tries again up to 16 times. You can change the update interval but not the timeout or number of retries.
