Time Protocols
SNTP: Viewing, Selecting, and Configuring
i. Press
[>]
to move the cursor to the
Server Address
field.
ii. Enter the IP address of the SNTP server you want the switch to
use for time synchronization.
Note: This step replaces any previously configured server IP
address. If you will be using backup SNTP servers (requires use
of the CLI), then refer to “SNTP Unicast Time Polling with
Multiple SNTP Servers” on page 9-24.
iii. Press
[v]
to move the cursor to the
Server Version
field. Enter the
value that matches the SNTP server version running on the device
you specified in the preceding step (step ii). If you are unsure
which version to use, ProCurve recommends leaving this value
at the default setting of
3 and testing SNTP operation to determine
whether any change is necessary.
Note: Using the menu to enter the IP address for an SNTP server
when the switch already has one or more SNTP servers config­
ured causes the switch to delete the primary SNTP server from
the server list and to select a new primary SNTP server from the
IP address(es) in the updated list. For more on this topic, refer to
“SNTP Unicast Time Polling with Multiple SNTP Servers” on page
9-24.
iv. Press
[>]
to move the cursor to the Poll Interval field, then go to
step 6.
Note: The Menu interface lists only the highest priority SNTP server, even if others are configured. To view all SNTP servers configured
on the switch, use the CLI show management command. Refer to “SNTP Unicast Time Polling with Multiple SNTP Servers” on page
9-24.
