Managing Network Clock Sources
The following example shows the addsntprmtsvr command:
M8850_LA.8.PXM.a > addsntprmtsvr 172.29.52.88 -version 4 -primary yes
M8850_LA.8.PXM.a >
Step 5 Enter the addsntprmtsvr <options> command again to configure the secondary server.
M8850_LA.8.PXM.a > addsntprmtsvr <server IP address> -version {version} -primary no
This time, replace <server IP address> with the primary server’s IP address.
Note You do not include the -primary option with the command because the default setting for this parameter
is no. However, if you do include the -primary option in the command, be sure to set it to no.
In the following example, the user sets up a secondary server on the IP address 172.29.52.89.
M8850_LA.8.PXM.a > addsntprmtsvr 172.29.52.89 -version 4 -primary no
Step 6 Enter the cnfsntp command to configure SNTP sever parameters.
M8850_LA.8.PXM.a > cnfsntp {[-polling insecond] [-waiting insecond] [-rb insecond] [-client on|off]
[-server on|off] [-stratum 0-15]}
Table 7-11 describes the cnfsntp command parameters.
Modifying SNTP Servers
Enter the cnfsntprmtsvr command to modify the existing SNTP server, as shown in the following
example:
M8850_LA.8.PXM.a > cnfsntprmtsvr <server IP address> -version <version> -primary yes
Table 7-11 cnfsntp Command Parameters
Parameter Description
-polling Polling timer on the SNTP client. When this timer expires, the client
requests TOD from the server. The time range is from 64 to 10245 seconds.
(default = 64 seconds)
-waiting Waiting timer that automatically sets when the TOD request is sent to the
server. If this timer expires three times, the client switches over to the first
available secondary server for TOD. (default = 5 seconds)
-rb When a client switches over to the secondary server for TOD requests, the
rollback timer takes affect and continues polling the primary server for
TOD each time the rollback timer expires. The rollback timer continues
polling the primary server until it comes back up.
(default = 1024)
-client Toggles the SNTP client on or off.
-server Toggles the Primary SNTP server on or off.
-stratum Stratum of the SNTP client. The default is 0.
