Chapter 2 Setting Up XSCF 2-99

Of the two NTP server outputs, the upper (192.168.1.2) indicates the NTP server which is set

by using the setntp(8) command. The refid is LOCAL(0), which means that the local

clock which has the address of "127.127.1.0" is set to the clock source of this NTP server. On

the other hand, the lower indicates the XSCF's own local clock. The address of the XSCF's

own local clock is fixed to "127.127.1.0."

Due to this, the NTP server (192.168.1.2) is excluded from the target of XSCF time

synchronization; which results in the XSCF synchronizes with its own local clock.

With any of the following measures to avoid the trouble, time can be correctly synchronized

with the NTP server which is set by using the setntp(8) command.

a. Change the clock source that the NTP server being set in XSCF refers to

Use the showntp -l command and check the clock source of the NTP server which is

set in XSCF. An NTP server which indicates the refid of LOCAL(0) in the output is

referring to the local clock which has the address of "127.127.1.0," and you should change

it to refer to another clock source.

When you change the clock source of an NTP server, make sure in advance that it has no

impact on other NTP clients.

b. Change the address of the local clock of the NTP server

Of the NTP server which XSCF refers to, change the address of the local clock to

"127.127.1.1," "127.127.1.2," or "127.127.1.3." Change /etc/inet/ntp.conf of

Oracle Solaris OS. To enable the change, restart of the NTP daemon is required.

When you change the address of the local clock of an NTP server, make sure in advance

that it has no impact on other NTP clients.

c. Change the stratum value of the NTP server

Of the NTP server which XSCF refers to, change the stratum value to "1." An NTP server

which has the stratum value of "1" becomes the most significant clock source and has no

refid. Therefore, there is no chance that it will have the same address as the XSCF's own

local clock.

When you change the stratum value of an NTP server, make sure in advance that it has no

impact on other NTP clients.

d. Change the address of the XSCF's own local clock

By using the setntp -m localaddr=value command, change the address of the

XSCF's own local clock. In value, specify the least significant byte of the clock address

of the local clock 127.127.1.x for value. A numeric from 0 to 3 can be specified. By
