2. Use the setntp(8) command to change a clock address of the XSCF's own local

clock.

When you use the setntp(8) command to specify the localaddr value, execute the

rebootxscf(8) command to apply the specified configuration and reset the XSCF.

3. Use the showntp(8) command to confirm the clock address of the XSCF's own local

clock.

Note – The setting of the XSCF's own local clock by setntp(8) command is supported

only on M3000/M4000/M5000/M8000/M9000 servers that run certain versions of XCP

firmware (beginning with XCP 1091).

■ Notes on the NTP Server Referring to the Local Clock

When the NTP server which XSCF refers to is referring to the server's own system time

(local clock), and when the address of "127.127.1.0" is set to that local clock, time

synchronization in XSCF might fail.

The address of the XSCF's own local clock is fixed to "127.127.1.0." On the other hand,

when the address of the local clock of the NTP server which XSCF refers to is set to

"127.127.1.0," the address of the clock source (refid) has the same value as the address of the

XSCF's own local clock. An NTP server like this is excluded from the target of XSCF time

synchronization.

You can execute the showntp -l command to refer to the address of the NTP server's own

clock source which is set in XSCF and the address of the XSCF's own local clock.

<Example> Set 1 as the least significant byte of the clock address.

XSCF> setntp -m localaddr=1

Please reset the XSCF by rebootxscf to apply the ntp settings.

XSCF> showntp -m

prefer : on

localaddr : 1

XSCF> showntp –l
