Chapter 4 Testing and Configuring the TimeHub
Testing the NTP Cards
For simplicity, this procedure verifies Port A in a no-bond state. Port A on both cards
must be routed through a switch, connecting both ports to one computer for
verification. This procedure also uses the SymmTime™ application available at
www.symmetricom.com. Follow the on-line instructions to download and install the
application. You must have administrator rights on the computer in order to install
SymmTime.
For this example two NTP Server cards have been installed on a Master shelf in
slots 3B and 4B.
1. Verify the state of the bonding mode:
RTRV-EQPT::S0-OUTB:CTAG:::PARAMETER=BONDMODE;
If the response is N, skip to step 3.
2. Disable the bonding mode if it is active:
ED-EQPT:::S0-OUTB:CTAG:::BONDMODE=NOBOND;
ED-EQPT::S0-OUTB:CTAG:::NTPPAIR=APPLYCFG;
3. Set the NTP Server card in slot 3B as the Active card:
ED-EQPT:::S0-OUT3B:CTAG:::NTPSLOT=ACT;
4. Repeat steps 1 – 10 of the procedure in Verifying the NTP Server Function, on
page 191 to verify that the NTP Server card in slot 3B is functional.
If the NTP Server card or the connection to the NTP Server card is not working,
a message appears that says SymmTime cannot connect to the server.
Troubleshoot the connection first, then the NTP Server card.
5. Set the NTP Server card in the slot 4B as the active card:
ED-EQPT:::S0-OUT4B:CTAG:::NTPSLOT=ACT;
6. Click Sync Now in the SymmTime application. The new time and any offset
from the NTP Server card appears. This verifies that the NTP Server card in slot
4B is now working with the same IP address as the NTP Server card in slot 3B.
If the NTP Server card or the connection to the NTP Server card is not working,
a message appears that says SymmTime cannot connect to the server.
Troubleshoot the connection first, then the NTP Server card.
Click Sync Now a few more times and verify the response.The switch may
delay the response.
7. Remove the cable from the Port A SFP on the NTP Server card in slot 3B.
