Chapter 2 Alarm Troubleshooting

2.7.208 SNTP-HOST

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

SONET Logical Object: NE

The Simple Network Timing Protocol (SNTP) Host Failure alarm indicates that an ONS 15310-CL or ONS 15310-MA serving as an IP proxy for the other nodes in the ring is not forwarding SNTP information to the other nodes in the network. The forwarding failure can result from two causes: either the IP network attached to the ONS proxy node is experiencing problems, or the ONS proxy node itself is not functioning properly.

Clear the SNTP-HOST Alarm

Step 1 Ping the SNTP host from a workstation in the same subnet to ensure that communication is possible within the subnet by completing the procedure in the “1.8.8 Verify Windows PC Connection to the Node (Ping)” section on page 1-50.

Step 2 If the ping fails, contact the network administrator who manages the IP network that supplies the SNTP information to the proxy and determine whether the network is experiencing problems which could affect the SNTP server/router connecting to the proxy ONS system.

Step 3 If no network problems exist, ensure that the ONS 15310-CL or ONS 15310-MA proxy is provisioned correctly by completing the following steps:

a.In node view for the node serving as the proxy, click the Provisioning > General tabs.

b.Ensure that the Use NTP/SNTP Server check box is checked.

c.If the Use NTP/SNTP Server check box is not checked, click it.

d.Ensure that the Use NTP/SNTP Server field contains a valid IP address for the server.

Step 4 If proxy is correctly provisioned, refer to the “Cisco Transport Controller Operation” chapter in the Cisco ONS 15310-CL and Cisco ONS 15310-MA Reference Manual for more information on SNTP Host for general information about working with SNTP. Refer to the “Turn Up Node” chapter in the Cisco ONS 15310-CL and Cisco ONS 15310-MA Procedure Guide.

Step 5 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1-800-553-2447).
