1.7.208 SNTP-HOST

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 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.
If no network problems exist, ensure that the ONS 15310-CL or ONS 15310-MA proxy is provisioned
Step 3
