IP Ping Test
An IP Ping test can be run to test connectivity between the DSU/CSU and any
NMS to which it has a route.
Times when you might want to run an IP Ping test are:
„
To verify the entire path between a newly installed remote site DSU/CSU and
the central site NMS. During a remote site installation, an IP Ping test is
typically run from the remote site to ping the NMS at the central site. The
remote DSU/CSU must have SNMP trap managers configured, and one of
those trap managers must be the central site NMS.
„
To test the path to the NMS trap managers during installation of the central site
DSU/CSU. The remote DSU/CSU must have configured the SNMP trap
managers to be sent the ping.
Procedure
To ping the NMS at the central site:
1. Verify that the central site NMS has the DSU/CSU’s IP address in its routing
table so it can communicate with the DSU/CSU.
2. Verify that the central site NMS’s router has the DSU/CSU’s IP address in its
routing table so it can communicate with the DSU/CSU.
3. Verify that the central site NMS has been configured as an SNMP Trap
Manager if the router is to route data, so a route has been configured within
the DSU/CSU.

6. Verify the results of the IP Ping test.
— While the test is running,
In Progress...
appears in the Status field.
— When the test is finished,
Alive. Latency =
nn
ms
should appear as
the Status (
nn
being the amount of time the test took in milliseconds).
If any other message is displayed, additional testing will be required.
