To verify an interface configuration, perform these tasks:
By using the ping tool on each peer address in the network, verify that all interfaces on the Services Router are operational.
For each interface on the Services Router:
PING 10.10.10.10 : 56 data bytes 64 bytes from 10.10.10.10: icmp_seq=0 ttl=255 time=0.382 ms 64 bytes from 10.10.10.10: icmp_seq=1 ttl=255 time=0.266 ms
If the interface is operational, it generates an ICMP response. If this response is received, the round-trip time in milliseconds is listed in the time field. For more information about the output, see the J-series Services Router Administration Guide.
For more information about using the J-Web interface to ping a host, see the J-series Services Router Administration Guide.
For information about the ping command, see the J-series Services Router Administration Guide or the JUNOS Protocols, Class of Service, and System Basics Command Reference.
Verifying Interface PropertiesVerify that the interface properties are correct.
From the CLI, enter the show interfaces detail command.

The output shows a summary of interface information. Verify the following information:
Examine the operational statistics for an ADSL interface. Statistics in the ATU-R (ADSL transceiver unit–remote) column are for the near end. Statistics in the ATU-C (ADSL transceiver unit–central office) column are for the far end.
