Verifying the Link State of All Interfaces

Purpose

By using the ping tool on each peer address in the network, verify that all interfaces on the device are operational.

Action

For each interface on the device:

1. In the J-Web interface, select Diagnose>Ping Host.
2. In the Remote Host box, type the address of the interface for which you want to verify the link state.
3. Click Start. Output appears on a separate page.

Sample Output

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

Meaning

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 JUNOS Software Administration Guide.
