J-Web Ping MPLS Results and Output Summary
Table 1 summarizes the output in the ping MPLS display.
Table 1: J-Web Ping MPLS Results and Output Summary
Field | Description |
|---|---|
Exclamation point (!) | Echo reply was received. |
Period (.) | Echo reply was not received within the timeout period. |
x | Echo reply was received with an error code. Errored packets are not counted in the received packets count and are accounted for separately. |
number packets transmitted | number—Number of ping requests (probes) sent to a host. |
number packets received | number—Number of ping responses received from a host. |
percentage packet loss | percentage—Number of ping responses divided by the number of ping requests, specified as a percentage. |
time | For Layer 2 circuits only, the number of milliseconds required for the ping packet to reach the destination. This value is approximate, because the packet has to reach the Routing Engine. |
If the device does not receive ping responses from the destination host (the output shows a packet loss of 100 percent), one of the following explanations might apply:
- The host is not operational.
- There are network connectivity problems between the device and the host.
- The host might be configured to ignore echo requests.
- The host might be configured with a firewall filter that blocks echo requests or echo responses.
- The size of the echo request packet exceeds the MTU of a host along the path.
- The outbound node at the remote endpoint is not configured to handle MPLS packets.
- The remote endpoint's loopback address is not configured to 127.0.0.1.
