Ping MPLS Results and Output

Table 111 summarizes the output in the ping MPLS display. If the Services Router receives no responses from the destination host, review the list after Table 111 for a possible explanation.

Table 111: 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 Services Router 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 Services Router 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.
