the destination echoes a reply, and the command returns the amount of time it took to reach the
destination and back.
To troubleshoot an intermittent FCIP link, run the ping command for an extended period of time,
recording the output. The output should be evaluated looking for large deviations in the ping-time
or lost-packets. Also use the maximum packet-size for the ping test; using the 56-byte default
packet size is not a typical packet size for FCIP. Figure 126 (page 145) illustrates the ping command.

FCIP Route Link Failure – Event Log Entries
Table 29 (page 145) provides an example of four event log entries that are typical for a simple link
failure. The following two terms used in the event log entries are defined here for clarity:
• A jiffy is a time increment; in this error log entry, there are 100 jiffies in a second.
• A TCP fast retransmission is one where TCP retries the transmission but does not bring down
the connection between the end nodes. In simple terms, it is a lost or duplicate ACK.
