Log File Transfer - Avaya 8800 Troubleshooting Manual

Log and trap fundamentals
two characters specify the slot number of the SF/CPU that generated the logs. The last
three characters (sss) denote the sequence number of the log file.
• The sequence number of the log file is incremented after every successful auto-transfer
of the file to the remote host.
• After reboot, the log file name with the highest sequence number on the PCMCIA (or
external flash) is used to store system messages. If the log file does not exist, a new log
file with the sequence number 000 is created.

Log file transfer

The system logs contain important information for debugging and maintaining your Avaya
Ethernet Routing Switch 8800/8600. When logging to the PCMCIA card (or external flash on
the 8895 SF/CPU), the log file is automatically transferred to a remote host when it reaches
your specified size parameters. You can configure up to 10 remote hosts, creating long-term
backup storage of your system log files.
Of the 10 configured remote hosts, 1 is the primary host and the other 9 are redundant. Upon
initiating a transfer, SMP always attempts to use host 1 first. If host 1 is not reachable, SMP
tries host 2, and then host 3, and on through the list of redundant hosts in sequential order
until it finds a reachable host.
If the autotransfer of the log file is unsuccessful, SMP logs any future messages in the DRAM
instead of the PCMCIA (or external flash).
You can specify the following information to configure the transfer criteria:
• Configurable log size parameters for the PCMCIA (or external flash) include:
- minsize—the minimum acceptable free space available on the PCMCIA (or external
flash) for logging
- maxsize—the maximum size of the log file on the PCMCIA (or external flash)
- maxoccupyPercentage—the amount of memory to use for SMP logging when the
maxsize parameter cannot be met
• The IP address of the remote host.
• The name of the log file that is to be stored on the remote host.
• The user name and password, if required. You can use the following command to
configure the user name and password:
config bootconfig host user <value> password <value>
Be aware of the following restrictions when transferring log files to a remote host:
• The remote host IP address must be reachable.
• When you transfer a log file from a host to the switch, (for example, to display it with the
show log file command), rename the log file. Failure to do so may cause the switch to use
the recently transferred file as the current log, if the sequence number in the extension is
higher than the current log file. For example, if bf860005.002 is the current log file and
you transfer bf860005.007 to the switch, the switch logs future messages to the
