Field Name Definition
Destination Location for the data files. Either Local or Remote.
Mode (Local Destination)
Willbe either circular or linear. In circular mode, data is written into the specified
local data file until the upper limit on the file size is reached; then the data is
overwritten starting from the top of the file as additional data comes in. Circular
buffering requires the administrator to set up processes to examine the data
during the timeframe before the data is overwritten by new data. In linear mode,
the kernel serial driver buffer is used to store the Rx data. Once the 4Kb is
reached, a flow control stop is issued to prevent the serial port from receiving
further data from the remote peer.
File Size (Bytes) (Local
Destination)
The maximum file size for the data buffer file. The file size must be greater than
zero.
NFS File Path (Remote
Destination)
The path for the mount point of the directory where data buffer file is to be
stored.
NOTE: The NFS server must already be configured with the mount point
shared (exported) and the shared directory from the NFS server must be
mounted on the console server.
Record the timestamp. Save a timestamp with the data in the data buffer file.
Syslog Server The IP address for the preconfigured Syslog server.
Facility Number
Choose a facility number to assign to the console server. Obtain the facility
number for the console server from the system administrator of the syslog
server. The facility number is included in any syslog message generated from
the console server. The server’s administrator can use facility numbers to isolate
logs from individual devices into individual files.
Options range from Local0 to Local7.
Syslog Buffer Size Maximum size of the buffer in the Syslog server.
Buffer SysLog at all times As indicated.
Buffer SysLog only when no
user is connected to the port
As indicated.
Hostname Discovery
Check to enable the console server to attempt to discover the hostname of the
server connected to the serial port.
