FTP File Transfers
The FrameSaver unit supports a standard File Transfer Protocol (FTP) server
over Transmission Control Protocol (TCP). A complete binary image of the
configuration files can be copied to a host to provide a backup. To use this
feature, the unit must be configured to support Telnet and FTP Sessions.
Using this feature, you can transfer configuration files

to/from

a FrameSaver
node, program files

to

a FrameSaver node, and User History data

from

a
FrameSaver node through a user data port or the network interface using a
management PVC, or through the COM port.
Be aware of the following rules when doing a file transfer:
HYou must have Access Level 1 permission to use the put and get
commands. However, you can retrieve the data file for the user history
reports regardless of access level.
HYou cannot put a configuration file to the factory.cfg or current.cfg files
under the system directory. Configuration files should be put to a customer
file (cust1.cfg or cust2.cfg), then loaded into the downloaded unit’s Current
Configuration via the menu-driven user interface.
HYou can only put a NAM program file (nam.ocd) into a FrameSaver unit. You
cannot get a program file from the FrameSaver unit to a host.
HBefore putting a download file, you must use the bin binary command to
place the data connection in binary transfer mode.
HWhen transferring SLV user history information to the NMS, you can only get
a uhbcfull.dat file. It is recommended that you use the NMS application to get
this information (see

Transferring Collected Data

).
HA data file (uhbcfull.dat or lmitrace.syc) cannot be put into a FrameSaver
node.
HLMI packet capture data (lmitrace.syc) is not readable when the LMI Packet
Capture Utility is active.
HThe SLV user history file is only available to units with the SLV feature set.
FrameSaver units provide an additional feature that allows new software to be
downloaded in the background, using the selected bandwidth and without
interfering with normal operation. Downloads can be performed quickly, using the
full line speed, or at a slower rate over an extended period of time.
You initiate an FTP session to a FrameSaver node in the same way as you would
initiate an FTP to any other IP-addressable device.
NOTE:
Loading a configuration with many DLCIs from a unit’s Customer
Configuration 1 or 2 option area into its Current Configuration area may take
time. Allow a minute or more for the downloaded file to be put into the unit’s
currently active configuration.
