The EDD LCL command has the same effect as the former Option 11C EDD
command. Its sequence of operations is as follows:

1. Prior to an actual dump, the Main Cabinet or Chassis performs a security

check. If the security check fails, the datadump operation is aborted.

2. If the security check passes, the existing database files on the primary

flash drive are renamed with the extension ".bak".

3. The data is then written to the primary flash drive.

4. When the database files in the primary flash drive are updated, data and

patches are written to the internal backup flash drive (Z:).

Note: LD 43 and 143 are not available on an IP Expansion Cabinet or
Chassis in survival mode.

SWP, RES, and RIB commands for Survivability

To ensure the database synchronization on the main and the survivable IP
expansion cabinet(s) or chassis, the Swap (SWP), Restore (RES), and
Restore Backup (RIB) commands are modified to produce the same results
on the survivable IP expansion cabinet(s) or chassis as on the Main Cabinet
or Chassis.

The optional parameter, [], allows the technician to select a specific
cabinet or chassis in order to restrict the effect of the command to a specific
cabinet or chassis.

If no parameter is provided, the command is first performed on the Main
Cabinet or Chassis. The technician is then prompted with a confirmation
request. If , the command is performed on all survivable IP
Expansion Cabinets or Chassis.

As with the database download operation, preliminary security checks are
performed by the Main Cabinet or Chassis against the security ID and
software release of the survivable IP expansion cabinet(s) or chassis. If
these security checks fail for any cabinet or chassis, synchronization is
aborted for that cabinet or chassis.

SWP command

The SWP command is used to swap the regular and

"*.bak" copies of the database on the primary flash drive. It restores the
database to the state prior to the most recent datadump.

Figure 133 "SWP

command operation" (page 306)

illustrates the operation of the SWP

command. Only one IP expansion cabinet is shown for illustration purposes.
