Procedure 6-21.1: Determine VLNC4x/VLNC6x software versions stored in non-volatile memory
Overview
The VLNC4x/VLNC6x contains up to two software loads, referred to as Image1 and Image2. Use this procedure to determine which of the image slots contains a valid software load and the version of each software load.
The show bootvar CLI command displays information for the version and the activation status of the current active and backup images. The command also displays any description text associated with an image. This command also displays the switch activation status.
This procedure assumes that the VLNC4x/VLNC6x has been previously installed.
Refer to the Alcatel-Lucent 1850 Transport Service Switch (TSS-5) Command Line Interface Guide, for help on using CLI commands.
