The password to be used on the remote system when downloading the image. This value is maintained throughout (i.e. persisted) and can be used for additional/future download requests. This password is used for both zli 'update-image' commands and snmp/zms requests using this mib. The password is defaulted to NULL the first time the system is booted and is maintained across sw download requests and reboots. That is, the value is not cleared upon completion and can be reused by the manager.. When read, a NULL value is always returned.
