sysApplInstallPkgIndex
sys Appl Install Pkg Index
1.3.6.1.2.1.54.1.1.1.1.1
An integer used only for indexing purposes. Generally monotonically increasing from 1 as new applications are installed. The value for each installed application must remain constant at least from one re-initialization of the network management entity which implements this MIB module to the next re-initialization. The specific value is meaningful only within a given SNMP entity. A sysApplInstallPkgIndex value must not be re-used until the next agent entity restart in the event the installed application entry is deleted.
