Identifying OS Release Version and Build Number

Identifying OS Release Version and Build Number
The operating system can be configured to provide services and perform pre-defined functions through
commands issued from the CLI or through the Web Element Manager application.
The operating system software is delivered as a single binary file (.bin file extension) and is loaded as a single
instance for the entire system.
• For StarOS releases prior to 16.1, tthe image filename is identified by its release type, build number
• For StarOS release 16.1 onwards, the image filename is identified by a suffix identifying its platform
For StarOS releases 20.0 and higher, a starfile image must be signed with an REL key before being released.
A deployable image will be signed with an REL key having a ".bin.SPA" extension, where "A" identifies the
revision level of the signing key. For example, asr5000-20.0.0.bin.SPA. If a signing key becomes compromised,
a new key is created and the revision level increments to "B".
For StarOS releases 20.0 and higher Trusted images have been introduced. The difference between a Trusted
build and a Normal build is the absence of unsecure programs ftpd, telnet and tcpdump, as well as the addition
of a staros.conf file for security options. Trusted images are identifiable by the presence of "_T" in the platform
name. For example, asr5000_T-20.0.0.bin.SPA).
The software version information can be viewed from the CLI in the Exec mode by entering the show version
command.
[local

release.
