Cisco ASR 5500 User Manual

•
For StarOS releases prior to 16.1, the image filename is identified by its release type, build number and
platform type. For example: production.build_number.asr5500.bin. For example,
production.54029.asr5500.bin.
•
For StarOS release 16.1 onwards, the image filename is identified by a suffix specifying its platform
type and release number. For example, asr5500-release_number. bin. For example, asr5500-16.1.0.bin.
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, asr5500-20.0.0.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, asr5500_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]host_name# show version
You can run the Exec mode show build command to display additional information about the StarOS build
release.
Verify Free Space on the /flash Device

entering the following Exec mode command:
