Usage
Information
RFC 3986 specifies that IPv6 host addresses in a uniform resource identifier (URI) must be enclosed in
square brackets, [X:X:X:X::X]. For maximum flexibility this command accepts IPv6 host addresses with or
without the square brackets.
After you upgrade the system image, using the upgrade system command, specify the default boot
location using the boot system command. Save the configuration to the startup configuration file using
the write memory command and reload the system using the reload command to use the new Dell
EMC Networking OS software.
If you enable the verified boot feature using the verified boot command, the upgrade system
command prompts you to enter the hash value of the Dell EMC Networking OS image. This is applicable
only for the local partitions such as A: or B:. You can get the hash from the iSupport page.
NOTE: You can apply a set of configurations, available only in the new version to which you want to
upgrade the system to, without having to re-boot the system twice. In order to accomplish this
seamless upgrade, perform the following tasks:
