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:
1. Upgrade the system image to the new image and configure the primary partition to boot from the
new image using the boot system command.
2. Update the startup configuration file with the new set of configurations and then reload the
device using the reload command.
The new set of configurations are parsed from the startup configuration file and applied to the
NVRAM. During the system boot up, the new set of configurations are applied to the system from the
updated NVRAM configurations.
The following commands require NVRAM write to take effect in a single reload:
● Forwarding CLIs:
○ hardware forwarding-table mode {scaled-l2-switch | scaled-l3-routes
| scaled-l3-hosts}
○ cam-ipv6 extended-prefix {1024 | 2048 | 3072}
○ ip ecmp-group maximum-paths 2-64
● ACL CAM carving related CLIs:
○ cam-acl cli
○ cam-acl-vlan cli
○ cam-acl-egress cli
○ cam-sharing
● Feature keyword CLIs:
