Usage guidelines
A higher log output rate consumes more CPU resources. Adjust the log output rate based the CPU
performance and usage.
Examples
# Enable ND logging for user online and offline events, and set the maximum log output rate to 100
logs per second.
<Sysname> system-view
[Sysname] ipv6 nd online-offline-log enable rate 100
Related commands

ipv6 nd ra boot-file-url
Use
ipv6 nd ra boot-file-url
to specify the URL of the boot file in RA messages.
Use
undo ipv6 nd ra boot-file-url
to restore the default.
Syntax
ipv6 nd ra boot-file-url url-string
undo ipv6 nd ra boot-file-url
Default
RA messages do not carry the URL of the boot file.
Views
Interface view
Predefined user roles
network-admin
Parameters
url-string
: Specifies the URL address of the boot file, a case-sensitive string of 1 to 127
characters. The URL address must be started with http://, https://. ftp://, or tftp://.
Usage guidelines
In some specific networks, a device follows the steps to implement automatic configuration:
1.
Obtains an IPv6 address through ND or DHCPv6.
2.
Obtains the URL address for downloading the boot file from the DHCPv6 server.
3.
Downloads the boot file from the FTP server and installs it.
With the boot file URL specified in RA messages, the device can use the ND protocol to obtain both
the IPv6 address and the boot file URL for automatic configuration. DHCPv6 is not required in the
network, simplifying the network deployment.
Examples
# Specify the boot file URL address as tftp://169.254.0.1/file/softimg.iso in RA messages on
VLAN-interface 100.
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] ipv6 nd ra boot-file-url tftp://169.254.0.1/file/softimg.iso
