Command Usage
The switch will use a DHCPv6 server specified configuration file when the
switch is assigned an IPv6 address from a DHCPv6 server. Either ipv6 address
autoconfig or ipv6 address dhcp command must be configured along with this
command for the switch to use the specified configuration file in DHCPv6
packet.
The correct packets that The DHCPv6 reply must contain Option 59 which
contains a URL to a configuration file and Option 60 which contains the
configuration file name. If the host in the URL is expressed using an IPv6
address rather than a domain name, the address in the URL must be enclosed in
"[" and "]" characters.
You must configure your DHCPv6 server to support DHCPv6 options 59 and 60.
If ip and ipv6 dhcp dynamic-provision is disabled the default start-up
configuration file is used. If the start-up file is the Edgecore provided
Factory_Default_Config.cfg file, the default status is disabled.
If the address of VLAN 1 is configured as DHCPv6 mode, the switch will check if
it has received any remote DHCPv6 information every 5 seconds. If no
information is received, the switch DHCPv6 client will keep sending a DHCPv6
request once per minute.
Dynamic provisioning will not be processed if the address mode of the switch is
user configured (i.e. no dynamic address assigned).
If the address mode has been restored from user configuration to be DHCPv6
mode, the dynamic configuration procedures will be processed again.
Once a configuration file has been downloaded using TFTPv6, the dynamic
provision process will stop.
The configuration file size stored on the remote server must be smaller than the
available memory of the switch.
To comply with TFTP the boot filename length on the server can be a maximum
of 127 characters whereas on the switch only 32 characters are supported.
