Downloading an IP preserve configuration file to an IPv6-based switch
To copy the file as the new startup-config file
on a switch, enter the TFTP copy command, as described
in SNMP management for IPv6,
If the switch's current IPv6 address for VLAN 1 was statically configured and not dynamically assigned by a DHCP/Bootp server, the switch reboots and retains its current IPv6 address, subnet mask, and gateway address. All other configuration settings in the downloaded configuration file are applied.
- If the switch's current IPv6 address for VLAN 1 was assigned from a DHCP server and not statically configured, IP preserve is suspended. The IPv6 addressing specified in the downloaded configuration file is implemented when the switch copies the file and reboots.
If the downloaded file specifies DHCP/Bootp as the source for the IPv6 address of VLAN 1, the switch uses the IPv6 address assigned by the DHCP/Bootp server.
If the file specifies a dedicated IPv6 address and subnet mask for VLAN 1 and a gateway IPv6 address, the switch implements these settings in the startup-config file.
