The IPv6 address configuration commands are provided in the Interface VLAN Mode. Type enable
→configure→interface v lan {vlan-id} to enter the Interface Configuration Mode of the
management VLAN. By default the management VLAN is VLA N1. You can use the command ip
manage ment-v lan {vlan-id} in the Global Configuration Mode to configure the management VLAN.
ipv6 enable
Description
This command is used to enable the IPv6 function globally. The IPv6 function
should be enabled before the IPv6 address configuration management. By
default it is enabled. If the IPv6 function is disabled, the corresponding IPv6
netstack and IPv6-based modules will be invalid, for example SSHv6, SSLv6,
TFTPv6 etc. To disable the IPv6 function, please use no ipv6 enable command.
Syntax
ipv6 enable
no ipv6 enable
Command Mode
Interface Configuration Mode（interface vlan）
Example
Enable the IPv6 function when the management VLAN of the switch is VLAN1：
TL-SG3424(config)# interface vlan 1
TL-SG3424(config-if)# ipv6 enable
ipv6 address autoconfig
Description
This command is used to enable the automatic configuration of the ipv6 link-local
address. The switch has only one ipv6 link-local address, which can be
configured automatically or manually. The general ipv6 link-local address has the
prefix as fe80::/10. IPv6 routers cannot forward packets that have link-local
source or destination addresses to other links. The autuconfigured ipv6 link-local
address is in EUI-64 format. To verify the uniqueness of the link-local address,
the manually configured ipv6 link-local address will be deleted when the
autoconfigured ipv6 link-local address takes effect.
