Parameters
prefix-length: Prefix length of an IPv6 address, in the range of 1 to 128.
Description
Use the ipv6 address command to configure a site-local address or global unicast address manually for an interface.
Use the undo ipv6 address command to remove the manually configured interface address.
By default, no site-local address or global unicast address is configured for an interface.
Note that:
l An H3C S3600 Ethernet switch can have IPv6 unicast addresses configured on only one VLAN interface. The total number of IPv6 global unicast addresses and site-local addresses configured on an interface can be up to four.
l You will remove all IPv6 addresses except the automatically configured link-local address if you carry out the undo ipv6 address command without any parameter specified.

ipv6 address auto link-local
Syntax
ipv6 address auto link-local
undo ipv6 address auto link-local
View
VLAN interface view
Parameters
None
Description
Use the undo ipv6 address auto link-local command to remove the automatically generated link-local address for an interface.
By default, a link-local address is generated automatically after a site-local IPv6 address or global unicast address is configured for an interface.
Note that:
l After an IPv6 site-local address or aggregatable global unicast address is configured for an interface, a link-local address is generated automatically. The automatically generated link-local address is the same as the one generated by using the ipv6 address auto link-local command.
l The undo ipv6 address auto link-local command can be used only after the ipv6 address auto link-local command is executed. However, if an IPv6 site-local address or aggregatable global unicast address is already configured for an interface, the interface still has a link-local address because the system automatically generates one for the interface. If no IPv6 site-local address or aggregatable global unicast address is configured, the interface has no link-local address.
l Manual assignment takes precedence over automatic generation. That is, if you first adopt automatic generation and then manual assignment, the manually assigned link-local address will overwrite the automatically generated one. If you first adopt manual assignment and then automatic generation, the automatically generated link-local address will not take effect and the link-local address of an interface is still the manually assigned one. If you delete the manually assigned address, the automatically generated link-local address is validated. For manually assignment of an IPv6 link-local address, refer to the ipv6 address link-local command.

Note that:
You can configure a static neighbor entry in two ways:
l Mapping a VLAN interface to an IPv6 address and a link-layer address. The entry state is INCMP. After the switch get the layer 2 port information of the VLAN, the neighbor entry enters the REACH state.
l Mapping a Layer 2 port in a VLAN to an IPv6 address and a link-layer address. The Layer 2 port specified by the port-type port-number argument must belong to the VLAN specified by the vlan-id argument, and the corresponding VLAN interface must exist. After you carry out the command, the device relates the VLAN interface to the IPv6 address to uniquely identify a static neighbor entry which is in REACH state.
You only need to specify the corresponding VLAN interface when removing a static neighbor entry related to that VLAN interface.

Parameters
remote-system: IPv6 address or host name (a string a 1 to 46 characters) of the destination device.
-i interface-type interface-number: Specifies the type and number of an interface. This argument takes effect only when the address of the TFTP server is a link-local address and the specified outgoing interface has a link-local address.
get: Specifies to download a file.
put: Specifies to upload a file.
source-filename: Specifies the name of a source file with a string of 1 to 64 letters.
destination-filename: Specifies the name of a destination file with a string of 1 to 64 letters. If no such parameters are specified, then the destination file’s name will be the same as the source file’s.
Description
Use the tftp ipv6 command to perform the following operations:
l Download a file: Download a specified source file from TFTP server to local.
l Upload a file: Upload a specified source file from local to TFTP server.
Examples
# Download a file from TFTP server.
<Sysname> tftp ipv6 fe80::250:daff:fe91:e058 -i Vlan-interface 300 get filetoget

tracert ipv6
Syntax
tracert ipv6 [ -f first-ttl | -m max-ttl | -p port | -q packet-num | -w timeout ]* remote-system
View
Any view
Parameters
-f first-ttl: Specifies the first TTL, that is, the allowed number of hops for the first packet. Ranges from 1 to 255, defaults to 1, and must be less than the maximum TTL.
-m max-ttl: Specifies the maximum TTL, that is, the maximum allowed number of hops for a packet. The value ranges from 1 to 255, defaults to 30. It must be greater than the first TTL.
-p port: Specifies the port number of the destination UDP, ranging from 1 to 65535, with the default of 33434.
-q packet-num: Specifies the maximum number of packets sent to a hop, ranging from 1 to 65535, with the default of 3.
-w timeout: Specifies the timeout in milliseconds of waiting ICMPv6 echoes, ranging from 1 to 65,535, with the default of 5,000 milliseconds.
remote-system: IPv6 address or host name (a string a 1 to 46 characters) of the destination device.
Description
Use the tracert ipv6 command to trace the route of the IPv6 packets from source to destination.
After using the ping command to detect a network problem, you can use the tracert command to locate the failed network node.
Executing the tracert command displays the IP addresses of all the Layer 3 forwarding devices which forward the packets to the destination on the path; if a device times out, “* * *” is displayed.
You can press Ctrl + C to terminate the tracert operation after the tracert ipv6 command is executed.
Examples
# Trace the route of the IPv6 packets from source to destination 3002::1.
<Sysname> tracert ipv6 3002::1
traceroute to 3002::1 30 hops max,60 bytes packet
1 3003::1 30 ms 0 ms 0 ms
