Use the ipv6 address eui-64 command to configure a site-local address or global unicast address in the EUI-64 format for an interface.
Use the undo ipv6 address eui-64 command to remove the configured site-local address or global unicast address in the EUI-64 format for an interface.
By default, no site-local or global unicast address in EUI-64 format is configured for an interface.
Note that:
l The prefix length should not be more than 64 bits when the aggregatable global unicast address(es) or site-local address(es) in the EUI-64 format is configured in the VLAN interface view.
l The prefix length can only be 128 bits when the aggregatable global unicast address(es) or site-local address(es) in the EUI-64 format is configured in the LoopBack interface view.

2.1.6 tftp-server ipv6 acl
Syntax
tftp-server ipv6 acl acl-number
undo tftp-server ipv6 acl
View
System view
Parameter
acl-number: ACL number of IPv6, in the range of 2000 to 2999.
Description
Use the tftp-server ipv6 acl command to configure the relation of ACL to TFTP application. You can use the rules configured in IPv6 ACL to enable or disable a specific TFTP server.
Use the undo tftp-server ipv6 acl command to disable the relation of ACL to TFTP application.
ACL is not related to TFTP application by default.
Example
# Configure the relation of ACL2000 to TFTP application
<H3C> system-view
[Sysname] acl ipv6 number 2000
[Sysname-acl6-basic-2000] rule permit source 2030:5060::9050/64
[Sysname-acl6-basic-2000] quit
[H3C] tftp-server ipv6 acl 2000
2.1.7 tracert ipv6
Syntax
tracert ipv6 [ -f first-ttl | -m max-ttl | -p port | -q packet-number | -w timeout ]* remote-system
View
Any view
Parameter
-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 UDP port number of the destination device, in the range 1 to 65535. The default value is 33434. It is normally unnecessary to modify this parameter.
-q packet-number: Specifies the number of probe packets sent each time, in the range 1 to 65535 and defaults to 3.
-w timeout: Specifies the timeout time of the probing packets, ranging from 1 to 65535, in milliseconds. The default value is 5000 ms.
remote-system: IPv6 address or host name (a string a 1 to 20 characters) of the destination device.
Description
Use the tracert ipv6 command to trace the route of the IPv6 packets from source to destination.
Example
# Trace the route of the IPv6 packets from source to destination 3002::2.
<H3C> tracert ipv6 3002::1
traceroute to 3002::1 30 hops max,60 bytes packet
1 3003::1 30 ms 0 ms 0 ms
2 3002::1 10 ms 10 ms 0 ms
