connect with port Ethernet1/12 of Switch1 and port Ethernet1/13 of Switch2, and enable the
source address check function of SAVI. Ethernet1/1 and Ethernet1/2 are uplink ports of
Switch1 and Switch2 respectively, enable DHCP trust and ND trust functions. Aggregation
Switch3 enables DHCPv6 server function and route advertisement function.
Configuration steps of SAVI DHCP-SLAAC scene:
Switch1>enable
Switch1#config
Switch1(config)#savi enable
Switch1(config)#savi ipv6 dhcp-slaac enable
Switch1(config)#savi check binding probe mode
Switch1(config)#interface ethernet1/1
Switch1(config-if-ethernet1/1)#ipv6 dhcp snooping trust
Switch1(config-if-ethernet1/1)#ipv6 nd snooping trust
Switch1(config-if-ethernet1/1)#exit
Switch1(config)#interface ethernet1/12-20
Switch1(config-if-port-range)#savi ipv6 check source ip-address mac-
address
Switch1(config-if-port-range)#savi ipv6 binding num 4
Switch1(config-if-port-range)#exit
Switch1(config)#exit
Switch1#write
52.4 SAVI Troubleshooting
After ensure no problem about SAVI client hardware and cable, please check the status which
may exist and the propositional solutions in the following:

If IPv6 packets are filtered incorrectly after enable SAVI function, please ensure the
global SAVI function enabled. After that, enable the global function of the
corresponding SAVI scene according to the actual application scene and enable the
port authentication function.

If client can not correctly obtain IPv6 address assigned by DHCPv6 server after enable
SAVI function, please ensure DHCP port trust is configured by uplink port with
DHCPv6 server.

If node binding can not be set for the new user after enable SAVI function, please
check whether the direct-link port configures the max binding number, and whether the
binding number reaches to the max number. If the binding number exceeds the max
binding limit, it is recommended to configure the bigger binding limit.
