Usage Guide: DHCP SNOOPING will send the monitored binding information to HELPER
SERVER to save it. If the switch starts abnormally, it can recover the binding data from
HELPER SERVER. The HELPER SERVER function usually is integrated into DCBI
packet. The DHCP SNOOPING and HELPER SERVER use the UDP protocol to
communicate, and guarantee the arrival of retransmitted data. HELPER SERVER
configuration can also be used to sent DOT1X user data from the server, the detail of
usage is described in the chapter of ādot1x configurationā.
Two HELPER SERVER addresses are allowed, DHCP SNOOPING will try to connect to
PRIMARY SERVER in the first place. Only when the PRIMARY SERVER is unreachable,
will the switch c HELPER SERVER connects to SECONDARY SERVER.
Please pay attention: source address is the effective management IP address of the
switch, if the management IP address of the switch changes, this configuration should be
updated in time.
Example: Set the local management IP address as 100.1.1.1, primary HELPER SERVER
address as 100.1.1.100 and the port as default value.
switch(config)#interface vlan 1
switch(Config- If-Vlan1)#ip address 100.1.1.1 255.255.255.0
switch(Config-if-Vlan1)exit
switch(config)#ip user helper-address 100.1.1.100 source 100.1.1.1
