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 dot1x configuration.
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
