Explanation:
* dhcp-snooping information enable
Use the dhcp-snooping information enable command to enable DHCP snooping Option 82.
* dhcp-snooping information strategy replace
Use the dhcp-snooping information strategy command to configure the handling strategy for
Option 82 in requesting messages.
Parameters

drop: Drops the requesting message containing Option 82.
keep: Forwards the requesting message containing Option 82 without changing Option 82.
replace: Forwards the requesting message containing Option 82 after replacing the original Option
82 with the one padded in specified format.
* dhcp-snooping information remote-id string switch001
Use the dhcp-snooping information remote-id command to configure the remote ID sub-option
in Option 82.
* display dhcp-snooping
Use the display dhcp-snooping command to display the user IP-MAC address mapping entries
recorded by the DHCP snooping function.
Only the address 10.1.10.10 is being displayed
The address 10.1.10.2 is not displayed. This ARP packet will be dropped.
Note: DHCP snooping is an important component in the defense against ARP spoofing. ARP
security checks the IP address in the Source Protocol Address field of ARP packets. If that IP
address is not an address that DHCP snooping has recorded as being in use by a host connected
to the ingress port of the ARP, then the ARP packet is dropped.
