This section describes how to check the configuration of
defense against man-in-the-middle attacks and IP/MAC address spoofing.
Prerequisites
The configuration of defense against man-in-the-middle attacks
and IP/MAC address spoofing is complete.
Procedure
- Run the display dhcp snooping global command to check the
global DHCP snooping information.
- Run the display dhcp snooping bind-table { all | dynamic | interface interface-type interface-number | ip-address ip-address | mac-address mac-address | static | vlan vlan-id [interface interface-type interface-number ] | vsi vsi-name | bridge-domain bd-id } command to check the information
about the Dynamic Host Configuration Protocol (DHCP) snooping binding
table.
- Run the display dhcp snooping { interface interface-type interface-number | vlan vlan-id [ interface interface-type interface-number ] | bridge-domain bd-id } command to check the DHCP snooping
configuration.
- Run the display dhcp option82 configuration [ interface interface-type interface-number | vlan vlan-id | bridge-domain bd-id ] command to check the Option 82 configuration.
