Commands for Security Function Chapter 6 Commands for TACACS+
This command configures the DHCP snooping to append the option82 information for DHCP
requests when dot1x dhcpoption82based authentication is applied. By default, for un-authenticated
users, the switch appends to the option 82 field of the DHCP requests with the remote-id field as
unauth, and the circuit-id field as the MAC address of the CPU port of the switch. The DHCP server
allocates addresses based on the information provided by the option82 field. And users can retrieve
different IP addresses before and after authentication. When this command is applied, DHCP relay
should not be configured on the truck switch which is connected to the local access switch.
Example:
Enable option82 function of DHCP Snooping.
switch(Config)#ip dhcp snooping option82 enable

server.
Example:
Enable encrypt or hash function of private message.
