config dhcp_relay option_82 state 

Purpose 

Used to configure the state of DHCP relay agent information option 82 of the 
switch. 

Syntax 

config dhcp_relay option_82 state [enable | disable] 

Description 

This command is used to configure the state of DHCP relay agent information 
option 82 of the switch. 

Parameters 

enable - When this field is toggled to Enabled the relay agent will insert and 
remove DHCP relay information (option 82 field) in messages between DHCP 
server and client. When the relay agent receives the DHCP request, it adds the 
option 82 information, and the IP address of the relay agent (if the relay agent is 
configured), to the packet. Once the option 82 information has been added to 
the packet it is sent on to the DHCP server. When the DHCP server receives 
the packet, if the server is capable of option 82, it can implement policies like 
restricting the number of IP addresses that can be assigned to a single remote 
ID or circuit ID. Then the DHCP server echoes the option 82 field in the DHCP 
reply. The DHCP server unicasts the reply to the back to the relay agent if the 
request was relayed to the server by the relay agent. The switch verifies that it 
originally inserted the option 82 data. Finally, the relay agent removes the 
option 82 field and forwards the packet to the switch port that connects to the 
DHCP client that sent the DHCP request. 

disable - If the field is toggled to disable the relay agent will not insert and 
remove DHCP relay information (option 82 field) in messages between DHCP 
servers and clients, and the check and policy settings will have no effect. 

Restrictions 

Only Administrator and Operator-level users can issue this command. 

Example usage: 

To configure DHCP relay option 82 state:

 

DES-3526:admin#config dhcp_relay option_82 
state enable 

Command: config dhcp_relay option_82 state 
enable 

 

Success. 

 

DES-3526:admin# 

 

config dhcp_relay option_82 check 

Purpose 

Used to configure the checking mechanism of DHCP relay agent 
information option 82 of the switch. 

Syntax 

config dhcp_relay option_82 check [enable | disable] 

Description 

This command is used to configure the checking mechanism of 
DHCP/BOOTP relay agent information option 82 of the switch.  

Parameters 

enable  –  When  the  field  is  toggled  to  enable,  the  relay  agent  will  check 
the validity of the packet’s option 82 field. If the switch receives a packet 
that contains the option 82 field from a DHCP client, the switch drops the 
packet because it is invalid. In packets received from DHCP servers, the 
relay agent will drop invalid messages. 

disable - When the field is toggled to disable, the relay agent will not 
check the validity of the packet’s option 82 field. 

Restrictions 

Only Administrator and Operator-level users can issue this command. 

Example usage: 

To configure DHCP relay option 82 check:
