Usage Information

By default, option 82 is enabled globally. When option 82 is enabled globally, the relay agent adds the client information to the packet and sends it to the server. When option 82 is disabled globally, the client packets are sent to the server without option 82 information. When both global as well as interface level option 82 configurations are present , the configuration to disable option 82 takes precedence. The following table shows the option 82 status depending on the global and interface level configurations:

Table 1. Option 82 status
Global Level	Interface Level	Option 82 status
Enable	Enable	Adds option 82 information to the packet.
Enable	Disable	Does not add option 82 information to the packet.
Disable	Enable	Does not add option 82 information to the packet.
Disable	Disable	Does not add option 82 information to the packet.
