Usage Guidelines

Usage Scenario

After the client-option38 command is run, the server trusts the information in the Option 38 field of DHCPv6 messages sent by the client and sends the information in the Option 38 field to the RADIUS server. Option38 functions the same as the subscriber-id of Option 82 in DHCPv4.

Precautions

In VS mode, this command is supported only by the admin VS.

Example

# On GE 0/1/9, configure the server to trust the information in the Option 38 field of the DHCPv6 messages sent by the client.
