Configuring the DHCP Agent Circuit ID Suboption
  
  
    
        To configure the values used to create the agent circuit
          ID suboption, use the following commands:
        configure bootprelay dhcp-agent
          information circuit-id port-information port_info port
          port
        configure bootprelay dhcp-agent
          information circuit-id vlan-information vlan_info {vlan}
          [vlan_name |all]
        
          
Note   
When both ipsecurity DHCP option and bootprelay DHCP agent option are configured,
            the Bootprelay DHCP agent option takes higher precedence.
