configure bootprelay dhcp-agent information circuit-id port-information

configure bootprelay dhcp-agent information circuit-id port-information port_info port port

Description

Configures the circuit ID sub-option that identifies the port for an incoming DHCP request.

Syntax Description

port_info Specifies a text string that becomes the circuit ID sub-option for the specified port. Specify a text string composed of 1 to 32 characters.
port Specifies the port to which the circuit ID sub-option is assigned.

Default

The default port_info is encoded as ((slot_number * 1000) + port_number/portIfindex). For example, if the DHCP request is received on port 3:12, the default circuit ID port_info value is 3012. On standalone switches, the slot number is one, so the default circuit ID port_info value is (1000 + port_number/portIfindex). For example, the default port_info for port 3 on a standalone switch is 1003.

Usage Guidelines

The full circuit ID string uses the format vlan_info-port_info . To configure the vlan_info portion of the circuit ID string, use the following command:

configure bootprelay dhcp-agent information circuit-id vlan-information vlan_info {vlan} [vlan_name|all]

To display the port_info information, use the following command:

show bootprelay dhcp-agent information circuit-id port-information ports all

Example

The following command configures the circuit ID port_info value slot1port3 for port 1:3:

configure bootprelay dhcp-agent information circuit-id port-information slot1port3 port 1:3
