DHCP Client Profile Configuration Mode Commands

The Dynamic Host Configuration Protocol (DHCP) Client Profile Configuration Mode is used to create and manage DHCP client profile parameters. DHCP client profiles are associated with APNs.

Mode

Exec > Global Configuration > Context Configuration > DHCP Client Profile Configuration

configure > context context_name > dhcp-client-profile profile_name

Entering the above command sequence results in the following prompt: 

[context_name]host_name(config-dhcp-client-profile)#

Important

The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).

By default, this is disabled. With rapid commit, there can only be one server to which this can be sent.

rapid-commit-dhcpv4

Enables support of the rapid commit feature for DHCPv4 client functionality.

By default, this is enabled.

rapid-commit-dhcpv6

Enables support of the rapid commit feature for DHCPv6 client functionality.

By default, this is enabled.

user-class-option { imsi | msisdn }

Enables P-GW/GGSN to send USER_CLASS_OPTION in DHCPv6 messages to external DHCPv6 server during Prefix Delegation Setup.

imsi : Triggers sending the "User_Class_Option" with UE's IMSI in the DHCPv6 Request message from P-GW to the external DHCPv6 server during DHCPv6 Prefix Setup (for network behind UE).

msisdn : Triggers sending the "User_Class_Option" with UE's MSISDN in the DHCPv6 Request message from P-GW to the external DHCPv6 server during DHCPv6 Prefix Setup (for network behind UE).

By default, this is enabled.

Usage Guidelines

Use this command to enable options on the DHCP client.

Example

The following command enables support of the rapid commit feature for DHCPv6 client functionality:
