Description

This command configures an L2TPLayer-2 Tunneling Protocol. L2TP is a networking protocol used by the ISPs to enable VPN operations. or IPsecInternet Protocol security. IPsec is a protocol suite for secure IP communications that authenticates and encrypts each IP packet in a communication session. VPNVirtual Private Network. VPN enables secure access to a corporate network when located remotely. It enables a computer to send and receive data across shared or public networks as if it were directly connected to the private network, while benefiting from the functionality, security, and management policies of the private network. This is done by establishing a virtual point-to-point connection through the use of dedicated connections, encryption, or a combination of the two. connection.

Syntax

Parameter

Description

Range

Default

client configuration

Configures parameters for the remote clients.

dns

Configures a primary and optional secondary DNSDomain Name System. A DNS server functions as a phone book for the intranet and Internet users. It converts human-readable computer host names into IP addresses and IP addresses into host names. It stores several records for a domain name such as an address 'A' record, name server (NS), and mail exchanger (MX) records. The Address 'A' record is the most important record that is stored in a DNS server, because it provides the required IP address for a network peripheral or element. server.

wins

Configures a primary and optional secondary WINS server.

disable|enable

Disables or enables termination of L2TPLayer-2 Tunneling Protocol. L2TP is a networking protocol used by the ISPs to enable VPN operations. clients.

enabled

l2tp tunnel hello

Configures L2TPLayer-2 Tunneling Protocol. L2TP is a networking protocol used by the ISPs to enable VPN operations. tunneling hello timeout, in seconds.

10-1440

60 seconds

no

Negates any configured parameter.

ppp authentication

Enables the protocols for PPPPoint-to-Point Protocol. PPP is a data link (layer 2) protocol used to establish a direct connection between two nodes. It can provide connection authentication, transmission encryption, and compression. authentication. This list should match the L2TPLayer-2 Tunneling Protocol. L2TP is a networking protocol used by the ISPs to enable VPN operations. configuration configured with the vpn-dialer command on the managed device.

CACHE-SECURID

The managed device caches Secure ID tokens so that the user does not need to reauthenticate each time a network connection is lost.

CHAP

Use CHAPChallenge Handshake Authentication Protocol. CHAP is an authentication scheme used by PPP servers to validate the identity of remote clients. with PPPPoint-to-Point Protocol. PPP is a data link (layer 2) protocol used to establish a direct connection between two nodes. It can provide connection authentication, transmission encryption, and compression. authentication.

EAP

Use EAP-TLSEAP–Transport Layer Security. EAP-TLS is a certificate-based authentication method supporting mutual authentication, integrity-protected ciphersuite negotiation and key exchange between two endpoints. See RFC 5216. with PPPPoint-to-Point Protocol. PPP is a data link (layer 2) protocol used to establish a direct connection between two nodes. It can provide connection authentication, transmission encryption, and compression. authentication. Specify this protocol for Windows IPsecInternet Protocol security. IPsec is a protocol suite for secure IP communications that authenticates and encrypts each IP packet in a communication session. VPNVirtual Private Network. VPN enables secure access to a corporate network when located remotely. It enables a computer to send and receive data across shared or public networks as if it were directly connected to the private network, while benefiting from the functionality, security, and management policies of the private network. This is done by establishing a virtual point-to-point connection through the use of dedicated connections, encryption, or a combination of the two. clients that use Common Access Card (CACCall Admission Control. CAC regulates traffic volume in voice communications. CAC can also be used to ensure or maintain a certain level of audio quality in voice communications networks.) Smart Cards that contain user information and digital certificatesA digital certificate is an electronic document that uses a digital signature to bind a public key with an identity—information such as the name of a person or an organization, address, and so forth..

MSCHAP

Use MSCHAP with PPPPoint-to-Point Protocol. PPP is a data link (layer 2) protocol used to establish a direct connection between two nodes. It can provide connection authentication, transmission encryption, and compression. authentication.

MSCHAPv2

Use MSCHAPv2 with PPPPoint-to-Point Protocol. PPP is a data link (layer 2) protocol used to establish a direct connection between two nodes. It can provide connection authentication, transmission encryption, and compression. authentication. This is the default for L2TPLayer-2 Tunneling Protocol. L2TP is a networking protocol used by the ISPs to enable VPN operations.

PAP

 

ppp securid

If CACHE-SECURID is configured for PPPPoint-to-Point Protocol. PPP is a data link (layer 2) protocol used to establish a direct connection between two nodes. It can provide connection authentication, transmission encryption, and compression. authentication, this specifies the time, in minutes, that the token is cached.

Usage Guidelines

L2TPLayer-2 Tunneling Protocol. L2TP is a networking protocol used by the ISPs to enable VPN operations. or IPsecInternet Protocol security. IPsec is a protocol suite for secure IP communications that authenticates and encrypts each IP packet in a communication session. relies on the PPPPoint-to-Point Protocol. PPP is a data link (layer 2) protocol used to establish a direct connection between two nodes. It can provide connection authentication, transmission encryption, and compression. connection process to perform user authentication and protocol configuration. You specify the protocol used for PPPPoint-to-Point Protocol. PPP is a data link (layer 2) protocol used to establish a direct connection between two nodes. It can provide connection authentication, transmission encryption, and compression. authentication and whether SecureID tokens are cached on the managed device. Client addresses are assigned from a pool configured with the ip local pool command.
