PTM

PTM

Context

The device supports the ADSL, VDSL, and G.SHDSL interface cards (together called DSL interface cards). DSL links can be used to connect the device to the Internet.

The VDSL and G.SHDSL interfaces can work in Asynchronous Transfer Mode (ATM) or Packet Transfer Mode (PTM) mode and switch between these two modes. An ADSL interface works only in ATM mode.

Ethernet packets are transmitted over DSL interfaces working in PTM mode. Service traffic can be transmitted over DSL links only when the interfaces work in the same mode as the peer device.

Procedure

  • Creating an Ethernet sub-interface
    1. Choose WAN Access > DSL Interface to display the DSL Interface page. Figure 12-17 shows DSL Interface page.
    2. Click PTM to display the PTM page.

      Figure 12-17  PTM

    3. Click Create in Ethernet Interface List to display the page for creating an Ethernet interface.
    4. Set the parameters described in Table 12-24.
    5. Click OK to complete the configuration.

      NOTE:

      The parameters for creating an Ethernet interface are the same as those in Ethernet Interface. After select an Ethernet interface from the Interface name drop-down list box, you can set the parameters according to the page (shown in the following figures) in Ethernet Interface.

      • Figure 12-18  Create Ethernet interface (Connection mode is IPv4 DHCP)

      • Figure 12-19  Create Ethernet interface (Connection mode is IPv4 Static)

      • Figure 12-20  Create Ethernet interface (Connection mode is IPv4 PPPoE)

      • Figure 12-21  Create Ethernet interface (Connection mode is IPv6 ND)

      • Figure 12-22  Create Ethernet interface (Connection mode is IPv6 DHCP)

      • Figure 12-23  Create Ethernet interface (Connection mode is IPv6 Static)

      • Figure 12-24  Create Ethernet interface (Connection mode is IPv6 PPPoE)

      Table 12-24  Description of the Ethernet interface parameters
      Parameter Description
      Interface name Type and number of an interface.
      • This parameter cannot be modified when the Ethernet interface configuration is modified.

      • When you set the parameters for creating an Ethernet sub-interface, select the Ethernet interface for which the sub-interface needs to be created.

      Description Description of an interface.

      By default, the description of an interface is empty.

      VLAN ID The VLAN ID must be entered when a user VLAN is terminated through a sub-interface.

      You can set this parameter only when creating an Ethernet sub-interface.

      IPv4

      IPv4 configuration parameters. The Connection mode parameter specifies the mode in which an interface obtains an IPv4 address.

      The options for Connection mode are as follows:

      • DHCP: indicates that the interface IPv4 address is automatically obtained using DHCP. For the description of DHCP parameters, see Table 12-25.
      • Static: indicates that the interface IPv4 address is manually configured. For the description of Static parameters, see Table 12-26.
      • PPPoE: indicates that the interface IPv4 address is obtained through PPP negotiation. For the description of PPPoE parameters, see Table 12-27.
      NOTE:

      You must select either IPv4 or IPv6 configuration.

      IPv6

      IPv6 configuration parameters. The Connection mode parameter specifies the mode in which an interface obtains an IPv6 address.

      The options for Connection mode are as follows:

      • ND: indicates that the interface IPv6 address is automatically configured. For the description of ND parameters, see Table 12-28.
      • DHCP: indicates that the interface IPv4 address is automatically obtained using DHCP. For the description of DHCP parameters, see Table 12-29.
      • Static: indicates that the interface IPv4 address is manually configured. For the description of Static parameters, see Table 12-30.
      • PPPoE: indicates that the interface IPv4 address is obtained through PPP negotiation. For the description of PPPoE parameters, see Table 12-31.
      NOTE:

      You must select either IPv4 or IPv6 configuration.

      Table 12-25  Description of the DHCP parameters (IPv4)
      Parameter Description
      NAT status NAT must be enabled when a PC on the private network of a LAN connects to the Internet.
      MTU (bytes) MTU of an interface.

      If the MTU is set too small and the size of packets is large, packets will be broken into a great number of fragments and be discarded by QoS queues. If the MTU is too large, packets are transmitted slowly or even lost.

      The default value of MTU is 1500.

      TCP-MSS (bytes) MSS of TCP packets on an interface.

      The MSS refers to the maximum length of a TCP packet segment sent from the peer device to the local device. During TCP connection negotiation, devices at both ends record the MSS of each other. When sending TCP packets, the devices limit the size of TCP packets within the MSS.

      The default value of TCP-MSS is 1200.

      VPN instance VPN instance bound to an interface.
      NOTE:

      Before setting this parameter, you must create an IPV4 VPN instance. For the detailed procedure, see VPN Instance.

      Table 12-26  Description of the Static parameters (IPv4)
      Parameter Description
      IP address IP address of an interface.

      The interface IP address cannot conflict with the IP addresses of other interfaces on the device or other devices in the network.

      Subnet mask Subnet mask of an interface.
      Default gateway Default gateway address of an interface.

      The default gateway address must be in the same network segment as the interface IP address.

      Secondary DNS server Secondary DNS server address assigned to a DHCP client.
      NAT status NAT must be enabled when a PC on the private network of a LAN connects to the Internet.
      MTU (bytes) MTU of an interface.

      If the MTU is set too small and the size of packets is large, packets will be broken into a great number of fragments and be discarded by QoS queues. If the MTU is too large, packets are transmitted slowly or even lost.

      The default value of MTU is 1500.

      TCP-MSS (bytes) MSS of TCP packets on an interface.

      The MSS refers to the maximum length of a TCP packet segment sent from the peer device to the local device. During TCP connection negotiation, devices at both ends record the MSS of each other. When sending TCP packets, the devices limit the size of TCP packets within the MSS.

      The default value of TCP-MSS is 1200.

      VPN instance VPN instance bound to an interface.

      Before setting this parameter, you must create an IPV4 VPN instance. For the detailed procedure, see VPN Instance.

      Table 12-27  Description of the PPPoE parameters (IPv4)
      Parameter Description
      NAT status NAT must be enabled when a PC on the private network of a LAN connects to the Internet.
      MTU (bytes) MTU of an interface.

      If the MTU is set too small and the size of packets is large, packets will be broken into a great number of fragments and be discarded by QoS queues. If the MTU is too large, packets are transmitted slowly or even lost.

      User name User name for PPPoE dial-up.
      Password Password for PPPoE dial-up.
      Online mode PPPoE dial-up mode.
      • Always online: The DCC attempts to dial the remote end immediately after the device starts. The dialing process is not triggered by data packets. If a connection cannot be established with the remote end, the DCC retries at an interval.

        This mode applies to the scenarios in which users are not charged based on traffic or time.

      • Disconnected after idle timeout (s): The device triggers the process of establishing a link only when there is data to be transmitted. When the time during which no traffic is transmitted on the link exceeds the timeout duration, the device disconnects the link to save traffic.

        This mode applies to the scenarios in which users are charged based on traffic or time.

        If this mode is used, the link idle time must be specified. The default link idle time is 120.

      Authentication mode Authentication mode for PPPoE dial-up.
      • PAP: Passwords are sent over links in plain text. After a PPP link is established, the authenticated device repeatedly sends the user name and password until the authentication finishes. This mode cannot ensure high security.

      • CHAP: a three-way handshake authentication protocol. In CHAP authentication, the authenticated device sends only the user name to the authenticating device. Compared with PAP, CHAP features higher security because passwords are not transmitted.
