    Profile Characteristics

    Currently, profiles support bridged Ethernet, IP, IPv6, L2TP, Multilink PPP, PPP, PPPoE, and VLANs. You create a profile with a specific set of characteristics. You then assign the profile to multiple interfaces instead of creating separate interfaces with identical attributes. After you create a profile, you can assign it to static ATM 1483, static PPP, or static VLAN major interfaces on different devices.

    Bridged Ethernet Characteristics

    A profile can contain the following bridged Ethernet characteristic:

    • mtu—Sets the maximum allowable size, in bytes, of the MTU for dynamic bridged Ethernet interfaces

    • initiate-ipv6—Initiates IPv6 for passive clients
    • ipcp lockout—Terminates an invalid subscriber entry and prevents additional Internet Protocol Control Protocol negotiations

    • ipcp-nego-duration—Configures the time period during which IPCP renegotiations for IPv4 addresses that the router or the provider edge device can receive from a subscriber are restricted
    • keepalive—Specifies a keepalive value, in seconds
    • log—Enables packet or state machine logging for any dynamic interfaces that use the profile
    • magic-number disable—Disables negotiation of the local magic number
    • magic-number ignore-mismatch—Causes the router to ignore a mismatch of the LCP peer magic number and retain the PPP connection when the peer has not negotiated an LCP magic number.

      Note: When the duplicate protection feature is enabled for PPPoE sessions that contain the IWF-Session DSL VSA (26–254) in the Point-to-Point Protocol over Ethernet Active Discovery Request packet sent from PPPoE clients to the access concentrator, multiple IWF PPPoE sessions that contain the same MAC address are still processed and can access network services until the maximum number of PPPoE sessions configured per major interface (configured using the pppoe sessions command) is reached.
