    Release Information

    Command introduced in JunosE Release 8.1.0.

    fixed-adapter-embedded, fixed-adapter-new-field, and stacked keywords added in JunosE Release 10.0.0.

    Description

    Configures the fallback format for the tunnel calling number to be passed by the E Series L2TP access concentrator (LAC) to the L2TP network server (LNS) in the L2TP Calling Number attribute value pair (AVP) 22 when the PPPoE agent circuit ID is null or unavailable. The fallback format is used only when the configured calling number format includes either or both of the agent-circuit-id and agent-remote-id suboptions. The no version restores the default fallback format, descriptive.

    Options

    • descriptive—Configures the fallback format in descriptive format that includes only interface information
    • fixed—Configures the fallback format in a fixed format of up to 15 characters consisting of all ASCII fields, similar to the fixed format of RADIUS attribute 31 (Calling-Station-Id):
      • Fallback format for ATM interfaces:
        systemName (up to 4 bytes) slot (2 bytes) port (1 byte) VPI (3 bytes)
        VCI (5 bytes)
      • Fallback format for Ethernet interfaces:
        systemName (up to 4 bytes) slot (2 bytes) port (1 byte) VLAN (8 bytes)
      • Fallback format for serial interfaces:
        systemName (up to 4 bytes) slot (2 bytes) port (1 byte) 0 (8 bytes)
      • In the case of PPP terminated from LNS, the Calling-Station-Id attribute is the value passed as the calling-station AVP.
    • fixed-adapter-embedded—Configures the fallback format in a fixed format of up to 15 characters consisting of all ASCII fields with a 1-byte slot field, 1-byte adapter field, and 1-byte port field:
      • Fallback format for ATM interfaces:
        systemName (up to 4 bytes) slot (1 byte) adapter (1 byte) port (1 byte)
        VPI (3 bytes) VCI (5 bytes)
      • Fallback format for Ethernet interfaces:
        systemName (up to 4 bytes) slot (1 byte) adapter (1 byte) port (1 byte)
        VLAN (8 bytes)
      • Fallback format for serial interfaces:
        systemName (up to 4 bytes) slot (1 byte) adapter (1 byte) port (1 byte)
        0 (8 bytes)
      • For E120 routers and E320 routers, adapter is the number of the bay in which the I/O adapter (IOA) resides, either 0 (representing the right IOA bay on the E120 router and the upper IOA bay on the E320 router) or 1 (representing the left IOA bay on the E120 router or the lower IOA bay on the E320 router). For ERX7xx models, ERX14xx models, and ERX310 routers, which do not use IOAs, adapter is always shown as 0.
      • Slot numbers 0 through 16 are shown as ASCII characters in the 1-byte slot field.
    • fixed-adapter-new-field—Configures the fallback format in a fixed format of up to 17 characters consisting of all ASCII fields with a 2-byte slot field, 1-byte adapter field, and 2-byte port field:
      • Fallback format for ATM interfaces:
        systemName (up to 4 bytes) slot (2 bytes) adapter (1 byte) port (2 bytes)
        VPI (3 bytes) VCI (5 bytes)
      • Fallback format for Ethernet interfaces:
        systemName (up to 4 bytes) slot (2 bytes) adapter (1 byte) port (2 bytes) VLAN (8 bytes)
      • Fallback format for serial interfaces:
        systemName (up to 4 bytes) slot (2 bytes) adapter (1 byte) port (2 bytes)
        0 (8 bytes)
      • For E120 routers and E320 routers, adapter is the number of the bay in which the IOA resides, either 0 or 1. For ERX7xx models, ERX14xx models, and ERX310 routers, which do not use IOAs, adapter is always shown as 0.
      • Slot numbers 0 through 16 are shown as integers in the 2-byte slot field.
    • stacked—Includes a 4-byte stacked VLAN (S-VLAN) ID in the fixed, fixed-adapter-embedded, and fixed-adapter-new-field fallback formats for Ethernet interfaces; by default, these formats do not include the S-VLAN ID unless you specify the optional stacked keyword:
      • Fallback format for Ethernet interfaces that use fixed:
        systemName (up to 4 bytes) slot (2 bytes) port (1 byte) S-VLAN (4 bytes) VLAN (4 bytes)
      • Fallback format for Ethernet interfaces that use fixed-adapter-embedded:
        systemName (up to 4 bytes) slot (1 byte) adapter (1 byte) port (1 byte) S-VLAN (4 bytes) VLAN (4 bytes)
      • Fallback format for Ethernet interfaces that use fixed-adapter-new-field:
        systemName (up to 4 bytes) slot (2 bytes) adapter (1 byte) port (2 bytes) S-VLAN (4 bytes) VLAN (4 bytes)
