[31] Calling-Station-Id

Use the following commands to manage information for the Calling-Station-Id RADIUS attribute.

• radius calling-station-format
• radius calling-station-delimiter
• radius include calling-station-id
• radius override calling-station-id remote-circuit-id

radius calling-station-format

• Use to specify the format of the Calling-Station-Id [31] attribute on a virtual router.
• For each field in angle brackets (<>) in the Calling-Station-Id formats, the virtual router supplies the actual value for your configuration, unless otherwise specified.
• To specify that the RADIUS client use the delimited format when the PPP user is terminated at the non-LNS E-series router, use the delimited keyword.
  • Format for ATM interfaces:
    <delimiter> <system name> <delimiter> <interface> <delimiter> <VPI> <delimiter> <VCI><delimiter>
  • Format for Ethernet interfaces:
    <delimiter> <system name> <delimiter> <interface> <delimiter> <VLAN>

    Where <interface> is one of the following items:

  • <port name>—The default setting
  • <VP description>—Appears if you use the atm vp-description command to assign a text description to an individual VP on an ATM interface
  • <VC description>—Appears if you use the atm atm1483 description command to assign a text description to VCs on an ATM 1483 subinterface and you use the atm1483 export-subinterface-description command to enable sending of VC interface descriptors to AAA
• To specify that the RADIUS client use a fixed format of up to 15 characters consisting of all ASCII fields, use the fixed-format keyword. The maximum number of characters for each field is shown in square brackets ([ ]).
  • Format for ATM interfaces:
    <system name [4]> <slot [2]> <port [1]> <VPI [3]> <VCI [5]>
  • Format for Ethernet interfaces:
    <system name [4]> <slot [2]> <port [1]> <VLAN [8]>
  • Format for serial interfaces:
    <system name [4]> <slot [2]> <port [1]> <0 [8]>

    Where the final 8-byte field is always 0 (zero).

  • In the case of PPP terminated at the LNS, the Calling-Station-Id attribute is based on the received L2TP calling number AVP.
• To specify that the RADIUS client use 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, use the fixed-format-adapter-embedded keyword. The maximum number of characters for each field is shown in square brackets ([ ]).
  • Format for ATM interfaces:
    <system name [4]> <slot [1]> <adapter [1]> <port [1]>
    <VPI [3]> <VCI [5]>
  • Format for Ethernet interfaces:
    <system name [4]> <slot [1]> <adapter [1]> <port [1]>
    <VLAN [8]>
  • Format for serial interfaces:
    <system name [4]> <slot [1]> <adapter [1]> <port [1]> <0 [8]>

    Where the final 8-byte field is always 0 (zero).

  • For E120 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 or 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 ERX-7xx models, ERX-14xx models, and ERX-310 routers, <adapter> is always shown as 0 (zero).
  • Slot numbers 0 through 16 are shown as ASCII characters in the 1-byte slot field according to the following translation:

    Slot Number	ASCII Character	Slot Number	ASCII Character
    0	0	9	9
    1	1	10	A
    2	2	11	B
    3	3	12	C
    4	4	13	D
    5	5	14	E
    6	6	15	F
    7	7	16	G
    8	8	–	–

    For example, slot 16 is shown as the ASCII character uppercase G.

• To specify that the RADIUS client use 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, use the fixed-format-adapter-new-field keyword. The maximum number of characters for each field is shown in square brackets ([ ]).

  Note: You must use this command with the fixed-format-adapter-new-field keyword when you configure the format of the Calling-Station-ID attribute on routers that have line modules that support more than seven physical ports.

  • Format for ATM interfaces:
    <system name [4]> <slot [2]> <adapter [1]> <port [2]>
    <VPI [3]> <VCI [5]>
  • Format for Ethernet interfaces:
    <system name [4]> <slot [2]> <adapter [1]> <port [2]>
    <VLAN [8]>
  • Format for serial interfaces:
    <system name [4]> <slot [2]> <adapter [1]> <port [2]> <0 [8]>

    Where the final 8-byte field is always 0 (zero).

  • For E120 and E320 routers, <adapter> is the number of the bay in which the I/O adapter (IOA) resides, either 0 or 1. For ERX-7xx models, ERX-14xx models, and ERX-310 routers, <adapter> is always shown as 0 (zero).
  • Slot numbers 0 through 16 are shown as integers in the 2-byte slot field.
• To specify that the format of the Calling-Station-Id [31] attribute include a 4-byte stacked VLAN (S-VLAN) ID for Ethernet interfaces when the RADIUS client uses the fixed-format, fixed-format-adapter-embedded, or fixed-format-adapter-new-field format, use the fixed-format stacked, fixed-format-adapter-embedded stacked, or fixed-format-adapter-new-field stacked keywords, respectively. The maximum number of characters for each field is shown in square brackets ([ ]).

  Note: The use of the stacked keyword is not supported for VLAN subinterfaces based on agent-circuit-identifier information, otherwise known as ACI VLANs. When you issue the radius calling-station-format fixed-format stacked, radius calling-station-format fixed-format-adapter-embedded stacked, or radius calling-station-format fixed-format-adapter-new-field stacked command for an ACI VLAN, the values that appear in the 4-byte S-VLAN ID and 4-byte VLAN ID fields are incorrect.

  • Format for Ethernet interfaces that use fixed-format stacked:
    <system name [4]> <slot [2]> <port [1] <S-VLAN [4] <VLAN [4]>
  • Format for Ethernet interfaces that use fixed-format-adapter-embedded stacked:
    <system name [4]> <slot [1]> <adapter [1]><port [1] <S-VLAN [4] <VLAN [4]>
  • Format for Ethernet interfaces that use fixed-format-adapter-new-field stacked:
    <system name [4]> <slot [2]> <adapter [1]><port [2] <S-VLAN [4] <VLAN [4]>

    By default, these formats do not include the S-VLAN ID unless you specify the optional stacked keyword. If you include the stacked keyword, the S-VLAN ID is displayed in decimal format in the range 0–4095.

    The S-VLAN ID field in the Calling-Station-Id [31] attribute is set to 0 (zero) under the following conditions:

  • You do not specify the optional stacked keyword.
  • You specify the optional stacked keyword but the Ethernet interface does not have an S-VLAN ID.
• Attribute 31, Calling-Station-Id, is used with Attribute 30, Called-Station-Id, in a standard way when the router is the LNS and the LAC is a dial-up LAC (not an E-series router). When the LNS receives the Calling-Station-Id and Called-Station-Id AVPs, the router includes the values as they are, with no format changes in the RADIUS messages.
• Example 1

  host1(config)#radius calling-station-format fixed-format

  For example, when you configure this Calling-Station-Id format on an E320 router for an ATM interface on system name eastern, slot 14, adapter 1, port 2, VCI 3, and VPI 4, the virtual router displays the format in ASCII as ‘14’ ‘2’ ‘003’ ‘00004’. The adapter number does not appear in this format.

• Example 2

  host1(config)#radius calling-station-format fixed-format-adapter-embedded

  For example, when you configure this Calling-Station-Id format on an E320 router for an ATM interface on system name eastern, slot 14, adapter 1, port 2, VCI 3, and VPI 4, the virtual router displays the format in ASCII as ‘E’ ‘1’ ‘2’ ‘003’ ‘00004’.

• Example 3

  host1(config)#radius calling-station-format fixed-format-adapter-new-field

  For example, when you configure this Calling-Station-Id format on an E320 router for an ATM interface on system name eastern, slot 14, adapter 1, port 2, VCI 3, and VPI 4, the virtual router displays the format in ASCII as ‘14’ ‘1’ ‘02’ ‘003’ ‘00004’.

• Example 4

  host1(config)#radius calling-station-format fixed-format-adapter-new-field stacked

  For example, when you configure this Calling-Station-Id format on an E320 router for an Ethernet interface on system name western, slot 4, adapter 1, port 3, S-VLAN ID 8, and VLAN ID 12, the virtual router displays the format in ASCII as ‘west’ ‘04’ ‘1’ ‘03’ ‘0008’ ‘0012’.

• Use the no version to restore the default Calling-Station-Id format, delimited.
• See radius calling-station-format

radius calling-station-delimiter

• Use to specify the Calling-Station-Id attribute’s delimiter for DSL PPP users.
• The delimiter is one special character you select to set off items in the Calling-Station-Id’s definition (for example, # or %).
• See radius calling-station-delimiter

• Example

  host1(config)#radius calling-station-delimiter &

• Use the no version to remove the delimiter.

radius include calling-station-id

• Use to include the Calling-Station-Id attribute in Access-Request, Acct-Start, or Acct-Stop messages.
• You can control inclusion of the attribute by enabling or disabling this command.
• See radius include

• Example

  host1(config)#radius include calling-station-id acct-start disable

• Use the no version to restore the default, enable.

radius override calling-station-id remote-circuit-id

• Use to configure RADIUS to override the standard use of the Calling-Station-Id attribute and instead use the remote circuit ID transmitted from a DSLAM device.
• See radius override calling-station-id remote-circuit-id

• Example

  host1(config)#radius override calling-station-id remote-circuit-id

• Use the no version to restore the default Calling-Station-ID value, which is the telephone number from which the call originated.
