Interfaces |
|
Interface
|
Name of the PPPoE interface.
(See the interface naming conventions in the JUNOS Software Interfaces and Routing Configuration Guide.)
|
Click the interface name to display PPPoE information for the
interface.
|
|
State
|
State of the PPPoE session on the interface.
| |
|
Session ID
|
Unique session identifier for the PPPoE session.
|
To establish a PPPoE session, first the device acting
as a PPPoE client obtains the Ethernet address of the PPPoE server
or access concentrator, and then the client and the server negotiate
a unique session ID. This process is refereed as PPPoE active discovery
and is made up of four steps: initiation, offer, request, and session
confirmation. The access concentrator generates the session ID for
session confirmation and sends it to the PPPoE client in a PPPoE Active
Discovery Session-Confirmation (PADS) packet.
|
|
Service Name
|
Type of service required from the access concentrator.
|
Service Name identifies the type of service provided by the access concentrator,
such as the name of the Internet service provider (ISP), class, or
quality of service.
|
|
Configured AC Name
|
Configured access concentrator name.
| |
|
Session AC Names
|
Name of the access concentrator.
| |
|
AC MAC Address
|
Media access control (MAC) address of the access concentrator.
| |
|
Session Uptime
|
Number of seconds the current PPPoE session has been running.
| |
|
Auto-Reconnect Timeout
|
Number of seconds to wait before reconnecting after a PPPoE
session is terminated.
| |
|
Idle Timeout
|
Number of seconds a PPPoE session can be idle without disconnecting.
| |
|
Underlying Interface
|
Name of the underlying logical Ethernet or ATM interface on
which PPPoE is running—for example, ge-0/0/0.1.
| |
| PPPoE
Statistics |
|
Active PPPoE Sessions
|
Total number of active PPPoE sessions.
| |
|
Packet Type
|
Packets sent and received during the PPPoE session, categorized
by packet type and packet error:
-
PADI—PPPoE Active Discovery Initiation
packets.
-
PADO—PPPoE Active Discovery Offer packets.
-
PADR—PPPoE Active Discovery Request packets.
-
PADS—PPPoE Active Discovery Session-Confirmation
packets.
-
PADT—PPPoE Active Discovery Terminate packets.
-
Service Name Error—Packets for which the
Service-Name request could not be honored.
-
AC System Error—Packets for which the access concentrator experienced
an error in processing the host request. For example, the host had
insufficient resources to create a virtual circuit.
-
Generic Error—Packets that indicate an
unrecoverable error occurred.
-
Malformed Packet—Malformed or short packets
that caused the packet handler to disregard the frame as unreadable.
-
Unknown Packet—Unrecognized packets.
| |
|
Sent
|
Number of the specific type of packet sent from the PPPoE client.
| |
|
Received
|
Number of the specific type of packet received by the PPPoE
client.
| |
|
Timeout
|
Information about the timeouts that occurred during the PPPoE
session.
- PADI—Number of timeouts that occurred for the PADI
packet.
- PADO—Number of timeouts that occurred for the PADO
packet. (This value is always 0 and is not supported.
- PADR—Number of timeouts that occurred for the PADR
packet.
| |
|
Sent
|
Number of the timeouts that occurred for PADI, PADO, and PADR
packets.

|
Maximum Sessions
|
Maximum number of active PPPoE sessions the device can
support. The default is 256 sessions.
| |
|
PADI Resend Timeout
|
Initial time, (in seconds) the device waits to
receive a PADO packet for the PADI packet sent—for example, 2 seconds. This timeout doubles for each successive PADI packet
sent.
|
The PPPoE Active Discovery Initiation (PADI) packet is sent
to the access concentrator to initiate a PPPoE session. Typically,
the access concentrator responds to a PADI packet with a PPPoE Active Discovery Offer
(PADO) packet. If the access concentrator does not send a PADO packet, the device sends
the PADI packet again after timeout period is elapsed. The PADI Resend
Timeout doubles for each successive PADI packet sent. For example,
if the PADI Resend Timeout is 2 seconds, the second PADI
packet is sent after 2 seconds, the third after 4 seconds, the fourth after 8 seconds, and so on.
|
|
PADR Resend Timeout
|
Initial time (in seconds) the device waits to receive
a PADS packet for the PADR packet sent. This timeout doubles for each
successive PADR packet sent.
|
The PPPoE Active Discovery Request (PADR) packet is sent to
the access concentrator in response to a PADO packet, and to obtain
the PPPoE session ID. Typically, the access concentrator responds to a PADR packet
with a PPPoE Active Discovery Session-Confirmation (PADS) packet,
which contains the session ID. If the access concentrator does not send a PADS packet,
the device sends the PADR packet again after the PADR
Resend Timeout period is elapsed. The PADR Resend Timeout doubles
for each successive PADR packet sent.
|
|
Maximum Resend Timeout
|
Maximum value (in seconds) that the PADI or PADR resend timer
can accept—for example, 64 seconds. The maximum value is 64.
| |
|
Maximum Configured AC Timeout
|
Time (in seconds), within which the configured access concentrator must respond.
