|
Interface
|
Name of the PPPoE interface.
|
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 Services Router 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, fe-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 Services Router can
support. The default is 256 sessions.
|
|
|
PADI Resend Timeout
|
Initial time, (in seconds) the Services Router 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 Services Router 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 Services Router 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 Services Router 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.
