Underlying Interface

Name of the PPPoE underlying logical interface.

Service Name Table

Name of the service name table.

Dynamic Profile

Name of the dynamic profile that was used to create this interface. If the interface was statically created, then the value is none.

Index

Index number of the logical interface, which reflects its initialization sequence.

State

Origin of the logical interface: Static or Dynamic. Indicates whether the interface was statically or dynamically created.

Operational States

Fields in this block are actual operational values rather than simply the configured values. The operational values can be the result of RADIUS-initiated changes.

Max Sessions

Maximum number of PPPoE logical interfaces that can be activated on the underlying interface. When this number of logical interfaces has been established, all subsequent PPPoE Active Discovery Initiation (PADI) packets are dropped and all subsequent PPPoE Active Discovery Request (PADR) packets trigger PPPoE Active Discovery Session (PADS) error responses.

Max Sessions VSA Ignore

Whether the router is configured to ignore (clear) the PPPoE maximum session value returned by RADIUS in the Max-Clients-Per-Interface Juniper Networks VSA [26-143] and restore the PPPoE maximum session value on the underlying interface to the value configure with the max-sessions statement: Off (default) or On.

Active Sessions

Number of active PPPoE sessions on the underlying interface. If a dynamic profile is listed, then it is the number of active PPPoE sessions on the underlying interface that are using this profile. The Active Sessions value must not exceed the Max Sessions value.

Agent Circuit Identifier

Whether the underlying interface is configured with the agent-circuit-identifier statement to enable creation of autosensed dynamic VLAN subscriber interfaces based on agent circuit identifier (ACI) information.

Autosensing indicates that creation of ACI-based dynamic VLAN interfaces is enabled on the underlying interface. If creation of ACI-based dynamic VLANs is not configured on the underlying interface, this field does not appear.

Line Identity

Whether the underlying interface is configured with the line-identity statement to enable creation of autosensed dynamic VLAN subscriber interfaces based on the specified trusted option: ACI, ARI, both, or neither.

Autosensing indicates that creation of ALI-based dynamic VLAN interfaces is enabled on the underlying interface. If creation of ALI dynamic VLANs based on trusted options is not configured on the underlying interface, this field does not appear.

Duplicate Protection

State of PPPoE duplicate protection: On or Off. When duplicate protection is configured for the underlying interface, a dynamic PPPoE logical interface cannot be activated when an existing active logical interface is present for the same PPPoE client. The uniqueness of the PPPoE client is determined by the client's MAC address.

Short Cycle Protection

State of PPPoE short cycle protection: mac-address, circuit-id, or Off. Enabling short cycle protection, also known as PPPoE lockout, on the PPPoE underlying interface temporarily prevents (locks out) a failed or short-lived (short-cycle) PPPoE subscriber session from reconnecting to the router for a default or configurable period of time. PPPoE client sessions are identified by their unique media access control (MAC) source address or agent circuit identifier (ACI) value.

Direct Connect

State of the configuration to ignore DSL Forum VSAs: On or Off. When configured, the router ignores any of these VSAs received from a directly connected CPE device on the interface.

AC Name

Name of the access concentrator.

PacketType

Number of packets sent and received during the PPPoE session, categorized by packet type and packet errors:

• 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 Termination 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 performing 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 packets—Malformed or short packets that caused the packet handler to discard the frame as unreadable.

• Unknown packets—Unrecognized packets.

Lockout Time (sec)

The PPPoE lockout time range, the number of PPPoE clients in lockout condition, and the number of PPPoE clients in a lockout grace period if Short Cycle Protection is enabled (On):

• Min—Minimum lockout time, in seconds, configured on the PPPoE underlying interface.

• Max—Maximum lockout time, in seconds, configured on the PPPoE underlying interface.

• Total clients in lockout—Number of PPPoE clients currently undergoing lockout.

• Total clients in lockout grace period—Number of PPPoE clients currently in a lockout grace period. A lockout grace period occurs when the time between lockout events is greater than either 15 minutes or the maximum lockout time.

Client Address

MAC source address of the PPPoE client.

Current

Current lockout time, in seconds; displays 0 (zero) if the PPPoE client is not undergoing lockout.

Elapsed

Time elapsed into the lockout period, in seconds; displays 0 if the PPPoE client is not undergoing lockout

Next

Lockout time, in seconds, that the router uses for the next lockout event; displays a nonzero value if the PPPoE client is currently in a lockout grace period.
