Field Description
State of the liveness detection status for a subscriber's
Bidirectional Forwarding Detection (BFD) protocol session:
NOTE: This output field displays status only when liveness
detection has been explicitly configured for a subscriber
and the liveness detection protocol is actively functioning
for that subscriber.
DOWN —Liveness detection has been enabled for a
subscriber but the broadband network gateway (BNG)
detects that the liveness detection session for the BFD
protocol is in the DOWN state.
A liveness detection session that was previously in an
UP state has transitioned to a
with a liveness detection failure, and ending with the
deletion of the client binding. The
only during this transition period of time.
UNKNOWN —Liveness detection has been enabled for a
subscriber but the actual liveness detection state has
not yet been determined.
The UNKNOWN state is reported after a DHCP subscriber
initially logs in while the underlying liveness detection
protocol handshake, such as BFD, is still processing and
the BFD session has not yet reached the
UP —Liveness detection has been enabled for a
subscriber, and the BNG and the subscriber or client have
both determined that the liveness detection session for
the BFD protocol is in the UP
WENT_DOWN —State is functionally equivalent to the
state. A liveness detection session that was
DOWN
previously in an state has transitioned to a
UP
state implying a liveness detection failure.
The state applies to the internal
WENT_DOWN
distribution of the liveness detection mechanism
between the Junos DHCP Daemon for Subscriber
Services (JDHCPd), the BFD plug-in within the
Broadband Edge Subscriber Management Daemon
(BBE-SMGD), and the Packet Forwarding Engine.
Internally generated name of the dynamic agent circuit
identifier (ACI) interface set.

Identifier of the dynamic ACI interface set entry in the
session database.
DHCP client profile name.
