Table 18: show dhcp server binding Output Fields (continued)
Level of OutputField DescriptionField Name
detailState 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 DOWN state, beginning
with a liveness detection failure, and ending with the
deletion of the client binding. The DOWN state is reported
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 state.
• 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 state.
• WENT_DOWN—State is functionally equivalent to the
DOWN state. A liveness detection session that was
previously in an UP state has transitioned to a DOWN
state implying a liveness detection failure.
The WENT_DOWN state applies to the internal
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.
