Specifications

You can monitor various transport features like 24-hour bins and transport states by

using the transport-monitoring statement at the [edit interfaces] hierarchy level.

•

Support for active flow monitoring version 9 (PTX3000 routers with

CSE2000)—Starting with Junos OS Release 13.3R4, Carrier-Grade Service Engine

(CSE2000) supports active flow monitoring version 9 on PTX3000 routers.

The CSE2000 is tethered to a PTX3000 router to enable active flow monitoring version

9. Active flow monitoring version 9 supports IPv4, MPLS, and IPv6 templates to collect

a set of sampled flows and send the records to a specified host.

Network Management and Monitoring

•

Support for BFD over child links of AE or LAG bundle (cross-functional Packet

Forwarding Engine/kernel/rpd) (PTX Series)—Beginning in Junos OS Release 13.3,

BFD over child links of an AE or LAG bundle is supported on the PTX Series. This feature

provides a Layer 3 BFD liveness detection mechanism for child links of the Ethernet

LAG interface. You can enable BFD to run on individual member links of the LAG to

monitor the Layer 3 or Layer 2 forwarding capabilities of individual member links. These

micro BFD sessions are independent of each other despite having a single client that

manages the LAG interface. To enable failure detection for aggregated Ethernet

interfaces, include the bfd-liveness-detection statement at the [edit interfaces aex

aggregated-ether-options bfd-liveness-detection] hierarchy level.

[See Understanding Independent Micro BFD Sessions for LAG.]

Routing Protocols

•

Bidirectional PIM support (PTX5000)—Beginning with Junos OS Release 13.3,

bidirectional PIM is supported on the PTX5000. The following caveats are applicable

for the bidrectional PIM configuration on the PTX 5000:

•

The PTX5000 can be configured both as a bidirectional PIM rendezvous point and

the source node.

•

For the PTX5000, you can configure the auto-rp statement at the [edit protocols

pim rp] or the [edit routing-instances routing-instance-name protocols pim rp] hierarchy

level with the mapping option, but not the announce option.
