which can cause packets to be dropped even when the queue is not congested or the
port is not oversubscribed.

Exporting active flow monitoring version 9 packets from CSE2000 to PTX Series
routers—Starting with Junos OS Release 13.3R4, active flow monitoring version 9
records created by CSE2000 are sent back to PTX Series Routers on the 10-Gigabit
Ethernet interface. The PTX Series routers then forward the version 9 flow records to
the version 9 flow server.
In releases before Junos OS Release 13.3R4, the version 9 records are sent to the version
9 flow server by means of a separate external collector port. PR985729
Routing Protocols
•
Modification to the default BGP extended community value—Junos OS modifies the
default BGP extended community value used for MVPN IPv4 VRF route import
(RT-import) to the IANA-standardized value. The behavior of the mvpn-iana-rt-import
statement is now the default. The mvpn-iana-rt-import statement has been deprecated;
we recommend that you remove it from configurations.
User Interface and Configuration
•
User-defined identifiers using the reserved prefix junos- now correctly cause a commit
error in the CLI (PTX Series)—Junos OS reserves the prefix junos- for the identifiers of
configurations defined within the junos-defaults configuration group. User-defined
identifiers cannot start with the string junos-. If you configured user-defined identifiers
using the reserved prefix through a NETCONF or Junos XML protocol session, the
commit would correctly fail. Prior to Junos OS Release 13.3, if you configured
user-defined identifiers through the CLI using the reserved prefix, the commit would
incorrectly succeed. Junos OS Release 13.3 and later releases exhibit the correct
behavior. Configurations that currently contain the reserved prefix for user-defined
identifiers other than junos-defaults configuration group identifiers now correctly result
in a commit error in the CLI.
•
Change in show version command output (PTX Series)—Beginning in Junos OS
Release 13.3, the show version command output includes the new Junos field that
displays the Junos OS version running on the device. This new field is in addition to the
list of installed sub-packages running on the device that also display the Junos OS
version number of those sub-packages. This field provides a consistent means of
identifying the Junos OS version, rather than extracting that information from the list
of installed sub-packages.
In Junos OS Release 13.2 and earlier, the show version command does not have the
single Junos field in the output that displays the Junos OS version running on the device.
