New Features in Junos OS Release 10.4 for M Series, MX Series, and T Series Routers
You will need to bring the SIBs online after determining why the SIBs were not online.
When the first SIB goes online, and link training with the FPCs completes, the interfaces
will be created.
Fabric down signaling to neighboring routers functionality is available by default, and
no user configuration is required to enable it.
No new CLI commands or alarms are introduced for this feature. Alarms are already
implemented for when the SIBs are not online.

New enterprise-specific MIB to support digital optical monitoring (MX960, MX480,
MX240, and 10-Gigabit Ethernet LAN/WAN PIC with XFP on T640 and T1600
routers)—Junos OS Release 10.4 introduces
enterprise-specific MIB to extend MIB support for digital optical monitoring.
JUNIPER-DOM-MIB
supports the SNMP Get request for statistics and SNMP Trap
notifications for alarms.
is part of the
JUNIPER-DOM-MIB
The following MIB objects are supported by
monitoring:
jnxDomCurrentTable
jnxDomAlarmSet
jnxDomAlarmCleared

Logging improvements—You can now control logging speed at the interface level. To
rate-limit the syslogs generated from a service PIC, include the
statement at the
[edit interfaces interface-name services-options syslog]
level. This option configures the maximum number of syslog messages per second
that can formatted and sent from the PIC to either the Routing Engine (local) or to an
external server (remote). The default rates are 10,00 for the Routing Engine and 200,00
for an external server.

Support for SONET/SDH OC48/STM16 Enhanced IQ (IQE) PIC with SFP (M320,
MX240, MX480, MX960, T640 and T1600 routers) Supports a 4-port SONET/SDH
OC48 Enhanced IQ (IQE) PIC (Type 3) with per data-link connection identifier (DLCI)
queuing. Supported FPCs include T640-FPC3-ES, M320-FPC3-E3, and MX-FPC3.
Class of service (CoS) enables enhanced egress queuing, buffering, and traffic shaping.
CoS supports eight queues per logical interface, a per-unit scheduler, and two shaping
rates: a Committed Information Rate (CIR) and Peak Information Rate (PIR) per
data-link connection identifier (DLCI). Other CoS features include, but are not restricted
to, sharing of excess bandwidth among logical interfaces, five levels of priorities
(including Strict High), ingress behavior aggregate (BA) classification, queue rate-limit
policer, ingress rewrite, egress rewrite, and a forwarding class to queue remapping per
DLCI.
