To configure SyncE, include the synchronization statement and its substatements at
the [edit chassis] hierarchy level.

Enhanced container interface allows ATM children for containers—M Series and T
Series routers with ATM2 PICs automatically copy the parent container interface
configuration to the children interfaces. Container interfaces do not go down during
APS switchovers, thereby shielding upper layers. This feature allows the various ATM
features to work over the container ATM for APS.
To specify ATM children within a container interface, use the container-list cin statement
and (primary | standby) option at the [edit interface at-fpc/pic/slot container] hierarchy
level.
To configure a container interface, including its children, use the cin statement and its
options at the [edit interface ci-n] hierarchy level.
Container ATM APS does not support inter-chassis APS. MLPPP over ATM CI is also
not supported.
[Network Interfaces]
•
Signaling neighboring routers of fabric down on T1600 and T640 routers—The
signaling of neighboring routers is supported when a T640 or T1600 router is unable
to carry traffic due to all fabric planes being taken offline for one of the following
reasons:
•
CLI or offline button pressed
•
Automatically taken offline by the SPMB due to high temperature.
•
PIO errors and voltage errors detected by the SPMB CPU to the SIBs.
The following scenarios are not supported by this feature:
•
All PFEs get destination errors on all planes to all destinations, even with the SIBs
staying online.
•
Complete fabric loss caused by destination timeouts, with the SIBs still online.
When chassisd detects that all fabric planes are down, the router reboots all FPCs in
the system. When the FPCs come back up, the interfaces will not be created again,
since all fabric planes are down.
Once you diagnose and fix the cause of all fabric planes going down, you must then
bring the SIBs back online. Bringing the SIBs back online brings up the interfaces.
Fabric down signaling to neighboring routers offers the following benefits:
•
FPCs reboot when the control plane connection to the Routing Engine times out.
•
Extends a simple approach to reboot FPCs when the dataplane blacks out.
When the router transitions from a state where SIBs are online or spare to a state where
there are no SIBs are online, then all the FPCs in the system are rebooted. An ERRMSG
