To specify ATM children within a container interface, use the

level.
To configure a container interface, including its children, use the
options at the

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
indicates if all fabric planes are down, and the FPCs will reboot if any fabric planes do
not come up in 2 minutes.
An ERRMSG indicates the reason for FPC reboot on fabric connectivity loss.
The chassisd daemon traces when an FPC comes online, but a PIC attach is not done
because no fabric plane is present.
A CLI warning that the FPCs will reboot is issued when the last fabric plane is taken
offline.
