Configuration Notes
The following information describes provisioning caveats:
• Chassis slots must be preprovisioned to accept specific line card types.
• Line cards must be preprovisioned to accept specific MDA types.
If a card or MDA type is installed in a slot provisioned for a different type, the card will
not initialize.
• A card and MDA installed in an unprovisioned slot remain administratively and
operationally down until the slot, card type, MDA slot, and MDA type is specified.
• Ports cannot be provisioned until the slot, card and MDA type are specified.
• cHDLC does not support HDLC windowing features, nor other HDLC frame types such
as S-frames.
• cHDLC operates in the HDLC Asynchronous Balanced Mode (ABM) of operation.
• APS configuration rules:

A physical port (either working or protection) must be shutdown before
it can be removed from an APS group port.

For a single-chassis APS group, a working port must be added first. Then a protection
port can be added or removed at any time.

A protection port must be shutdown before being removed from an APS group.

A path cannot be configured on a port before the port is added to an APS group.

A working port cannot be removed from an APS group until the APS port path is
removed.

When ports are added to an APS group, all path-level configurations are available
only on the APS port level and configuration on the physical member ports are
blocked.

For APS-protected bundles, all members of a working bundle must reside on the
working port of an APS group. Similarly all members of a protecting bundle must
reside on the protecting circuit of that APS group.
