Configuration notes

The following information describes provisioning restrictions:

If a card or MDA type is installed in a slot provisioned for a different type, the card does not initialize.
A card or MDA installed in an unprovisioned slot remains administratively and operationally down until the card type and MDA 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 shut down 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 shut down 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.
