Card, Adapter Card, and Port Command Reference
encap-type
Syntax encap-type {atm}
no encap-type
Context config>port>sonet-sdh>path
Description This command configures the encapsulation method used to distinguish customer traffic on an access
SONET/SDH channel sub-port (encap-type is only required when configuring a SONET/SDH path
for access mode).
When encap-type is atm, the
When encap-type is atm, ATM sub-layer verification specified in GR-1248-CORE, Generic
Requirements for Operations of ATM Network Elements, is automatically enabled. The result of the
verification includes:
The no form of this command restores the default.
Default
atm
Parameters atm — specifies that the encapsulation on the port is ATM
mtu
Syntax mtu mtu
no mtu
Context config>port>sonet-sdh>path
Description This command configures the maximum payload MTU size for a SONET/SDH port.
When encap-type is atm, the path MTU value cannot be changed. Refer to the 7705 SAR OS
Services Guide for information on configuring the path MTU.
The no form of this command restores the default values.
Default

• Out of Cell Delineation (OCD) event count — the OCD event count is described in RFC
2515, Definitions of Managed Objects for ATM Management. Multiple events occurring
within 1 second will be counted as one event for ATM and ASAP adapter cards as a result of
a hardware limit.
• Loss of Cell Delineation (LCD) defect/alarm — the LCD defect/alarm is defined in RFC
2515, Definitions of Managed Objects for ATM Management. When a path is in an LCD
defect state, the path's operational status is down. When a path exits the LCD state, the
path's operational status will change to up (assuming nothing else causes the path to stay
down). A trap is raised to indicate the LCD status change, and a Path Remote Defect
Indicator (PRDI) is sent to indicate the defect to the remote end.
