ATM OAM Commands
oam
Syntax oam
Context config>service>apipe>sap>atm
Description This command enables the context to configure OAM functionality for a PVCC delimiting a SAP.
The T1/E1 ASAP Adapter card and OC3/STM1 Adapter card support the generation of F4 (VP) and
F5 (VC) AIS cells when the Apipe service is operationally down. When the Apipe service is
operationally up, OAM cells are transported over the Apipe and are transparent to the 7705 SAR. This
capability is in accordance with ITU-T Recommendation I.610 - B-ISDN Operation and
Maintenance.
alarm-cells
Syntax [no] alarm-cells
Context config>service>apipe>sap>atm>oam
Description This command configures AIS/RDI fault management on a PVCC. Fault management allows PVCC
terminations to monitor and report the status of their connection by propagating fault information
through the network and by driving the PVCC's operational status.
The 7705 SAR Apipe does not support PVCC terminations. Instead, it allows OAM cells to be
transported transparently from end-to-end. When this command is enabled, AIS cells are generated
when an Apipe or corresponding SAP is operationally down.
The no command disables alarm-cells functionality for the Apipe. When alarm-cells functionality is
disabled, AIS cells are not generated as result of the Apipe or corresponding SAP going into the
operationally down state.
