Configuring Operation, Administration, and Maintenance
This chapter describes the Operation, Administration, and M aintenance (OAM) implementation on the
ATM switch router.
Note This chapter provides advanced configuration instructions for the Catalyst8540 MSR,
Catalyst 8510MSR, and LightStream 1010 ATM switch routers. For complete descriptions of the
commands mentioned in this chapter, refer to the ATMSwitch Router Command Reference publication.

OAM Overview

OAM performs fault management and performance management functions at the ATM management
(M)-plane layer.
Note Current OAM implementation supports only the fault management function, which includes connectivity
verification and alarm surveillance.
The ATM switch router has full support for the following ATM OAM cell flows:
F4 flows—OAM information flows between network elements (NEs) used within virtual paths to
report an unavailable path or a virtual path (VP) that cannot be guaranteed.
F5 flows—OAM information flows between network elements (NEs) used within virtual
connections to report degraded virtual channel (VC) performanc e such as late arriving cells, lost
cells, and cell insertion problems.
