application-specific integrated circuit
ASIC. An asynchronous transfer mode (ATM) local area network/ wide area network
(LAN/WAN) circuit using cell relay transport technology. ASICs are designed for a specific
application or purpose, such as implementing the lower-layer Fibre Channel protocol (FC-0).
They are particularly suited to sending video and audio information, as well as text. ASICs
differ from general-purpose devices such as memory chips or microprocessors.

Audit Log
Log summarizing actions (audit trail) made by the user. There are two types of Audit Logs: the
director or switch Audit Log, and the HAFM Audit Log.
(1) Director or switch Audit Log. Log displayed through the Product Manager application that
provides a history of all configuration changes made to an individual director or switch from
the respective Product Manager application, a simple network management protocol (SNMP)
management workstation, a Fibre Connection (FICON) or open systems host, or the
maintenance port. This information is useful for administrators and users. Contrast with
HAFM Audit Log. See also Event Log; Hardware Log; Link Incident Log; Threshold Alert
Log.
(2) See HAFM Audit Log.
