Glossary
domain ID
Number (1 through 31) that uniquely identifies a Switch in a multiswitch fabric. A distinct
domain ID is automatically allocated to each Switch in the fabric by the principal Switch.
domain name service (DNS)
See DNS name.
E_D_TOV
See error detect time-out value.
E_Port
See expansion port.
Embedded Web Server
Administrators or operators with a browser-capable PC and Internet connection can monitor
and manage a Director or Edge Switch through an Embedded Web Server interface. The
interface provides a GUI similar to Product Manager applications, and supports Director and
Switch configuration, statistics monitoring, and basic operation.
error message
Indication that an error has been detected. See also information message; warning message.
error detect time-out value (E_D_TOV)
User-specified value that defines the time a Director or Edge Switch waits for an expected
response before declaring an error condition.
Ethernet
A widely implemented local area network (LAN) protocol that uses a bus or star topology and
serves as the basis for the IEEE 802.3 standard, which specifies the physical and software
layers. Baseband LAN allows multiple station access to the transmission medium at will
without prior coordination and which avoids or resolves contention.
Ethernet hub
A customer-supplied device used to LAN-connect the HAFM server and managed Directors or
Edge Switches.
event code
Error code that provides the operator with information concerning events that indicate
degraded operation or failure of a Director or Edge Switch.
event log
Record of significant events that have occurred at the Director or Edge Switch, such as FRU
failures, degraded operation, and port problems.
expansion port (E_Port)
Physical interface on a Fibre Channel Switch within a fabric, that attaches to an expansion port
(E_Port) on another Fibre Channel Switch to form a multiswitch fabric.
