DLS Dynamic Load Sharing. Dynamic distribution of traffic over available
paths. Allows for redistribution when an Fx_Port or E_Port comes up
or down.
Domain ID As applies to some switches, a unique number between 1 and 239
that identifies the switch to the fabric.
E_D_TOV Error Detect Time-out Value. Time allowed for round-trip

minimum time an L_Port waits for sequence completion before
initiating recovery. See also R_A_TOV.

E_Port Expansion Port. A switch port that has the ability to connect to a
similar port on another switch, allowing creation of an interswitch
link. See also ISL.
EE_Credit End-to-end credit. The number of receive buffers allocated by
recipient port to originating port. Used by Class 1 and 2 services to
manage exchange of frames across intervening ports in fabric. See
also End-to-end flow control, BB_Credit.
Enabled configuration The currently enabled zone configuration. Only one configuration
can be enabled at a time. See also Defined configuration, Zone

loss of synchronization, or loss of signal. See also Loop failure.
Exchange As applies to fibre channel, a communication session between
