.SH DESCRIPTION
For each
.I file
specified,
.I vblade
serves it as an AoE (ATA-over-Ethernet) target via
the specified interfaces.  The default interface is
.BR /net/ether0 .
Since AoE uses raw Ethernet frames, the target is
only visible on the local ethernet segment.
.PP
All target-related options are reset for each
.IR file .
.SS Options
.TP \w'\fL-m\ \fIeamaskXX'u
.B -i
Initialize the configuration header in 
.IR file .
All previous configuration information is lost.  Without this option,
configuration is read from
.I file
and command like options override previous settings.
.TP
.B -r
Raw.  Do not use a configuration header.  This is useful when
exporting a device or file not generally exported by
.IR vblade .
.TP
.BI -s " n"
The exported target will have size
.IR n ,
rather than the available space in the target.  A size may end in

.LR t ,
.LR g ,
.LR m ,
or
.LR k
to specify a
.I binary
multiplier.
.TP
.BI -a " m.n"

Valid shelf numbers are between 0 and 65534.  Valid slots are 0-255.

respond to targets in the mask set.  Ignore all other requests.

.SH BUGS
Security depends on control of the local Ethernet segment.  It may be
unwise to serve AoE on a segment bridged to a wireless network.
