.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-e\ \fIetherXX'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 p ,
.LR t ,
.LR g ,
.LR m ,
or
.LR k
to specify a customary
.I binary
multiplier.
.TP
.BI -a " m.n"
Specify the shelf and slot (or major and minor) address of the target.
Valid shelf numbers are between 0 and 65534.  Valid slots are 0-255.
.TP
.BI -c " s"
Set the AoE config string to
.IR s .
.TP
.BI -e " ether"
Listen to the network port
.IR ether.
Multiple ports may be specified.

.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.
