.TH aoe-interfaces 8
.SH NAME
aoe-interfaces \- restrict aoe driver to specified network interfaces
.SH SYNOPSIS
.nf
.B aoe-interfaces [dev1] [dev2 ...]
.B aoe-interfaces -c
.fi
.SH DESCRIPTION
The
.I aoe-interfaces
command tells the aoe driver to ignore ATA over Ethernet (AoE) traffic
on all but the specified network interfaces. It is analogous to the
\fIaoe_iflist\fP module load option.
.PP
If neither the \fIaoe_iflist\fP module load option nor the
\fIaoe-interfaces\fP command are used, the aoe driver will use any
network interface for AoE traffic. Using \fIaoe-interfaces\fP to
limit AoE to only trusted networks prevents the case where a rogue AoE
target appears on a public network, diverting data from the legitimate
AoE target. Such an imposter target effectively corrupts the data on
the legitimate target.
.PP
If the aoe driver is a module, then calling
.I aoe-interfaces
without arguments will display the current interfaces list. If it
hasn't been set then the output will be blank.
.PP
It's good to run the
.I aoe-discover
command after setting the AoE interfaces list.
.SH OPTIONS
.TP
\fB-c\fP
The \fB-c\fP flag will clear the interface access list, permitting any interface to be used.
.SH EXAMPLE
In this example, the root user on a host named
.I nai
loads the aoe module with only eth0 allowable for AoE traffic. After
remembering that shelf 7 is on eth3, this
sysadmin uses
.I aoe-interfaces
to add eth3 to the list of allowable network interfaces and then
calls
.I aoe-discover
to ask the aoe driver to look for new AoE devices.
