NAME
aoe-interfaces - restrict aoe driver to specified network interfaces
SYNOPSIS
aoe-interfaces [dev1] [dev2 ...]
aoe-interfaces -c
DESCRIPTION
The 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 aoe_iflist module load option.
If neither the aoe_iflist module load option nor the aoe-interfaces
command are used, the aoe driver will use any network interface for AoE
traffic. Using aoe-interfaces 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.
If the aoe driver is a module, then calling aoe-interfaces without
arguments will display the current interfaces list. If it hasn’t been
set then the output will be blank.
It’s good to run the aoe-discover command after setting the AoE
interfaces list.
OPTIONS
-c The -c flag will clear the interface access list, permitting any
interface to be used.
EXAMPLE
In this example, the root user on a host named nai loads the aoe module
with only eth0 allowable for AoE traffic. After remembering that shelf
7 is on eth3, this sysadmin uses aoe-interfaces to add eth3 to the list
of allowable network interfaces and then calls aoe-discover to ask the
aoe driver to look for new AoE devices.
