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.

              nai:~# modprobe aoe aoe_iflist="eth0"
              nai:~# aoe-stat
                 e10.9            eth0              up
              nai:~# aoe-interfaces eth0 eth3
              nai:~# aoe-discover
              nai:~# aoe-stat
                  e7.0            eth3              up
                  e7.1            eth3              up
                  e7.2            eth3              up
                  e7.3            eth3              up
