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
                  e7.4            eth3              up

                  e7.6            eth3              up
                  e7.7            eth3              up
                  e7.8            eth3              up
                  e7.9            eth3              up
                 e10.9            eth0              up
