NAME

6       aoe-interfaces - restrict aoe driver to specified network interfaces
7

SYNOPSIS

9       aoe-interfaces [dev1] [dev2 ...]
10       aoe-interfaces -c
11

DESCRIPTION

13       The aoe-interfaces command tells the aoe driver to ignore ATA over Eth‐
14       ernet (AoE) traffic on all but the specified network interfaces.  It is
15       analogous to the aoe_iflist module load option.
16
17       If  neither  the  aoe_iflist  module load option nor the aoe-interfaces
18       command are used, the aoe driver will use any network interface for AoE
19       traffic.   Using  aoe-interfaces  to limit AoE to only trusted networks
20       prevents the case where a rogue AoE target appears on a public network,
21       diverting data from the legitimate AoE target.  Such an imposter target
22       effectively corrupts the data on the legitimate target.
23
24       If the aoe driver is a  module,  then  calling  aoe-interfaces  without
25       arguments  will display the current interfaces list.  If it hasn't been
26       set then the output will be blank.
27
28       It's good to run the aoe-discover command after setting the AoE  inter‐
29       faces list.
30

OPTIONS

32       -c     The -c flag will clear the interface access list, permitting any
33              interface to be used.

EXAMPLE

36       In this example, the root user on a host named nai loads the aoe module
37       with only eth0 allowable for AoE traffic.  After remembering that shelf
38       7 is on eth3, this sysadmin uses aoe-interfaces to add eth3 to the list
39       of  allowable network interfaces and then calls aoe-discover to ask the
40       aoe driver to look for new AoE devices.
