aoe-interfaces - restrict aoe driver to specified network interfaces

aoe-interfaces [dev1] [dev2 ...]
aoe-interfaces -c

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.

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

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.
