# aoe-interfaces(8)

restrict aoe driver to specified network interfaces

## 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.
