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.
- -c
- 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.
