Описание (Description)
The ip macsec commands are used to configure transmit secure
associations and receive secure channels and their secure
associations on a MACsec device created with the ip link add
command using the macsec type.
Примеры (Examples)
Create a MACsec device on link eth0 (offload is disabled by default)
# ip link add link eth0 macsec0 type macsec port 11 encrypt on
Configure a secure association on that device
# ip macsec add macsec0 tx sa 0 pn 1024 on key 01 81818181818181818181818181818181
Configure a receive channel
# ip macsec add macsec0 rx port 1234 address c6:19:52:8f:e6:a0
Configure a receive association
# ip macsec add macsec0 rx port 1234 address c6:19:52:8f:e6:a0 sa 0 pn 1 on key 00 82828282828282828282828282828282
Display MACsec configuration
# ip macsec show
Configure offloading on an interface
# ip macsec offload macsec0 phy
Configure offloading upon MACsec device creation
# ip link add link eth0 macsec0 type macsec port 11 encrypt on offload mac
Примечание (Note)
This tool can be used to configure the 802.1AE keys of the
interface. Note that 802.1AE uses GCM-AES with a initialization
vector (IV) derived from the packet number. The same key must not
be used with the same IV more than once. Instead, keys must be
frequently regenerated and distributed. This tool is thus mostly
for debugging and testing, or in combination with a user-space
application that reconfigures the keys. It is wrong to just
configure the keys statically and assume them to work
indefinitely. The suggested and standardized way for key
management is 802.1X-2010, which is implemented by
wpa_supplicant.
