Q. Do the Cisco Catalyst 3750-X and 3560-X Series Switches support the Cisco
A. Cisco TrustSec is an end-to-end solution, and the Catalyst 3750-X and 3560-X
Series include support for it. At first customer shipment, encryption will be
supported only on the user ports, along with support for Security Group Tag
(SGT) Exchange Protocol (SXP). No hardware tagging is supported at this time.
Q. What hardware encryption is included in the Cisco Catalyst 3750-X and 3560-X
A. The Catalyst 3750-X and 3560-X Series support 802.1ae encryption at line
rate. This hardware encryption is done between the switch port and the client's
network interface card (NIC). Some Intel NIC and LAN on Motherboard (LoM)
components already support 802.1ae. Some PC and laptop manufacturers may have
not implemented the encryption feature, although the capability is already
Q. The NICs in my installed client base do not have encryption capability. Will
I be able to deploy Cisco Catalyst 3750-X and 3560-X Series Switches in my
A. Cisco will offer a software-based application that can provide encryption
for legacy PCs and laptops. In these cases, the software client will handle
encryption. This client will also provide for key negotiation as described by
MACsec Key Agreement (MKA).
Q. Do the Cisco Catalyst 3750-X and 3560-X Series Switches have encryption on
all ports, including the uplinks?
A. No. Hardware encryption is provided only on the user ports (downlinks).
Q. What is the competition doing in terms of hardware encryption?
A. IEEE 802.1ae is a standard; hence any competitor has the same opportunity to
build products that support encryption. The strength of the Cisco Catalyst
3750-X and 3560-X Series Switches is that encryption is just one piece of the
whole Cisco TrustSec solution, and competitors can offer only point products or
