Network Edge Access Topology (NEAT) enhancement: In the default state, when a supplicant switch is
connected to an authenticator switch that has BPDU guard enabled, the authenticator port could be error-
disabled if it receives a Spanning Tree Protocol (STP) bridge protocol data unit (BPDU) packets before the
supplicant switch has authenticated. Beginning with Cisco IOS Release 15.0(1)SE, you can control traffic
exiting the supplicant port during the authentication period by entering the dot1x supplicant controlled
transient global configuration command. It temporarily blocks the supplicant port during authentication to
ensure that the authenticator port does not shut down before authentication completes. Note that this
command is also available in Cisco IOS Software Release 12.2(55)SE3 (and later rebuilds).
●
Support for Cisco TrustSec Security Group Tag (SGT) Exchange Protocol (SXP) version 2 and
Enhancements: Tagging packets with SGTs requires hardware support. You might have devices in your
network that, while capable of participating in Cisco TrustSec authentication, lack the hardware capability
to tag packets with SGTs. By using the SGT Exchange Protocol (SXP), these devices can pass IP-address-
to-SGT mappings to a Cisco TrustSec peer device that has Cisco TrustSec-capable hardware thus
enabling role-based security solutions across the network. SXPv2 provides the enhancements by
supporting SXP version negotiation. In addition, Syslog message generation and SXP SNMP MIBs are
supported. The SXP Syslog feature allows the switch to send SXP logging messages, like SXP state
changes, connection status updates, error messages and binding updates to various destinations, such as
the syslog server. SXP version negotiation allows backward compatibility with the peers running SXP
version 1.
