Release L.10.08 Enhancements
Release L.10.08 includes the following enhancements:
■ Increased the maximum number of 802.1X users per port to 8.
■ 802.1X Controlled Directions enhancement. With this change, Administrators can use “Wake-
on-LAN” with computers that are connected to ports configured for 802.1X authentication.
Configuring 802.1X Controlled Directions
After you enable 802.1X authentication on specified ports, you can use the aaa port-access controlled-
directions command to configure how a port transmits traffic before it successfully authenticates a
client and enters the authenticated state.
As documented in the IEEE 802.1X standard, an 802.1X-aware port that is unauthenticated can
control traffic in either of the following ways:
■ In both ingress and egress directions by disabling both the reception of incoming frames and
transmission of outgoing frames
■ Only in the ingress direction by disabling only the reception of incoming frames.
Prerequisite. As documented in the IEEE 802.1X standard, the disabling of incoming traffic and
transmission of outgoing traffic on an 802.1X-aware egress port in an unauthenticated state (using
the aaa port-access controlled-directions in command) is supported only if:
■ The port is configured as an edge port in the network using the spanning-tree edge-port
command.
■ The 802.1s Multiple Spanning Tree Protocol (MSTP) or 802.1w Rapid Spanning Tree Protocol
(RSTP) is enabled on the switch. MSTP and RSTP improve resource utilization while
maintaining a loop-free network.
For information on how to configure the prerequisites for using the aaa port-access controlled-
directions in command, see Chapter 4, “Multiple Instance Spanning-Tree Operation” in the Advanced
Traffic Management Guide.
Syntax: aaa port-access <port-list > controlled-directions <both | in>
both (default): Incoming and outgoing traffic is blocked on
an 802.1X-aware port before authentication occurs.
in: Incoming traffic is blocked on an 802.1X-aware port
before authentication occurs. Outgoing traffic with
unknown destination addresses is flooded on
unauthenticated 802.1X-aware ports.
