It prohibits unknown/unauthorized clients from connecting to an Ethernet network through publicly accessible ports. The authentication server component of the system authenticates each client device or host connected to an authentication-enabled network port. Until the client is authenticated, 802.1x allows only the authentication protocol traffic (EAPOL) on the connected port. Once authentication is successful, the port is open for all network traffic. • The FIP VLAN Discovery protocol is supported with the following caveat: the FIP VLAN DISCOVERY request must be received with either a priority-only VLAN tag (VLAN ID = 0), or a VLAN tag with VLAN ID = FCoE VLAN. FIP VLAN DISCOVERY request received with a valid VLAN ID in the tag that is not equal to the FCoE VLAN is dropped. The expected behavior is that the converged network adapter (CNA) will send a priority-tagged FIP VLAN DISCOVERY request. 6

Adaptive Networking
—
New features were first introduced with Fabric OS 6.0, including FC QoS,
which allows users to establish flow-based prioritization of traffic over a SAN. Fabric OS 6.3 ex-
tends QoS over FCR configurations, allowing support of QoS for traffic flows originating in an
edge fabric, passing through the FC backbone fabric, and then continuing to a destination edge
fabric. This feature requires configuration of both LSAN zones and QoS zones, and requires that
the Adaptive Networking license be installed on switches in both the edge and backbone fabrics.
Adaptive Networking enhancements
If one or more applications running on the data center fabric are slowing down, the administrator
can enable the new Bottleneck Detection feature on all suspected edge switches to which F_Ports are
attached. Using this feature, the administrator can determine whether there are any slow-draining
devices causing network congestion. When this feature is enabled and a switch detects a condition
where the offered load exceeds the rate at which the destination device can accept frames, a RASLog
message is generated and the administrator can view historic statistics logs for the port to investigate
the problem. This new capability is considered part of the Adaptive Networking feature set, but does
not require a license. This feature is available on all 4-Gb and 8-Gb ports.

239 DID mode. Previously, connecting to such fabrics could only be done through FCR.
•
Fabric OS-based platforms operating in either interopmode 2 or 3 can now participate in M-EOS
fabrics using nondefault DID Base Offset settings.
