to enable those devices to login through that F_port. This policy is also supported for NPIV connections on F_ports. • 16 bit routing enhances interoperability of Access Gateway with Cisco fabrics. This capability only applies to 8Gb platforms. Traffic Isolation zones over FCR This enhancement enables traffic isolation across EX ports and VEX ports. This benefits applications like Tape Pipelining and Fast Write that traverse VE ports where customers want to control the exact path and ports that are used. Port Mirroring Fabric OS 6.1.x adds support for Port Mirroring to 8Gb ports. The Port Mirroring feature mirrors traffic in both directions between a source and destination ID pair to a single mirror port. The user may connect a FC analyzer to this mirror port to capture all the mirrored traffic and perform troubleshooting or other analysis. Buffer credit recovery Fabric OS 6.1.x implements credit recovery protocol as described in FC-FS standards. This feature is supported only on E-ports and allows switches to automatically recover buffer credits that were accidentally "lost" over time. Buffer credit recovery prevents link performance degradation that may otherwise occur due to loss of credits over time. FCIP performance enhancements Fabric OS 6.1.x increases committed rate tunnel performance (utilization) when compressibility exceeds 2:1. Previous firmware releases capped FC data rates to 2 times the committed rate of the FCIP tunnel. As a result, as compression ratio increases beyond 2:1, FC throughput remains constant at 2 times the committed rate and the link utilization decreases. Fabric OS 6.1.x now monitors compressibility, adjusts to more compressible data, and works to fill the FCIP tunnel to the committed rate. Port Fencing Fabric OS 6.1.x includes new Port Fencing capabilities that can automatically isolate a port that is behaving outside the bounds of a normal, expected operation. This enhances overall stability of the fabric in the event of an isolated event that could otherwise cause a major disruption if left unattended. The Port Fencing capability is included as part of the optionally licensed Fabric Watch feature. LDAP FOS 6.1 includes enhancements to LDAP allowing Active Directory server roles to be mapped to the various switch roles. Parameter added for slotshow command Optional -m parameter for slotshow command to display Model Names for each blade installed in a DC SAN Backbone Director or 4/256 SAN Director chassis. Scripting Many automatic page breaks in CLI output for commands have been removed to better facilitate scripting. Notification of duplicate WWN entry RASLOG entry when a switch detects a duplicate WWN has logged in. HP StorageWorks Fabric OS 6.1.0a release notes 7
