• The CLI syntax for the 1606 Extension SAN Switch/DC SAN Director Multiprotocol Extension Blade varies from the 7500/FR4-18i. See the Brocade Fabric OS Command Reference document for FOS 6.3 for details. • Both ends of a tunnel must be identically configured for the Compression, FastWrite, and Tape Pipeline options. If a mismatch exists, the tunnel will not be established and the TCP virtual connections will be removed. • Under traffic isolation (TI) zone configurations with failover enabled, non-TI zone traffic will use the dedicated path if no other E or VE paths through the fabric exist, or if the nondedicated paths are not the shortest paths. (A higher bandwidth tunnel with multiple circuits will become the shortest path compared to a single tunnel.) • A VE/VEX tunnel and E/EX FC port cannot connect to the same domain at the same time. • The recommended Keep Alive Timeout must be the same on the tunnel and circuits on the switches on both sides of a link. • The 1606 Extension SAN Switch and DC SAN Director Multiprotocol Extension Blade cannot receive a ping from an external device (for example, a Windows PC). • Latency measurements supported on FCIP tunnels (tested limit under FOS 6.3.0): • 1 GbE with 200 ms round-trip time and 1% loss • 10 GbE with 50 ms round-trip time and 0.1% loss • The 1606 Extension SAN Switch supports optical and copper media types on GE0 and GE1 interfaces. Copper media is the default on GE0/GE1 ports and does not support autosense functions. • Inserting a 4 Gb SFP in GE ports of an HP StorageWorks 1606 Extension SAN Switch or DC SAN Director Multiprotocol Extension Blade, can occasionally return one of the following messages: • No_Light or Unknown for GE ports in switchshow output. Remove and reinsert the optic cable to correct this indication. • Can't read serial data in sfpshow output. Reissue the sfpshow command to resolve this issue. FCoE/CEE (2408 FCoE Converged Network Switch and DC SAN Director Switch 10/24 FCoE Blade) • The 2408 FCoE Converged Network Switch balances the FCoE bandwidth across all six port groups (each port group contains four ports). To get optimum performance for FCoE traffic HP recommends that the user distribute server CNA connections across these six port groups. • Hot-plugging a CP with a firmware level earlier than FOS 6.3.0 into a DC SAN Backbone Director or DC04 SAN Director with an active DC SAN Director Switch 10/24 FCoE Blade will result in the new standby CP not coming up. • HP recommends that Converged Mode be enabled on all interfaces connected to CNAs. • When operating in Converged Mode, tagged traffic on the native VLAN of the switch interface is processed normally. The host should be configured not to send VLAN tagged traffic on the switch's native VLAN. • The CNA may lose connectivity to the 2408 FCoE Converged Network Switch/DC SAN Director Switch 10/24 FCoE Blade if the CNA interface is toggled repeatedly over time. This issue is related to the CNA; rebooting the CNA restores connectivity. • Although the 2408 FCoE Converged Network Switch/DC SAN Director Switch 10/24 FCoE Blade support the configuration of multiple CEE maps, HP recommends that you use only one CEE map on all interfaces connected to CNAs. Additionally, CEE maps are not recommended for use with non-FCoE traffic. QoS commands are for interfaces carrying non-FCoE traffic. 26
