This might cause informational ARP address reassignment messages to appear on other switches in the fabric. This is normal behavior, because the association between the IP addresses and MAC addresses has changed. For 50-km extended links, you have a choice of configuring a port as an LD port or an L1 port. LD ports maintain full link speeds of 103 Mbit/sec. L1 ports have link speeds of 99 Mbit/sec; you can configure all four ports of a quad as L1 ports, but you can configure only one port in a quad as an LD port. During fabric configuration, the countdown message that used to appear on the console is removed starting with Fabric OS v2.6.2, v3.1.2, and v4.2.x. The fabric reconfiguration message is now captured in the error log. For details, refer to the diagnostic messages in the HP StorageWorks Diagnostic and System Error Messages 4.2.x Reference Guide. 14 SAN Director 2/128 Fabric OS 4.2.x Release Notes
