Firmware Summary Table B-4 E/OS versus E/OSn and E/OSi - System-Related Differences (Continued) Feature Misaligned word generation Flexible partition (FlexPar) feature support Maintenance port access E/OS 7.0 E/OSn 6.0 E/OSi 4.6 Misaligned words not generated. Misaligned word is generated when the port state machine (PSM) transitions from inactive to active state or from active to inactive state. This anomaly has no effect on Fibre Channel device behavior. Misaligned words not generated. Flexpar feature not supported. Up to four FlexPars supported Flexpar feature not supported. for each Intrepid 10000 Director chassis. For directors, one 9-pin, RS-232 serial port shared between two CTP cards. Port-attached device communicates only with the active card. For fabric switches, one 9-pin, RS-232 serial port per switch. Each CTP card has an independent 9-pin, RS-232 serial port that provides access to engineering-level interfaces. Maintenance mode and command line interface (CLI) available through the active CTP card port. One 9-pin, RS-232 serial port per SAN router. Fibre Channel Protocol-Related Differences Table B-5 summarizes Fibre Channel protocol-related differences between the E/OS 7.0, E/OSn 6.0, and E/OSi 4.6 firmware versions. Table B-5 E/OS versus E/OSn and E/OSi - Fibre Channel Protocol-Related Differences Feature E/OS 7.0 E/OSn 6.0 E/OSi 4.6 Node port (N_Port) ID assignment N_Port ID assigned based on port number plus offset of four. Device attached to port nn obtains N_Port ID of dd(nn+4)xx, where dd is the switch domain ID and xx is hexadecimal 13. N_Port ID assigned based on port number. Device attached to Port nn obtains N_Port ID of ddnnxx, where dd is the switch domain ID and xx is hexadecimal 13. N_Port ID assigned based on port number. Device attached to Port nn obtains N_Port ID of ddnnxx, where dd is the switch domain ID (always 01) and xx is hexadecimal 13. Exchange switch support (ESS) sequence transmission ESS not transmitted until fabric shortest path first (FSPF) algorithm obtains best hop to target domain. ESS transmitted at the moment adjacency to the target domain is detected (link at FSPF FULL state). Therefore, ESS always transmitted sooner for an Intrepid 10000 Director. ESS transmitted only in response to an ESS received from another fabric element. Firmware Summary B-3
