5–Fibre Channel over IPConfiguring FCIPE_Port Extension11. At the Window Scaling prompt, enable or disable this setting. Windowscaling must be enabled when using a Window Scaling Factor (seenext step) greater than zero.12. At the Window Scaling Factor prompt, enter a value from 0 through9 as scaling factor, based on the TCP Window Size for the WANspecified in Step 10 (see “TCP Window Settings” on page 5-14).13. (Optional) Changing the TCP port number at the TCP Port No. promptshould not be required. If you change this value, do not use a well-knownTCP port number. The TCP port numbers on both the local and remoterouters should be the same.14. At the GE Port Speed prompt, select a GE port speed that matches thatof the Ethernet switch port to which it is connected. QLogic recommendsthat you use a gigabit managed switch that is capable of automaticallynegotiating the port speed. If the Ethernet switch port speed is not capableof auto negotiation, set both the router and Ethernet switch to the same portspeed.15. At the Bandwidth, Mbit/sec prompt, enter a value from 1 through1000 for the route bandwidth. To determine this value, see “BandwidthLimiting” on page 5-14.16. At the VLAN prompt, enable or disable VLAN support as needed. EnableVLAN only if it is supported by the Ethernet switch.17. At the FCIP SW Compression prompt, enable or disable datacompression (see “Data Compression” on page 5-14 to determine ifcompression should be enabled).The FCIP configuration used to interconnect (merge) two SANs separated bydistance is referred to as an E_Port extension. The SANs to be interconnected(merged) must be made up of similar Fibre Channel switches, from the samemanufacturer, and support ISLs using the E_Port protocol.Figure 5-1 shows an example of a single FCIP route (single ISL).ISR651101-00 G 5-5
