11. At the Window Scaling prompt, enable or disable this setting. Window
scaling must be enabled when using a Window Scaling Factor (see
next step) greater than zero.
12. At the Window Scaling Factor prompt, enter a value from 0 through
9 as scaling factor, based on the TCP Window Size for the WAN
specified in Step 10 (see “TCP Window Settings” on page 5-14).
13. (Optional) Changing the TCP port number at the TCP Port No. prompt
should not be required. If you change this value, do not use a well-known
TCP port number. The TCP port numbers on both the local and remote
routers should be the same.
14. At the GE Port Speed prompt, select a GE port speed that matches that
of the Ethernet switch port to which it is connected. QLogic recommends
that you use a gigabit managed switch that is capable of automatically
negotiating the port speed. If the Ethernet switch port speed is not capable
of auto negotiation, set both the router and Ethernet switch to the same port
speed.
15. At the Bandwidth, Mbit/sec prompt, enter a value from 1 through
1000 for the route bandwidth. To determine this value, see “Bandwidth
Limiting” on page 5-14.
16. At the VLAN prompt, enable or disable VLAN support as needed. Enable
VLAN only if it is supported by the Ethernet switch.
17. At the FCIP SW Compression prompt, enable or disable data
compression (see “Data Compression” on page 5-14 to determine if
compression should be enabled).
E_Port Extension
The FCIP configuration used to interconnect (merge) two SANs separated by
distance 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 same
manufacturer, and support ISLs using the E_Port protocol.
Figure 5-1 shows an example of a single FCIP route (single ISL).
