Note that FCIP tunnel activation is the same as an FC EISL becoming active (such as ELP, ESC, and EFP). The following traces were captured after configuration on both MDS 9000 Family switches, and the last no shutdown was entered on switch MDS1. All settings are default (for example, SACK is disabled, and the TCP window is set to 64K). Figure 20-3 First Capture of TCP Connection TCP connection Figure 20-4 shows more of the trace, with frame 13 being the first FCIP frame. This frame carries the FC Standard ELP. 20-18 Cisco MDS 9000 Family Troubleshooting Guide, Release 3.x OL-9285-05
