•Chapter 2

-Under “7800 switch hardware overview,” added the following notes:

•Copper ports do not support auto-sense functions.

•With copper media, auto-negotiation must be enabled on the other end of the port

-Under “VE_Ports and FCIP tunnels on the 7800 switch” and “VE_Ports and FCIP tunnels

on the FX8-24 blade” added the following note:

-VE_Ports or VEX_Ports cannot connect to the same domain at the same time as Fibre

Channel E_Ports or EX_Ports.

-Under “VE_Ports and FCIP tunnels on the 7800 switch” and “VE_Ports and FCIP tunnels

on the FX8-24 blade” a note was added concerning VE_Ports.

-Under “FCIP tunnel restrictions for FCP and FICON acceleration features,” added

restrictions about FCIP tunnels not supporting DPS and that both ends of the FICON

emulating tunnel must run Fabric OS v7.0 or later if one end of tunnel runs v7.0 or later.

-Under “FCIP circuit failover capabilities, added “Failover in TI zones” section.

-Under “Limitations using IPsec over FCIP tunnels,” added limitation that IPsec is not

supported on VE group 12-21 on FX8-24 blades and that to enable IPsec with Fabric OS

-Added timeout value information under the “keep-alive timeout” option.
