  • Before the installation of the Upgrade License, ports beyond the basic four FC and two GbE are shown as Disabled with the switchShow command.
  • On the base 7800, the two SFP ports (ge0 and ge1) can be configured for use with either copper or optical cables.
  • FC frame compression is not the same as IP compression and is disabled by default. It can be enabled using the portCfg command. For more information see the Brocade Fabric OS Administration Guide.
  • FCIP tunnel bandwidth has a minimum rate of 1544 Kbps (T1 rate). Configuration requests of lower rates will be rejected.
  • FCIP Trunking is available which will "virtualize" two or more TCP connections (circuits) as part of a single FCIP tunnel. Up to four circuits can be configured for a single FCIP tunnel. See the Brocade Fabric OS Administration Guide for details on explicitly configuring circuits.
  • Multiple FCIP tunnels can share the same GbE port. At the same time, VE_ and VEx_Ports are not associated with a single physical GbE port.
