Use portCfg fciptunnel with the -bstr parameter to display parameters related to the Byte Streaming
feature. Byte streaming allows the Brocade switch to communicate with third party WAN
optimization hardware. Refer to portCfg for more information on this feature. The following
parameters are displayed:
Head index
Tail index
Current count
Pending Frames High
Segment Count High
Data Mover Restarts
Frame Too Large Count
Max Reference Count
Max Frame Size
Max Segments
Reached Max Pending
FCIP Smoothed RTT
FCIP RTT Variance
Operands This command supports the following operands:
