tcp maximum-bandwidth-mbps
To manage the TCP window size in Mbps, use the tcp maximum-bandwidth-mbps command. Use the
no form of this command to disable this feature or revert to its factory defaults.
Syntax Description bandwidth
min-available-bandwidth-mbps
threshold
round-trip-time-ms milliseconds
round-trip-time-us microeconds
Defaults Enabled.
The FCIP defaults are max-bandwidth = 1G, min-available-bandwidth = 500 Mbps, and
round-trip-time =1 ms.
The iSCSI defaults are max-bandwidth = 1G, min-available-bandwidth = 70 Kbps, and
round-trip-time =1 ms.
Command Modes
FCIP profile configuration submode.
Command History Release
1.1(1)
Usage Guidelines The maximum-bandwidth option and the round-trip-time option together determine the window size.
The minimum-available-bandwidth option and the round-trip-time option together determine the
threshold below which TCP aggressively increases its size. After it reaches the threshold the software
uses standard TCP rules to reach the maximum available bandwidth.
Examples The following example configures a FCIP profile:
switch# config terminal
switch(config)# fcip profile 5
switch(config-profile)#
