tcp maximum-bandwidth-kbps Chapter 23 T Commands Send documentation comments to [email protected] tcp maximum-bandwidth-kbps To manage the TCP window size in Kbps, use the tcp maximum-bandwidth-kbps command. Use the no form of this command to disable this feature or revert to its factory defaults. tcp max-bandwidth-kbps bandwidth min-available-bandwidth-kbps threshold {round-trip-time-ms milliseconds | round-trip-time-us microseconds} no tcp max-bandwidth-kbps bandwidth min-available-bandwidth-kbps threshold {round-trip-time-ms milliseconds | round-trip-time-us microseconds} Syntax Description bandwidth Specifies the Kbps bandwidth. The range is 1000 to 1000000. min-available-bandwidth-kbps Configures the minimum slow start threshold. threshold Specifies the Kbps threshold. The range is 1000 to 1000000. round-trip-time-ms milliseconds Configures the estimated round trip time across the IP network to reach the FCIP peer end point in milliseconds. The range is 0 to 300. round-trip-time-us microeconds Configures the estimated round trip time across the IP network to reach the FCIP peer end point in microseconds. The range is 0 to 300000. 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) Modification This command was introduced. 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)# 23-28 Cisco MDS 9000 Family Command Reference OL-18089-01, Cisco MDS NX-OS Release 4.x
