tcp maximum-bandwidth-mbps Chapter 23 T Commands Send documentation comments to [email protected] 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. tcp max-bandwidth-mbps bandwidth min-available-bandwidth-mbps threshold {round-trip-time-ms milliseconds | round-trip-time-us microseconds} no tcp max-bandwidth-mbps bandwidth min-available-bandwidth-mbps threshold {round-trip-time-ms milliseconds | round-trip-time-us microseconds} Syntax Description bandwidth min-available-bandwidth-mbps threshold round-trip-time-ms milliseconds round-trip-time-us microeconds Specifies the Mbps bandwidth. The range is 1 to 1000. Configures the minimum slow start threshold. Specifies the Mbps threshold. The range is 1 to 1000. 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. 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)# 23-30 Cisco MDS 9000 Family Command Reference OL-16217-01, Cisco MDS SAN-OS Release 3.x
