AB291A Fabric Clustering System Support Guide (12-port Switch), April 2004

HP 12-Port 4X Fabric Copper Switch Commands
IP Commands
Appendix B
229
Usage Guidelines:
The maximum transmission unit is described in terms of payload size. TCP uses the MTU to determine the
maximum payload allowed for every transmission. Too great a value can overwhelm routers and result in
data retransmission. Too small a value results in degraded performance because there are more headers and
acknowledgements required to transmit the same amount of data.
Examples:
HP-IB(config)# default ip ip-over-ib-mtu
Defaults:
The default ip-over-ib-mtu is 2048.
NOTE This command should not be used as change in MTU is not supported.
