We are implementing a dedicated VLAN for gigabit-ethernet traffic and jumbo
frames, primarily for backup/recovery TSM traffic. Do the following settings
make sense for TSM/AIX servers in a large (2TB per backup window)
environment? Any recommendations for network switch settings (i.e. keeping
MTU size high, etc.)? Other considerations?

Thanks and Regards, John

AIX Gigabit Ethernet Settings:

Transmit and Receive jumbo frames YES
Software transmit queue size 1024
Maximum IP Packet Size for this device 9000
AIX no options
rfc1323=1
sb_max=1048578
thewall=524340

TSM Settings:
TCPWindowsize 65536
TCPBufsize 16384
