Full Discussion: Network tuning parameters on AIX
Operating Systems AIX Network tuning parameters on AIX Post 302892023 by ibmtech on Monday 10th of March 2014 11:04:13 AM

chdev command is only for that adapter's interface (enX).
Whereas no will set the network tuning parameter across the board.

Example: If you have two interfaces (one primary 'entX', one for backups 'entY'), if you use no command the settings are reflected on both adapters interfaces (entX & entY). But if you use chdev -l entX -a XXX this setting is only reflected on the interface (enX) of that particular adapter (entX), and not on other adapter's interface.

Hope this make sense.

     trm -- Tekram TRM-S1040 ASIC based PCI SCSI host adapter driver

SYNOPSIS

     trm* at pci? dev ? function ?
     scsibus* at trm?

DESCRIPTION

     The trm driver supports PCI SCSI host adapters based on the Tekram TRM-S1040 SCSI ASIC.

HARDWARE

     Supported SCSI controllers include:

	   Tekram DC-315 PCI Ultra SCSI adapter without flash BIOS and internal SCSI connector

	   Tekram DC-315U PCI Ultra SCSI adapter without flash BIOS

	   Tekram DC-395U PCI Ultra SCSI adapter with flash BIOS

	   Tekram DC-395UW PCI Ultra-Wide SCSI adapter with flash BIOS

	   Tekram DC-395F PCI Ultra-Wide SCSI adapter with flash BIOS and 68-pin external SCSI connector

     For Tekram DC-390 PCI SCSI host adapter, use pcscp(4) driver.
