Port-level Parameters
A-8 SN0054621-00 E
S
KeepAliveTO 0–65535
seconds
KATO This parameter indicates the time interval (in
seconds) between connection keep-alive pings.
When a connection is idle for the connection
keep-alive timeout interval, the HBA sends an
NOP ping to the other device (target) that is part
of the connection. When the (target) device
responds to the ping, the connection remains
open. If the (target) device fails to respond, the
HBA closes the connection and informs the
driver that the connection has gone down. The
maximum keep-alive time is 18 hours.
Large_Frames
a
on, off LRGFRM (Not for QLA4010s) Defines the maximum
Ethernet frame length. On sets for Jumbo (9kB
max) frames. Off sets frame length to 1.5 KB.
Determines when to fragment IP datagrams;
larger frames are discarded.
LDROUTER_AUTO on, off LDRA Local default router. Gets router address auto-
matically.
LOC_LINK_AUTO on, off LOCLA Local link auto.
MaxBurstLen 0–32767
units
a
MBL Tells max length for data sequences the HBA
uses when negotiating with a target device dur-
ing login. Tells how many 512 byte units the
HBA can send/receive. 0 means unlimited data
units.
MaxOutstandingR2T 1–
65535
MOR2T Tells maximum number of outstanding R2Ts the
HBA uses when negotiating during login. Tells
how many R2Ts can be outstanding on a SCSI
task.
MaxRxDataSegmentLen
a
0–
65535
n/a Tells maximum data segment size (in 512-byte
units) that the HBA can receive in one PDU.
Port
a
0–
65535
n/a Gives the port number the HBA (as target) lis-
tens to for iSCSI connections. Ignored when the
HBA is an initiator only. Default port = 3260.
ROUTABLE_AUTO on, off RAUTO When on, the firmware will auto-configure
routable addresses from the default router (if
one is available)
