Cluster I/O Protocols (CIP) Configuration and Management Manual (H06.16+, J06.05+)

Trace Filename
Is the name of the current trace file.
Trace Status
ON when the process is being traced using SCF.
Trace Filename
Is the name of the current trace file.
ARPTIMER-REFRESHED
Always ON in the CIP environment. This attribute causes TCP to restart the ARP timer every
time the ARP table entry is referenced when transmitting an IP packet.
Some of the other attributes are no longer viewable with the CIP info process command but can
be checked by issuing a sysctl command. Some attributes are not applicable in CIP and some are
still applicable and available through the INFO PROCESS CIPSAM command.
TCP Send Space
tacl> CLIMCMD clim-name sysctl net.ipv4.tcp_wmem. Is the space reserved for
send operations for the TCP protocol.
TCP Receive Space
tacl> CLIMCMD clim-name sysctl net.ipv4.tcp_rmem. Is the space reserved for
receive operations for the TCP protocol.
UDP Send Space
tacl> CLIMCMD clim-name sysctl net.core.wmem_max or tacl> CLIMCMD
clim-name sysctl net.core.wmem_default. Is the space reserved for send operations
for the UDP protocol.
UDP Receive Space
tacl> CLIMCMD clim-name sysctl net.ipv4.tcp_rmem or tacl> CLIMCMD
clim-name sysctl net.core.rmem_default. Is the space reserved for send operations
for the UDP protocol.
Delay Ack
Is a switch indicating if TCP is delaying acknowledgments. This attribute no longer applies in
the CIP environment.
Delay Ack Time
Is the amount of time in 10 ms intervals that the acknowledgments are delayed. This attribute
no longer applies in the CIP environment.
Keep Alive Idle
tacl> CLIMCMD clim-name sysctl net.ipv4.tcp_keepalive_time. Is the amount
of time in seconds before TCP issues a keep-alive packet on sockets that have enabled this
option. See also “TCP/IP Attributes in CIP” (page 193).
Keep Alive Retry Cnt
tacl> CLIMCMD clim-name sysctl net.ipv4.tcp_keepalive_probes. Is the number
of times a keep-alive packet is sent without receiving an acknowledgment after which the TCP
connection is dropped.
Keep Alive Interval
tacl> CLIMCMD clim-name sysctl net.ipv4.tcp_keepalive_intvl. Is the time
interval in seconds between retransmissions of unacknowledged keep-alive packets. See also
“TCP/IP Attributes in CIP” (page 193).
QIO Limit
scf> STATUS MON $ZZCIP.ZCMnn, detail. Is a percentage between 0 and 100,
representing the amount of queued I/O or shared memory allowed to this process.
