ALTER MON Command for TCP6MAN
FAMILY { INET | INET6 | DUAL }
specifies the network mode of the TCP6MON. You can specify these modes:
TCP-MAX-REXMIT-TIMEOUT
is the maximum time value in milliseconds allowed for a TCP retransmission
timeout. The default is 64000 milliseconds. The range is 500 to 1200000 (.5
seconds to 20 minutes).
TCP-MAX-REXMIT-COUNT
is the maximum number of continuous retransmissions allowed before a TCP
connection is dropped. The default is 12. The range is 1 to 12.
TCP-TOTAL-REXMIT-DURATION
is the total time a TCP connection can be in the retransmission state without
receiving an acknowledgement from the other endpoint before the TCP connection
is dropped. The default is 720000 milliseconds. The range is 500 to 14400000 (.5
seconds to 4 hours). Note that a connection can be dropped sooner if the TCP-
MAX-REXMIT-COUNT multiplied by the TCP-MAX-REXMIT-TIMEOUT is a value
less than the TCP-TOTAL-REXMIT-DURATION.
PORT-SHARE-ENABLE { ON | OFF }
allows applications running in different processors to share a port but have different
IP addresses when set to ON. When set to OFF, applications trying to share a port
while having different IP addresses fail to bind. The default setting is OFF.
ARPTIMER-REFRESHED { ON | OFF }
causes TCP to restart the ARP timer every time the ARP table entry is referenced
when transmitting an IP packet. The default value is ON. If this option is enabled,
stale ARP table entries might take longer time to be flushed.
ICMP-FILTER-PKTS int
specifies a 32-bit hexadecimal integer value. This value is used to control the
inflow of the ICMP packets into the system. When the specified bits (see table
below) are set (1), the corresponding ICMP packets are dropped or rejected. When
the specified bits are reset (0), the corresponding ICMP packets are allowed or
accepted.
INET TCP6MON is operated in IPv4 only mode.
INET6 TCP6MON is operated in IPv6 only mode.
DUAL TCP6MON is operated in both IPv4 mode andPv6 mode.
Note. The ARPTIMER-REFRESHED and ICMP-FILTER-PKTS attributes are supported
only on systems running G06.29 and later G-series RVUs.
