INFO Command
ZSPI-VAL-FALSE
indicates that the QIO segment is not to be saved when the TCP/IP
process abends.
ZALLNETSARELOCAL
is a Boolean variable; ON causes TCP to use the interface MTU as a base for
determining the TCP Maximum Segment Size (MSS) for each non-local TCP
connection. A non-local TCP connection is one that goes to another network
(not just another subnetwork). OFF causes TCP to conform to RFC-specified
behavior and use 512 bytes as the default MSS for non-local segments. For
example, for Ethernet, when ALLNETSARELOCAL is ON, the non-local MSS
will be 1460; setting ALLNETSARELOCAL to ON can improve performance.
The default is ON.
ZTCP-COMPAT-42
is the flag used to set the TCP/IP process compatible with BSD 4.2 versions as
follows: if the flag is ON, then the original ACK minus 1 is sent in the keepalive
packet; if the flag is OFF, the original ACK is sent in the keepalive packet. The
default value of this flag is ON.
ZTCI-MAP-INFO-SUBNET
is an extensible structured token that lists the configurable attributes for a subnet. It
has the token number ZTCI-TNM-INFO-SUBNET and the DDL definition
ZTCI-DDLINFOSUBNET. This extensible structured token always appears in the
response when the specified object is ZCOM-OBJ-SUBNET. Duplicate
occurrences of the fields are not allowed.
The fields in the ZTCI-MAP-INFO-SUBNET extensible structured token are:
ZIP-ADDR
is a 32-bit integer that specifies the address of the subnet or the loopback
address. Either value is specified as an IP address. The conventional loopback
address (which is used for testing purposes) is 127.1.
ZSUBNET-MASK
is a 32-bit integer that specifies the subnet mask to be used with this subnet. A
subnet mask identifies which part of the IP local address represents the subnet
number and which part represents the host ID. If bits in the subnet mask are
set to 1, the corresponding bits in the IP address are to be part of the network
(and subnet) address. If bits in the subnet mask are set to 0, the corresponding
bits in the IP address are to be part of the host ID (that is, that portion of the
local address masked with 1s identifies the subnet, and the remainder of the
local address uniquely identifies a host connected to the subnet). For further
details on subnet addressing, subnet masking, and the various classes of IP
addresses, see theTCP/IP Configuration and Management Manual.
