ALTER SUBNET Command
ALTER SUBNET Command
The ALTER SUBNET command is used to change the attribute values of a SUBNET.
Command Syntax
OUT file-spec
causes any SCF output generated for this command to be directed to the specified
file.
SUBNET subnet-spec
names the point of connection between the NonStop TCP/IP process and an I/O
device. The fully-qualified subnet-spec has the form:
If you specify the SCF object type (SUBNET) or any portion of the object name
(subnet-spec) in a prior ASSUME command, you can omit it in this command.
For information about the ASSUME command, see the SCF Reference Manual for
G-Series RVUs or the SCF Reference Manual for H-Series RVUs.
IPADDRESS ip_address
is the 32-bit integer that identifies the subnet. This is the IP address assigned to
the SUBNET.
SUBNETMASK subnet-mask
is a 32-bit integer that specifies the subnet mask to be used with this subnet.
A subnet mask identifies which portion 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 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 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). The mask-val is specified in
hexadecimal notation. If it is not specified, ask-val defaults to the default network
mask of the specified IP address. Non-contiguous mask values are not supported.
