ADD SUBNET Command for TCP6MAN
for the monitors, it is assumed. The naming convention for SUBNETs is seven
characters. The first character must be a letter. HP recommends making the first
two characters SN.
TYPE ETHERNET
specifies the type of SUBNET to be added. The only valid type is Ethernet. This
parameter is required. There is no default.
DEVICENAME lif-name
is the name of the device to be opened to connect to the network. This
corresponds to the ServerNet LAN systems access (SLSA) logical interface (LIF).
The LIF provides access to the Ethernet LAN. For information on how to choose a
SLSA device name, see step 3 on page 1-2. When adding a SUBNET, the
DEVICENAME for the SLSA SUBNET does not begin with a dollar sign ($)
character. There is no default.
IPADDRESS ip-addr
is the 32-bit IPv4 address associated with this SUBNET interface. This parameter
is required. There is no default.
FAMILY INET
specifies that the socket-family type of the SUBNET as AF_INET (IPv4). The
default value for the FAMILY attribute is INET.
IRDP {ON | OFF}
enables (ON) or disables (OFF) the ICMP Router Discovery Protocol on the
SUBNET interface. IRDP is a mechanism for locating default routers and is
specified in RFC 1256. IRDP also must be enabled on any local LAN routers. If
redundant routers are configured with route hold-down times and advertisement
intervals of approximately 30 seconds, IRDP can be used to provide a “black hole,"
or dead gateway, detection mechanism. The NonStop TCP/IPv6 subsystem
implements IRDP using IP broadcasts rather than IP multicasts. The default is
OFF.
SUBNETMASK mask-val
specifies the part of the IPv4 address that must be masked to borrow bits from the
host portion of the address and use them to designate a SUBNET. Subnet masks
enable you to generate additional subnets from CLASS A, CLASS B and CLASS C
networks. This mask-val is specified as dotted-decimal or hexadecimal notation.
If it is not specified, it defaults to the corresponding network mask of the specified
IP address. A non-contiguous mask value is not supported. Because a non-
contiguous mask value is not supported, netmask values such as 0.255.255.0,
255.0.255.0, 0.0.255.0 are considered invalid.
