ADD SUBNET Command for TCPMAN
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.
DEVICENAME lif-name
is the name of the device to be opened to connect to the network. This
corresponds to the SLSA logical interface (LIF). The LIF provides access to the
Ethernet LAN. For information on how to choose a SLSA device name, see step e
on page 1-4. When adding a subnet, the DEVICENAME for the SLSA subnet does
not begin with a dollar ($) character.
IPADDRESS ip-addr
is the Internet address associated with this subnet interface. This parameter is
required.
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 Parallel Library TCP/IP subsystem
implements IRDP using IP broadcasts rather than IP multicasts.
SUBNETMASK mask-val
specifies that part of the IP address that has to be masked in order to make the
host part of the IP address as a subnet. This is done normally to generate further
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. Since 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.
Default: None.
