ADD SUBNET Command for TCPMAN
FAILOVER {SHAREDIP | NONSHAREDIP}
enables the SUBNET to be failover-capable using the following configuration:
•
SHAREDIP has the same IP address as the associated SUBNET in the
failover configuration.
•
NONSHAREDIP has a different IP address than the associated SUBNET in the
failover configuration.
Examples
The first example adds a subnet named SN1 of type Ethernet to all the TCPMONs in
the system. The second example adds a subnet named SN4 to all the TCPMONs in
the system. Note that in the second example, a subnet mask value has been specified,
which was not possible in conventional TCP/IP. (In conventional TCP/IP, you had to
alter the added subnet to add the subnet mask value.)
-> ADD SUBNET $ZZTCP.*.SN1, TYPE ETHERNET, DEVICENAME LAN02, &
IPADDRESS 50.0.0.3
-> ADD SUBNET $ZZTCP.*.SN4, TYPE ETHERNET, DEVICENAME LAN04, &
IPADDRESS 50.0.0.1, SUBNETMASK %HFFFF0000
The first of the following examples adds a SUBNET and associated SUBNET with
failover enabled for non-shared IP addresses and the second example adds them for
shared IP addresses:
-> ASSUME PROCESS $ZZTCP
-> ADD SUBNET SN1, TYPE ETHERNET, DEVICENAME LANLIF2, IPADDRESS
172.17.217.232, SUBNETMASK 255.255.255.0, FAILOVER NONSHAREDIP
-> ADD SUBNET SN2, TYPE ETHERNET, DEVICENAME LANLIF3, IPADDRESS
172.17.217.234, SUBNETMASK 255.255.255.0, FAILOVER NONSHAREDIP
-> ADD SUBNET SN3, TYPE ETHERNET, DEVICENAME LANLIF4, IPADDRESS
172.17.217.44, SUBNETMASK 255.255.255.0, FAILOVER SHAREDIP
-> ADD SUBNET SN4, TYPE ETHERNET, DEVICENAME LANLIF5, IPADDRESS
172.17.217.44, SUBNETMASK 255.255.255.0, FAILOVER SHAREDIP
Considerations
•
You can add up to 64 subnets in the Parallel Library TCP/IP environment.
•
When you add a subnet, you must do so to all configured TCPMONs. Hence, only
the wild card (*) is supported for the TCPMON name. The wild card, however, is
optional; if you do not specify it, the wild card is assumed.
•
Unlike conventional TCP/IP, you can now specify a subnet mask value in the ADD
SUBNET command.
•
When you specify the name of the route or subnet you are adding, be sure to
specify the process name in the ASSUME command or in the ADD command, as
shown in the examples. Verify that the name is unique for that process.
