ADD SUBNET Command for TCP6MAN
FAILOVER {SHAREDIP | NONSHAREDIP}
enables the SUBNET to be failover-capable using these configurations:

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.
MTU size
alters the maximum transfer unit (MTU) for messages that the system transmits on
the link. The minimum value is 512 bytes. The maximum value is 65535 bytes. The
actual maximum value is determined from the interface with SLSA as the PIF's
Max_Frame_Size - 14. The value 14 is subtracted because MTU does not include
the Ethernet header overhead of 14 bytes.
LNPTPLIST "tcp6sam list"
specifies that this SUBNET is part of a logical network partition and specifies the
transport-service provider processes (TCP6SAM processes) that provide access
for this partition. If this attribute is not specified, this SUBNET is part of the default
LNP. The maximum number of TCP6SAM processes for a configured LNP is two.
The list is specified in quotations with the TCP6SAM processes separated by a
comma. For example:
LNPTPLIST "$ZSAM1, $ZSAM2"
IPv4 Examples

To add a SUBNET named SN1 of type Ethernet to all the TCP6MONs in the
system:
-> ADD SUBNET $ZZTCP.*.SN1, TYPE ETHERNET, DEVICENAME L02A, &
IPADDRESS 50.0.0.3
To add a SUBNET named SN4 to all the TCP6MONs in the system:
-> ADD SUBNET $ZZTCP.*.SN4, TYPE ETHERNET, DEVICENAME L104, &
IPADDRESS 50.0.0.1, SUBNETMASK %HFFFF0000
To add a SUBNET for a configured LNP:
-> ADD SUBNET $ZZTCP.*.SN1, TYPE ETHERNET, DEVICENAME L019, &
IPADDRESS 50.0.0.4, LNPTPLIST "$ZSAM1, $ZSAM2"

To add a SUBNET and associated SUBNET with failover enabled for nonshared 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
