Interfaces do not failover
Would anyone know why a V440 Solaris 9 machine's interfaces (ce0 and ce1)
will not failover?
Both interfaces are on the same subnet, but different IPs. I can pull the plug on once interface (ce0) and ce1 will be accessible. I can reverse it and pull ce1, and ce0 will NOT be accessible. This behavior is consistent on all 10 machines, however, its not always the same interface that is the failover-friendly one.
Thanks for any assistance.

ifparse
ifparse(1M) System Administration Commands ifparse(1M)
NAME
ifparse - parse ifconfig command line
SYNOPSIS
/sbin/ifparse [-fs] addr_family commands
DESCRIPTION
Use the ifparse command to parse the ifconfig(1M) command line options and output substrings, one per line, as appropriate. If no options
are specified, ifparse returns the entire ifconfig command line as a series of substrings, one per line.
OPTIONS
The ifparse command supports the following options:
-f Lists only substrings of the ifconfig command line that are relevant to IP network multipath failover
-s Lists only substrings of the ifconfig command line that are not relevant to IP network multipath failover
OPERANDS
The ifparse command does not support the interface operand of the ifconfig command.
EXAMPLES
Example 1: Parsing Command Line Options Relevant to Failover
The following example shows the use of the ifparse command to parse the command line options relevant to IP network multipath failover:
example# ifparse -f inet 1.2.3.4 up group one addif 1.2.3.5 -failover up
set 1.2.3.4 up
Example 2: Parsing Command Line Options That Are Not Relevant to Failover
The following example shows the use of the ifparse command to parse the command line options that are not relevant to IP network multipath
failover:
example# ifparse -s inet 1.2.3.4 up group one addif 1.2.3.5 -failover up
group one
addif 1.2.3.5 -failover up
Example 3: Parsing the Command Line For All Options
The following example shows the use of the ifparse command to parse the command line for all ifconfig options:
example# ifparse inet 1.2.3.4 up group one addif 1.2.3.5 -failover up
group one
set 1.2.3.4 up
addif 1.2.3.5 -failover up

DIAGNOSTICS
usage: -fs <addr_family> <commands>
This message indicates an invalid command line.
ifparse: Not enough space
This message indicates insufficient memory.
ifparse: dhcp not supported for inet6
DHCP operations are not supported for the inet6 address family.
ifparse: Operation <operation> not supported for <addr_family>
Most operations cannot be used with all address families. For example, the broadcast operation is not supported on the inet6 address fam-
ily.
ifparse: no argument for <operation>
Some operations, for example broadcast, require an argument.
NOTES
The ifparse command is classified as an obsolete interface. It will likely be removed in a future release. You should not develop applica-
tions that depend upon this interface.
