2.1 Subsystem Attributes

$ TCPIP

TCPIP> sysconfig -s

cm: loaded and configured

inet: loaded and configured

iptunnel: loaded and configured

ipv6: loaded and configured

net: loaded and configured

snmpinfo: loaded and configured

socket: loaded and configured

inetkvci: loaded and configured

proxy: loaded and configured

nfs: loaded and configured

vfs: loaded and configured

Note

Depending on the conﬁguration of your system, the list of subsystems

displayed may differ from this example.

2.1.1.1 Static and Dynamic Subsystems

There are two types of subsystems:

• Static subsystems are loaded at startup time and can be unloaded only when

TCP/IP shuts down.

• Dynamic subsystems can be loaded and unloaded at will without shutting

down and restarting TCP/IP Services.

You can use the

sysconfig -m

command to display static and dynamic

subsystems, as follows:

$ TCPIP

TCPIP> sysconfig -m

cm: static

inet: static

iptunnel: static

ipv6: static

net: static

snmpinfo: static

socket: static

inetkvci: static

proxy: static

nfs: static

vfs: static

Subsystems can be loaded but not available for use. Subsystems can have the

following states:

• Loaded and conﬁgured (available for use)

• Loaded and unconﬁgured (not available for use)

This state applies only to static subsystems, which you can unconﬁgure, but

you cannot unload.

• Unloaded (not available for use)

This state applies only to loadable subsystems, which are automatically

unloaded when you unconﬁgure them.
