HP-UX IPFilter Version 17 Administrator's Guide

• HP-UX 11i v2
HP-UX IPFilter is installed by default. When installed, HP-UX IPFilter is always enabled.
Use the following steps to load HP-UX IPFilter software using the HP-UX swinstall program.
1. Verify that you have superuser or appropriate capabilities.
2. If the system is an HP-UX 11i v3 system and already has HP-UX IPFilter installed, disable
the existing version:
/opt/ipf/bin/ipfilter -d
CAUTION: HP recommends that you enable or disable IPFilter when interrupting network
connectivity is not disruptive. HP recommends that you do not enable or disable HP-UX
IPFilter when critical network applications are running.
Disabling or enabling IPFilter using briefly brings down all IP interfaces, then brings up
only the IP interfaces configured in the /etc/rc.config.d/netconf and /etc/
rc.config.d/netconf-ipv6 files. IP addresses not configured in the netconf or
netconf-ipv6 file, such as Serviceguard relocatable IP addresses, are not re-enabled.
Enabling or disabling IPFilter causes the system to briefly lose network connectivity. If a
system has several IP interfaces or there is heavy network traffic, the time required to
re-establish network connectivity might be interpreted as a network or card failure. For
example, Serviceguard might interpret a network interruption as a card failure, which can
cause it to reform the cluster.
