HP-UX IPFilter V18.0 Administrator Guide for HP-UX 11i v3

1. On HP-UX 11i v3 systems, disable HP-UX IPFilter:
/opt/ipf/bin/ipfilter -d
CAUTION: HP recommends that you enable or disable IPFilter when interrupting network
connectivity is not disruptive. Additionally, HP recommends that you do not enable or disable
HP-UX IPFilter when critical network applications are running.
IMPORTANT: Disabling or enabling IPFilter brings down all IP interfaces, and 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.
IMPORTANT: Enabling or disabling IPFilter causes the system to briefly lose network
connectivity. If a system has several IP interfaces or heavy network traffic occurs, 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.
2. Remove HP-UX IPFilter:
