When IPv6 is disabled, Trusted Extensions cannot forward IPv6 packets with CIPSO options. To enable an IPv6 network in Trusted Extensions, you must add an entry in the /etc/system file.
Check that the entry is spelled correctly.
Check that the system has been rebooted after adding the correct entry to the /etc/system file.
If you install Trusted Extensions on a Solaris system that currently has IPv6 enabled, but you fail to add the IP entry in /etc/system, you see the following error message: t_optmgmt: System error: Cannot assign requested address time-stamp
If you install Trusted Extensions on a Solaris system that does not have IPv6 enabled, and you fail to add the IP entry in /etc/system, you see the following types of error messages:
WARNING: IPv6 not enabled via /etc/system
Failed to configure IPv6 interface(s): hme0
rpcbind: Unable to join IPv6 multicast group for rpc broadcast broadcast-number
