ldom rebooted- interface comes up with wrong netmask - Solaris 10
vnet5: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 4
inet 10.10.10.171 netmask ffffff00 broadcast 10.10.10.255
ether 0:14:4f:fa:4:64
# cat /etc/hostname.vnet5
10.10.10.171 netmask 255.255.0.0 up
How on earth is this even possible after reboot?
Couple of things probaby no relevant - NIS and interface used to be part of IPMP group.
At the moment, only way to get it working is to unplumb then manually do "ifconfig vnet5 10.10.10.171 plumb netmask 255.255.0.0 up"
