Hi Mike and all,

Thanks for your previous replies. Sorry for the late reply.

I have run into problems with VLAN tagging now. Can you please check whether 
its a config problem or limitation on IPMP on FAILED interfaces.

ss44bsdvzgza02# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 
index 1
        inet netmask ff000000 
bge604000: flags=211000803<UP,BROADCAST,MULTICAST,IPv4,FAILED,CoS> mtu 1500 
index 2
        inet netmask fffffe00 broadcast
        groupname global
        ether 0:3:ba:c8:7d:35 
mtu 1500 index 2
        inet netmask fffffe00 broadcast
 mtu 1500 index 3
        inet netmask fffffe00 broadcast
        groupname global
        ether 0:3:ba:c8:7d:36 

NOTE: Interfaces are in FAILED mode due to cables not plugged in yet. Also, no 
default router.

Now trying to configure zone with VLAN tagged.

zonecfg:sz44bsdvapdqc02> create
zonecfg:sz44bsdvapdqc02> set autoboot=true
zonecfg:sz44bsdvapdqc02> set zonepath=/export/zone/dvapdqc02
zonecfg:sz44bsdvapdqc02> add net 
zonecfg:sz44bsdvapdqc02:net> set physical=bge604000
zonecfg:sz44bsdvapdqc02:net> set address=
zonecfg:sz44bsdvapdqc02:net> end
zonecfg:sz44bsdvapdqc02> info

ss44bsdvzgza02# zoneadm -z sz44bsdvapdqc02 boot
 zoneadm: zone 'sz44bsdvapdqc02': bge604000:2: could not set default interface 
for multicast: Invalid argument
zoneadm: zone 'sz44bsdvapdqc02': call to zoneadmd failed

Seen on Sunsolve if IPMP interfaces are on FAILED mode then none-global zones 
may have trouble booting. Has this been fixed ?
