Solaris 10 network interfaces issue


I encountered a problem today with my Solaris 10 server. I have 8 zones running on it, i also have 4 network interfaces (e1000g0,e1000g1,e1000g2,e1000g3).

e1000g0 : unused
e1000g1      : global zone shared with multiple non global zones        ( /27)
e1000g2      : exlusive to a non global zone                          ( /27)
e1000g3 : exlusive to a non global zone                          ( /27)

e1000g1,e1000g2,e1000g3 are in the same subnet, so today i wanted to configure e1000g0 with a different subnet ( /28) to install new zones.

here's what i did:

ifconfig e1000g0 plumb up
ifconfig e1000g0 netmask +

Immediately after that i lost the ssh connection and i could not ping my physical server I realized after a moment that i could connect via ssh and ping my physical server with the new ip address I unplumbed e1000g0 and things got back to normal.

What's wrong? why this happened ? I would just like to have new zones with a different subnet and keep the ip address of the globale zone (

You need to specify broascast address, may be zonename as well. So try this:

ifconfig e1000g0 netmask broascast zone zonename
