Zone with multiple logical interfaces

Question

Hi,
How can multiple logical network interfaces be added to a running zone?
I have configured and installed a whole root zone with one shared-ip network interface.
Now, I need to add more logical interfaces to the same zone.
On a physical server with a bge interface, I would create a /etc/hostname file for each logical interface such as
$ ls /etc | grep host
hostname.bge0
hostname.bge0:1
hostname.bge0:2
hostname.bge0:3
hostname.bge0:4
hostname.bge1
hostname.bge1:1
hostname.bge1:2
hostname.bge1:3
hostname.bge3
hosts
$How can the above be done for a zone?

Hi
This requires 2 steps. Firstly update your zone configuration to add the logical interface and its associated IP address.
Assuming from below you want the logical interface to be added to bge0 then do the following replacing the zonename and ip address for whatever is appropriate for you.
# zonecfg -z itchyzone
zonecfg:itchyzone1> add net
zonecfg:itchyzone1:net> set address=192.168.1.21
zonecfg:itchyzone1:net> set physical=bge0
zonecfg:itchyzone1:net> end
zonecfg:itchyzone1> exitYou can do the above as many times as you like to create multiple logical interfaces for the zone.
After doing the above you will need to reboot the zone to get the new logical interface.
However if you cant reboot the zone you can plumb a logical interface into the zone by running something similar to the following (change for your zonename, IP etc) from the global zone:
# ifconfig bge0 addif 192.168.1.21 netmask + broadcast + zone itchyzone1 upyou will now have an extra interface in the zone (in this case called itchyzone1). To verify, login to the zone and run ifconfig -a and you will see your new interface.
# zlogin itchyzone1
