[Solaris 10]Zones and exclusive ip

Tex-Twil · March 13, 2009, 8:23am

Hello,
I have a V120 server with two network interfaces. I would like to use one of them in my non global zone. I set the "ip-type=exclusive" as described here Solaris 10 8/07: Exclusive-IP Non-Global Zones (System Administration Guide: Solaris Containers-Resource Management and Solaris Zones) - Sun Microsystems but it doesn't work.

When I boot my zone, I get the following error:

zoneadm: zone 'myzone': WARNING: unable to hold network interface 'eri1'.:Invalid argument

Further reading brought me to the "An Overview of Solaris 10 Operating System Security Controls" document which say

In order to leverage IP Instances functionality, a Generic Network Driver (GLD) version 3 interface must be used.To determine if a particular network interface is using GLDv3, use the dladm(1M) command:
# dladm show-link 
ce0 type: legacy mtu: 1500 device: ce0 ce1 type: legacy mtu: 1500 device: ce1
If a particular interface reports its type as legacy, then it is not using the GLDv3 framework and therefore cannot be used by IP Instances.

Mine shows:

root@sonne:~$ dladm show-dev
eri0            link: unknown   speed: 100   Mbps       duplex: full
eri1            link: unknown   speed: 100   Mbps       duplex: unknown

So I don't know whether or not it is using the GLDv3 framework or not.

Any ideas how to know this ?

Btw, I have Solaris 10u5.

Thanks in advance,
Tex

show-link != show-dev

Ah ok, my fault.

$ dladm show-link
eri0            type: legacy    mtu: 1500       device: eri0
eri1            type: legacy    mtu: 1500       device: eri1

... so it is not using the GLDv3.
