Sun Microsystems 10 manual Network, Change network configuration for shared IP instances

5.2.1. Change network configuration for shared IP instances

[dd]For an already configured zone with a shared IP instance, it may be necessary to change the physical interface or the network address.

global# zonecfg -z zone1 zonecfg:zone1> info net net:

address: 192.168.1.1/24

physical: bge1 zonecfg:zone1> select net physical=bge1 zonecfg:zone1:net> set physical=bge0 zonecfg:zone1:net> set address=192.168.2.1/24 zonecfg:zone1:net> info

net:

address: 192.168.2.1/24

physical: bge0 zonecfg:zone1:net> end zonecfg:zone1> commit zonecfg:zone1> exit global#

5.2.2. Set default router for shared IP instance

[dd]In the zone configuration, the default router can be specified for a zone with a shared IP instance. Using this configuration option ensures that a certain network route is available in the global zone when a zone is booted (since Solaris 10 11/08)

global# zonecfg -z keetonga zonecfg:keetonga> select net physical=e1000g0 zonecfg:keetonga:net> set defrouter=1.2.3.1 zonecfg:keetonga:net> info

net:

address: 1.2.3.4/24

physical: e1000g0

defrouter: 1.2.3.1 zonecfg:keetonga:net> end

5.2.3. Network interfaces for exclusive IP instances

[dd]In order to use exclusive IP instances, GLDv3-driver enabled network interfaces or tagged VLAN interfaces are required and are collectively termed GLDv3-interfaces below. These drivers include: bge, ce, e1000g, eri, hme, ixgb, nge, nxge, rge, xge. Further details on supported adapters can be found at: http://opensolaris.org/os/project/crossbow/faq/#ip_instances. The adapters in the system can be displayed with dladm show-link.

Each exclusive IP instance must have a physical interface or a tagged VLAN interface assigned. Therefore, the required number of interfaces results from the number of zones with an exclusive IP instance required. If tagged VLAN interfaces are used, the maximum number of zones within a VLAN results in the number of physical interfaces required. The reason for this lies in the creation rule for tagged VLAN interfaces:

Interface = Interfacename<instance + (VLAN-ID * 1000)>

e.g. bge1000 uses the VLAN with ID 1 on bge0 or

bge4003 uses the VLAN with ID 4 on bge3
