Solaris 11 Networks
The following are some notes so I don’t forget what I did with Solaris 11 on given hosts:
- I’ve got a single host with a few interfaces connected to a switch
- I’ve added link aggregation (but only with single interfaces) in front of the physical. This is for a later project where I’ll be looking at link aggregation and LACP.
- I’d like to run a few zones on 2 of the interfaces/aggrs.
- the first interface is connected to a DMZ for external facing connectivity
- the second interface is connected to an internal VLAN for local services
- on another interface, I’d like to create an ip interface for connecting to the host for management
Its worth noting that if you’ve got an aggr with an ip interface attached to it, the datalink is in use. This means that you can’t move zone vnics to this aggr. In order to move vnics to this aggr, apparently you must delete the ip interface first.
root@solaris-test:~# dladm LINK CLASS MTU STATE OVER net0 phys 1500 up -- net1 phys 1500 up -- net2 phys 1500 up -- extapps0 aggr 1500 up net1 intapps0 aggr 1500 up net2 root@solaris-test:~# ipadm NAME CLASS/TYPE STATE UNDER ADDR lo0 loopback ok -- -- lo0/v4 static ok -- 127.0.0.1/8 lo0/v6 static ok -- ::1/128 net0 ip ok -- -- net0/v4 dhcp ok -- 10.0.2.15/24 net0/v6 addrconf ok -- fe80::a00:27ff:fe31:ae8c/10
A further complication emerges when you create a zone and boot it. The zone creates a temporary vnic object associated with the zone. Unfortunately, it appears one can’t move this temporary vnic between aggrs as you can with vnics created in dladm in the global zone.
The solution appears to be to create a vnic in dladm and set this as the physical interface in the net config of the zone. After removing the default anet.
Then configure the network in the zone as required.
