Managing Network Datalinks in Oracle^® Solaris 11.3

Use Case: Configuring Bandwidth for VLAN VNICs

This section shows an example to show how to configure bandwidth limit on the VLAN VNICs to provision the bandwidth of the physical link among the VLAN VNICs. In this example, there are three services running in different zones, which share the same physical link.

1. Check the available links and create the VNIC VLANs over a specific link.

   root@solaris# dladm show-link
   LINK     CLASS     MTU     STATE     OVER
   net0     phys      1500    up        --         
   root@solaris# dladm create-vnic -v 10 -l net0 vnic_prod
   root@solaris# dladm create-vnic -v 11 -l net0 vnic_repl
   root@solaris# dladm create-vnic -v 12 -l net0 vnic_bkup
   root@solaris# dladm show-vnic
   LINK          OVER    SPEED   MACADDRESS         MACADDRTYPE   IDS
   vnic_prod     net0    1000    2:8:20:35:b:9a     random        VID:10      
   vnic_repl     net0    1000    2:8:20:fa:94:57    random        VID:11 
   vnic_bkup     net0    1000    2:8:20:51:1c:4a    random        VID:12

2. Assign bandwidth to all the VNICs.

   root@solaris# dladm set-linkprop -p maxbw=1G vnic_prod
   root@solaris# dladm set-linkprop -p maxbw=500M vnic_repl
   root@solaris# dladm set-linkprop -p maxbw=200M vnic_bkup

3. Create a zone named zone1 and assign a VLAN VNIC to it.

   root@solaris# zonecfg -z zone1
   Use 'create' to begin configuring a new zone.
   zonecfg:zone1> create -t SYSsolaris
   zonecfg:zone1> add net
   zonecfg:zone1:net> set physical=vnic_prod
   zonecfg:zone1:net> end
   zonecfg:zone1> verify
   zonecfg:zone1> commit
   zonecfg:zone1> exit
   root@solaris# zoneadm -z zone1 boot

4. Log in to zone1 and configure the VNIC with an IP address.

   root@solaris# zlogin zone1
   root@zone1# ipadm create-ip vnic_prod
   root@zone1:~# ipadm create-addr -a 192.0.2.1 vnic_prod
   vnic_prod/v4
   root@solaris# zoneadm -z zone1 reboot

5. Create a zone named zone2 and assign a VLAN VNIC to it.

   root@solaris# zonecfg -z zone2
   Use 'create' to begin configuring a new zone.
   zonecfg:zone2> create -t SYSsolaris
   zonecfg:zone2> add net
   zonecfg:zone2:net> set physical=vnic_repl
   zonecfg:zone2:net> end
   zonecfg:zone2> verify
   zonecfg:zone2> commit
   zonecfg:zone2> exit
   root@solaris# zoneadm -z zone2 boot

6. Log in to zone2 and configure the VNIC with an IP address.

   root@solaris# zlogin zone2
   root@zone2# ipadm create-ip vnic_repl
   root@zone2:~# ipadm create-addr -a 192.0.2.1 vnic_repl
   vnic_repl/v4

7. Create a zone named zone3 and assign a VLAN VNIC to it.

   root@solaris# zonecfg -z zone3
   Use 'create' to begin configuring a new zone.
   zonecfg:zone3> create -t SYSsolaris
   zonecfg:zone3> add net
   zonecfg:zone3:net> set physical=vnic_bkup
   zonecfg:zone3:net> end
   zonecfg:zone3> verify
   zonecfg:zone3> commit
   zonecfg:zone3> exit
   root@solaris# zoneadm -z zone3 boot

8. Log in to zone3 and configure the VNIC with an IP address.

   root@solaris# zlogin zone3
   root@zone3# ipadm create-ip vnic_bkup
   root@zone3:~# ipadm create-addr -a 192.0.2.1 vnic_bkup
   vnic_bkup/v4

In the example, one VLAN VNIC is assigned for each service in the zones. The bandwidth of the VNIC is configured to provision the bandwidth of the physical link. This ensures that the available network resources are efficiently used.
