You can use the dladm show-link command to display information about VLANs because VLANs are datalinks. Use the dladm show-vlan command to display specific information about the VLANs.
The following example compares the type of information that you can obtain by using either the dladm show-link or dladm show-vlan command. The first example uses the dladm show-link command to display all of the datalinks on the system, including those that are not VLANs. The second example uses the dladm show-vlan command to display a subset of the datalink information that is relevant only to VLANs.
# dladm show-link LINK CLASS MTU STATE OVER net0 phys 1500 up -- net1 phys 1500 up -- net2 phys 1500 up -- web1 vlan 1500 up net0 auth1 vlan 1500 up net0 app1 vlan 1500 up net0 web2 vlan 1500 up net1 auth2 vlan 1500 up net1 app2 vlan 1500 up net1 web3 vlan 1500 up net2 auth3 vlan 1500 up net2 # dladm show-vlan LINK VID SVID PVLAN-TYPE FLAGS OVER web1 111 -- -- ---- net0 auth1 112 -- -- ---- net0 app1 113 -- -- ---- net0 web2 111 -- -- ---- net1 auth2 112 -- -- ---- net1 app2 113 -- -- ---- net1 web3 111 -- -- ---- net2 auth3 113 -- -- ---- net2Example 18 Displaying the VLAN IDs That Can be Created on the Datalinks
In Oracle Solaris Kernel Zones, you can use the dladm show-phys command with the –v option to view the VLAN IDs that can be created on each physical datalink.
# dladm show-phys -v
LINK VID INUSE CLIENT
net0 40 yes vnic0,vnic1
20 no --
15 yes vnic2
net1 32 no --
11 no --
10 no --

Example 19 Viewing the Allowed MAC Addresses and Allowed VLAN IDsIn Oracle Solaris Kernel Zones, you can use the dladm show-phys command with the –o option to view the allowed MAC addresses and allowed VLAN IDs as follows:
# dladm show-phys -o link,media,device,allowed-addresses,allowed-vids
LINK MEDIA DEVICE ALLOWED-ADDRESSES ALLOWED-VIDS
net0 Ethernet zvnet0 fa:16:3f, 100-199,
fa:80:20:21:22 400-498,500
