Configuring VLANs

If you are using the earlier Solaris 10 3/05, refer to Configuring VLANs in Solaris 10 3/05 ONLY.

Oracle Solaris now supports VLANs on the following interface types:

• ce

• bge

• xge

• e1000g

Of the legacy interface types, only the ce interface can become a member of a VLAN. You can configure interfaces of different types in the same VLAN.

You can configure multiple VLANs into an IPMP group. For more information about IPMP groups, see IPMP Interface Configurations.

How to Configure a VLAN

If you are using Solaris 10 3/05, use the procedure How To Configure Static VLANs in Solaris 10 3/05 ONLY.

1. Assume the Primary Administrator role, or become superuser.

   The Primary Administrator role includes the Primary Administrator profile. To create the role and assign the role to a user, see Chapter 2, Working With the Solaris Management Console (Tasks), in System Administration Guide: Basic Administration.

2. Determine the types of interfaces in use on your system.

   # dladm show-link

   The output shows the available interface types:

   ce0 type: legacy mtu: 1500 device: ce0 ce1 type: legacy mtu: 1500 device: ce1 bge0 type: non-vlan mtu: 1500 device: bge0 bge1 type: non-vlan mtu: 1500 device: bge1 bge2 type: non-vlan mtu: 1500 device: bge2

3. Configure an interface as part of a VLAN.

   # ifconfig interface-PPA plumb IP-address up

   For example, you would use the following command to configure the interface ce1 with a new IP address 10.0.0.2 into a VLAN with the VID 123:

   # ifconfig ce123001 plumb 10.0.0.2 up

   ---

   Note –

   You can assign IPv4 and IPv6 addresses to VLANs just as you do to other interfaces.

   ---

4. (Optional) To make the VLAN settings persist across reboots, create a hostname.interface-PPA file for each interface that is configured as part of a VLAN.

   # cat hostname.interface-PPA IPv4-address

5. On the switch, set VLAN tagging and VLAN ports to correspond with the VLANs that you have set up on the system.

Example 6–3 Configuring a VLAN

This example shows how to configure devices bge1 and bge2 into a VLAN with the VID 123.
