Combining Network Configuration Tasks While Using Customized Names
This section provides an example that combines all the procedures in the previous chapters about configuring links, VLANs, and link aggregations while using customized names. For a description of other networking scenarios that use customized names, see the article in http://www.sun.com/bigadmin/sundocs/articles/vnamingsol.jsp.
Example 6–7 Configuring Links, Aggregations, and VLANs
In this example, a system that consists of 4 NICs needs to be configured to be a router for 8 separate subnets. To attain this objective, 8 links will be configured, one for each subnet. First, a link aggregation is created on all 4 NICs. This untagged link becomes the default untagged subnet for the network to which the default route points.
Then VLAN interfaces are configured over the link aggregation for the other subnets. The subnets are named by basing on a color-coded scheme. Accordingly, the VLAN names are likewise named to correspond to their respective subnets. The final configuration consists of 8 links for the eight subnets: 1 untagged link, and 7 tagged VLAN links.
To make the configurations persist across reboots, the same procedures apply as in previous Solaris releases. For example, IP addresses need to be added to configuration files like /etc/inet/ndpd.conf or /etc/hostname.interface. Or, filter rules for the interfaces need to be included in a rules file. These final steps are not included in the example. For these steps, refer to the appropriate chapters in System Administration Guide: IP Services, particularly TCP/IP Administration and DHCP.
