A netmask setting is not available when creating a zone, and the /etc/netmasks file is not consulted when plumbing up zone interfaces. This tech-recipe describes how to force a netmask when creating a zone.

If a network interface was configured with the wrong subnet mask as can happen when the default subnet is selected with a variable length subnet mask, a simple configuration change will fix it.

Solaris allows multiple virtual or logical interfaces to exist with different IP addresses on the same physical interface. Virtual interfaces are created or plumbed up using the plumb directive in ifconfig. They are unplumbed using the unplumb directive.

When troubleshooting networking issues, it is often helpful to determine the state of an ethernet interface. Solaris offers access to many configurable networking parameters through ndd.

Solaris can request IP address and other networking information dynamically with DHCP.

Virtual interfaces allow a single ethernet interface to listen on additional IP addresses.

Simply, these are the examples of the commands used to view the routing table in Solaris.
