Ports on the Core Switch 2/64
In previous versions of the Fabric OS (v2.x and v3.x), the primary method for
identifying a port within the fabric was the "
domain,port " combination.
The following example shows the zoneadd command where a port is identified
using the domain, and port number.
Example
The former method of specifying a particular port cannot be used in the Core
Switch 2/64 because of the addition of slots and variable number of ports within a
domain. It was replaced in Fabric OS v4.0 by two methods to specify a particular
port:
■ The slot/port method
■ The port area number method. The port area method is only used when
implementing zoning commands.
