number.
The Core Switch 2/64 has a total of 10 slots counted 1 to 10. Refer to
The Core Switch 2/64 is divided into two logical switches, where slots 1 through 4
are logical switch 0 and slots 7 through 10 are logical switch 1. Typically you
must be logged in to the logical switch that represents the slot where you want to
execute a command.

About the Port Area Number Method

Some commands, such as the Zoning commands require you to specify ports
using the Area Number method. In the Fabric OS v4x, each port on a particular
domain is given a unique Area ID.
The Core Switch 2/64 chassis contains two logical switches. The Area IDs for
both logical 64-port switches range from 0 to 63. This means that both logical
switch 0 and logical switch 1 have a port that is referenced with Area ID 0.
An Area ID for each port is unique inside each logical switch (that is, each
assigned domain ID). These are two of the three parts of a 24-bit Fibre Channel
Address ID: 8-bit Domain ID, 8-bit Area ID, 8-bit Port ID.
Use the switchshow command to display all ports on the current (logical) switch
and their corresponding Area IDs.

Determining the Area Number (ID) of a Port

To determine the Area ID of a particular port:
1. Log into the switch as the admin user.
2. Enter the switchshow command at the command line. This command

No spaces are allowed between the slot number, the slash (/), and the port
Slots number 5 and 6 are control processor cards
Slots 1 through 4 and 7 through 10 are switch cards.
On each switch card, there are 16 ports counted from the bottom 0 to 15. A
particular port must be represented by both slot number (1 though 10) and port
number (0 through 15).
