Configuring Core Switch 2/64, SAN Director

2/128, and 4/256 SAN Director

This chapter contains procedures that are specific to the Core Switch 2/64, SAN Director 2/128, and

4/256 SAN Director.
Because directors contain interchangeable 16-port blades (32-port blades in the 4/256 SAN Director),

their procedures differ from those for the 4/8 SAN Switch, 4/16 SAN Switch, SAN Switch 2/8V, SAN

Switch 2/16V, SAN Switch 2/32, Brocade 4Gb SAN Switch for HP p-Class BladeSystem, and SAN

Switch 4/32 fixed-port switches. For example, fixed-port models identify ports by domain,port number,

while director models identify ports by slot/port number.
Also, because the Core Switch 2/64 director comprises two logical switches (domains), and the SAN

Director 2/128 and 4/256 SAN Director in their default configurations have only one domain (the

4/256 SAN Director supports only one domain), procedures for the directors sometimes differ from one

another.
For detailed information about the Core Switch 2/64, SAN Director 2/128, and 4/256 SAN Director,

see the installation guide for the switch.

Identifying ports

The Core Switch 2/64, SAN Director 2/128, and 4/256 SAN Director have slots and can have a

variable number of ports within a given domain. Ports are identified by their combined slot number and

port number.
There are 10 slots that contain port blades:

Slot 5 and 6 contain CP blades.

Slot 1 through 4 and 7 through 10 contain port blades.

On each port blade, there are 16 or 32 ports (counted from the bottom, 0 to 15, or 0 to 31). A particular

port must be represented by both slot number (1 through 4 and 7 through 10) and port number (0 through

15).
When you have port blades with different port counts in the same director (for example, 16-port blade

and 32-port blades), the area IDs no longer match the port numbers. Following are the port numbering

schemes for the 4/256 SAN Director:

For the FC4-16 port blade, ports are numbered from 0 through 15 from bottom to top.

For the FC-32 port blade, ports are numbered from 0 through 15 from bottom to top on the left set of

ports and 16 through 31 from bottom to top on the right set of ports.

The Core Switch 2/64 is divided into two logical switches, where slots 1 through 4 constitute logical

switch 0 (sw0) and slots 7 through 10 constitute logical switch 1 (sw1). You must be connected to the

logical switch that represents the slot where you want to execute a command.
In the SAN Director 2/128 and 4/256 SAN Director default configuration, all the ports are part of a

single logical switch. With Fabric OS 4.4.0 and later, you can configure the SAN Director 2/128 as two

logical switches (domains).
The following sections tell how to identify ports on the Core Switch 2/64, SAN Director 2/128, and

4/256 SAN Director, and how to identify ports for zoning commands.

By slot and port number

The port number is assigned to an external port to give it a unique identifier in a switch.
To select a specific port in the Core Switch 2/64, SAN Director 2/128, and 4/256 SAN Director, you

must identify both the slot number and the port number using the format slot number/port number. No

spaces are allowed between the slot number, the slash (/), and the port number.
