196 Configuring Directors
Director port numbering schemes
Table 51 lists the port numbering schemes for the 4/256 Director and DC Director.
The following sections tell how to identify ports on 4/256 Director and DC Director models, and how to
identify ports for zoning commands.
By slot and port number
The port number is a number assigned to an external port to give it a unique identifier in a switch.
To select a specific port in the 4/256 Director and DC Director models, 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.
The following example shows how to enable port 4 on a blade in slot 2:
switch:admin> portenable 2/4
By port area ID
The relationship between the port number and area ID depends upon the PID format used in the fabric.
When Core PID format is in effect, the area ID for port 0 is 0, for port 1 is 1, and so forth.
For 32-port blades (FC4-32, FC8-32), the numbering is contiguous up to port 15; from port 16, the
numbering is still contiguous, but starts with 128. For example, port 15 in slot 1 has a port number and
area ID of 15; port 16 has a port number and area ID of 128; port 17 has a port number and area ID of
129.
For 48-port blades (FC4-48, FC8-48), the numbering is the same as for 32-port blades for the first 32 ports
on the blade. For ports 32 through 47, area IDs are not unique and port index should be used instead of
area ID.
If you perform a port swap operation, the port number and area ID no longer match. On 48-port blades,
port swapping is supported only on ports 0–15.
To determine the area ID of a particular port, enter the switchShow command. This command displays
all ports on the current (logical) switch and their corresponding area IDs.
By index
With the introduction of 48-port blades, indexing was introduced. Unique area IDs are possible up to 255
areas, but beyond that there needed to be some way to ensure uniqueness.

Port blades Numbering scheme
FC2-16
FC4-16
FC8-16
Ports are numbered from 0 through 15 from bottom to top.
FC4-32
FC8-32
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.
FC4-48
FC8-48
Ports are numbered from 0 through 23 from bottom to top on the left set of ports and 24
through 47 from bottom to top on the right set of ports.
FC10-6 Ports are numbered from 0 through 5 from bottom to top.
FC4-16IP Fibre Channel ports are numbered from 0 through 7 from bottom to top. There are also
eight GbE ports (numbered ge0 – ge7, from bottom to top). Going from bottom to top, the
eight FC ports appear on the bottom, followed by the eight GbE ports at the top.
FR4-18i Ports are numbered from 0 through 15 from bottom to top. There are also two GbE ports
(numbered ge0-ge1, from bottom to top). Going from bottom to top, the two GbE ports
appear on the bottom of the blade followed by sixteen FC ports.
