Ports
3
When you have port blades with different port counts in the same Backbone (for example, 16-port
blades and 32-port blades, or 16-port blades and 18-port blades with 16 FC ports and 2 GbE ports,
or 16-port and 48-port blades), the area IDs no longer match the port numbers.
Table 6 on page 45 lists the port numbering schemes for the blades.
Setting port names
Perform the following steps to specify a port name. For Backbones, specify the slot number where
the blade is installed.
1. Connect to the switch and log in using an account with admin permissions.
2. Enter the portName command.
Example of naming port 0
ecp:admin> portname 1/0 trunk1
Port identification 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 Backbones, 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.
Example of enabling port 4 on a blade in slot 2
ecp:admin> portenable 2/4
Port identification 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 (FC8-32, FC8-32E, FC16-32), 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 (FC8-48, FC8-48E, FC16-48), 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.
For the 64-port blade (FC8-64), the numbering is the same as for 32-port blades for the first 32
ports on the blade. For ports 32 through 64, 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.
