Enabling 8X Ports
Users can enable 8X (10 Gbps) ports by combining two (2) 4X ports together (also
known as a “DUO”). The first port in a DUO is known as the master port; the
second port is the partner or slave port. The following CLI commands can enable
8x ports:
 ismPortSetWidth: sets the supported link width for an individual IB port.
 ismChassisSetWidth: sets the supported link width for all chassis IB
ports.
 ismIslSetWidth: sets the supported link width for all interswitch link (ISL)
IB ports. This command is only available 12800-series switches.
Creating an 8x Port: 12200/12300
For the 12200 and 12300 switches, 8x DUOs are set up by combining the 4X port
on the bottom row with the 4X port directly above it (for example, port 1 with port
19, port 2 with 20, port 3 with port 21, etc.):
Figure 1-48. 12200/12300 8x DUOs
For example, to combine ports 2 and 20:
1. Log into the switch CLI with the login admin and password adminpass.
2. Enable port 2 with a command similar to:
ismPortSetWidth Cable02 7 -bounce.
and press Enter.
3. Enable port 20 using same command as above, changing the port number
(that is, Cable20).
NOTE:
This section focuses on enabling 8x external cable ports. For details on each
command, refer the QLogic 12000 CLI Reference Guide.
