Configuring SilkWorm 12000, 24000, and 48000
Directors
This chapter contains procedures that are specific to SilkWorm 12000, 24000, and 48000 Directors.
Because directors contain interchangeable 16-port blades (32-port blades in the SilkWorm 48000), their
procedures differ from those for SilkWorm 200E, 3016, 3250, 3850, 3900, 4012, and 4100 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 SilkWorm 12000 director comprises two logical switches (domains), and the
SilkWorm 24000 and 48000 directors in their default configurations have only one domain (SilkWorm
48000 supports one domain only), procedures for the directors sometimes differ from one another.
For detailed information about the SilkWorm 12000, 24000, and 48000 models, refer to the SilkWorm
12000 Hardware Reference, the SilkWorm 24000 Hardware Reference, and the SilkWorm 48000
Hardware Reference.
For detailed information about migrating a SilkWorm director and supported migration paths, refer to
the SilkWorm Director Blade Support Notes.
Identifying Ports
SilkWorm 12000, 24000, and 48000 models 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 numbers 5 and 6 contain control processor blades (CPs).
• Slot numbers 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 SilkWorm 48000:
• 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 SilkWorm 12000 is divided into two logical switches, where slot 1 through 4 is logical switch 0
(sw0) and slot 7 through 10 is logical switch 1 (sw1). You must be connected to the logical switch that
represents the slot where you want to execute a command.
