Example of Interface Numbering
Example of Interface Numbering
Figure1-5 shows a Catalyst8540MSR chassis populated with several half-width port adapters and full-width interface modules. In this example, 12/0/3 is called out in the last interface module installed in the chassis. The 12/0/3 interface number is derived by:
•Card (12)—The interface module is in the thirteenth slot of the chassis; therefore, the card number is 12. (Card numbering starts at 0 and increments by 1 from top to bottom.)
•Subcard (0)—The full-width interface module is the only subcard within the twelfth slot; therefore, the subcard number is 0.
•Port (3)—The callout points to the fourth port on the interface module; therefore, the port number is 3. (Port numbering starts at 0 and increments by 1 from left to right.)
