Figure 1-15 shows interface numbering in a Cisco ASR 903 router.
Figure1-15 CiscoASR 903 router Slot Numbers
Following is an explanation of the slot or port numbering:
•The numbering f ormat is Interface type slot or interface number. Interface (port ) numbers begin a t
logical 0 for each interface type.
•Interface module slots are numbered from bottom to top, with logical interfaces on each module
numbered from left to right. Interfaces are hard-wired. Therefore, port 0 is always logical interface
0/0, port 1 is always logical interface 0/1, and so on.
