Gigabit Ethernet Management
Cisco 4000 Series ISRs provides a Gigabit Ethernet Management port, called GE0. This port is the only
1-tuple port on the system. See the
Configuration Guide for the Cisco ISR 4400 Series and Cisco ISR 4300 Series Routers
information about the Gigabit Ethernet Management port.

SFP 2/Gigabit Ethernet port (GE 0/0/2)
RJ-45 Gigabit Ethernet port GE 0/0/3
Slot 0 is the motherboard and not removable. It is reserved for integrated ports and NIMs.
NIMs are designated by the number of the first slot that they occupy. A double-wide NIM occupies
two slots, but its designation is only the left-most slot number.
The front panel GE ports (or native interface ports) always reside in slot 0 and bay 0. The ports are
called Gigabitethernet 0/0/0, Gigabitethernet 0/0/1, Gigabitethernet 0/0/2, and Gigabitethernet 0/0/3
(up to as many ports supported on the particular router).
PVDM4s do not have an external slot number. Therefore, the nomenclature for PVDM4s always has
0 in the first tuple. For example, the 3-tuple for an PVDM4 can be 0/4/x.
Integrated devices, also known as integrated ports or FPGEs, and integrated NIMs reside in a fixed
section of bay 0.
Main board NIMs bays start at bay 1, because the integrated devices and integrated NIMs take up
bay 0.
The bay numbers for PVDM4s start with the next bay number after the last NIM bay number.
