CLI Reference Guide

Using the CLI 187
• Port # — The port number is an integer number assigned to the physical
port on the switch and corresponds to the lexan printed next to the port on
the front or back panel. Ports are numbered from 1 to the maximum
number of ports available on the switch, typically 24 or 48.
Within this document, the tag interface–id refers to an interface identifier
that follows the naming convention above.
Table 2-4. Interface Identifiers
When listed in command line output, gigabit Ethernet interfaces are
preceded by the characters
Gi , ten-gigabit Ethernet interfaces are preceded by
Te , and forty-gigabit Ethernet interfaces are preceded by Fo, as shown in the
examples below.
Stacking Interfaces
Stacking interfaces are represented in the CLI with the same unit/slot/port
form as Ethernet interfaces. The fixed stacking interfaces on the
N2000/N3000 switches always use the TwentyGigabitStacking or Tw notation
and on the N4000 switches, are referred to using Ethernet notation.
Loopback Interfaces
Loopback interfaces are represented in the CLI by the variable loopback-id ,
which can assume values from 0–7.
