Using the CLI 225
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/N2100-ON/N3000 switches always use the TwentyGigabitStacking or
Tw notation and on the N1100-ON/N1500/N4000 switches, are referred to
using Ethernet notation.
Loopback Interfaces
Loopback interfaces are represented in the CLI by the keyword loopback
followed by the variable loopback-id, which can assume values from 0–7.
Port Channel Interfaces
Port-channel (or LAG) interfaces are represented in the CLI by the keyword
port-channel followed by the variable port-channel-number.
