Using the CLI 227
• 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 unit, typically 24 or 48.
Logical interfaces are identified by one of the keywords: loopback, port-
channel, tunnel or vlan followed an integer index identifying the specific
logical interface.
Within this document, the tag
interface–id refers to a logical or Ethernet
interface identifier that follows the naming convention above. If the
command is restricted to a subset of the interfaces, then the subset is
described in the command description. Ethernet interfaces are
Gigabitethernet, Tengigabitethernet, and Fortygigabitethernet.
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.
