Ethernet Interface Naming
An Ethernet interface, or port, is identified by three pieces of information:
» The type (FastEthernet, GigabitEthernet, 2.5GigabitEthernet, 5GigabitEthernet,
10GigabitEthernet)
» The switch it belongs to (for non-stacking systems, this value is always 1)
» The port number within the type and switch (numbering starts with 1 for each type, so a switch
may have both GigabitEthernet 1/1 and 2.5GigabitEthernet 1/1)
Many ICLI commands accept a list of interfaces. In its simplest form, such a list is a sequence of
(type, switch ID, port) information separated by whitespace. For example: GigabitEthernet 1/3
10GigabitEthernet 1/2. This allows a single list to mix different types.
The switch ID and the port numbers can be listed either as single numbers, as lists, or as
sequences. A list is a comma-separated set of single port numbers or sequences, whereas a
sequence is of the form: from—to.
Some examples:
» GigabitEthernet 1/5 for the single gigabit port number 5 on switch 1
» GigabitEthernet 1/2,4,10-12 for gigabit ports 2, 4, 10, 11, 12 on switch 1
» GigabitEthernet 1-3/2 for gigabit port 2 on switches 1, 2 and 3
It is possible to wildcard the type and/or switch ID and/or ports to mean “all types,” “all switch IDs,”
and “all ports,” respectively. A wildcard is written with an asterisk instead of type, switch ID, or
port, and some further abbreviations are possible:
» ‘*’ means “all ports of all types on all switches”
» type ‘*’ means “all ports of the specified type on all switches”
To clarify, several examples are provided. Assume a stack with two switches, switch ID 1 and 3.
Each switch has 9 gigabit ports and two 2.5 gigabit ports. Then:
» interface * (or: interface * * *)
» All ports of all types on all switches: GigabitEthernet 1,3/1-9 2.5GigabitEthernet 1,3/1-2
» interface * 1/2
» Switch 1, port number 2 of all types: GigabitEthernet 1/2 2.5GigabitEthernet 1/2
» interface * */2
» All switches, all types, port number 2: GigabitEthernet 1,3/2 2.5GigabitEthernet 1,3/2
» interface * */4
» All switches, all types, port number 4: GigabitEthernet 1,3/4
