Chapter 12 Configuring Interface Characteristics
Using Interface Configuration Mode
•
Stack member number—The number that identifies the switch within the stack. The switch number
range is 1 to 9 and is assigned the first time the switch initializes. The default switch number, before
it is integrated into a switch stack, is 1. When a switch has been assigned a stack member number,
it keeps that number until another is assigned to it.
You can use the switch port LEDs in Stack mode to identify the stack member number of a switch.
For information about stack member numbers, see the “Stack Member Numbers” section on
page 5-7 .
• Module number—The module or slot number on the switch that is always 0.
•
Port number—The interface number on the switch. The 10/100/1000 port numbers always begin
at 1, starting with the far left port when facing the front of the switch, for example,
gigabitethernet1/0/1 or gigabitethernet1/0/8.
On a switch with 10/100/1000 ports and Cisco TwinGig Converter Modules in the 10-Gigabit
Ethernet module slots, the port numbers restart with the 10-Gigabit Ethernet ports:
tengigabitethernet1/0/1.
On a switch with 10/100/1000 ports and Cisco dual SFP X2 converter modules in the 10-Gigabit
Ethernet module slots, the SFP module ports are numbered consecutively following the 10/100/1000
interfaces. For example, if the switch has 24 10/100/1000 ports, the SFP module ports are
gigabitethernet1/0/25 through gigabitethernet1/0/28.
You can identify physical interfaces by physically checking the interface location on the switch. You can
also use the
show privileged EXEC commands to display information about a specific interface or all
the interfaces on the switch. The remainder of this chapter primarily provides physical interface
configuration procedures.
These are examples of how to identify interfaces on a Catalyst 3750-E switch:
• To configure 10/100/1000 port 4 on a standalone switch, enter this command:
Switch(config)# interface gigabitethernet1/0/4
•
To configure 10-Gigabit Ethernet port 1 on a standalone switch, enter this command:
Switch(config)# interface tengigabitethernet1/0/1
• To configure 10-Gigabit Ethernet port on stack member 3, enter this command:
Switch(config)# interface tengigabitethernet3/0/1
If the switch has SFP modules, the port numbers continue consecutively.To configure the first SFP
module port on stack member 1 with 16 10/100/1000 ports, enter this command:
Switch(config)# interface gigabitethernet1/0/25
Procedures for Configuring Interfaces
These general instructions apply to all interface configuration processes.
Step 1
Enter the configure terminal command at the privileged EXEC prompt:
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#
