Chapter7 Configuring Interface Cha racteristics
Using the Interface Command
Ethernet ports), the port number restarts with the second interface type: gigabitethernet0/1,
gigabitethernet0/2. The interface notation for switch ports 1 to 20 is interface gigabitethernet
(such as interface gi).
Switch ports 1 to 14 are internal 1000 Mbps connections to the other blades in the BladeCenter.
These ports operate at 1000 Mbps in full-duplex mode.
Switch ports 15 and 16 are internal 100 Mbps connections to the Management Module . These ports
operate at 100 Mbps in full-duplex mode.
Note You cannot change the speed and duplex settings on the internal ports 1 to 16.
Switch ports 17 to 20 are for connections to external devices such as other switches. Depending on
the switch model, you can change the speed and duplex settings on the external ports 17 to 20.
You can identify physical interfaces by physically checking the interface location on the switch. You
can also use the Cisco IOS show privileged EXEC commands to display information about a specific
interface or all the interfaces on the switch. The re mainder of this chapter primarily provides physical
interface configuration procedures.
This section describes how to configure all types of interfaces and how to configure a range of interfaces:
•Procedures for Configuring Interfaces, page 7-5
•Configuring a Range of Interfaces, page 7-6
•Configuring and Using Interface-Range Macros, page 7-7
Procedures for Configuring Interfaces
These general instructions apply to all interface configuration processes.
Step1 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)#
Step2 Enter the interface global configuration command. Identify the inte rface type and the number of the
connector. In this example, Gigabit Ethernet interface 0/17 is selected:
Switch(config)# interface gigabitethernet0/17
Switch(config-if)#
Note You do not need to add a space between the interface type and interface number. For example,
in the preceding line, you can specify either gigabitethernet 0/1, gigabitethernet0/1, gi 0/1, or
gi0/1.
