Procedures For Configuring Interfaces - Cisco WS-C3020 Software Configuration Manual

Using Interface Configuration Mode
•
•
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.

Procedures for Configuring Interfaces

These general instructions apply to all interface configuration processes.
Enter the configure terminal command at the privileged EXEC prompt:
Step 1
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#
Enter the interface global configuration command. Identify the interface type and the number of the
Step 2
connector. In this example, Gigabit Ethernet port 1 is selected:
Switch(config)# interface gigabitethernet0/1
Switch(config-if)#
Note
Step 3 Follow each interface command with the interface configuration commands that the interface requires.
The commands that you enter define the protocols and applications that will run on the interface. The
commands are collected and applied to the interface when you enter another interface command or enter
end to return to privileged EXEC mode.
You can also configure a range of interfaces by using the interface range or interface range macro
global configuration commands. Interfaces configured in a range must be the same type and must be
configured with the same feature options.
After you configure an interface, verify its status by using the show privileged EXEC commands listed
Step 4
in the
Enter the show interfaces privileged EXEC command to see a list of all interfaces on or configured for
the switch. A report is provided for each interface that the device supports or for the specified interface.
Cisco Catalyst Blade Switch 3020 for HP Software Configuration Guide
9-8
Module number—The module or slot number on the switch (always 0 on the Cisco Catalyst Blade
Switch 3020for HP).
Port number— the interface number on the switch. The port numbers always begin at 1, starting with
the internal blade server-facing interfaces. The external interfaces on the front panel of the switch
start at 17. The SFP module ports are numbered left to right. The external RJ-45 ports are numbered
from top to bottom and from left to right. The first RJ-45 port, 17, is on the top left. RJ-45 port 18
is on the bottom left.
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.
