Cisco Systems 8540 CSR Manual De Usuario

The interface port identifiers on the Ethernet modules remain the same regardless of whether other
modules are installed or removed. However, when you move an interface module to a different slot, the
first number in the address changes to reflect the new slot number.

You can identify module ports by physically checking the slot/subslot/interface location on the back of
the switch router. You can also use Cisco IOS show commands to display information about a specific
interface, or all the interfaces, in the switch router.

The following general configuration instructions apply to all interfaces. Begin in global configuration
mode. To configure an interface, follow these steps:

Use the configure EXEC command at the privileged EXEC prompt to enter the global configuration
mode.

Router> enable

Router# configure terminal

Router (config)#

Enter the interface command, followed by the interface type (for example, Fast Ethernet or Gigabit
Ethernet) and its interface port identifier (see the “Interface Port Identifier” section on page 4-2).

For example, to configure the Gigabit Ethernet port on slot 1, port 1, use this command:

Router(config)# interface gigabitethernet 1/0/1

slot number / subslot number / interface number

 

27934

The slot in which the 
interface module or port 
adapter is installed. 
Slots are numbered 
starting at 0.

The subslot in which the 
interface module or port 
adapter is installed. For a 
full-width interface 
module, this number is 
always 0.

The port or interface 
number on the interface 
module or port adapter. 
Numbering always starts 
at 0 and goes from left to 
right.
