Cisco Systems NPE-225 사용자 설명서

The NPE-G2 requires that you copy and save your running configuration file to a CompactFlash Disk, 
PC Card, or TFTP server before you install the NPE-G2. For instructions on copying and saving your 
configuration file, see the 

 in 

 

 
For general preparation for installation instructions, see 

 For 

installation and configuration instructions specific to the NPE-G2, see 

 

The NPE-G2 software image and kboot image name begins with “c7200p-”, which is different from 
that of previous network processing engines. 

The RJ-45 ports and SFP ports are both reported in software as GigabitEthernet 0/1, GigabitEthernet 
0/2, and GigabitEthernet 0/3. Only one of the pair of interface ports can be used at a time; for 
example, SFP GigabitEthernet 0/2 or RJ-45 GigabitEthernet 0/2.

The I/O controller GE/E interface reports GigabitEthernet 0/0 and Ethernet 0/0, and the I/O 
controller 2FE/E interface reports FastEthernet 0/0 and FastEthernet 0/1.

If the RJ-45 port is in use, the EN (Enable) LED is on. If the SFP port is in use, the EN (Enable) 
LED is off.

With the NPE-G2 and an I/O controller both installed, the I/O controller functionality on the 
NPE-G2 is shared with that of the I/O controller. 

When both an NPE-G2 and an I/O controller are installed, the flash memory and NVRAM of the 
NPE-G2 are enabled and the flash memory 

and NVRAM on the I/O controller are no longer accessible. 

The console and auxiliary ports on the NPE-G2 are disabled by Cisco IOS when an I/O controller is 
present; the console and auxiliary ports on the I/O controller are active.

Console port messages can be routed to the auxiliary port on either the NPE-G2 or on the I/O 
controller.

The default media is the RJ-45 port. To change the media type, use the media-type command.

Only the port selected by the media-type command is active. A cable attached to the other of the 
RJ-45 and SFP module pair will be ignored. For example, if SFP port GigabitEthernet 0/2 is selected 
using the media-type command, RJ-45 GigabitEthernet 0/2 is ignored, even if a cable is attached to 
RJ-45 0/2. 

The NPE-G2 uses no bandwidth points, and when used with any I/O controller, the I/O controller 
also uses no bandwidth points. None of the Gigabit Ethernet interfaces on the NPE-G2 use 
bandwidth points. 

The CompactFlash Disk on the NPE-G2 is available at all times, with or without an I/O controller 
installed. The CompactFlash Disk is always addressed as the disk2 device, to avoid conflicts with 
the disk0 and disk1 devices on the I/O controller, if the I/O controller is also installed. 

USB Flash memory modules are available for data storage, with or without an I/O controller 
installed.
