Cisco Cisco Token Ring Port Adapters 설치 가이드

To load the microcode from an individual microcode image that is stored as a file on a Flash memory 
card, enter the microcode command, the port adapter type, the specific memory location of the PCPA 
microcode image, and the exact argument for filename (xcpa26-4 is used in this example): 

Router(config)# microcode pcpa slot0:xcpa26-4 

Router(config)# microcode reload 

The microcode reload command is written automatically in the configuration 
file following the microcode pcpa command when you modify the system 
default to load a microcode image.

The no microcode command cancels any existing instructions to load an image from a Flash memory 
card and restores the default configuration:

Router(config)# no microcode pcpa slot0:xcpa26-4 

To save the configuration file, press Ctrl-Z (or type end), then copy the new configuration to NVRAM:

Router# copy running-config startup-config

To verify that the correct microcode is loaded according to the new instructions, enter the show 
controllers EXEC command. The display indicates the currently loaded and running microcode 
version for the PCPA. 

To verify the contents of the configuration file, enter the show running-config EXEC command. You 
can also verify that the correct software image is configured to load at system restart or reload by using 
the show startup-config EXEC command. 

The following provides information on the different functions of Flash memory that you might need 
when configuring microcode:

Copying a new image to a Flash memory card might be required when a new microcode image becomes 
available. Use the command copy tftp:filename [ bootflash | slot0 | slot1 ]:filename for the copy 
procedure, where tftp:filename is the source of the file and [ bootflash | slot0 | slot1 ]:filename is the 
destination in onboard Flash memory or on either of the Flash memory cards. The following example 
shows the output from the copy tftp:filename command: 

Router# copy tftp:xcpa26-4 slot0:xcpa26-4
