32 Ethernet Interface Processor (EIP) Installation and Conﬁguration

Upgrading Microcode

Caution Before you copy a ﬁle to Flash, be sure there is ample space available in Flash memory.

Compare the size of the ﬁle you wish to copy to the amount of available Flash memory shown. If the

space available is less than the space required by the ﬁle you wish to copy, the copy process will

continue, but the entire ﬁle will not be copied into Flash.

Follow these steps to copy a microcode version from the TFTP server to Flash memory.

Step 1 To display the total amount of Flash memory present, its location, any ﬁles that currently

exist in Flash memory and their size, and the amount of Flash memory remaining, use the

show ﬂash command. Following is an example of the output that is displayed:

Router# show flash

4096K bytes of flash memory on embedded flash (in RP1).

file offset length name

0 0xD134 55410 sp1-2

[4085336/4194304 bytes free]

Step 2 Compare the amount of available Flash memory (last line in the preceding example) to the

size of the new microcode image on the ﬂoppy disk to ensure that there is sufﬁcient space

available. If you attempt to copy in a new image, and the size of the new image exceeds the

available space in Flash, only part of the new image will be copied, and the following error

message will be displayed:

buffer overflow - xxxx/xxxx

where xxxx/xxxx is the number of bytes read in/number of bytes available.

Step 3 After you verify that there is sufﬁcient space available in Flash memory for the new image,

enter the following command at the privileged-level prompt:

Router# copy tftp flash

Step 4 Enter the IP address of the remote host:

IP address or name of remote host [255.255.255.255]? 131.108.12.106

Step 5 Enter the name of the ﬁle you want to copy to Flash memory (eip1-1 in the following

example):

Name of file to copy ? eip1-1

Step 6 To conﬁrm that you want the ﬁle copied into Flash, press Return.

Copy eip1-1 from 131.108.12.106 into flash memory? [confirm]

If the correct ﬁle is not shown, enter no to return to the system prompt and enter the correct

ﬁle name.
