Release Notes for Cisco Router and Security Device Manager 2.5
OL-5009-20
Important Notes
Step 4 At the prompt, enter the enable command, and enter the password cisco.
yourname> enable
Password: cisco
yourname#
Step 5 Enter the erase startup-config command.
yourname# erase startup-config
Step 6 Confirm the command by pressing Enter.
Step 7 Enter the reload command.
yourname# reload
Step 8 Confirm the command by pressing Enter.
After the router completes the reload operation, it enters into the standard Cisco IOS startup sequence.
You can use the startup sequence to give the router a configuration manually, or to copy a configuration
file from the network. If you later decide you want to use Cisco SDM to change an existing
configuration, see the instructions on starting Cisco SDM included in the quick start guide for the router.
Unable to Perform “squeeze flash:” Operation
If the router is using a Cisco IOS image earlier than release 12.3T, or release 12.2(13)ZH, it may be
necessary to use the squeeze flash: command to reclaim flash memory after repeated use of Cisco SDM.
If this becomes necessary, Cisco SDM informs you that the squeeze flash: command must be used, and
will execute the command upon your confirmation.
However, the squeeze flash: command will not work if an erase flash: command has never been
executed on the router. If this is the case you will receive an “Unable to perform ‘squeeze flash’” warning
message, and you will need to run the erase flash: command to enable the use of the squeeze flash:
command.
Executing the erase flash: command removes Cisco SDM and the Cisco IOS image from the router flash
memory, and you will lose your connection to the router. Complete the following steps to save files in
flash memory, execute erase flash:, and copy the files back so you can reconnect to Cisco SDM.
Step 1 Ensure that the router will not lose power. If the router loses power after an erase flash: operation, there
will be no Cisco IOS image in memory.
Step 2 Prepare a TFTP server to which you can save files and copy them over to the router. You must have write
access to the TFTP server. Your PC can be used for this purpose if it has a TFTP server program.
Step 3 Open up a Telnet session on the router so that you can use the CLI.
Step 4 Save the router’s running configuration to the startup configuration by entering the command
copy running-config startup-config.
Step 5 Use the copy tftp command to copy the Cisco IOS image, and the Cisco SDM files from flash memory
to a TFTP server:
copy flash: filename tftp://tftp-server-address/filename
For example:
Router# copy flash: sdm.tar tftp://10.10.10.3/sdm.tar
