I have (2) 6509's with FWSM's in slot 9. I need to upgrade the code tonight since the FTP process does not function since there is a bug in the current code. Whe is the procedure to upgrade the code from 2.3.4 to , what is the potential outage time? Also the FWSM's are in an active standby state not active/acative.

Thank you,

You could use TFTP Client on the FWSM for upgrade

copy tftp: flas:image (use it from system space if running in multiple mode)

You can upgrade without outage give minor version difference

a) Make sure the state sync is on

b) Upgrade the Standby

c) Reboot the standby using failover reload standby

d) After standby comes up and does state sync upgrade active and make standby active using "failover active"

e) reload previous active (current standby) using failover reload-standby

Step 1 Make the new software image available on a TFTP server, or make the MSFC a TFTP server by using this command:

msfc(config)# tftp-server bootflash:image name

Step 2 If the MSFC is the TFTP server, make sure you have a VLAN interface on the MSFC reachable from the module. For example:

a. On the MSFC, enter these commands:

router(config)# interface Vlan30

router(config)# description to_fwsm_vlan_30

router(config)# ip address

router(config)# no ip redirects

b. On the module, enter these commands:

nameif vlan30 inside security100


ip address inside

c. From the module make sure that you can ping the MSFC, by entering this command:

FWSM# ping response received -- 0ms response received -- 0ms response received -- 0ms

Step 3 From the module enter the copy tftp flash command:

FWSM# copy tftp flash

Address or name of remote host []?

Source file name [cdisk]? c6svc-fwm-k9.1-1-0-207.bin

copying tftp:// to flash:image



The output shows the MSFC as the TFTP server.

Step 4 Reload the module by entering this command:

FWSM# reload

Proceed with reload? [confirm]
