If there is no access to a TFTP server, a USB flash drive could be an alternate way to load the

signature package into Cisco IOS IPS. First, copy the signature package into the USB drive, then

insert the USB flash drive into one of the USB ports on the router. The following message will

show up in the router console:

*Aug 18 06:46:49.554 PST: %USBFLASH-5-CHANGE: usbflash1 has been

inserted!

Now use the copy command to load the signature package from usbflash to Cisco IOS IPS:

training#copy usbflash1:IOS-S261-CLI.pkg idconf

All signatures are by default configured to 'Alarm' action only. If you want to configure additional

actions, the following CLI commands are available to change the signature configurations.

training(config)#ip ips signature-category

training(config-ips-category)#category ios_ips basic

training(config-ips-category-action)#event-action deny-packet-inline

training(config-ips-category-action)#event-action reset-tcp-

connection

training(config-ips-category-action)#exit

training(config-ips-category)#exit

signatures

...

IMPORTANT: Make sure that you accept the changes when prompted. Otherwise, they will not be

saved.

Use the show run command at the router prompt to verify the signature category configuration:

show run

ip ips signature-category

category all

retired true

category ios_ips basic

retired false

event-action deny-packet-inline

event-action reset-tcp-connection
