Configuring Automatic Upgrades

If you get an unauthorized error message while configuring an automatic update, make sure you have the

correct ports open on any firewalls between the sensor and Cisco.com. For example, you need port 443

for the initial automatic update connection to www.cisco.com, and you need port 80 to download the

chosen package from a Cisco file server. The IP address may change for the Cisco file server, but you

can find it in the lastDownloadAttempt section in the output of the show statistics host command.

Caution In IPS 7.1(5)E4 and later the default value of the Cisco server IP address has been changed from

198.133.219.25 to 72.163.4.161 in the Auto Update URL configuration. If you have automatic update

configured on your sensor, you may need to update firewall rules to allow the sensor to connect to this

new IP address.

Note To check the status of the last automatic update or the next scheduled automatic update, run the show

statistics host command and check the Auto Update Statistics section.

To schedule automatic upgrades, follow these steps:

Step 1 Log in to the CLI using an account with administrator privileges.

Step 2 Enter automatic upgrade submode.
