Upgrading Cisco IPS Software to 5.0
Note
You cannot upgrade the IDSM (WS-X6381) to Cisco IDS 5.0. You must replace your IDSM
(WS-X6381) with IDSM-2 (WS-SVC-IDSM2-K9), which supports version 5.0.
The minimum required version for upgrading to 5.0 is 4.1(1). The upgrade from Cisco 4.1 to 5.0 is
available as a download from Cisco.com. For the procedure for accessing Downloads on Cisco.com, see
Obtaining Cisco IPS Software, page 18-1
.
After downloading the 5.0 upgrade file, refer to the accompanying Readme for the procedure for
installing the 5.0 upgrade file using the
upgrade
command. Or see
Upgrading the Sensor, page 17-2
.
If you configured Auto Update for your sensor, copy the 5.0 upgrade file to the directory on the server
that your sensor polls for updates. For the procedure, see
Configuring Automatic Upgrades, page 17-5
.
If you install an upgrade on your sensor and the sensor is unusable after it reboots, you must reimage
your sensor. Upgrading a sensor from any Cisco IDS version before 4.1 also requires you to use the
recover
command or the recovery/upgrade CD.
You can reimage your sensor in the following ways:
•
For IDS appliances with a CD-ROM drive, use the recovery/upgrade CD.
For the procedure, see
Using the Recovery/Upgrade CD, page 17-18
.
•
For all sensors, use the
recover
command.
For the procedure, see
Recovering the Application Partition, page 17-9
.
•
For the IDS-4215, IPS-4240, and IPS 4255, use the ROMMON to restore the system image.
For the procedures, see
Installing the IDS-4215 System Image, page 17-11
, and
Installing the
IPS-4240 and IPS-4255 System Image, page 17-15
.
•
For NM-CIDS, use the bootloader.
For the procedure, see
Installing the NM-CIDS System Image, page 17-19
.
