Upgrading Cisco IDS Software from Version 4.0 to 4.1

The IDS-4210 sensor must be upgraded to 512MB of memory in order to upgrade the sensor to software version 4.1 requirements. This requires an additional 256MB of memory that can be purchased from Cisco. Customers with a current SmartNET contract can request the memory upgrade at no charge.

The IDSM (WS-X6381) cannot be upgraded to Cisco IDS 4.1. The IDSM (WS-X6381) must be replaced with WS-SVC-IDSM2-K9, which supports version 4.x software.
