IDS memory requirements to 4210 IDS signature upgrades

[sguerrero]

I have IDS 4210, show version appears like this:

IDS# sh ver

Application Partition:

Cisco Systems Intrusion Detection Sensor, Version 4.0(1)S37

OS Version 2.4.18-5smpbigphys

Platform: IDS-4210

Using 257458176 out of 261312512 bytes of available memory (98% usage)

Using 1.1G out of 17G bytes of available disk space (7% usage)

I want to upgrade this IDS to IDS-sig-4.1-4-S100.rpm.pkg, but readme says first I have to upgrade to Version 4.1(1)S47 to 4.1(3)S61 sensors must first be updated with the 4.1(4)S91 Service Pack before applying the 4.1(4)S100 Signature Update.

Reviewing information, In order to update to version 4.1(1)S47, documentation also says IDS-4210 and IDS-4220 series sensors must be upgraded to 512 MB RAM using a Cisco upgrade kit (Part # IDS-4210-MEM-U or IDS-4220-MEM-U) before they can be upgraded with IDS software version 4.1 or later. This upgrade is free to customers with SMARTnet.

Please let me know if according to my show version I already have the memory requirements.

Thanks for any help,

To upgrade to 4.1-4-S100 you only need to first upgrade to minor update version 4.1(1)S47 from 4.0(1)S37, followed by service pack 4.1(4)S91. You don't have to apply 4.1(2) and 4.1(3) before applying 4.1(4), as 4.1(4) is a cumulative service pack.

From your show version, it looks like you haven't upgraded to the required 512 MB ram. Once you upgrade to the 512MB the show version should show something like

Using 452706304 out of 509276160 bytes of available memory (88% usage)

Hope this helps
