The routers where running IOS 12.4(3c) ip base so i upgraded to 12.4(21)ip base as instructed. The routers still dont recognise the modules. The cisco data sheet says the routers need IOS 12.4(11)T or above and IP base image or above. If i do show inventory i get NAME: "unknown", DESCR: "unknown" PID: NME-NAC-K9.</P><P></P><P>Do i need a different IOS image on the routers to activate the modules?</P><P></P><P></P><P>Thanks</P> Fri, 21 Feb 2020 11:02:16 GMT c01642643287 2020-02-21T11:02:16Z NAC Module and Router IOS version https://community.cisco.com/t5/network-security/nac-module-and-router-ios-version/m-p/1118867#M775020 <P>Hi</P><P></P><P>I have recently purchased two NAC modules for our 3845 ISR's.
