OSM's have a whole processor on board that needs IOS software loaded; PXF stuff, etc. Some of this is in the bootflash for the OSM, but some (or even most) is loaded from the IOS image. I'm assuming FlexWAN is similar, but I don't have a FlexWAN to try with. Also, there are protocols that are only used for WAN, things like APS and such. And you can't trust Feature Navigator to tell you; try comparing the images for 12.2(18)SXF16 on a 7600 Sup2MSFC2 versus the same IOS on a Catalyst 6500 Sup2MSFC2 (same sup/msfc, should have same features, no?) to see what I mean. Here's a 'show ver' and some other informative commands run from an OSM console showing the special IOS running on the OSM's processor, the location of the PXF microcode, and the differences in the system: filesystem seen from the RP and the CWAN proc: dc-7609-1# attach 3 Entering CONSOLE for slot 3 Type "^C^C^C" to end this session CWTLC-Slot3>enable CWTLC-Slot3#sh ver Cisco Internetwork Operating System Software IOS (tm) cwtlc Software (cwtlc-DW-M), Version 12.2(18)SXF16, RELEASE SOFTWARE (fc2) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2009 by cisco Systems, Inc.
