Hello!
We just upgraded our two C4500x Catalyst 4500x-32 SFP+ Switch to version 03.07.03.E.152-3.E3 running in VSL configuration, in hopes of having our GRE tunnels hardware switched.
System image file is "bootflash:cat4500e-universalk9.SPA.03.07.03.E.152-3.E3.bin"
Jawa Revision 2, Winter Revision 0x0.0x41
And the license should allow Hardware GRE tunnel:
License Information for 'WS-C4500X-32'
License Level: entservices Type: Permanent
Next reboot license Level: entservices
Unfortunately we are recieving the following error:
Feb 16 13:58:45.944: %C4K_NOVAFFM-4-L3TUNADJOPTIONSENABLED: 1 ffm: %Warning: Feature not supported in hardware. Tunnel601 packets will be software switched
Feb 16 13:58:45.944: %C4K_NOVAFFM-4-L3TUNADJOPTIONSENABLED: STANDBY:11 ffm: %Warning: Feature not supported in hardware. Tunnel601 packets will be software switched
We are unble to think of what could be causing this error, our guess is that it's "Layer 3 Adjacency Options Enabled" but we are not aware whice options are enabled. The GRE tunnel has an unique source and destination address, and checksum and sequencing is disabled.

This is from one one side of the GRE tunnel, it is set up the same way on the other side of the tunnel.
Does anyone have any ideas as to what is preventing us from hardware switching our GRE Tunnel?
Best regards
