Feature is not shown in cisco feature navigator

[zittastanislav]

Good morning, 

I came to important problem regarding cisco feature navigator. I was looking for particular features (I'd like to implement in near future) in particular Cisco IOS images (I have on my network) and I found out, that cisco feature navigator doesn't show some features as present in some images even though commands for configuration of these features seem available. One such feature is DHCP snooping on c2960x-universalk9-mz.150-2.EX3.bin IOS. If I try to look it up in feature navigator, I see that this particular feature isn't present (please take a look at attached file). When I go into console of particular device with that image, there are commands like:

SW1#show ip dhcp snooping
Switch DHCP snooping is disabled
DHCP snooping is configured on following VLANs:
none
DHCP snooping is operational on following VLANs:
none
DHCP snooping is configured on the following L3 Interfaces:

SW1#show ip dhcp snooping binding
MacAddress          IpAddress        Lease(sec)  Type           VLAN  Interface
------------------  ---------------  ----------  -------------  ----  --------------------
Total number of bindings: 0

available. 

Is it usual that there can be slight discrepancies when comparing reality with cisco feature navigator?

Thank you in advance, 

Standa

Hi Leo, 

thanks for your reply, but I'm afraid we misunderstood each other. My question wasn't related to DHCP snooping configuration as such, It was related to problem, that Cisco feature navigator reports DHCP snooping as unavailable in particular IOS regardless of fact, that particular IOS allows me to enter commands for DHCP snooping configuration. If I had this problem with one particular feature, It would be no problem for me to verify absence or presence of that feature in particular IOS by configuring that feature. But what if I  have ten IOSes and 12 features and I want to know whether these IOSes are able to run these features? It seems as huge burden for me to configure all the features on all the IOSes in order to determine whether they're capable of these features.
