I'd guess that's not what's causing you the connectivity problems.

I only have a limited knowledge of Cisco systems, but from what I know the max VLANs are the actual maximum number of VLANs that you can configure. Where as VLAN ID's is a feature that can be used to group VLANs. See:

Many thanks,

what's the difference between these 2 values?

Max VLANs -1K

VLAN IDs - 4K

also any idea how many SVIs are processing in asic as opposed to hardware

thanks in advance

Does this help?

"Table 2. Cisco Catalyst 3560 v2 Series Switch Hardware

Max VLANs -1K

VLAN IDs - 4K

Switched Virtual Interfaces (SVIs) - Up to 1000"

Couldn't find anything on differences between IP Services and IP Base yet.

I don't know if I have understood your question correctly, but the following page seems to suggest a maximum of 1000 VLANs and up to 1000 SVIs:
