interface-vlan versus no-switchport on L3 switch

[jimmyc_2]

We currently use routable 4507s. We connect to other routers using the interface-vlan IP addresses. I am about to clean up the configuration by assigning ports as "no switchport", then putting the IP address on those physical ports. Is this wise, or even desirable? Is there an advantage either way? Thanks

I am not very familiar with c4500 but with c3750.

So i belive you will lose some nice features with L3 Interfaces. With L3 Interfaces you can not build sub-interfaces and you do not have the choice to switch one VLAN and route other VLAN`s using the same physical Interface. Also VRF-Lite makes more sense via switched ports.

Only in high security environments L3 ports are better, cause all L2 packets are terminated.

But switching from L3 interface to svi or vice versa should be possible in nearly every environment to match your network requirements.
