Guys

Modules for Wism,FWSM,WLC,ACE goes without interfaces on it,so how the connectivity happened?

Thanks

For example the FWSM does not include any external physical interfaces. Instead, it uses VLAN interfaces. Assigning VLANs to the FWSM is similar to assigning a VLAN to a switch port; the FWSM includes an internal interface to the Switch Fabric Module (if present) or the shared bus.

Likewise the ACE modules uses internal vlan interfaces.

Thanks Fransisco,what is the role of the backplane here in this situation

[francisco_1]

The FWSM  uses the backplane of the switch to get connect to the network with a 5Gbps uplink to the backplane, which is potentially a lot better than the 1Gbps on a physical interface.
