[c-nsp] HWIC-4ESW

[Peter Chuba]

Thank you Nic and all the others who threw some light on the issue. I would
have loved using the HWIC-1FE but I'm in Cameroon and have searched
everywhere for it without success. Getting it shipped in might cost as much
as buying a new router. Anyway, thank you guys for the information.

Peter

Cisco says:
Q. Can I assign each switch port to a unique VLAN? If so, are there
any limitations?
A. Each switch port can be assigned to its own VLAN, effectively
providing four additional routed ports. However, there are serious
performance and feature limitations to doing this. The VLAN interfaces
are truly Layer 3 switching interfaces and are treated uniquely among
interface types on the router. Many features are not supported or
tested on these interfaces, including Point-to-Point Protocol over
Ethernet (PPPOE) termination, Layer 2 Tunneling Protocol Version 3
(L2TPv3) termination, MAC address assignment, Layer 3 QoS, and others.
You should carefully test any desired feature and solution prior to
deploying it.

Is this something that will be used in a production environment? If
thats the case, then its probably not a good idea..
