WAN Routing Question HWIC Cards

Unanswered Question

We connect our branches with Cisco 1841 ISR routers by using VLANS on 4 port HWIC cards. It seems to me that we should be using the local ethernet ports on the router to route the WAN traffic and not the HWIC ports. If this is the case, are there expansion cards out there to give me extra local ethernet layer 3 ports?

Yes, the HWIC-1FE and HWIC-2FE. I do not understand however why do you need these.

We have multiple sites that have four WAN connections coming into the site. For example our wireless tower locations that are a hub for a number of locations. Currently we have four wireless connections hooked to a 4 Port HWIC card using VLANs. Is there a better way. I believe there is, but I don't know what it is.

Actually if your current setup works fine, you should not worry about it.


One should know a lot more details about your setup to suggest an alternative.

It does work, but it seems like it could work better for us. I guess we are always looking to get the most. Thanks for the card suggestions.

You should define what means "work better" to you. In networking, we use precise definition when possible.
