Routed ports and EHWIC-D-8ESG-P

[dpita3186]

Hello,

We have a 2921 with a EHWIC-D-8ESG-P module for service to a local telecom closet.  The building is being serviced by two switches connected to a gig port with subinterfaces.  Is there a way to use the subinterfaces defined on the gig port on the EHWIC-D-8ESG-P module?

R1#sh ip int bri

Hi dpita,

I don't think you can create subinterfaces on the EHWIC-D-8ESG-P as the ports are layer 2 but an alternative is to create SVIs for each subinterface or subnet and then trunk it to the switch via one or bundle of ports from the EHWIC module.

Hope this helps.

Thanks!

I ended up removing the EHWIC since we needed a fiber link and no one wanted to buy a media converter to use the EHWIC.
