I have a 3845 with a 4 port hwic installed with 2 vlans running to a switch downstream . They are adding a new "gig" hwic to this 3845 and adding a new Cat 4500 below this . Will I be able to trunk the existing vlans to the new switch or are those restricted to that 4 port fast ether hwic ? I'm guessing no you can;t do that because its not part of that little 4 port switch . Under a tight schedule thats why I am asking here versus trying to set it up in the lab.
Glen, thanks for providing the part number and you are correct. This particular HWIC will behave like a regular routed port that comes with the router. You need to look into the HWIC EtherSwitch family for trunking support without using subinterfaces.
