I currently have a Cisco 2851 router running the following IOS
C2800NM-ADVIPSERVICESK9-M), Version 12.4(9)T
We have two additional HWIC-4ESW cards installed in the 2851 router.
The first card works ok as a layer 2 and 3 but the second card only works as a layer two device.
Can I replace the 2 HWIC-4ESW cards with a HWIC-9-D-ESW card and can all 9 ports used with different VLAN's and at layer 3?
