Hello @SimonLI08960 ,

a SW based router like the C3825 is not really capable of multi gigabit performance , I think this is the reason why an NM-2GE module does not exist.

However, you can use Vlan based subinterfaces as a way to have more logical interfaces and connect one GE to a switch port configured as a trunk  allowing the Vlans.

This can provide you additional logical interfaces.

 

Hope to help

As already noted by Giuseppe, the 3825, although it has gig ports, isn't really suitable to support even a single gig port at (sustained) full speed. It's only rated at 385 Kpps for minimum size Ethernet (about 179 Mbps) without advanced features being used.

Can it deliver higher rates? With larger packets it can.
