Cisco Router Etherswitch Module Differences

[jkir]

Hi,

I'm trying to find out what features/limitations/differences exist between the Cisco Etherswitch Service Modules (eg: NME-16ES) and the Cisco EtherSwitch HWIC (eg: HWIC-D-9ESW).
Obviously the number of ports and the module types are different but what else differs?

I want to be able to put one of them into a 2851 router (IP Base) and use GLBP, NetFlow, NBAR and possibly even BGP at some point.

I know the router can do all of those things, I just need to know if choosing either of the above modules would affect what I can implement.

Thanks

JK

I'm just now learning how to deal with an NME-X-23ES-1G in a 2821 router. One thing I found confusing was that, in order to access the switch engine via the backplane I had to assign an IP address to the backplane interface - but that address could NOT be in the same subnet as the main gigabit interface.

I'm not sure how you access the HWIC (meaning it shows up as a directly-addressable set of interfaces); the NME shows up as aa single Gig interface to the router's IOS, and the FA interfaces of the NME are only accessible from the switch engine interface. The NME FA interfaces are not part of the IOS config.

Hope that made sense......
