Theses are very different products. The NME one are a full switch with all the functionalities of an external switch. One notable difference is the number of supported VLANs : depending of the supporting router, 16 to 64 for the NM-16ESW and 1024 for the NME. The NME-16ESW-1G is in fact like a 3750 embedded into the router. You should look at these Q&A for the 2800 series : http://www.cisco.com/en/US/prod/collateral/routers/ps259/prod_qas0900aecd802a9470_ps5854_Products_Q_and_A_Item.html For the 2900/3900 series, it seams to be also enhanced modules that are like 2960 (ES2) and 3960E (ES3) switches : http://www.cisco.com/en/US/prod/collateral/routers/ps10536/qa_c67_554789.html Best regards, -- Alain RICHARD <mailto:[email protected]> EQUATION SA <http://www.equation.fr/> Tel : +33 477 79 48 00 Fax : +33 477 79 48 01 E-Liance, Opérateur des entreprises et collectivités, Liaisons Fibre optique, SDSL et ADSL <http://www.e-liance.fr> _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
