Route Switch Module (RSM), Route Switch Feature Card (RSFC), or external Cisco 7500, 7200, 4700, 4500, or 3600 series routerĬisco IOS® Software Release 11.3(2)WA4(4) or later on the RSM, or on Cisco 7500, 7200, 4700, and 4500 series routersĬisco IOS Software Release 12.0(3c)W5(8a) or later on the RSFCĬisco IOS Software Release 12.0(2) or later on Cisco 3600 series routersĬisco IOS Software Release 12.0(3c)W5(8) or later on the MLS-RP, if running MLS over ATM media They do not support external MLS (MLS-RP). Note: The Catalyst 65 MSFC2 with PFC2 (Supervisor Engine 2) and Supervisor Engine 720 with MSFC3 perform 元 switching using Cisco Express Forwarding (CEF) and do not require MLS internally. The Catalyst 65 do not support external MLS (MLS-RP). No MLS configuration is required on the Supervisor Command Language Interpreter (CLI) or the routing module. MLS is enabled by default internally between the Supervisor module and MSFC. MLS is supported on all Catalyst 65 switches with Supervisor Engine 1 or 1A using the MultiLayer Switch Feature Card (MSFC) or MSFC2. If running MLS over ATM media, Catalyst 5000 family ATM module software release 11.3(8)WA4(11) or later, or release 12.0(3c)W5(10) or later The information in this document is based on these software and hardware versions:Ĭatalyst 5000 family switch with Supervisor Engine II G or III G, or Supervisor Engine III or III F with a NetFlow Feature Card (NFFC) or NFFC II There are no specific requirements for this document. Internetwork Packet Exchange (IPX) MLS and Multicast MLS are beyond the scope of this document. MultiLayer Switching (MLS) is Ethernet-based routing switch technology by Cisco that provides Layer 3 (元) switching in conjunction with existing routers.
