Step 1 From the CWSI Campus map, click two or more MLS devices.
Step 2 Select Reports>Multilayer Switching>Route Processors to display the relationship between Layer 3 route processing devices in your network.
Step 3 Select Reports>Multilayer Switching>Switch Engines to display the relationship between Layer 3 switching and forwarding devices in your network.
For assistance interpreting these reports, see "Interpreting MLS Reports".
Use the MLS reports to display the relationship among MLS devices in your network.
This column lists the Multilayer Switching-Route Processors that are participating in Multilayer Switching (MLS). The Route Processors are listed by either IP address or DNS host name.
This column lists the Multilayer Switching Engines that are performing Layer 3 switching for the routers listed in the MLS Routers field. The Switching Engines are listed by either IP address or DNS host name.
This column lists the Switching Engines that are performing Layer 3 switching (MLS) for the routers listed in the MLS Routers field. The Switching Engines are listed by either IP address or DNS host name.
This column lists the Route Processors that are participating in MLS. The Route Processors are listed by either IP address or DNS host name.
Layer 3 protocols, such as IP and Internetwork Packet Exchange (IPX), are connectionless; they deliver each packet independently of each other. However, actual network traffic consists of many end-to-end conversations, or flows, between users or applications.
A flow is a unidirectional sequence of packets between a particular source and destination that share the same protocol and transport-layer information. Communication from a client to a server and from the server to the client are separate flows. For example, Hypertext Transfer Protocol (HTTP) Web packets from a particular source to a particular destination are a separate flow from File Transfer Protocol (FTP) file transfer packets between the same pair of hosts.
Flows can be based on only Layer 3 addresses. This feature allows IP traffic from multiple users or applications to a particular destination to be carried on a single flow if only the destination IP address is used to identify a flow.
A flow mask determines how a flow will be Layer 3 switched. MLS is performed by using one of three flow mask modes. The mode is based on the access lists on the routers that are being Layer 3 switched.
The flow mask is received by the Switching Engine for each Route Processor for which the Switching Engine is performing Layer 3 switching. A Switching Engine supports only one flow mask (the most specific one) for all Route Processors that are Layer 3 switched. If the Switching Engine detects different flow masks from different Route Processors for which it is performing Layer 3 switching, it changes its flow mask to the most specific flow mask detected.
The different flow masks include (from least specific):
