For example, the partial configuration shown in Example 18-1 configures the interfaces to handle routing for VLANs 1–4.Įxample 18-1 Using the MSM Interfaces as Unique Router Ports interface GigabitEthernet0/0/0 Using each of the Gigabit Ethernet interfaces as a separate router port is the simplest of the two configuration types. The MSM requires a coordinated configuration on both the Catalyst 6000 Supervisor and the MSM itself. The Supervisor configuration is used to assign the MSM interfaces to VLANs or to an EtherChannel bundle, whereas the MSM configuration is used to actually configure the routing process. One important point to note is that both options require that configuration commands be entered on both the Layer 2 Supervisor and the Layer 3 MSM. Grouping all four of the Gigabit Ethernet interfaces into a single EtherChannel bundle.Using each of the Ethernet interfaces as a separate router port.The MSM supports two primary types of inter-VLAN router configurations: Figure 18-1 illustrates the Catalyst 6000 backplane connections.įigure 18-1. Note that 2/0/0 is not used and that these numbers do not refer to the slot where the MSM is installed (they are always locally significant).
These interfaces are labeled as GigabitEthernet 0/0/0, 1/0/0, 3/0/0, and 4/0/0. The MSM contains a faster CPU that is currently used in the 8510.įrom a configuration standpoint, the MSM connects to the Catalyst 6000 backplane via four Gigabit Ethernet interfaces. Therefore, the MSM brings the power of the 8510 to the Catalyst 6000 family (namely IP and IPX routing at approximately 5 million packets per second ). Based on Catalyst 8510 technology, the MSM provides a router-on-a-stick configuration integrated into the Catalyst 6000 chassis. The initial Layer 3 switching engine for the Catalyst 6000 family consisted of the Multi-layer Switch Model (MSM).
