Catalyst 5000 series switches support the Route Switch Module (RSM) and the RSM/Versatile Interface Processor 2 (VIP2). This chapter describes the RSM and is divided into the following sections:
For detailed RSM installation and configuration information, refer to the Catalyst 5000 Series Route Switch Module Installation and Configuration Note. For detailed RSM/VIP2 installation and configuration information, refer to the Route Switch Module Catalyst VIP2-15 and VIP2-40 Installation and Configuration Note.
This section describes the RSM, its LEDs, and its features.
The RSM is a router module running Cisco IOS router software that plugs directly into the Catalyst 5000 series switch backplane, providing multiprotocol routing for the Catalyst 5000 series Ethernet interfaces.
From the perspective of the Catalyst 5000 series switches, the RSM appears as a module with a single trunked port and one Media Access Control (MAC) address. From the perspective of the user, the RSM has one port. This port is unlike other Catalyst 5000 series module ports in that it has no external attributes, such as media type or speed.
Figure 7-1 shows the RSM front panel.
The RSM front panel has the following features:
The RSM requires Catalyst 5000 series supervisor engine module software release 2.3(1) or greater and Cisco IOS software release 11.2(7)P or greater.
The RSM LEDs, shown in Figure 7-2, are described in Table 7-1.
| LED | Description |
|---|---|
| STATUS | The switch performs a series of self-tests and diagnostic tests. If all the tests pass, the LED is green. If a module reset is in progress or the module failed power-on diagnostics, the LED is red. If the module is disabled, the LED is orange. If self-test diagnostics are running on the module, the LED is orange. If a system boot is in progress, the LED is orange. |
| CPU HALT | This LED indicates RSM status. During normal operation, the CPU HALT LED is on. The CPU HALT LED goes off if the system detects a processor hardware failure. |
| ENABLED | This LED is on when the IP microcode is loaded and the RSM is operational. |
| PCMCIA SLOT 0 and SLOT 1 | These LEDs light when their respective slot 1 and slot 0 PCMCIA devices are accessed by the RSM. See the "Using Flash Memory (PCMCIA) Cards" section of the Catalyst 5000 Series Switch Route Switch Module Installation and Configuration Note for detailed information. |
| TX (Transmit) | When a port is transmitting a packet, the LED is green; otherwise it is off. |
| RX (Receive) | When a port is receiving a packet, the LED is green; otherwise it is off. |
The RSM provides multiprotocol routing for the Catalyst 5000 series switch Ethernet interfaces. Table 7-2 lists the Cisco IOS features available for the RSM.

This section describes the RSM/VIP2 module combination.
You can use the RSM as a standalone interVLAN router or you can enhance it by adding a Catalyst VIP2 module to provide direct external network connections through a variety of media with the same port adapters used on Cisco 7500 series routers. The RSM/VIP2 combination provides routing between Catalyst VIP2 port adapters, and between VLANs and Catalyst VIP2 port adapters. The Catalyst VIP2 module supports any combination of available Catalyst VIP2 port adapter-based network interface types. When you use the RSM with the Catalyst VIP2 module, the combination is a double-wide module that occupies two consecutive slots in the chassis.
Figure 7-3 shows a Catalyst VIP2 module with a port adapter installed.
The current Catalyst VIP2 products have the following dynamic random-access memory (DRAM) and static random-access memory (SRAM) configurations:
The Catalyst VIP2 central processing unit (CPU) is a Reduced Instruction Set Computer (RISC), Mips 4700 processor, with an internal operating frequency of 100 MHz and a 50-MHz system bus interface. The Catalyst VIP2 module has a 128-KB nonvolatile random-access memory (NVRAM).
The Catalyst VIP2-15 upgrade option (Catalyst VIP215/40-UPG=) allows you to upgrade to 2-MB SRAM and 32-MB DRAM.
Software licenses are included to use Distributed Switching and Distributed Services.
The port adapters attach to the Catalyst VIP2 motherboard (see Figure 7-3). Each port adapter contains the physical connections for the Catalyst VIP2 interface types to connect to your network. For the available electrical interface supported by the Catalyst VIP2 module, refer to the Cisco Products Catalog.
 Caution
| Catalyst VIP2 modules with a single port adapter must have a blank port adapter installed to maintain compliance with electromagnetic interference (EMI) emissions standards and chassis airflow requirements. Each port adapter has one Phillips-head screw that secures it to its port adapter slot. |
For detailed information on installing and configuring the RSM/VIP2 modules, refer to the Route Switch Module Catalyst VIP2-15 and VIP2-40 Installation and Configuration Note.
