Fabric Integration Modules

The Catalyst 5500 switch supports two types of fabric integration modules. This chapter describes the fabric integration modules and consists of these sections:

For specifications on the fabric integration modules, see Appendix A, "Specifications."

For information on installing fabric integration modules, refer to Chapter 3, "Switching Module Installation."

For information on configuring fabric integration modules, refer to the Software Configuration Guide for your switch.

Catalyst 5500 Layer 3-Fabric Integration Module (WS-X5305)

The Layer 3-fabric integration module seamlessly integrates the Catalyst 5500 switching fabric and the Catalyst 8510 campus switch router (CSR) switching fabric in a Catalyst 5500 chassis.

The module, shown in Figure 10-1, consists of eight external 100BaseFX Fast Ethernet ports and four 100-Mbps internal interfaces that integrate the Catalyst 5500 switching backplane to the Catalyst 8510 CSR switching backplane. The module can be installed in slots 9 through 12 in the Catalyst 5500 switch to bridge the two backplanes.

Figure 10-1: Layer 3-Fabric Integration Module (WS-X5305)

The eight external Fast Ethernet ports (SC connectors) function exactly as any other Catalyst 5000 family 100BaseFX Fast Ethernet MMF ports. When the fabric integration module is installed in slots 9 through 12 of the Catalyst 5500 chassis, these eight ports function normally regardless of whether there is a Catalyst 8510 CSR switch route processor (SRP) installed in slot 13.

By default, the four internal interfaces are configured as a Fast EtherChannel Inter-Switch Link (ISL) VLAN trunk that provides an 800-Mbps (400-Mbps full-duplex) link between the Catalyst 5500 switch and the Catalyst 8510 CSR switch.

To achieve connectivity between the two switches, you must configure a port-channel interface on the Catalyst 8510 CSR switch and group the four internal interfaces to that port-channel interface. You must then configure subinterfaces on the port-channel interface. Configure a subinterface for each VLAN configured on the Catalyst 5500 switch. For each subinterface, you must specify ISL encapsulation and assign an IP address and subnet mask.

Frames originating on the Catalyst 5500 switch backplane are forwarded across the trunk link to the subinterfaces that you configure. Traffic is routed between VLANs (subinterfaces) as appropriate. Frames originating on the Catalyst 8510 CSR are forwarded across the trunk link to the Catalyst 5500 switch where they are switched as appropriate.

With a Layer 3-fabric integration module installed in the Catalyst 5500 chassis and a Catalyst 8500 series switch route processor installed in slot 13, you can install Catalyst 8510 CSR Ethernet line modules in the remaining open slots to provide wire-speed Layer 3 switching in the Catalyst 5500 switch.

These hardware and software restrictions apply when using the Layer-3 fabric integration module:

You must use Catalyst 5000 family supervisor engine software release 4.4 or later on the Catalyst 5000 family switch.
A Catalyst 8510 CSR SRP running Cisco 8510 CSR software release 12.0(0.16)W5(3) or later must be installed in slot 13 of the Catalyst 5500 switch. If no SRP is installed, the fabric integration features of the fabric integration module will not function.
The fabric integration module must be installed in slots 9-12 of the Catalyst 5500 switch chassis.

The Layer 3-fabric integration module has one STATUS LED, which provides status information about the module, and eight LINK LEDs, one for each external 100BaseFX Fast Ethernet port connection. The LEDs are described in Table 10-1 .

Table 10-1: Layer 3-Fabric Integration Module (WS-X5305) LED Descriptions

LED	State	Description
STATUS		Indicates a series of self-tests and diagnostic tests.
	Green	All the tests pass.
	Red	A test other than an individual port test failed.
	Orange	System boot, self-test diagnostics running, or the module is disabled.
LINK		Indicates the individual port status.
	Green	The port is operational (a signal is detected).
	Orange	The link has been disabled by software.
	Flashing orange	The link has been disabled due to a hardware failure.
	Off	No signal is detected.

Catalyst 5500 ATM-Fabric Integration Module (WS-X5165)

The ATM-fabric integration module seamlessly integrates the Catalyst 5500 switching fabric and the LightStream 1010 switching fabric in a Catalyst 5500 chassis.

The ATM-fabric integration module, shown in Figure 10-2, installs in the Catalyst 5500 switch in slots 9 through 12 and bridges the 3.6-Gbps media-independent switch fabric and the 5-Gbps cell-switch fabric without the need for external cabling. The module also has one external OC-12 ATM port adapter interface.

Note To use the ATM-fabric integration module in the Catalyst 5500 switch, you must install an ATM switch processor (ASP) in slot 13.

Both the supervisor engine and LightStream 1010 ASP software recognize the ATM-fabric integration module. You can configure the internal interface on the module from the Catalyst 5000 family command-line interface (CLI). You can configure the external OC-12 ATM interface from the LightStream 1010 ASP CLI.

Note The DIAG PORT connector is reserved for manufacturing use.

The Catalyst 5500 ATM-fabric integration module provides these features:

Hot insertion and removal
Support for Multiprotocol over ATM (MPOA)
Permanent virtual connection including PVC traffic shaping support
LAN emulation (LANE) V1 support

These hardware and software guidelines apply when using the ATM-fabric integration module:

You must use Catalyst 5000 family supervisor engine software release 4.3(1) or later on the Catalyst 5000 series switch.
You must use Catalyst 5000 family ATM software release 11.3(5)WA4(8) or later on the ATM-fabric integration module.
A LightStream 1010 ASP running LightStream 1010 software release 12.0(1)W5(5) or later must be installed in slot 13 of the Catalyst 5500 switch. If no ASP is installed, the fabric integration module will not function.
You must install the ATM-fabric integration module in slots 9-12 of the Catalyst 5500 switch.

The ATM-fabric integration module has one LED, which provides status information about the module, and three LEDs, which provide status information about the OC-12 port. The LEDs are described in Table 10-2.
