Note The default TCAM size allocated for access lists by the Switching Database Manager is 1024. If your access list configurations exceed this default size, you can reconfigure the TCAM allocation. See the "Configuring the Switching Database Manager" section for information on allocating TCAM space. |
|
Note Access lists are supported on Gigabit Ethernet interfaces only on the Catalyst 4000 Layer 3 Services module. |
The Catalyst 4000 Layer 3 Services module is a 32-port Layer 2 10/100 Ethernet module with a 4-port Gigabit Ethernet Layer 3 uplink module. The Catalyst 4000 Layer 3 Services module provides interVLAN routing for the Catalyst 4000 family switch and provides Layer 3 switching between the Gigabit Ethernet interfaces.
The Catalyst 4000 Layer 3 Services module occupies a single slot in the chassis and has two internal full-duplex Gigabit Ethernet interfaces that connect directly to the Catalyst 4000 family switch backplane to provide routing capability to all Layer 2 switch ports in the switch. In addition, there are two external Layer 3 Gigabit Ethernet ports that provide a direct connection to external router or switch ports.
The 32 10/100 Ethernet interfaces are configured from the Catalyst 4000 switch supervisor engine. Refer to the software configuration guide for your switch for Layer 2 configuration information. The two external and two internal Gigabit Ethernet interfaces are configured from the Layer 3 services module console. To configure the Layer 3 services module for interVLAN routing, you also must configure the internal Layer 2 Gigabit Ethernet interfaces from the supervisor engine console.
You can group the two internal Gigabit Ethernet interfaces into two trunks or, one Gigabit EtherChannel, or you can configure them as independent interfaces (links). If trunked or channeled, the internal Gigabit Ethernet channel supports trunking using the IEEE 802.1Q protocol. You also can configure each Gigabit Ethernet interface (link) independently as a separate VLAN trunk or nontrunked routed interface.
|
Caution ISL is supported on the external Layer 3 Gigabit Ethernet ports only. The internal Layer 3 Gigabit Ethernet ports on the Catalyst 4000 Layer 3 Services module do not support ISL. Do not configure ISL on the internal Layer 3 ports. |
|
Note The native VLAN can forward tagged and untagged traffic in microcode. This means that Layer 2 and Layer 3 IP, IPX, and multicast traffic is forwarded in microcode.The native VLAN continues to be used for routing protocol traffic and for ARP, ping, CDP, and session-related packets, which are handled by the CPU. |
|
Note The default native VLAN is VLAN 1. You must configure the native VLAN on the Catalyst 4000 Layer 3 Services module and the Catalyst 4000 supervisor engine to match in order to handle CPU-related traffic. |

The following sections describe how to remove and install modules, GBICs, and cables:
Catalyst 4003 and 4006 switches support hot swapping, which lets you install, remove, replace, and rearrange modules without turning off the system power. When the system detects that a module has been installed or removed, it runs diagnostic and discovery routines automatically, acknowledges the presence or absence of the module, and resumes system operation with no operator intervention.
|
Warning Only trained and qualified personnel should install, replace, or service this equipment. |
|
Warning Because invisible laser radiation may be emitted from the aperture of the port when no cable is connected, avoid exposure to laser radiation and do not stare into open apertures. |
You will need these tools to install modules in the Catalyst 4003 and Catalyst 4006 switches:
|
Caution Whenever you handle modules, you should wear a wrist strap or use some other grounding device to prevent ESD damage. |
You might need to remove a module from the switch chassis to make room for the Layer 3 services module. To remove a module from a Catalyst 4003 or Catalyst 4006 switch, perform these steps:
Step 2 Using the Phillips screwdriver, loosen the two captive installation screws (see Figure 3.)
Step 3 Attach an ESD wrist strap to your wrist and to the Catalyst 4003 or Catalyst 4006 switch ESD wrist strap connector.
Step 4 Grasp the left and right ejector levers and pivot both levers outward to release the module from the backplane connector. Figure 3 shows a close-up of the right ejector lever.
|
Caution To prevent ESD damage, handle modules by the carrier edges only. |
Step 5 Grasp the edge of the module front panel with one hand and place your other hand under the carrier to support and guide it out of the slot. Do not touch the printed circuit boards or connector pins.
Step 6 Carefully pull the module straight out of the slot, keeping your other hand under the carrier to guide it.
Step 7 Place the module on an antistatic mat or antistatic foam, or immediately install it in another slot.
Step 8 If the slot is to remain empty, you must install a switching-module filler plate (Cisco part number 800-00292-01) to keep dust out of the chassis and to maintain proper airflow through the module compartment.
|
Warning Blank faceplates (filler panels) serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards and faceplates are in place. |
You have now completed the removal of a module from a Catalyst 4003 or Catalyst 4006 switch.
All Catalyst 4003 and Catalyst 4006 modules are installed in horizontal chassis slots that are numbered from top to bottom. Supervisor engines are installed in slot 1; modules are installed in the remaining slots. Figure 4 shows an example of a supervisor engine and two modules installed in a Catalyst 4003 switch.
To install the Catalyst 4000 Layer 3 Services module in a Catalyst 4003 or Catalyst 4006 switch, perform these steps:
Step 2 Choose a slot for the new module. Ensure that you have enough clearance to accommodate any interface equipment that you will connect directly to the module ports. If possible, place modules between empty slots.
Step 3 Holding the module front panel with one hand, and placing your other hand under the carrier to support the module, as shown in Figure 5, align the edges of the module carrier with the slot guides on the sides of the switch chassis and slide the module halfway into the chassis.
Step 4 Pivot the two module ejector levers out and away from the faceplate. The ejector levers are shown pivoted out in Figure 5.
Step 5 Carefully slide the module the rest of the way into the slot until the notches on both ejector levers engage the chassis sides.
Step 6 Using the thumb and forefinger of each hand, simultaneously pivot in both ejector levers, as shown in Figure 6, to fully seat the module in the backplane connector.
|
Caution Always use the ejector levers when installing or removing modules. A module that is only partially seated in the backplane will cause the system to halt and reset. |
Step 7 Use a screwdriver to tighten the captive installation screws on each end of the module faceplate.
You have now completed the installation of a module in to a Catalyst 4003 or Catalyst 4006 switch.
This section describes how to install GBICs in the Catalyst 4000 Layer 3 Services module.
When handling a GBIC, remember these facts:
GBICs are hot-swappable in the Catalyst 4000 Layer 3 Services module. GBICs have a lifetime of 100 to 500 removals and insertions, so to prevent premature failure of the GBIC, do not remove or insert the GBIC unnecessarily.
When removing or inserting a GBIC, always wear an ESD wrist strap connected to the Catalyst 4003 or Catalyst 4006 switch ESD wrist strap connector.
To install a GBIC, perform these steps:
Step 2 Verify that the GBIC is the correct type for your network by checking the part number: WS-G5484 (1000BASE-SX), WS-G5486 (1000BASE-LX/LH), or WS-G5487 (1000BASE-ZX).
Step 3 Grip the sides of the GBIC with your thumb and forefinger; insert the GBIC into the slot on the front of the module (see Figure 7). GBICs are keyed to prevent incorrect insertion.
Step 4 Slide the GBIC through the flap covering the slot opening. Continue sliding the GBIC into the slot until you hear a click. The click indicates that the GBIC is locked in the slot.
|
Warning Because invisible laser radiation may be emitted from the aperture of the port when no cable is connected, avoid exposure to laser radiation and do not stare into open apertures. |
Step 5 When you are ready to attach the fiber-optic cable, remove the optical bore plug from the GBIC. Save the plug for future use.
|
Note If you are connecting the 1000BASE-LX/LH (WS-G5486) GBICs to an MMF network, you must install a mode-conditioning patch cord. |
You have now completed the installation of a GBIC in to a Catalyst 4003 or Catalyst 4006 module.
When using the LX/LH GBIC with 62.5-micron diameter MMF, you must install a mode-conditioning patch cord (Cisco product number CAB-GELX-625 or equivalent) between the GBIC and the MMF cable on both the transmit and receive ends of the link. The patch cord is required for link distances greater than 984 feet (300 meters). For more information on the patch cord, see the Catalyst 4003 and 4006 Switch Installation Guide.
The patch cord is required to comply with IEEE standards. The IEEE found that link distances could not be met with certain types of fiber-optic cable due to a problem in the center of some fiber-optic cable cores. The solution is to launch light from the laser at a precise offset from the center by using the patch cord. At the output of the patch cord, the LX/LH GBIC is compliant with the IEEE 802.3z standard for 1000BASE-LX. For a detailed description of this problem, refer to the Catalyst 4003 and 4006 Switch Installation Guide.
|
Note We do not recommend using the LX/LH GBIC with MMF without a patch cord for very short link distances (tens of meters) either. The result could be an elevated bit error rate (BER). |
This section describes how to connect the interface cables to the installed Catalyst 4003 and 4006 Layer 3 Services module.
A console serial port (RJ-45) lets you manage your system using standard console equipment.
For RJ-45 connectors, plug the interface cable connector into the receptacle on the module. Push in the connector until you hear a click; the click indicates that the connector is fully inserted and secured in the receptacle.
The 10/100BASE-T port (RJ-45) supports remote console interfaces. This port is for network management only. This port is not a switching port. There is no connectivity between this port and the Gigabit Ethernet switching ports.
For RJ-45 connectors, plug the interface cable connector into the receptacle on the module. Push in the connector until you hear a click; the click indicates that the connector is fully inserted and secured in the receptacle.
|
Warning Because invisible laser radiation may be emitted from the aperture of the port when no cable is connected, avoid exposure to laser radiation and do not stare into open apertures. |
To connect GBICs to the Gigabit Ethernet or Gigabit EtherChannel ports, perform these steps:
Step 2 Remove the plugs from the SC connector (see Figure 8) on the fiber-optic cable. Insert the connector into the GBIC. When you plug the SC connector into the GBIC, make sure that both the transmitter and receiver fiber-optic cables are fully inserted into the SC connector.
Step 3 If you are using the LX/LH GBIC with MMF, install a patch cord between the GBIC and MMF cable.
For RJ-45 connectors, plug the interface cable connector into the receptacle on the module. Push in the connector until you hear a click; the click indicates that the connector is fully inserted and secured in the receptacle.
This section explains how to access the Catalyst 4000 Layer 3 Services module, download an image to bootflash, download an image from the network, and perform an image recovery using Xmodem or Ymodem.
The Catalyst 4000 Layer 3 Services module is configured at the factory to automatically load a Cisco IOS image (router operating system software) the first time you insert the module into a Catalyst 4000 family switch. The module software configuration register, which determines where the Catalyst 4000 Layer 3 Services module loads the image from, is set at the factory to load the IOS image from bootflash (configuration register setting 0x2102). Table 9 shows the default configuration of the Catalyst 4000 Layer 3 Services module.
Table 9 Default Configuration of the Catalyst 4003 and 4006 Layer 3 Services Module
| Feature | Default Value |
| 1You must configure VLAN 1 to be the default VLAN on both the Catalyst 4000 Layer 3 Services module and the Supervisor Engine |
After the Catalyst 4000 Layer 3 Services module goes through power-on self-test diagnostics, and the front panel STATUS LED is green, you can access the Catalyst 4000 Layer 3 Services module console in these two ways:
When you access the Catalyst 4000 Layer 3 Services module for the first time, you need to configure the module is internal interfaces and then save the configuration to a file in NVRAM. From the router console, configure the two external Layer 3 ports for access to another device and configure the two internal ports as trunks, as an EtherChannel, or as independent links to connect through the backplane to the Layer 2 ports in the Catalyst 4000 switch.
The console port allows you to access the Catalyst 4000 Layer 3 Services module either locally (with a console terminal) or remotely (with a modem). The console port is an EIA/TIA-232 asynchronous, serial connection with an RJ-45 connector.
For complete console port cabling specifications and pinouts, refer to the Catalyst 4003 and 4006 Switch Installation Guide.
The console port mode switch allows you to connect a terminal to the Catalyst 4000 Layer 3 Services module using the console cable provided with a Catalyst 4000 family switch. You can also connect a modem to the console port using the cable and adapter provided with the switch.
Put the port mode switch in the "in" position (factory default position) to connect a terminal to the console port using the console cable and data terminal equipment (DTE) adapter (labeled "Terminal"). The console cable and the DTE adapter shipped with the switch.
