Network Analysis Module Features

The Network Analysis Module, shown in Figure 1, provides RMON and RMON2 support for Ethernet VLANs to monitor applications and analyze traffic, which extends the Remote Monitoring (RMON) support provided by the Catalyst 5000 series supervisor engine. The module acts as a network data-gathering agent and provides network traffic monitoring when used with a client equipped with network monitoring software. The Network Analysis Module supports the following RMON groups (see the "Supported RMON and RMON2 MIB Objects" section for details):

The Network Analysis Module can analyze Ethernet virtual LAN (VLAN) traffic from either or both:

Note      When monitoring a VLAN or a Fast Ethernet port or more than two Ethernet ports, use a Supervisor Engine III module in the system to ensure the most reliable SNMP access to the Network Analysis Module under heavy traffic conditions.

The Network Analysis Module is managed and controlled from a simple network management protocol (SNMP) management application, such as CiscoWorks2000.

Safety Warnings

Safety warnings appear throughout this configuration note in procedures that, if performed incorrectly, might harm you. A warning symbol precedes each warning statement. This section describes the warning symbol used in this note.

This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. To see translations of the warnings that appear in this publication, refer to the appendix "Translated Safety Warnings" in the Catalyst 5000 Series Installation Guide.

Installing the Network Analysis Module

All Catalyst 5000 series 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 automatically runs diagnostic and discovery routines, acknowledges the presence or absence of the module, and resumes system operation with no operator intervention.

Only trained and qualified personnel should install or replace this equipment.

Tools Required

You need a flat-blade screwdriver to remove any filler (blank) switching modules and to tighten the captive installation screws that secure the modules in their slots. Whenever you handle switching modules, you should use a wrist strap or other grounding device to prevent ESD damage.

Removing Modules

To remove a module from a Catalyst 5000 series switch, perform these steps:

To prevent ESD damage, handle switching modules by the carrier edges only.

Step 1   If you do not plan to reinstall the switching module immediately after removing it, disconnect any network interface cables attached to the switching module ports.

Step 2   Use a flat-blade screwdriver to loosen the captive installation screws, shown in Figure 3.


Figure 3   Ejector Levers and Captive Installation Screws


Step 3   Place your thumbs on the left and right ejector levers and simultaneously push the levers outward to release the module from the backplane connector. Figure 3 shows a close-up of the right ejector lever.

Step 4   Grasp the module handle with one hand and place your other hand under the carrier to support and guide it out of the slot. Avoid touching the module.

Step 5   Carefully pull the switching module straight out of the slot, keeping your other hand under the carrier to guide it. Keep the switching module oriented horizontally.

Step 6   Place the switching module on an antistatic mat or antistatic foam or immediately install it in another slot.

Step 7   If the slot is to remain empty, install a module filler plate (part number 800-00292-01) to keep dust out of the chassis and to maintain proper airflow through the module compartment.

Always install the module filler plate in empty module slots to maintain the proper flow of cooling air across the modules.

Installing Modules

All Catalyst 5000 series modules are installed in horizontal slots that are numbered from top to bottom. Figure 4 shows an example of how slots are numbered on the chassis; in this case using the Catalyst 5000 switch. The slot numbering for all Catalyst 5000 series switches is similar to that shown in Figure 4.


Figure 4   Module Slot Numbers


The Network Analysis Module can be installed in slots 2 through 5 in the Catalyst 5000 and Catalyst 5505 switches, slots 2 through 9 of the Catalyst 5509 switch, and slots 2 through 12 of the Catalyst 5500 switch.

Note      You can install the Network Analysis Module in slot 2 of the Catalyst 5002 switch, but with the supervisor engine module occupying slot 1 of the two-slot chassis, you cannot install any other switching modules.

To install a module in a Catalyst 5000 series switch, perform these steps:

To prevent ESD damage, handle modules by the carrier edges only.

Step 1   Make sure you take the necessary precautions to prevent ESD damage.

Step 2   Choose a slot for the new module. If possible, place modules between empty slots.

Note Empty slots have module filler plates installed.

Step 3   Use a flat-blade screwdriver to loosen the captive installation screws securing the module filler plate (or the existing module) from the desired slot.

Step 4   Remove the module filler plate (or the existing module).

Step 5   Hold the module handle with one hand and place your other hand under the carrier to support the module and guide it into the slot. Avoid touching the printed circuit boards or connector pins.

Step 6   Place the module in the slot. Align the notch on the sides of the module carrier with the groove in the slot, as shown in Figure 5 for the Catalyst 5000 switch. Use the same procedure for all Catalyst 5000 series switches.


Figure 5   Module Installation


Step 7   Maintain the module at a 90-degree orientation to the backplane and carefully slide the module into the slot until the module faceplate contacts the ejector levers.

Step 8   Use the thumb and forefinger of each hand and simultaneously push in the left and the right levers to seat the module in the backplane connector.

Always use the ejector levers when installing or removing modules. A module that is partially seated in the backplane will cause the system to halt and subsequently crash.

Step 9   Use a flat-blade screwdriver to tighten the captive installation screws on the left and right ends of the module.

Step 10   Check the status of the interfaces as follows:

  • If this installation is a replacement module, use the show module command to verify that the system has acknowledged the new module and brought it up.
  • If the module is new, complete the procedures in the following section.

Configuring the Network Analysis Module

Table 3 describes the Network Analysis Module default configuration.

Configuring the Network Analysis Module from the NMS

An SNMP management application, such as CiscoWorks2000, together with the computer it runs on, is called a network management system (NMS). To configure the Network Analysis Module from an NMS, refer to the NMS documentation. RMON domain configuration can be done only through SNMP from the NMS.

Configuring the Network Analysis Module from the CLI

The following sections describe how to use the command line interface (CLI) to configure the Network Analysis Module. For additional information on the CLI, refer to the Catalyst 5000 Series Command Reference publication.

Enabling Traffic Sources

The Network Analysis Module can analyze Ethernet virtual LAN (VLAN) traffic from either or both:

  • The Switched Port Analyzer (SPAN) source: one or more Ethernet ports or a Fast Ethernet port or a Fast Ethernet trunk port or an Ethernet VLAN
  • NetFlow Data Export (NDE) from a NetFlow Feature Card (NFFC or NFFC II) installed on the Supervisor Engine III module

Enable one or both of the Ethernet VLAN network traffic sources. Enable at least one source of Ethernet VLAN network traffic.

Using SPAN as a Traffic Source

If desired, use the SPAN feature as a traffic source for the Network Analysis Module:

    • Set the Network Analysis Module as the SPAN destination port (see the Catalyst 5000 Series Software Configuration Guide for procedures).
    • The Network Analysis Module can analyze Ethernet VLAN traffic from Ethernet or Fast Ethernet SPAN source ports, or you can specify an Ethernet VLAN as the SPAN source.
    • To use the Network Analysis Module VLAN Monitor option (see the "Enabling the VLAN Monitor Option" section), set a trunk port as the SPAN source port.
Using NetFlow Data Export as a Traffic Source

If desired, use NDE as a traffic source for the Network Analysis Module. Enable the NetFlow Monitor option to allow the Network Analysis Module to receive the NDE stream from an NFFC or NFCC II installed in the switch. The resultant statistics are presented on reserved ifIndex.3000.

Note      If you are using software release 5.4(2) and later, the password is not required. Skip steps 2 through 4 in the following procedure if your system is running Release 5.4(2) and later.

To enable the NetFlow Monitor option:

Step 1   Purchase a NetFlow Monitor option license from your Cisco sales representative, which will have a registration key and URL on it.

Step 2   Get the Media Access Control (MAC) address of your Network Analysis Module. Enter this command:

Console> show module mod_num

This example shows how to display the MAC address:

Console> show module 4
Mod Module-Name Ports Module-Type Model Serial-Num Status
--- ------------------- ----- --------------------- --------- --------- -------
4 1 Network Analysis/RMON WS-X5380 008175475 ok
Mod MAC-Address(es) Hw Fw Sw
--- -------------------------------------- ------ ---------- -----------------
4 00-e0-14-10-18-00 0.100 4.1.1 4.3(1)

Note The MAC address in the example is 00-e0-14-10-18-00.

Step 3   Access the URL specified on the NetFlow Monitor option license.

Step 4   Enter the registration key and the MAC address of the Network Analysis Module to generate the password for your Network Analyzer Module.

Step 5   Enter this command in privileged mode to enable the NetFlow Monitor option:

Console> set snmp extendedrmon netflow enable password

This example shows how to enable the NetFlow Monitor option and how to verify that it is enabled:

Console> (enable) set snmp extendedrmon netflow enable password
Snmp extended RMON netflow enabled
Console> (enable) show snmp
RMON: Disabled
Extended RMON: Enabled
Extended RMON Netflow: Enabled
Extended RMON Vlanmode: Disabled
Extended RMON Vlanagent: Disabled
<...output truncated...>
Console> (enable)

Step 6   Enter this command in privileged mode to enable NDE:

Console> set mls nde enable

Note      With a Network Analysis Module installed, you do not need to specify an external data collector with a set mls nde collector_ip [udp_port_number] command as described in the "Configuring Multilayer Switching" chapter of the Catalyst 5000 Series Software Configuration Guide.

Enabling the VLAN Monitor Option

When the SPAN source is a trunk port and the VLAN Monitor option is enabled, the Network Analysis Module aggregates statistics by VLAN, rather than by source MAC address.

To enable the VLAN Monitor option, enter this command in privileged mode:

Task Command

Enable VLAN Monitor.

set snmp extendedrmon vlanmode enable

This example shows how to enable the VLAN Monitor option and how to verify that it is enabled:

Console> (enable) set snmp extendedrmon vlanmode enable
Snmp extended RMON vlanmode enabled
Console> (enable) show snmp
RMON: Disabled
Extended RMON: Enabled
Extended RMON Netflow: Disabled
Extended RMON Vlanmode: Enabled
Extended RMON Vlanagent: Disabled
<...output truncated...>
Console> (enable)

Enabling the VLAN Agents Option

Note      Enabling the VLAN Agents option increases the load on the Network Analysis Module: each packet is counted twice, once as port traffic and once as VLAN traffic.

When the VLAN Agents option is enabled, the Network Analysis Module aggregates statistics by VLAN as well as by port.

To enable the VLAN Agents option, enter this command in privileged mode:

Task Command

Enable VLAN Agents.

set snmp extendedrmon vlanagent enable

This example shows how to enable the VLAN Agents option and how to verify that it is enabled:

Console> (enable) set snmp extendedrmon vlanagent enable
Snmp extended RMON vlanagent enabled
Console> (enable) show snmp
RMON: Disabled
Extended RMON: Enabled
Extended RMON Netflow: Disabled
Extended RMON Vlanmode: Disabled
Extended RMON Vlanagent: Enabled
<...output truncated...>
Console> (enable)
