Catalyst 4500 Series Switch Cisco IOS Software Configuration Guide, 12.2(31)SGA

Configuring the Catalyst 4500 Series Switch
with Cisco Network Assistant

This chapter describes how to install Network Assistant on the workstation and configure the Catalyst 4500 (or 4900) series switch to communicate with Network Assistant. (Heretofore, the term Catalyst 4500 series switch will be used to refer to both switch types.) It also describes how to create communities and clusters. These are two technologies used by Network Assistant to manage a group of network devices, including the Catalyst 4500 series switch.

Network Assistant is a free network management tool that enables you to configure and manage Catalyst 4500 series switches using a Graphical User Interface (GUI). Network Assistant works in both secure and unsecure environments. Network Assistant manages standalone devices or groups of devices or switches (in communities or clusters) from anywhere in your intranet. Using Network Assistant, you can perform multiple configuration tasks without having to remember commands.

Note For complete syntax and usage information for the switch commands used in this chapter, refer to the Catalyst 4500 Series Switch Cisco IOS Command Reference and related publications at this location:

Network Assistant-Related Features and Their Defaults

Table 1 lists the Network Assistant-related configuration parameters on a Catalyst 4500 series switch.

Overview of the CLI Commands

Table 2 is an overview of the Network Assistant-related CLI commands.

Configuring Your Switch for Network Assistant

The following topics are discussed:

•(Minimum) Configuration Required to Access Catalyst 4500 Accessible from CNA

•(Additional) Configuration Required to use Community

•(Additional) Configuration Required to use Cluster

(Minimum) Configuration Required to Access Catalyst 4500 Accessible from CNA

If you use the default configuration, access the Catalyst 4500 series switch and enter the ip http server (for HTTP) or ip http secure-server (for HTTPS) global configuration command:

Switch# configure terminal

Switch(config)# ip http server

or

Switch(config)# ip domain-name domain_name

Switch(config)# ip http secure-server

Switch(config)# ip http max-connections 
connection_number

Switch(config)# ip http timeout-policy idle 
idle_time life life_time requests requests

Switch(config-if)# end

Switch# show running-config

Note If you have enabled clustering, disable clustering before configuring a community (see Table 2).

(Additional) Configuration Required to use Community

If you plan to use community, define an IP address on each switch:

Switch# configuration terminal

Switch(config)# interface {vlan vlan_ID | 
{fastethernet | gigabitethernet} 
slot/interface | Port-channel number} 

Switch(config-if)# ip address ip_address 
address_mask

Switch(config-if)# end

Switch# show running-config

(Additional) Configuration Required to use Cluster

If you plan to use clustering, enter the cluster run global configuration command on each device and enter the ip address interface configuration command on the cluster commander:

	Command	Purpose
Step 1	Switch# configuration terminal	Enters global configuration mode.
Step 2	Switch(config)# cluster run	Enables clustering. Note Enable clustering on all switches that are part of the potential cluster.
Step 3	Switch(config)# cluster enable	Names the cluster.
Step 4	Switch(config)# interface {vlan vlan_ID | {fastethernet | gigabitethernet} slot/interface | Port-channel number}	Selects an interface.
Step 5	Switch(config-if)# ip address ip_address address_mask	(Optional) Assigns an IP address to the Catalyst 4500 series switch cluster master. Note This step is mandatory if the switch is part of a community or is a cluster command switch. This step is optional if the switch is a cluster member candidate.
Step 6	Switch(config-if)# end	Returns to privileged EXEC mode.
Step 7	Switch# show running-config	Verifies the configuration.

Managing a Network using Community

This section describes how to use communities to manage devices (including Catalyst 4500 series switches, routers, access points, and PIX firewalls) using the Network Assistant application.

When you use communities to group the switches in your network, the only requirements are an HTTP server and that you configure an IP address on each switch.

The total number of devices in the community cannot exceed 20 total devices (including up to 4 Catalyst 4500 series switches (modular), 16 Catalyst 2900/3500 or Catalyst 4948/4948-10GE switches ((non-modular), 2 routers, and 2 PIX firewalls).

Note Access points have been eliminated from the device limits. There is no current limit for the number of access points that can be managed by CNA.

Note The Add to Community dialog display any number of devices, but only allows you to select 20 devices. If you try to add a 21st device, the dialog displays the 21st device and prompts you to select the unwanted device.

Note For complete procedures for using Network Assistant to configure switch communities, refer to
Getting Started with Cisco Network Assistant, available at:

http://www.cisco.com/univercd/cc/td/doc/product/rtrmgmt/cna/v2_0/gsg/index.htm

For the CLI cluster commands, refer to the Catalyst 4500 Series Switch Cisco IOS Command Reference and related publications at:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios122sr/cr/index.htm

This section describes the guidelines, requirements, and caveats that you should understand before you create a community. This section contains the following topics:

•Candidate and Member Characteristics

•Automatic Discovery of Candidates and Members

•Community Names

•Hostnames

•Passwords

•Access Modes in Network Assistant

•Community Information

Candidate and Member Characteristics

Candidates are network devices that have IP addresses but are not part of a community. Members are network devices that are currently part of a community.

To join a community, a candidate must meet these requirements:

•It has an IP address.

•Cisco Discovery Protocol (CDP) version 2 is enabled (the default) - if you want the device to be autodiscovered.

•It has HTTP (or HTTPS) enabled.

Note A cluster member can be added to a community, but the reverse is not possible.

Note If the cluster commander is added to a community, the other member devices of the cluster are not added automatically. The cluster members must be added to the community on an individual basis in order to be managed.

Automatic Discovery of Candidates and Members

Network Assistant forms a community using CDP to locate or discover all the available devices in the network. Beginning with the IP address for a starting device and the port numbers for HTTP (or HTTPS) protocols, Network Assistant uses CDP to compile a list of community candidates that neighbor the starting device. Network Assistant can discover candidate and member devices across multiple networks and VLANs as long as they have valid IP addresses.

Note By default, Network Assistant in community mode discovers up to four hops away.

See the "Candidate and Member Characteristics" section for a list of requirements that network devices must meet in order to be discovered.

Note Do not disable CDP on candidates, members, or on any network devices that you might want Network Assistant to discover.

Note PIX firewalls do not support the CDP, so they are not automatically shown as neighbors in the Topology view. They are shown only after you add them to a community with the Create Community or Modify Community window. To see a PIX firewall link to another community member, you must add the link manually by selecting ADD Link in a Topology popup menu.

You can edit the list of discovered devices to fit your needs and add them to the community. As each device is added to the community, its neighbors are discovered and added to the list of candidate devices. If Network Assistant fails to discover a device you can add it manually through the IP management IP address.

Community Names

When you apply the community configuration information to the list of member devices, Network Assistant requests that you enter a name (or IP address) for the community. You need to assign a name to the community before you can manage it. Network Assistant saves the name to your PC.

The community name can consist of the characters 0-9, a-z and A-Z, with spaces allowed between the characters.

Note You can connect to a cluster only through an IP address. When you select a name it is always for the community.

Hostnames

You do not need to assign a hostname to a starting device or a community member. However, Cisco recommends it and Network Assistant does not assign one by default. If a discovered device does have a hostname, Network Assistant saves it to your PC as identifying information for that device along with its IP address, communication protocol, and designated protocol port.

Passwords

Although you do not need to assign a password to a device if it will become a community member, Cisco recommends that you do so.

Community members can have different passwords.

Communication Protocols

Network Assistant uses the HTTP (or HTTPS) protocols to communicate with network devices. It attempts communication with HTTP (or HTTPS) when using CDP to discover candidate devices.

Access Modes in Network Assistant

When Network Assistant is connected to a community or cluster, two access modes are available: read-write and read-only, depending on the password.

Community Information

Network Assistant saves all community configuration information and individual device information such as IP address, hostname, and communication protocol to your local PC. When Network Assistant connects to a community, it uses the locally saved data to rediscover the member devices.

If you attempt to use a different PC to manage an existing community, the member device information will not be available. You will need to create the community again and add the same member devices.

Adding Devices

There are three ways to add members to a community.

The first uses the Devices Found window on Network Assistant to add devices that you discovered to a new community:

a. In the Devices Found window, select candidate devices that you wish to add.

To add more than one candidate, press Ctrl and make your choices, or press Shift and choose the first and last device in a range.

b. Click Add.

The second way uses the Modify Community window to add devices to an existing community:

a. Choose Application > Communities to open the Communities window.

b. In the Communities window, select the name of the community to which you would like to add a device, and click Modify.

c. To add a single device manually, enter the IP address for the desired device in the Modify Community window, and click Add.

d. To discover candidate devices, enter the IP address for the starting device, and click Discover.

e. Select a candidate device from the list, click Add, and click OK.

To add more than one candidate, press Ctrl and make your choices, or press Shift and choose the first and last device in a range.

The third way to add a device uses the Topology view:

a. If the Topology view is not displayed, choose View window> Topology from the feature bar.

b. Right-click a candidate icon, and select Add to Community.

Candidates are cyan; members are green. To add more than one candidate, press Ctrl and left-click the candidates that you want to add.

When a community has 20 members, the Add to Community option is not available for that community. In this case, you must remove a member before adding a new one.

Note If you are logged into a community and you delete that community from some other CNA instance, then unless you close that community session, you can perform all the configurations through that session. After you close that session (and thereby delete the community), you will not be able to connect to that community.

Converting a Cluster into a Community

The Cluster Conversion wizard helps you convert a cluster into a community. When you complete the conversion, you can immediately manage the device group as a community. The benefits of managing a community is that the communication with the devices in a community is more secure (through multiple passwords and HTTPS) than in a cluster. Moreover, device availability is greater, and the range of devices that can be members is broader.

Note The Cluster Conversion wizard does not alter your cluster definition. This means that you can still manage the devices as a cluster.

To launch the Cluster Conversion Wizard, follow these steps:

Step 1 Start Network Assistant and connect to an existing cluster through its commander IP address.

Step 2 In the feature bar, click Configure > Cluster > Cluster Conversion Wizard.

You will see the query "Do you want to convert this cluster to a community?"

Step 3 Select Yes to proceed or No if you want to manually bring up the Cluster Conversion Wizard.

If you select Yes, the Welcome screen appears, providing information about clusters, communities, and their benefits.

Next, a table appears listing the devices in the cluster starting with those that have no IP address and subnet mask. Be aware that all the devices in the cluster must have an IP address and subnet mask to be members of a community.

Note If a device has more than one interface with an IP address and subnet mask, you see more than one interface listed when you click in the cell. You can choose a different interface from the one originally shown.

Step 4 In the IP Address column, enter an IP address for each device that does not have one.

Step 5 In the Subnet Mask column, click in the cell for each device that does not have a subnet mask and select one.

Step 6 Enter a name for the community.

Step 7 Click Finish to begin the conversion.

When the conversion completes, Network Assistant restarts and automatically connects to the newly created community.

Note If you have enabled clustering, you should disable clustering before configuring a community (see Table 2).

Managing a Network using Cluster

This section describes how to use clustering to create and manage Catalyst 4500 series switches using the standalone Network Assistant application or the command-line interface (CLI).

You can use clustering to group the switches in your network. You must enter the cluster run command on each switch to be managed. The major advantage is that you can manage 16 devices with one IP address.

Note Clustering is the auto- discovering mechanism used in CNA 1.0.

Note For complete procedures for using Network Assistant to configure switch clusters, refer to
Getting Started with Cisco Network Assistant, available at:

http://www.cisco.com/univercd/cc/td/doc/product/rtrmgmt/cna/v2_0/gsg/index.htm

For the CLI cluster commands, refer to the Catalyst 4500 Series Switch Cisco IOS Command Reference and related publications at:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios122sr/cr/index.htm

This section contains the following topics:

•Understanding Switch Clusters

•Using the CLI to Manage Switch Clusters

Understanding Switch Clusters

These sections describe:

•Clustering Overview

•Cluster Command Switch Characteristics

•Candidate Switch and Cluster Member Switch Characteristics

Clustering Overview

A switch cluster is a set of up to 16 connected, cluster-capable Catalyst switches that are managed as a single entity. The switches in the cluster use the switch clustering technology so that you can configure and troubleshoot a group of different Catalyst 4500 series switch platforms through a single IP address.

Using switch clusters simplifies the management of multiple switches, regardless of their physical location and platform families.

Note By default, Network Assistant in clustering mode discovers up to seven hops away.

In a switch cluster, one switch must be the cluster commander switch, and up to 15 other switches can be cluster member switches. The total number of switches in a cluster cannot exceed 16 switches. The cluster command switch is the single point of access used to configure, manage, and monitor the cluster member switches. Cluster members can belong to only one cluster at a time.

Note Always choose a Catalyst 4500 or 4948 series switch as the cluster command switch.

Cluster Command Switch Characteristics

A cluster command switch must meet these requirements:

•It is using Cisco IOS Release 12.2(20)EWA or later.

•It has an IP address.

•It has Cisco Discovery Protocol (CDP) version 2 enabled (the default).

•It is using cluster-capable software and has clustering enabled.

•It has IP HTTP (or HTTPS) server enabled.

Note On a Catalyst 4500 series switch, neither HTTP or HTTPS is enabled by default.

•It has 16 VTY lines.

Note On a Catalyst 4500 series switch, the default is 4 lines. You configure the switch to set the value to 16.

•It is not a command or cluster member switch of another cluster.

Note If your switch cluster contains a Catalyst 4500 series switch, the cluster command switch must also be a Catalyst 4500 series switch.

Network Assistant and VTY

Network Assistant uses virtual terminal (VTY) lines to communicate with the cluster command device. Catalyst 4500 series switches have 5 VTY lines configured by default. Network Assistant can employ an additional 8 lines. Therefore, you should configure the maximum number of lines (or at least, 8 + 5 = 13) so that Network Assistant can communicate with the switch and not use VTY lines that might be needed for telnet.

You can configure the Catalyst 4500 series switch to support an appropriate number of VTY lines with the line vty configuration command. For example, the line vty 6 15 command configures the switch to include 9 VTY lines.

Note If your existing VTY lines have non-default configurations, you might want to apply those configurations to the new VTY lines.

Candidate Switch and Cluster Member Switch Characteristics

Candidate switches are cluster-capable switches that are not part of a cluster. Cluster member switches are switches that are currently part of a switch cluster. Although not required, a candidate or cluster member switch can have its own IP address and password.

Note The hostname of a candidate should not be in the form [a-zA-Z0-9]-n, where n is 0-16. These names are reserved.

To join a cluster, a candidate switch must meet these requirements:

•It is running cluster-capable software and has clustering enabled.

•It has CDP version 2 enabled.

•It has HTTP server enabled.

Note Even when HTTP is enabled on the commander switch, communication between the commander switch and member switch is still carried over HTTP. So, it is not secure.

•It has 16 VTY lines.

•It is not a command or cluster member switch of another cluster.

•It is connected to the cluster command switch through at least one common VLAN.

It is recommended that you configure the Catalyst 4500 candidate and cluster member switches with an SVI on the VLAN connection to the cluster command switch.

Using the CLI to Manage Switch Clusters

You can configure cluster member switches from the CLI by first logging in to the cluster command switch. Enter the rcommand user EXEC command and the cluster member switch number to start a Telnet session (through a console or Telnet connection) and to access the cluster member switch CLI. The command mode changes and the Cisco IOS commands operate as usual. Enter the exit privileged EXEC command on the cluster member switch to return to the command-switch CLI.

This example shows how to log in to member-switch 3 from the command-switch CLI:

switch# rcommand 3

If you do not know the member-switch number, enter the show cluster members privileged EXEC command on the cluster command switch. For more information about the rcommand command and all other cluster commands, refer to the Catalyst 4500 Series Switch Cisco IOS Command Reference.

The Telnet session accesses the member-switch CLI at the same privilege level as on the cluster command switch. The Cisco IOS commands then operate as usual. For instructions on configuring the switch for a Telnet session, see the "Accessing the CLI Through Telnet" section on page 2-2.

Note CISCO-CLUSTER_MIB is not supported.

Configuring Network Assistant in Community or Cluster Mode

This section provides a detailed explanation of the CLI used to configure Network Assistant to work in a community or cluster. Network Assistant communicates with a Catalyst 4500 series switch by sending Cisco IOS commands over an HTTP (or HTTPS) connection.

The following topics are discussed:

•Configuring Network Assistant in on a Networked Switch in Community Mode

•Configuring Network Assistant in a Networked Switch in Cluster Mode

Configuring Network Assistant in on a Networked Switch in Community Mode
