NoteFor system requirements and for browser and Java plug-in configuration procedures, refer to the release notes.

For procedures for using CMS, refer to the online help.



Note This chapter describes the CMS interface of the Catalyst 2950 switches. Refer to the appropriate switch documentation for descriptions of the web-based management software used on other Catalyst switches.


Features

CMS provides these features (Figure 2-1) for managing switch clusters and individual switches from Web browsers such as Netscape Communicator or Microsoft Internet Explorer:

Two views of your network that can be displayed at the same time:

The Front Panel view displays the front-panel image of a specific switch or the front-panel images of all switches in a cluster. From this view, you can select multiple ports or multiple switches and configure them with the same settings.

When CMS is launched from a command switch, the Front Panel view displays the front-panel images of all switches in the cluster. When CMS is launched from a noncommand switch, the Front Panel view displays only the front panel of the specific switch.


Note CMS from a standalone switch or from a noncommand switch is referred to as Device Manager (also referred to as Switch Manager). Device Manager is for configuring an individual switch. When you select Device Manager for a specific switch in the cluster, you launch a separate CMS session. The Device Manager interface can vary between the Catalyst switch platforms.


The Topology view displays a network map that uses icons that represent switch clusters, cluster members, cluster candidates, neighboring devices that are not eligible to join a cluster, and link types. From this view, you can select multiple switches and configure them to run with the same settings. You can also display link information in the form of link reports and link graphs.

This view is available only when CMS is launched from a command switch.

Menus and toolbar to access configuration and management options:

The menu bar provides the complete list of options for managing a single switch and switch clusters.

The toolbar provides buttons for commonly used switch and cluster configuration options and information windows such as legends and online help.

The port popup menu, in the Front Panel view, provides options specific for configuring and monitoring switch ports.

The device popup menu, in either the Front Panel or the Topology views, provides switch and cluster configuration and monitoring options.

The candidate, member, and link popup menus provide options for configuring and monitoring devices and links in the Topology view.

The toolbar and popup menus provide quick ways to access frequently used menu-bar options.

Tools to simplify configuration tasks:

Interactive modes—guide mode and expert mode—that control the presentation of some complex configuration options

Wizards that require minimal information from you to configure some complex features

Comprehensive online help that provides high-level concepts and procedures for performing tasks from the window

Two levels of access to the configuration options: read-write access for users allowed to change switch settings; read-only access for users allowed to only view switch settings

Consistent set of GUI components (such as tabs, buttons, drop-down lists, tables, and so on) for a consistent approach to setting configuration parameters

Figure 2-1 CMS Features

Front Panel View

When CMS is launched from a command switch, the Front Panel view displays the front-panel images of all switches in the cluster (Figure 2-2). When CMS is launched from a standalone or non-command member switch, the Front Panel view displays only the front panel of the specific switch (Figure 2-3).

Figure 2-2 Front Panel View from a Standalone Switch

 

Figure 2-3 Front Panel View from a Command Switch

Cluster Tree

The cluster tree (Figure 2-3) appears in the left frame of the Front Panel view and shows the name of the cluster and a list of its members. The sequence of the cluster-tree icons (Figure 2-4) mirror the sequence of the front-panel images. You can change the sequence by selecting View > Arrange Front Panel. The colors of the devices in the cluster tree reflect the status of the devices (Table 2-1).

If you want to configure switch or cluster settings on one or more switches, select the appropriate front-panel images.

To select a front-panel image, click either the cluster-tree icon or the corresponding front-panel image. The front-panel image is then highlighted with a yellow outline.

To select multiple front-panel images, press the Ctrl key, and left-click the cluster-tree icons or the front-panel images. To deselect an icon or image, press the Ctrl key, and left-click the icon or image.

If the cluster has many switches, you might need to scroll down the window to display the rest of front-panel images. Instead of scrolling, you can click an icon in the cluster tree, and CMS then scrolls and displays the corresponding front-panel image.

Figure 2-4 Cluster-Tree Icons

Table 2-1 Cluster Tree Icon Colors

Device Status

Green

Switch is operating normally.

Yellow

The internal fan of the switch is not operating, or the switch is receiving power from an RPS.

Red

Switch is not powered up, has lost power, or the command switch is unable to communicate with the member switch.


Front-Panel Images

You can manage the switch from a remote station by using the front-panel images. The front-panel images are updated based on the network polling interval that you set from CMS > Preferences.


Note The Preferences window is not available if your switch access level is read-only. For more information about the read-only access mode, see the "Access Modes in CMS" section.


Figure 2-5 shows the port icons as they appear in the front-panel images. To select a port, click the port on the front-panel image. The port is then highlighted with a yellow outline. To select multiple ports, you can:

Press the left mouse button, drag the pointer over the group of ports that you want to select, and then release the mouse button.

Press the Ctrl key, and click the ports that you want to select.

Right-click a port, and select Select All Ports from the port popup menu.

Figure 2-5 Port Icons

The following sections provide complete descriptions of the LED images. Similar descriptions of these LEDs are provided in the switch hardware installation guide.

Redundant Power System LED

The Redundant Power System (RPS) LED shows the RPS status (Table 2-2). Certain switches in the switch cluster use a specific RPS model:

Cisco RPS 300 (model PWR300-AC-RPS-N1)—Catalyst 2900 LRE XL, Catalyst 2950, Catalyst 3524-PWR XL, and Catalyst 3550 switches

Cisco RPS 600 (model PWR600-AC-RPS)—Catalyst 2950 switches, except the Catalyst 2900 LRE XL and Catalyst 3524-PWR XL switches

Refer to the appropriate switch hardware documentation for RPS descriptions specific for the switch.

Table 2-2 RPS LED

Color
RPS Status

Black (off)

RPS is off or is not installed.

The RPS could be in standby mode. To put the RPS in Active mode, press the Standby/Active button on the RPS, and the LED should turn green. If it does not, one of these conditions could exist:

One of the RPS power supplies could be down. Contact Cisco Systems.

The RPS fan could have failed. Contact Cisco Systems.

Blinking amber

Internal power supply of the switch is down, and redundancy is lost. The switch is operating on the RPS.


Port Modes and LEDs

The port modes (Table 2-3) determine the type of information displayed through the port LEDs. When you change port modes, the meanings of the port LED colors (Table 2-4) also change.


Note The bandwidth utilization mode (UTL LED) does not appear on the front-panel images. Select Reports > Bandwidth Graphs to display the total bandwidth in use by the switch. Refer to the switch hardware installation guide for information about using the UTL LED.


To select or change a mode, click the Mode button until the desired mode LED is green.

Topology View

The Topology view displays how the devices within a switch cluster are connected and how the switch cluster is connected to other clusters and devices. From this view, you can add and remove cluster members. This view provides two levels of detail of the network topology:

When you right-click a cluster icon and select Expand Cluster, the Topology view displays the switch cluster in detail. This view shows the command switch and member switches in a cluster. It also shows candidate switches that can join the cluster. This view does not display the details of any neighboring switch clusters (Figure 2-6).

When you right-click a command-switch icon and select Collapse Cluster, the cluster is collapsed and represented by a single icon. The view shows how the cluster is connected to other clusters, candidate switches, and devices that are not eligible to join the cluster (such as routers, access points, IP phones, and so on) (Figure 2-7).


Note The Topology view displays only the switch cluster and network neighborhood of the specific command or member switch that you access. To display a different switch cluster, you need to access the command switch or member switch of that cluster.


You can arrange the device icons in this view. To move a device icon, click and drag the icon. To select multiple device icons, you can either:

Press the left mouse button, drag the pointer over the group of device icons that you want to select, and then release the mouse button.

Press the Ctrl key, and click the device icons that you want to select.

After selecting the icons, drag the icons to any area in the view.

Figure 2-6 Expand Cluster View

Figure 2-7 Collapse Cluster View

Topology Icons

The Topology view and the cluster tree use the same set of device icons to represent clusters, command and standby command switches, and member switches (Figure 2-8). The Topology view also uses additional icons to represent these types of neighboring devices:

Customer premises equipment (CPE) devices that are connected to Long-Reach Ethernet (LRE) switches

Devices that are not eligible to join the cluster, such as Cisco IP phones, Cisco access points, and Cisco Discovery Protocol (CDP)-capable hubs and routers

Devices that are identified as unknown devices, such as some Cisco devices and third-party devices


Note Candidate switches are distinguished by the color of their device label. Device labels and their colors are described in the "Colors in the Topology View" section.


To select a device, click the icon. The icon is then highlighted. To select multiple devices, you can either:

Press the left mouse button, drag the pointer over the group of icons that you want to select, and then release the mouse button.

Press the Ctrl key, and click the icons that you want to select.

Figure 2-8 Topology-View Device Icons

The Topology view also uses a set of link icons (Figure 2-9) to show the link type and status between two devices. To select a link, click the link that you want to select. To select multiple links, press the Ctrl key, and click the links that you want to select.

Figure 2-9 Topology-View Link Icons

Device and Link Labels

The Topology view displays device and link information by using these labels:

Cluster and switch names

Switch MAC and IP addresses

Link type between the devices

Link speed and IDs of the interfaces on both ends of the link

When using these labels, keep these considerations in mind:

The IP address displays only in the labels for the command switch and member switches.

The label of a neighboring cluster icon only displays the IP address of the command-switch IP address.

The displayed link speeds are the actual link speeds except on the LRE links, which display the administratively assigned speed settings.

You can change the label settings from the Topology Options window, which is displayed by selecting View > Topology Options.

Colors in the Topology View

The colors of the Topology view icons reflect the status of the devices and links (Table 2-6, Table 2-7, and Table 2-8).

Topology Display Options

You can set the type of information displayed in the Topology view by changing the settings in the Topology Options window. To display this window, select View > Topology Options. From this window, you can select:

Device icons to be displayed in the Topology view

Labels to be displayed with the device and link icons

Menus and Toolbar

The configuration and monitoring options for configuring switches and switch clusters are available from the menu bar, toolbar, and the Front-Panel and Topology view popup menus.

Menu Bar

The menu bar provides the complete list of options for managing a single switch and switch cluster. The menu bar is the same whether or not the Front-Panel or Topology views are displayed.

Options displayed from the menu bar can vary:

The option for enabling a command switch is only available from a CMS session launched from a command-capable switch.

Cluster management tasks, such as upgrading the software of groups of switches, are available only from a CMS session launched from a command switch.

If you launch CMS from a specific switch, the menu bar displays the features supported only by that switch.

If you launch CMS from a command switch, the menu bar displays the features supported on the switches in the cluster, with these exceptions:

If the command switch is a Layer 3 switch, such as a Catalyst 3550 switch, the menu bar displays the features of all Layer 3 and Layer 2 switches in the cluster.

If the command switch is a Layer 2 switch, such as a Catalyst 2950 or Catalyst 3500 XL switch, the menu bar displays the features of all Layer 2 switches in the cluster. The menu bar does not display Layer 3 features even if the cluster has Catalyst 3550 Layer 3 member switches.


Note We strongly recommend that the highest-end, command-capable switch in the cluster be the command switch so that all of the features supported in the cluster are displayed from the menu bar. If you have a switch cluster with a Catalyst 3550, that switch should be the command switch. If your switch cluster has Catalyst 2900 XL, Catalyst 2950, and Catalyst 3500 XL switches, the Catalyst 2950 should be the command switch. Refer to the release notes for the Catalyst switches that can be part of a switch cluster.



NoteUnless noted otherwise, Table 2-10 lists the menu-bar options available from a Catalyst 2950 command switch and when the cluster contains only Catalyst 2950 member switches. The menu bar of the command switch displays all menu-bar options available from the cluster, including options from member switches from other cluster-capable switch platforms.

The menu-bar options on a Catalyst 2950 switch change depending on whether the switch is running the enhanced software image or not. The footnotes for Table 2-10 list the options available if the switch is running the enhanced software image.

The footnotes in the table describe the availability of an option based on your access mode in CMS: read-only (access level 1-14) and read-write (access level 15). For more information about CMS access modes, see the "Access Modes in CMS" section.

If your cluster has these member switches running earlier software releases and if you have read-only access to these member switches, some configuration windows for those switches display incomplete information:

Catalyst 2950 member switches running Cisco IOS Release 12.0(5)WC2 or earlier

Catalyst 2950 member switches running Cisco IOS Release 12.0(5)WC2 or earlier

Catalyst 3550 member switches running Cisco IOS Release 12.1(6)EA1 or earlier

For more information about this limitation, refer to the Catalyst 2950 release notes.

These switches do not support CMS access modes:

Catalyst 1900 and Catalyst 2820

Catalyst 2900 XL switches with 4-MB CPU DRAM

If these switches are in a cluster that is using CMS access levels, these switches appear as unavailable devices and cannot be configured from CMS.

Interaction Modes

You can change the interaction mode of CMS to either guide or expert mode. Guide mode steps you through each feature option and provides information about the parameter. Expert mode displays a configuration window in which you configure the feature options.

Guide Mode


Note Guide mode is not available if your switch access level is read-only. For more information about the read-only access mode, see the "Access Modes in CMS" section.


Guide mode is for users who want a step-by-step approach for completing a specific configuration task. This mode is not available for all features. A menu-bar option that has a person icon means that guide mode is available for that option.

When you click Guide Mode and then select a menu-bar option that supports guide mode, CMS displays a specific parameter of the feature with information about the parameter field. To configure the feature, you provide the information that CMS requests in each step until you click Finish in the last step. Clicking Cancel at any time closes and ends the configuration task without applying any changes.

If Expert Mode is selected and you want to use guide mode, you must click Guide Mode before selecting an option from the menu bar, tool bar, or popup menu. If you change the interaction mode after selecting a configuration option, the mode change does not take effect until you select another configuration option.

Expert Mode

Expert mode is for users who prefer to display all the parameter fields of a feature in a single CMS window. Information about the parameter fields are provided from Help.

Wizards


Note Wizards are not available if your switch access level is read-only. For more information about the read-only access mode, see the "Access Modes in CMS" section.


Wizards simplify some configuration tasks on the switch. Similar to the guide mode, wizards provide a step-by-step approach for completing a specific configuration task. Unlike guide mode, a wizard does not prompt you to provide information for all of the feature options. Instead, it prompts you to provide minimal information and then uses the default settings of the remaining options to set up default configurations.

Wizards are not available for all features. A menu-bar option that has wizard means that selecting that option launches the wizard for that feature.

Tool Tips

CMS displays a popup message when you move your mouse over these devices:

A yellow device icon in the cluster tree or in Topology view—A popup displays a fault message, such as that the RPS is faulty or that the switch is unavailable because you are in read-only mode.

A red device icon in the cluster tree or in Topology view—A popup displays a message that the switch is down.

If you move your mouse over a table column heading, a popup displays the full heading.

CMS Window Components

CMS windows consistently present configuration information. Figure 2-12 shows the components of a typical CMS window.

Figure 2-12 CMS Window Components

Host Name List

To display or change the configuration of a cluster member, you need to select the specific switch from the Host Name drop-down list. The list appears in the configuration window of each feature and lists only the cluster members that support that feature. For example, the Host Name list on the VLAN window does not include Catalyst 1900 and Catalyst 2820 switches even though they are part of the cluster. Similarly, the Host Name list on the LRE Profiles window only lists the LRE switches in the cluster.

Tabs, Lists, and Tables

Some CMS windows have tabs that present different sets of information. Tabs are arranged like folder headings across the top of the window. Click the tab to display its information.

Listed information can often be changed by selecting an item from a list. To change the information, select one or more items, and click Modify. Changing multiple items is limited to those items that apply to at least one of the selections.

Some CMS windows present information in a table format. You can edit the information in these tables.


Note You can resize the width of the columns to display the column headings, or you can hover your cursor over the heading to display a popup description of the column.


Icons Used in Windows

Some window have icons for sorting information in tables, for showing which cells in a table are editable, and for displaying further information from Cisco.com (Figure 2-13).

Figure 2-13 Window Icons

Buttons

These are the most common buttons that you use to change the information in a CMS window:

OK—Save any changes and close the window. If you made no changes, the window closes. If CMS detects errors in your entry, the window remains open. For more information about error detection, see the "Error Checking" section.

Apply—Save any changes made in the window and leave the window open. If you made no changes, the Apply button is disabled.

Refresh—Update the CMS window with the latest status of the device. Unsaved changes are lost.

Cancel—Do not save any changes made in the window and close the window.

Help—Display procedures on performing tasks from the window.

Modify—Display the secondary window for changing information on the selected item or items. You usually select an item from a list or table and click Modify.

Accessing CMS

This section assumes the following:

You know the IP address and password of the command switch or a specific switch. This information is either:

Assigned to the switch by following the setup program, as described in the release notes.

Changed on the switch by following the information in the "Changing IP Information" section and "Changing the Password" section. Considerations for assigning IP addresses and passwords to a command switch and cluster members are described in the "IP Addresses" section and "Passwords" section.

You know your access privilege level to the switch.

You have referred to the release notes for system requirements and have followed the procedures for installing the required Java plug-ins and configuring your browser.


Caution Copies of the CMS pages you display are saved in your browser memory cache until you exit the browser session. A password is not required to redisplay these pages, including the Cisco Systems Access page. You can access the CLI by clicking Monitor the router - HTML access to the command line interface from a cached copy of the Cisco Systems Access page. To prevent unauthorized access to CMS and the CLI, exit your browser to end the browser session.

To access CMS, follow these steps:


Step 1 Enter the switch IP address and your privilege level in the browser Location field (Netscape Communicator) or Address field (Microsoft Internet Explorer). For example:

http://10.1.126.45:184/level/14/

where 10.1.126.45 is the switch IP address, 184 is the HTTP port, and level 14 is the privilege level. You do not need to enter the HTTP port if the switch is using HTTP port 80 (the default) or enter the privilege level if you have read-write access to the switch (privilege level is 15). For information about the HTTP port, see the "HTTP Access to CMS" section. For information about privilege levels, see the "Access Modes in CMS" section.

Step 2 When prompted for a username and password, enter only the switch enable password. CMS prompts you a second time for a username and password. Enter only the enable password again.

If you configure a local username and password, make sure you enable it by using the ip http authentication global configuration command. Enter your username and password when prompted.

Step 3 Click Web Console.

If you access CMS from a standalone or member switch, Device Manager appears. If you access CMS from a command switch, you can display the Front Panel and Topology views.


Access Modes in CMS

CMS provides two levels of access to the configuration options: read-write access and read-only access. Privilege levels 0 to 15 are supported.

Privilege level 15 provides you with read-write access to CMS.

Privilege levels 1 to 14 provide you with read-only access to CMS. Any options in the CMS windows, menu bar, toolbar, and popup menus that change the switch or cluster configuration are not shown in read-only mode.

Privilege level 0 denies access to CMS.

If you do not include a privilege level when you access CMS, the switch verifies if you have privilege-level 15. If you do not, you are denied access to CMS. If you do have privilege-level 15, you are granted read-write access. Therefore, you do not need to include the privilege level if it is 15. Entering zero denies access to CMS. For more information about privilege levels, see the "Changing the Password" section.


NoteIf your cluster has these member switches running earlier software releases and if you have read-only access to these member switches, some configuration windows for those switches display incomplete information:

Catalyst 2950 member switches running Cisco IOS Release 12.0(5)WC2 or earlier

Catalyst 2950 member switches running Cisco IOS Release 12.0(5)WC2 or earlier

Catalyst 3550 member switches running Cisco IOS Release 12.1(6)EA1 or earlier

For more information about this limitation, refer to the Catalyst 2950 release notes.

These switches do not support read-only mode on CMS:

Catalyst 1900 and Catalyst 2820

Catalyst 2900 XL switches with 4-MB CPU DRAM

In read-only mode, these switches appear as unavailable devices and cannot be configured from CMS.


Verifying Your Changes

CMS provides notification cues to help you track and confirm the changes you make.

Change Notification

A green border around a field or table cell means that you made an unsaved change to the field or table cell. Previous information in that field or table cell is displayed in the window status bar. When you save the changes or if you cancel the change, the green border disappears.

Error Checking

A red border around a field means that you entered invalid data in the field. An error message also displays in the window status bar. When you enter valid data in the field, a green border replaces the red border until you either save or cancel the change.

If there is an error in communicating with the switch or if you make an error while performing an action, a popup dialog notifies you about the error.

Saving Your Changes


Note The Save Configuration option is not available if your switch access level is read-only. For more information about the read-only access mode, see the "Access Modes in CMS" section.



Tip As you make cluster configuration changes (except for changes to the Topology view and in the Preferences window), make sure that you periodically save the configuration from the command switch. The configuration is saved on the command and member switches.


The front-panel images and CMS windows always display the running configuration of the switch. When you make a configuration change to a switch or switch cluster, the change becomes part of the running configuration. The change does not automatically become part of the config.txt file in Flash memory, which is the startup configuration used each time the switch restarts. If you do not save your changes to Flash memory, they are lost when the switch restarts.

To save all configuration changes to Flash memory, you must select Administration > Save Configuration.


Note Catalyst 1900 and Catalyst 2820 switches automatically save configuration changes to Flash memory as they occur.


Using Different Versions of CMS

When managing switch clusters through CMS, remember that clusters can have a mix of switch models using different IOS releases and that CMS in earlier IOS releases and on different switch platforms might look and function differently from CMS in this IOS release.

When you select Device > Device Manager for a cluster member, a new browser session is launched, and the CMS version for that switch is displayed.

Here are examples of how CMS can differ between IOS releases and switch platforms:

On Catalyst switches running Cisco IOS Release 12.0(5)WC2 or earlier or Cisco IOS Release 12.1(6)EA1 or earlier, the CMS versions in those software releases might appear similar but are not the same as this release. For example, the Topology view in this release is not the same as the Topology view or Cluster View in those earlier software releases.

CMS on the Catalyst 1900 and Catalyst 2820 switches is referred to as Switch Manager. Cluster management options are not available on these switches. This is the earliest version of CMS.

Refer to the documentation specific to the switch and its IOS release for descriptions of the CMS version you are using.
