Getting Started

This section provides an introduction to the web-based configuration utility, and covers the following topics:

• Starting the Web-based Configuration Utility

• Quick Start Device Configuration

• Interface Naming Conventions

• Window Navigation

Starting the Web-based Configuration Utility

This section describes how to navigate the web-based switch configuration utility.

If you are using a pop-up blocker, make sure it is disabled.

Browser Restrictions

If you are using IPv6 interfaces on your management station, use the IPv6 global address and not the IPv6 link local address to access the device from your browser.

Launching the Configuration Utility

To open the web-based configuration utility:

STEP 1 Open a Web browser.

STEP 2 Enter the IP address of the device you are configuring in the address bar on the

browser, and then press Enter.

NOTE When the device is using the factory default IP address of 192.168.1.254, its power

LED flashes continuously. When the device is using a DHCP-assigned IP address or an administrator-configured static IP address, the power LED is on solid.

Cisco Small Business 200 Series Smart Switch Administration Guide 8

Getting Started

Starting the Web-based Configuration Utility

Logging In

The default username is cisco and the default password is cisco. The first time that you log in with the default username and password, you are required to enter a new password.

NOTE If you have not previously selected a language for the GUI, the language of the Login

page is determined by the language(s) requested by your browser and the languages configured on your device. If your browser requests Chinese, for example, and Chinese has been loaded into your device, the Login page is automatically displayed in Chinese. If Chinese has not been loaded into your device, the Login page appears in English.

The languages loaded into the device have a language and country code (en-US, en-GB and so on). For the Login page to be automatically displayed in a particular language, based on the browser request, both the language and country code of the browser request must match those of the language loaded on the device. If the browser request contains only the language code without a country code (for example: fr). The first embedded language with a matching language code is taken (without matching the country code, for example: fr_CA).

To log in to the device configuration utility:

STEP 1 Enter the username/password. The password can contain up to 64 ASCII

characters. Password-complexity rules are described in Setting Password

Complexity Rules.

STEP 2 If you are not using English, select the desired language from the Language drop-

down menu. To add a new language to the device or update a current one, see

Upgrade/Backup Firmware/Language.

STEP 3 If this is the first time that you logged on with the default user ID (cisco) and the

default password (cisco) or your password has expired, the Change Password Page appears. See Password Expiration for additional information.

STEP 4 Choose whether to select Disable Password Complexity Enforcement or not.

For more information on password complexity, see the Setting Password

Complexity Rules section.

STEP 5 Enter the new password and click Apply.

When the login attempt is successful, the Getting Started page appears.

If you entered an incorrect username or password, an error message appears and the Login page remains displayed on the window. If you are having problems logging in, please see the Launching the

Configuration Utility section in the Administration Guide for additional information.

Cisco Small Business 200 Series Smart Switch Administration Guide 9

Getting Started

Starting the Web-based Configuration Utility

Select Don't show this page on startup to prevent the Getting Started page from being displayed each time that you log on to the system. If you select this option, the System Summary page is opened instead of the Getting Started page.

HTTP/HTTPS

You can either open an HTTP session (not secured) by clicking Log In, or you can open an HTTPS (secured) session, by clicking Secure Browsing (HTTPS). You are asked to approve the logon with a default RSA key, and an HTTPS session is opened.

NOTE There is no need to input the username/password prior to clicking the Secure

Browsing (HTTPS) button.

For information on how to configure HTTPS, see SSL Server.

Password Expiration

The New Password page is displayed in the following cases:

• The first time that you access the device with the default username cisco and password cisco. This

page forces you to replace the factory default password.

• When the password expires, this page forces you to select a new password.

Logging Out

By default, the application logs out after ten minutes of inactivity. You can change this default value as described in the Defining Idle Session Timeout section.

CAUTION Unless the Running Configuration is copied to the Startup Configuration, rebooting

the device removes all changes made since the last time the file was saved. Save the Running Configuration to the Startup Configuration before logging off to preserve any changes you made during this session.

A flashing red X icon to the left of the Save application link indicates that Running Configuration changes have not yet been saved to the Startup Configuration file. The flashing can be disabled by clicking on the Disable Save Icon Blinking button on the Copy/Save Configuration page

When the device auto-discovers a device, such as an IP phone (see What is a

Smartport), and it configures the port appropriately for the device. These

configuration commands are written to the Running Configuration file. This causes the Save icon to begin blinking when the you log on, even though you did not make any configuration changes.

Cisco Small Business 200 Series Smart Switch Administration Guide 21

Status and Statistics

RMON

RMON (Remote Networking Monitoring) enables an SNMP agent in the device to proactively monitor traffic statistics over a given period and send traps to an SNMP manager. The local SNMP agent compares actual, real-time counters against predefined thresholds and generates alarms, without the need for polling by a central SNMP management platform. This is an effective mechanism for proactive management, provided that you have set the correct thresholds relative to your network’s base line.

RMON decreases the traffic between the manager and the device since the SNMP manager does not have to poll the device frequently for information, and enables the manager to get timely status reports, since the device reports events as they occur.

With this feature, you can perform the following actions:

• View the current statistics (from the time that the counter values were cleared). You can also collect

the values of these counters over a period of time, and then view the table of collected data, where each collected set is a single line of the History tab.

• Define interesting changes in counter values, such as “reached a certain number of late collisions”

(defines the alarm), and then specify what action to perform when this event occurs (log, trap, or log and trap).

RMON Statistics

The Statistics page displays detailed information regarding packet sizes and information regarding physical layer errors. The information is displayed according to the RMON standard. An oversized packet is defined as an Ethernet frame with the following criteria:

• Packet length is greater than MRU byte size.

• Collision event has not been detected.

• Late collision event has not been detected.

• Received (Rx) error event has not been detected.

• Packet has a valid CRC.

To view RMON statistics and/or set the refresh rate:

STEP 1 Click Status and Statistics > RMON > Statistics.

STEP 2 Select the Interface for which Ethernet statistics are to be displayed.

STEP 3 Select the Refresh Rate, which is the time period that passes before the interface

statistics are refreshed.

Cisco Small Business 200 Series Smart Switch Administration Guide 22

The following statistics are displayed for the selected interface.

• Bytes Received—Octets received, including bad packets and FCS octets, but excluding framing bits.

• Drop Events—Packets dropped.

• Packets Received—Good packets received, including Multicast and Broadcast packets.

• Broadcast Packets Received—Good Broadcast packets received. This number does not include

Multicast packets.

• Multicast Packets Received—Good Multicast packets received.

• CRC & Align Errors—CRC and Align errors that have occurred.

• Undersize Packets—Undersized packets (less than 64 octets) received.

• Oversize Packets—Oversized packets (over 2000 octets) received.

• Fragments—Fragments (packets with less than 64 octets, excluding framing bits, but including FCS

octets) received.

• Jabbers—Received packets that were longer than 1632 octets. This number excludes frame bits, but

includes FCS octets that had either a bad FCS (Frame Check Sequence) with an integral number of octets (FCS Error) or a bad FCS with a non-integral octet (Alignment Error) number. A Jabber packet is defined as an Ethernet frame that satisfies the following criteria:

- Packet data length is greater than MRU.

- Packet has an invalid CRC.

- Received (Rx) Error Event has not been detected.

• Collisions—Collisions received. If Jumbo frames are enabled, the threshold of Jabber frames is

raised to the maximum size of Jumbo frames.

• Frames of 64 Bytes—Frames, containing 64 bytes that were received.

• Frames of 65 to 127 Bytes—Frames, containing 65-127 bytes that were received.

• Events Page—Configures what happens when an alarm is triggered. This can be any combination of

logs and traps.

• Alarms Page—Configures the occurrences that trigger an alarm.

To define RMON events:

STEP 1 Click Status and Statistics > RMON > Events.

This page displays previously defined events.

The fields on this page are defined by the Add RIMON Events dialog box except for the Time field.

• Time—Displays the time of the event. (This is a read-only table in the parent window and cannot be

defined).

STEP 2 Click Add.

STEP 3 Enter the parameters.

• Event Entry—Displays the event entry index number for the new entry.

• Description—Enter a name for the event. This name is used in the Add RMON Alarm page to attach

an alarm to an event.

• Notification Type—Select the type of action that results from this event. Values are:

- None—No action occurs when the alarm goes off.

- Log (Event Log Table)—Add a log entry to the Event Log table when the alarm is triggered.

- Trap (SNMP Manager and SYSLOG Server)—Send a trap to the remote log server when the

alarm goes off.

- Log and Trap—Add a log entry to the Event Log table and send a trap to the remote log server

when the alarm goes off.

• Owner—Enter the device or user that defined the event.

STEP 4 Click Apply. The RMON event is saved to the Running Configuration file.

STEP 5 Click Event Log Table to display the log of alarms that have occurred and that have

been logged (see description below).

RMON Events Logs

The Event Log Table page displays the log of events (actions) that occurred. Two types of events can be logged: Log or Log and Trap. The action in the event is performed when the event is bound to an alarm (see the Alarms page) and the conditions of the alarm have occurred.

STEP 1 Click Status and Statistics > RMON > Events.

STEP 2 Click Event Log Table.

This page displays the following fields:

• Event Entry No.—Event’s log entry number.

• Log No.—Log number (within the event).

• Log Time—Time that the log entry was entered.

• Description—Description of event that triggered the alarm.

RMON Alarms

RMON alarms provide a mechanism for setting thresholds and sampling intervals to generate exception events on counters or any other SNMP object counter maintained by the agent. Both the rising and falling thresholds must be configured in the alarm. After a rising threshold is crossed, no rising events are generated until the companion falling threshold is crossed. After a falling alarm is issued, the next alarm is issued when a rising threshold is crossed.

One or more alarms are bound to an event, which indicates the action to be taken when the alarm occurs.

Alarm counters can be monitored by either absolute values or changes (delta) in the counter values.

Status and Statistics

RMON

To enter RMON alarms:

STEP 1 Click Status and Statistics > RMON > Alarms. All previously-defined alarms are

displayed. The fields are described in the Add RMON Alarm page below. In addition to those fields, the following field appears:

• Counter Value—Displays the value of the statistic during the last sampling period.

STEP 2 Click Add.

STEP 3 Enter the parameters.

• Alarm Entry No.—Displays the alarm entry number.

• Interface—Select the type of interface for which RMON statistics are displayed.

• Counter Name—Select the MIB variable that indicates the type of occurrence measured.

• Counter Value—Number of occurrences.

• Sample Type—Select the sampling method to generate an alarm. The options are:

- Absolute—If the threshold is crossed, an alarm is generated.

- Delta—Subtracts the last sampled value from the current value. The difference in the values is

compared to the threshold. If the threshold was crossed, an alarm is generated.

• Rising Threshold—Enter the value that triggers the rising threshold alarm.

• Rising Event—Select an event to be performed when a rising event is triggered. Events are created

in the Events page.

• Falling Threshold—Enter the value that triggers the falling threshold alarm.

• Falling Event—Select an event to be performed when a falling event is triggered.

• Startup Alarm—Select the first event from which to start generation of alarms. Rising is defined by

crossing the threshold from a low-value threshold to a higher-value threshold.

- Rising Alarm—A rising value triggers the rising threshold alarm.

- Falling Alarm—A falling value triggers the falling threshold alarm.

- Rising and Falling—Both rising and falling values trigger the alarm.

• Interval—Enter the alarm interval time in seconds.

• Owner—Enter the name of the user or network management system that receives the alarm.
