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 older versions of Internet Explorer, you cannot directly use
an IPv6 address to access the device. You can, however, use the DNS (Domain Name System) server to create a domain name that contains the IPv6 address, and then use that domain name in the address bar in place of the IPv6 address.
• If you have multiple IPv6 interfaces on your management station, use the
IPv6 global address instead of the IPv6 link local address to access the device from your browser.
Cisco Small Business 200 Series Smart Switch Administration Guide 1
Getting Started
Starting the Web-based Configuration Utility
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.
Logging In
1
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 the Setting Password
Complexity Rules section of the Configuring Security chapter.
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, refer to the Upgrade/Backup Firmware/Language section.

Starting the Web-based Configuration Utility
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.
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 appears:
• The first time 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 will remove 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.
When you click Save, the Copy/Save Configuration page appears. Save the Running Configuration file by copying it to the Startup Configuration file. After this save, the red X icon and the Save application link are no longer displayed.
To logout, click Logout in the top right corner of any page. The system logs out of the device.
When a timeout occurs or you intentionally log out of the system, a message appears and the Login page appears, with a message indicating the logged-out state. After you log in, the application returns to the initial page.
The initial page displayed depends on the “Do not show this page on startup” option in the Getting Started page. If you did not select this option, the initial page is the Getting Started page. If you did select this option, the initial page is the System Summary page.

Managing RMON

Managing RMON
RMON (Remote Networking Monitoring) is an SNMP specification that 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 the correct thresholds set relative to your network’s base line.
RMON decreases the traffic between the manager and the device because the SNMP manager does not have to poll the device frequently for information, and enables the manager to get timely status reports, because the device reports events as they occur.
With this feature, you can perform the following actions:
2
• View the current statistics (since 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).
Viewing RMON Statistics
The Statistics page displays detailed information regarding packet sizes and information regarding physical layer errors. The information displayed is 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.

Status and Statistics
Managing RMON
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, the time period that passes before the interface
statistics are refreshed.
The statistics are displayed for the selected interface.
• Bytes Received—Number of octets received, including bad packets and
FCS octets, but excluding framing bits.
• Drop Events—Number of packets dropped.
• Packets Received—Number of good packets received, including Multicast
and Broadcast packets.
• Broadcast Packets Received—Number of good Broadcast packets
received. This number does not include Multicast packets.
• Multicast Packets Received—Number of good Multicast packets received.
• CRC & Align Errors—Number of CRC and Align errors that have occurred.
• Undersize Packets—Number of undersized packets (less than 64 octets)
received.
• Oversize Packets—Number of oversized packets (over 2000 octets)
received.
• Fragments—Number of fragments (packets with less than 64 octets,
excluding framing bits, but including FCS octets) received.
• Jabbers—Total number 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.
