This chapter describes the Enterprise Edition software features for Catalyst 1900 and Catalyst 2820 switches. It also describes the feature default settings and shows the management console main menu used to configure and manage your network.
For detailed descriptions of the hardware and baseline software features, refer to the installation and configuration guide for your switch, the Catalyst 1900 Series Installation and Configuration Guide or Catalyst 2820 Series Installation and Configuration Guide. For detailed descriptions of the command-line interface commands, refer to the Catalyst 1900 Series and Catalyst 2820 Series Command Reference (online only).
For menu-by-menu configuration and conceptual information about specific software features, such as virtual LANs (VLANs) and Fast EtherChannel, refer to the chapter documenting that feature.
The Catalyst 1900 and Catalyst 2820 switches are designed for Ethernet workgroups and individual users requiring dedicated 10-Mbps connectivity to the desktop and 100-Mbps connectivity to servers and backbones. These switches use shielded twisted-pair, unshielded twisted-pair (UTP), or fiber-optic cable. Table 1-1 and Table 1-2 describe the Catalyst 1900 and 2820 switch models.

WS-C1924C-EN | 24 10BaseT ports, 1 AUI port, | 1024 | 27 |
WS-C1912-EN | 12 10BaseT ports, 1 AUI port, | 1024 | 15 |
WS-C1912C-EN | 12 10BaseT ports, 1 AUI port, | 1024 | 15 |
You can obtain a copy of the Catalyst 1900 and 2820 switch MIB files by using File Transfer Protocol (FTP) to access the ftp.cisco.com server. To obtain a MIB file, follow these steps:
Step 1 Use FTP to access the server ftp.cisco.com, or enter www.ftp.cisco.com from your browser.
Step 2 Log in with the username anonymous.
Step 3 Enter your e-mail name when prompted for the password.
Step 4 At the ftp> prompt, change directories to /pub/mibs/supportlists/wsc1900.
Step 5 Use the command get supportlist.html or get supportlist.txt to get a list of the supported MIB files.
Step 6 Copy supported MIB files from /pub/mibs/v1.
Cisco Catalyst 1900 and 2820 Enterprise Edition Software supports these features:
The VLAN feature consists of the following components:
Extends VLANs from one Catalyst 1900 or Catalyst 2820 switch to routers and switches that are VLAN-capable. The switches support a maximum of two trunks. The Catalyst 1900 switch supports a maximum of two Fast Ethernet Inter-Switch Link (ISL) trunks. The Catalyst 2820 switch supports both ISL and Asynchronous Transfer Mode (ATM) LAN emulation (LANE) trunk connections and ATM permanent virtual connections (PVCs). | |
Allows parallel trunks to split traffic on a VLAN-by-VLAN basis between multiple trunks. | |
VLAN Trunk Protocol | Allows VLAN naming consistency and connectivity between all devices in a management domain. When new VLANs are added to a Catalyst 1900 or Catalyst 2820 switch in a management domain, the VLAN Trunk Protocol (VTP) automatically distributes the information to all the devices in the management domain. VTP advertisements are transmitted on all trunk connections, including ISL, IEEE 802.10, and ATM LANE. |
Enhances network bandwidth use by reducing unnecessary flooded traffic, including broadcast, multicast, and flooded unicast packets. This feature restricts flooded traffic to only those trunk links that the traffic must use to access the appropriate network devices. | |
Manually assigns a port to a VLAN. You need to reconfigure the switch to change the VLAN assignment to a static port. | |
Dynamic port VLAN membership | Provides the flexibility to move a connection from a port on one switch to a port on another device in the network while retaining the VLAN identity of the host. You can assign dynamic ports to a VLAN based on the source MAC address of the hosts connected to that port. |
Synchronizes the configuration of two interconnected Fast Ethernet interfaces to ensure that both interfaces are either in trunking or nontrunking mode. |
Fast EtherChannel links provide parallel bandwidth of up to 400 Mbps (in full duplex mode) between a Catalyst 1900 or Catalyst 2820 switch and another switch or host by grouping two Fast Ethernet interfaces into a single logical transmission path.
UplinkFast is an enhancement to the Spanning-Tree Protocol (STP) that provides fast convergence whenever STP picks a new root port. STP selects a new root port automatically when a link or switch fails or when STP parameters change.
The TACACS+ protocol exchanges authentication information between a network device and a centralized database. TACACS+ allows a separate access server to provide authentication for access to the switch management console. TACACS+ is used in place of a locally configured password.
You can use the Configuration File Upload and Download feature to specify switch configuration commands in an ASCII file that can be uploaded to or downloaded from a TFTP server.
When the switch powers up, it can retrieve its configuration from a TFTP server.
Table 1-3 shows the default values for Enterprise Edition software features and the management interface you use to access them.
| Feature | Default Setting | Configuration Utility |
|---|---|---|
VLAN 1 is the default Ethernet VLAN. All ports are nontrunk, static ports and belong to VLAN 1. | Virtual LAN menu or CLI | |
Off. | CLI | |
Uplink Fast | Disabled. | CLI, Switch Manager (STP), or Spanning Tree Configuration menu |
Disabled. | CLI | |
Secret password | None | CLI |
Disabled. | CLI |
The CLI is an Enterprise Edition software feature. All configuration and management options are supported through the CLI. This book lists the available CLI commands for each feature in the section detailing that feature. For detailed information on how to use the CLI, refer to the Catalyst 1900 Series and Catalyst 2820 Series Command Reference (online only).
The menu console contains options for basic configuration (as described in the switch installation guides) and for configuring VLANs. However, not all features can be accessed using its menus.
The management console menu-driven system uses the following conventions:
Refer to the Catalyst 1900 Series Installation and Configuration Guide and the Catalyst 2820 Series Installation and Configuration Guide for complete information about the menu console.

You will most often use the [N] Network Management and [V] Virtual LAN options to configure VLANs. When configuring modules, you will also use [P] Port Configuration.
If you have configured bridge groups on the switch, the menu option [V] Virtual LAN does not appear. The menu option [B] Bridge Group appears in its place.
If you have previously configured bridge groups on the switch and would like to start using VLANs, you must use menu option [S] System Menu to disable bridge group functionality. The switch then resets automatically, and the Main Menu displays the [V] Virtual LAN menu option.
The Catalyst 1900 or Catalyst 2820 web console offers a convenient way to access the switch management interface across an Internet connection. Using the web console, you can set the parameters for the switch configuration.
The web console displays an action bar at the top of the display window. Using the buttons on the action bar, you can navigate through the web console pages, access additional menus, and change the operational parameters. Fast EtherChannel parameters are available from the Port Management Page, and the UpLink Fast parameters are accessed from the Spanning Tree Management Page. Complete information about the web console is documented in the Catalyst 1900 Series Installation and Configuration Guide and the Catalyst 2820 Series Installation and Configuration Guide.
Your PC must have an Internet browser installed and an IP address assigned to view the switch web console. For best results with the web console, one of the following browser versions is required:
The web console offers Telnet service for accessing the menu console and the switch CLI. If the switch has an IP address, when you click Telnet, the Menu Console Logon Screen displays. You can enter [M] Menus to access the Menu System or [K] Command Line to access the CLI.
The web console is fully documented in the Catalyst 1900 Series Installation and Configuration Guide and the Catalyst 2820 Series Installation and Configuration Guide.
