Management Protocol). This SNMP agent permits the switch to be managed from any system in the network using management software, such as such as SMC’s free EliteView software. The CLI program can be accessed by a direct connection to the RS-232 serial console port on the switch, or remotely by a Telnet connection over the network.
Page 16 WITCH ANAGEMENT The switch’s CLI configuration program, Web interface, and SNMP agent allow you to perform the following management functions: • Set user names and passwords for up to 16 users • Set an IP interface for a management VLAN •...
Page 17: Required Connections
ONNECTING TO THE WITCH Required Connections The switch provides an RS-232 serial port that enables a connection to a PC or terminal for monitoring and configuring the switch. A null-modem console cable is provided with the switch. Attach a VT100-compatible terminal, or a PC running a terminal emulation program to the switch.
Page 18: Remote Connections
WITCH ANAGEMENT 4. Once you have set up the terminal correctly, the console login screen will be displayed. Note: Refer to “Line Commands” on page 3-57 for a complete description of console configuration options. For a description of how to use the CLI, see “Using the Command Line Interface”...
Page 19: Basic Configuration
ASIC ONFIGURATION Basic Configuration Console Connection The CLI program provides two different command levels — normal access level (Normal Exec) and privileged access level (Privileged Exec). The commands available at the Normal Exec level are a limited subset of those available at the Privileged Exec level and allow you to only display information and use basic utilities.
Page 20: Setting An Ip Address
WITCH ANAGEMENT Passwords can consist of up to eight alphanumeric characters and are case sensitive. To prevent unauthorized access to the switch, set the passwords as follows: 1. Open the console interface with the default user name and password “admin” to access the Privileged Exec level. 2.
Page 21: Manual Configuration
ASIC ONFIGURATION Note: Only one VLAN interface can be assigned an IP address (the default is VLAN 1). This defines the management VLAN, the only VLAN through which you can gain management access to the switch. If you assign an IP address to any other VLAN, the new IP address overrides the original IP address and this becomes the new management VLAN.

Page 40: Setting The Ip Address
ONFIGURING THE WITCH Setting the IP Address An IP address may be used for management access to the switch over your network. By default, the switch uses DHCP to assign IP settings to VLAN 1 on the switch. If you wish to manually configure IP settings, you need to change the switch’s user-specified defaults (IP address 0.0.0.0 and netmask 255.0.0.0) to values that are compatible with your network.
Page 41 ASIC ONFIGURATION • Subnet Mask – This mask identifies the host address bits used for routing to specific subnets. • Gateway IP Address – IP address of the gateway router between this device and management stations that exist on other network segments. •...
Page 42 ONFIGURING THE WITCH Web – Click System/IP. Specify the Management VLAN, set the IP Address Mode to DHCP or BOOTP. Then click “Apply” to save your changes. The switch will broadcast a request for IP configuration settings on the next power reset. Otherwise, you can click “Restart DHCP” to immediately request a new address.

Page 58: Setting Broadcast Storm Thresholds
ONFIGURING THE WITCH Setting Broadcast Storm Thresholds Broadcast storms may occur when a device on your network is malfunctioning, or if application programs are not well designed or properly configured. If there is too much broadcast traffic on your network, performance can be severely degraded or everything can come to complete halt.

Page 64 ONFIGURING THE WITCH The following global attributes can be configured: • Spanning Tree State – Enable/disabled this switch to participate in a STA-compliant network. • Priority – Bridge priority is used in selecting the root device, root port, and designated port. The device with the highest priority becomes the STA root device.
Page 65: Displaying The Current Global Settings For Sta
PANNING ROTOCOL ONFIGURATION • Forward Delay – The maximum time (in seconds) the root device will wait before changing states (i.e., listening to learning to forwarding).

Page 81: Configuring Vlan Behavior For Interfaces
VLAN C ONFIGURATION Configuring VLAN Behavior for Interfaces You can configure VLAN behavior for specific interfaces, including the default VLAN identifier (PVID), accepted frame types, ingress filtering, GVRP status, and GARP timers. Command Usage • GVRP – GARP VLAN Registration Protocol defines a way for switches to exchange VLAN information in order to automatically register VLAN members on interfaces across the network.
Page 82 ONFIGURING THE WITCH • GVRP Status – Enables/disables GVRP for the interface. GVRP must be globally enabled for the switch before this setting can take effect. (See “Displaying Bridge Extension Capabilities” on page 2-20.) When disabled, any GVRP packets received on this port will be discarded and no GVRP registrations will be propagated from other ports.

Page 88: Setting The Service Weight For Traffic Classes
ONFIGURING THE WITCH Setting the Service Weight for Traffic Classes This switch uses the Weighted Round Robin (WRR) algorithm to determine the frequency at which it services each priority queue. As described in “Mapping CoS Values to Egress Queues” on page 2-55, the traffic classes are mapped to one of the four egress queues provided for each port.
Page 89: Mapping Layer 3/4 Priorities To Cos Values
LASS OF ERVICE ONFIGURATION Mapping Layer 3/4 Priorities to CoS Values This switch supports a common method of prioritizing layer 3/4 traffic to meet application requirements. Traffic priorities can be specified in the IP header of a frame, using the priority bits in the Type of Service (ToS) octet. The ToS octet may contain three bits for IP Precedence or six bits for Differentiated Services Code Point (DSCP) service.
Page 90: Mapping Ip Precedence
ONFIGURING THE WITCH CLI – The following example globally enables IP Precedence service on the switch. Console(config)#map ip precedence 3-127 Console# Mapping IP Precedence The Type of Service (ToS) octet in the IPv4 header includes three precedence bits defining eight different priority levels ranging from highest priority for network control packets to lowest priority for routine traffic.

ULTICAST ONFIGURATION CLI – This example adds a trap manager and enables authentication traps. 3-46 Console(config)#snmp-server host 10.1.19.23 batman 3-48 Console(config)#snmp-server enable traps authentication Multicast Configuration Multicasting is used to support real-time applications such as video conferencing or streaming audio. A multicast server does not have to establish a separate connection with each client.
Page 100: Configuring Igmp Parameters
ONFIGURING THE WITCH The purpose of IP multicast filtering is to optimize a switched network’s performance, so multicast packets will only be forwarded to those ports containing multicast group hosts or multicast routers/switches, instead of flooding traffic to all ports in the subnet (VLAN). Configuring IGMP Parameters You can configure the switch to forward multicast traffic intelligently.
Page 101 ULTICAST ONFIGURATION Command Attributes • IGMP Status — When enabled, the switch will monitor network traffic to determine which hosts want to receive multicast traffic. This is also referred to as IGMP Snooping. (Default: Disabled) • Act as IGMP Querier — When enabled, the switch can serve as the Querier, which is responsible for asking hosts if they want to receive multicast traffic.
