Command Attributes · · · VLAN ID ­ Selects the VLAN in which to display port members. Multicast IP Address ­ The IP address for a specific multicast service Multicast Group Port List ­ Ports propagating a multicast service; i. e. , ports that belong to the indicated VLAN group. 2-153 CONFIGURING THE SWITCH Web ­ Click IGMP Snooping , IP Multicast Registration Table. The switch will display all the ports that are propagating this multicast service. CLI ­ This example displays all the known multicast services supported on VLAN 1, along with the ports propagating the corresponding services. The type field shows if this entry was learned dynamically or was statically configured. Console#show mac-address-table multicast vlan 1 VLAN M'cast IP addr.

For certain applications that require tighter control, you may need to statically configure a multicast service on the switch. First add all the ports attached to participating hosts to a common VLAN, and then assign the multicast service to that VLAN group. 2-154 MULTICAST FILTERING Command Usage · · Static multicast addresses are never aged out. When a multicast address is assigned to specific VLAN, the corresponding traffic can only be forwarded to ports within that VLAN. Command Attributes · · · · Interface ­ Activates the Port or Trunk scroll down list. VLAN ID ­ Selects the VLAN to propagate all multicast traffic coming from the attached multicast router/switch. Port or Trunk ­ Specifies the interface attached to a multicast router. Web ­ Click IGMP Snooping, IGMP Member Port Table. Specify the interface attached to a multicast service (via an IGMP-enabled switch or multicast router), indicate the VLAN that will propagate the multicast service, specify the multicast IP address, and then click Add. After you have completed adding ports to the member list, click Apply. 2-155 CONFIGURING THE SWITCH CLI ­ This example assigns a multicast address to VLAN 1, and then displays all the known multicast services supported on VLAN 1.

Using the Command Line Interface Accessing the CLI When accessing the management interface for the switch over a direct connection to the server's console port, or via a Telnet connection, the switch can be managed by entering command keywords and parameters at the prompt. Using the switch's command-line interface (CLI) is very similar to entering commands on a UNIX system. Console Connection To access the switch through the console port, perform these steps: 1. (The default user names are "admin" and "guest" with corresponding passwords of "admin" and "guest. ") When the administrator user name and password is entered, the CLI displays the "Console#" prompt and enters privileged access mode (i. e. , Privileged Exec). But when the guest user name and password is entered, the CLI displays the "Console>" prompt and enters normal access mode (i. e. , Normal Exec). When finished, exit the session with the "quit" or "exit" command. 3-1 COMMAND LINE INTERFACE After connecting to the system through the console port, the login screen displays: User Access Verification Username: admin Password: CLI session with the SMC6724AL2 is opened. Console# Telnet Connection Telnet operates over the IP transport protocol. In this environment, your management station and any network device you want to manage over the network must have a valid IP address. Valid IP addresses consist of four numbers, 0 to 255, separated by periods. For example, the IP address assigned to this switch, 10. 1. 0. 1, consists of a network portion (10. 1. 0) and a host portion (1). To access the switch through a Telnet session, you must first set the IP address for the switch, and set the default gateway if you are managing the switch from a different IP subnet. [. . . ] DHCP is based on the Bootstrap Protocol (BOOTP), adding the capability of automatic allocation of reusable network addresses and additional configuration options. Glossary-1 GLOSSARY Extensible Authentication Protocol over LAN (EAPOL) EAPOL is a client authentication protocol used by this switch to verify the network access rights for any device that is plugged into the switch. A username and password is requested by the switch, and then passed to an authentication server (e. g. , RADIUS) for verification. EAPOL is implemented as part of the IEEE 802. 1x Port Authentication standard. GARP VLAN Registration Protocol (GVRP) Defines a way for switches to exchange VLAN information in order to register necessary VLAN members on ports along the Spanning Tree so that VLANs defined in each switch can work automatically over a Spanning Tree network. Generic Attribute Registration Protocol (GARP) GARP is a protocol that can be used by endstations and switches to register and propagate multicast group membership information in a switched environment so that multicast data frames are propagated only to those parts of a switched LAN containing registered endstations. Formerly called Group Address Registration Protocol. Generic Multicast Registration Protocol (GMRP) GMRP allows network devices to register endstations with multicast groups. [. . . ]
