[. . . ] This can ensure that multicast traffic is passed to all the appropriate interfaces within the switch. 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. 2-152 MULTICAST FILTERING Web ­ Click IGMP Snooping, Static Multicast Router Port Configuration. Specify the interfaces attached to a multicast router, indicate the VLAN which will forward all the corresponding multicast traffic, and then click Add. After you have completed adding interfaces to the list, click Apply. CLI ­ This example configures port 11 as a multicast router port within VLAN 1. Console(config)#ip igmp snooping vlan 1 mrouter ethernet 1/11 Console(config)#exit Console#show ip igmp snooping mrouter vlan 1 VLAN M'cast Router Port Type ---- ------------------ ------1 Eth 1/11 Static 3-213 3-214 Displaying Port Members of Multicast Services You can display the port members associated with a specified VLAN and multicast IP address. 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. Select the VLAN ID and multicast IP address. 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. Member ports Type ---- --------------- ------------ ------1 224. 0. 0. 12 Eth1/12 USER 1 224. 1. 2. 3 Eth1/12 IGMP Console# 3-208 Adding Multicast Addresses to VLANs Multicast filtering can be dynamically configured using IGMP Snooping and IGMP Query messages as described in "Configuring IGMP Snooping Parameters" on page 2-148. For certain applications that require tighter control, you may need to statically configure a multicast service on the switch. However, if you are attached to an isolated network, then you can use any IP address that matches the network segment to which you are attached. 3-2 ENTERING COMMANDS After you configure the switch with an IP address, you can open a Telnet session by performing these steps. From the remote host, enter the Telnet command and the IP address of the device you want to access. At the prompt, enter the user name and system password. The CLI will display the "Vty-0#" prompt for the administrator to show that you are using privileged access mode (i. e. , Privileged Exec), or "Vty-0>" for the guest to show that you are using normal access mode (i. e. , Normal Exec). Enter the necessary commands to complete your desired tasks. When finished, exit the session with the "quit" or "exit" command. After entering the Telnet command, the login screen displays: Username: admin Password: CLI session with the SMC6724L3 is opened. Console# Note: You can open up to four sessions to the device via Telnet. Entering Commands This section describes how to enter CLI commands. Keywords and Arguments A CLI command is a series of keywords and arguments. Keywords identify a command, and arguments specify configuration parameters. For example, in the command "show interfaces status ethernet 1/5, " show 3-3 COMMAND LINE INTERFACE interfaces and status are keywords, ethernet is an argument that specifies the interface type, and 1/5 specifies the unit/port. You can enter commands as follows: · · To enter a simple command, enter the command keyword. [. . . ] Data is transmitted from the queues using weighted round-robin service to enforce priority service and prevent blockage of lower-level queues. Priority may be set according to the port default, the packet's priority bit (in the VLAN tag), TCP/UDP port number, IP Precedence bit, or DSCP priority bit. Differentiated Services Code Point Service (DSCP) DSCP uses a six-bit tag to provide for up to 64 different forwarding behaviors. Based on network policies, different kinds of traffic can be marked for different kinds of forwarding. The DSCP bits are mapped to the Class of Service categories, and then into the output queues. Domain Name Service (DNS) A system used for translating host names for network nodes into IP addresses. Dynamic Host Control Protocol (DHCP) Provides a framework for passing configuration information to hosts on a TCP/IP network. [. . . ]
