These routers may be dynamically discovered by the switch or statically assigned to an interface on the switch. Displaying Interfaces Attached to a Multicast Router You can use the Multicast Router Port Information page to display the ports on this switch attached to a neighboring multicast router/switch for each VLAN ID. Command Attributes · · VLAN ID ­ ID of configured VLAN (1-4094). Multicast Router List ­ Multicast routers dynamically discovered by this switch or those that are statically assigned to an interface on this switch. Web ­ Click IGMP Snooping, Multicast Router Port Information. Select the required VLAN ID from the scroll-down list to display the associated multicast routers. 2-151 CONFIGURING THE SWITCH CLI ­ This example shows that Port 11 has been statically configured as a port attached to a multicast router. Console#show ip igmp snooping mrouter vlan 1 VLAN M'cast Router Port Type ---- ------------------ ------1 Eth 1/11 Static 3-214 Specifying Interfaces Attached to a Multicast Router Depending on your network connections, IGMP snooping may not always be able to locate the IGMP querier. Therefore, if the IGMP querier is a known multicast router/switch connected over the network to an interface (port or trunk) on your switch, you can manually configure that interface to join all the current multicast groups. 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. 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. For example: Console(config)#interface vlan 1 Console(config-if)#ip address 10. 1. 0. 1 255. 255. 255. 0 Console(config-if)#exit Console(config)#ip default-gateway 10. 1. 0. 254 If your corporate network is connected to another network outside your office or to the Internet, you need to apply for a registered IP address. 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. 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). 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. [. . . ]
