7. Before enabling VLANs for the switch you must first assign each port to the VLAN group s in which it will participate By default all ports are assigned to VLAN 1 as untagged ports Add a port as a tagged port if you want it to carry traffic for one or more VLANs and any intermediate network devices or the host at the other end of the connection supports VLANs Then assign ports on the other VLAN aware network devices along the path that will carry this traffic to the same VLAN s either manually or dynamically using GVRP However if you want a port on this switch to participate in one or more VLANs but none of the intermediate network devices nor the host at the other end of the connection supports VLANs then you should add this port to the VLAN as an untagged port Note VLAN tagged frames can pass through VLAN aware or VLAN unaware network interconnection devices but the VLAN tags should be stripped off before passing it on to any end node host that does not support VLAN tagging VLAN Classification When the switch receives a frame it classifies the frame in one of two ways If the frame is untagged the switch assigns the frame to an associated VLAN based on the PVID of the receiving port But if the frame is tagged the switch uses the tagged VLAN ID to identify the port broadcast domain of the frame 2 71 CONFIGURING THE SWITCH 2 72 Port Overlapping Port overlapping can be used to allow access to commonly share

9. Command Mode Global Configuration Command Usage e You can create a list of up to 16 IP addresses or IP address groups that are allowed access to the switch via SNMP management software e Address bitmasks are similar to a subnet mask containing four decimal integers from 0 to 255 each separated by a period The binary mask uses 1 bits to indicate match and 0 bits to indicate ignore 3 70 SNMP COMMANDS e If the IP is the address of a single management station the bitmask should be set to 255 255 255 255 Otherwise the IP address group is specified by the bitmask e The default setting is null which allows all IP groups SNMP access to the switch If one IP address is configured the IP filtering is enabled and only addresses in the IP group will have SNMP access e IP filtering does not affect management access to the switch using the Web interface or Telnet Example The following example enables SNMP IP filtering on the switch and allows SNMP management access to client IP 10 1 2 3 and client IP group 10 1 3 0 to 10 1 3 255 Console config snmp ip filter 10 1 2 3 255 255 255 255 Console config snmp ip filter 10 1 3 0 255 255 255 0 Console config Related Commands show snmp 8 71 show snmp Use this command to check the status of SNMP communications Default Setting None Command Mode Normal Exec Privileged Exec 3 71 COMMAND LINE INTERFACE 3 72 Command

NetBEUI By using IEEE 802 1Q compliant VLANs you can organize any group of network nodes into separate broadcast domains thus confining broadcast traffic to the originating group This also provides a more secure and cleaner network environment An IEEE 802 1Q VLAN is a group of ports that can be located anywhere in the network but communicate as though they belong to the same physical segment VLANs help to simplify network management by allowing you to move devices to a new VLAN without having to change any physical connections VLANs can be easily organized to reflect departmental groups such as Marketing or R amp D usage groups such as e mail or multicast groups used for multimedia applications such as videoconferencing VLANs provide greater network efficiency by reducing broadcast traffic and allow you to make network changes without having to update IP addresses or IP subnets VLANs inherently provide a high level of network security since traffic must pass through a configured Layer 3 link to reach a different VLAN e Up to 255 VLANs based on the IEEE 802 1Q standard e Distributed VLAN learning across multiple switches using explicit or implicit tagging and GVRP protocol e Port overlapping allowing a port to participate in multiple VLANs VLAN CONFIGURATION e End stations can belong to multiple VLANs e Passing traffic between VLAN aware and VLAN unaware devices e Priority tagging Assigning Ports to VLANs

80. FIGURATION 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 It merely broadcasts its service to the network and any hosts that want to receive the multicast register with their local multicast switch router Although this approach reduces the network overhead required by a multicast server the broadcast traffic must be carefully pruned at every multicast switch router it passes through to ensure that traffic is only passed on the hosts which subscribed to this service This switch uses IGMP Internet Group Management Protocol to query for any attached hosts that want to receive a specific multicast service It identifies the ports containing hosts requesting to join the service and sends data out to those ports only It then propagates the service request up to any neighboring multicast switch router to ensure that it will continue to receive the multicast service This procedure is called multicast filtering 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 intelligen
