Page 180: Spanning Tree Algorithm Configuration
Configuring the Switch Spanning Tree Algorithm Configuration The Spanning Tree Algorithm (STA) can be used to detect and disable network loops, and to provide backup links between switches, bridges or routers. This allows the switch to interact with other bridging devices (that is, an STA-compliant switch, bridge or router) in your network to ensure that only one route exists between any two stations on the network, and provide backup links which automatically take over when a primary link goes down.
Page 181 Spanning Tree Algorithm Configuration isolate some of the group members. MSTP (which is based on RSTP for fast convergence) is designed to support independent spanning trees based on VLAN groups. Using multiple spanning trees can provide multiple forwarding paths and enable load balancing.

Page 246: Multicast Filtering
Configuring the Switch Multicast Filtering Multicasting is used to support real-time Unicast applications such as videoconferencing or Flow 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.
Page 247: Layer 2 Igmp (Snooping And Query)
Multicast Filtering Layer 2 IGMP (Snooping and Query) IGMP Snooping and Query — If multicast routing is not supported on other switches in your network, you can use IGMP Snooping and IGMP Query (page 3-204) to monitor IGMP service requests passing between multicast clients and servers, and dynamically configure the switch ports which need to forward multicast traffic.
Page 248: Configuring Igmp Snooping And Query Parameters
Configuring the Switch Static IGMP Host Interface — For multicast applications that you need to control more carefully, you can manually assign a multicast service to specific interfaces on the switch (page 3-210).

Page 251: Displaying Interfaces Attached To A Multicast Router
Multicast Filtering Displaying Interfaces Attached to a Multicast Router Multicast routers that are attached to ports on the switch use information obtained from IGMP, along with a multicast routing protocol such as DVMRP or PIM, to support IP multicasting across the Internet. These routers may be dynamically discovered by the switch or statically assigned to an interface on the switch.
Page 252: Specifying Static Interfaces For A Multicast Router
Configuring the Switch Specifying Static Interfaces for 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 the interface (and a specified VLAN) to join all the current multicast groups supported by the attached router.

You can classify traffic based on access lists, IP Precedence or DSCP values, or VLANs. Using access lists allows you select traffic based on Layer 2, Layer 3, or Layer 4 information contained in each packet.
Page 514: Class-Map
Command Line Interface Notes: 1. You can configure up to 16 rules per Class Map. You can also include multiple classes in a Policy Map. You should create a Class Map (page 4-244) before creating a Policy Map (page 4-246). Otherwise, you will not be able to specify a Class Map with the class command (page 4-246) after entering Policy-Map Configuration mode.
Page 515: Match
Quality of Service Commands match This command defines the criteria used to classify traffic. Use the no form to delete the matching criteria. Syntax [no] match {access-list acl-name | ip dscp dscp | ip precedence ip-precedence | vlan vlan} • acl-name - Name of the access control list. Any type of ACL can be specified, including standard or extended IP ACLs and MAC ACLs.
Page 516: Policy-Map
Command Line Interface policy-map This command creates a policy map that can be attached to multiple interfaces, and enters Policy Map configuration mode. Use the no form to delete a policy map and return to Global configuration mode. Syntax [no] policy-map policy-map-name policy-map-name - Name of the policy map.
Page 517: Set
Quality of Service Commands Command Mode Policy Map Configuration Command Usage • Use the policy-map command to specify a policy map and enter Policy Map configuration mode. Then use the class command to enter Policy Map Class configuration mode. And finally, use the set and police commands to specify the match criteria, where the: - set command classifies the service that an IP packet will receive.
Page 518: Police
Command Line Interface Example This example creates a policy called “rd_policy,” uses the class command to specify the previously defined “rd_class,” uses the set command to classify the service that incoming packets will receive, and then uses the police command to limit the average bandwidth to 100,000 Kbps, the burst rate to 1522 bytes, and configure the response to drop any violating packets.

Page 522: Multicast Filtering Commands
Command Line Interface Multicast Filtering Commands 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 a 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.

Page 533: Mvr (Interface Configuration)
Multicast Filtering Commands IGMPv1/v2 multicast report messages or IGMPv2 leave messages sent by IGMPv1/v2 hosts are supported by the current MVR standard. • IGMP snooping and MVR share a maximum number of 255 groups. Any multicast streams received in excess of this limitation will be flooded to all ports in the associated VLAN.
Page 534: Mvr Immediate
Command Line Interface • One or more interfaces may be configured as MVR source ports. A source port is able to both receive and send data for multicast groups which it has joined through IGMP snooping or which have been statically assigned using the group keyword.
Page 535: Show Mvr
Multicast Filtering Commands response to determine if there are any remaining subscribers for that multicast group before removing the port from the group list. - Using immediate leave can speed up leave latency, but should only be enabled on a port attached to one multicast subscriber to avoid disrupting services to other group members attached to the same interface.

Page 549: Glossary
Glossary Access Control List (ACL) ACLs can limit network traffic and restrict access to certain users or devices by checking each packet for certain IP or MAC (i.e., Layer 2) information. Boot Protocol (BOOTP) BOOTP used to provide bootup information for network devices, including IP address information, the address of the TFTP server that contains the devices system files, and the name of the boot file.
Page 550 Glossary 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...

IGMP Snooping Listening to IGMP Query and IGMP Report packets transferred between IP Multicast Routers and IP Multicast host groups to identify IP Multicast group members. IGMP Query On each subnetwork, one IGMP-capable device will act as the querier —...
Page 552 Glossary MD5 Message-Digest Algorithm An algorithm that is used to create digital signatures. It is intended for use with 32 bit machines and is safer than the MD4 algorithm, which has been broken. MD5 is a one-way hash function, meaning that it takes a message and converts it into a fixed string of digits, also called a message digest.
Page 553 Glossary Remote Monitoring (RMON) RMON provides comprehensive network monitoring capabilities. It eliminates the polling required in standard SNMP, and can set alarms on a variety of traffic conditions, including specific error types. Rapid Spanning Tree Protocol (RSTP) RSTP reduces the convergence time for network topology changes to about 10% of that required by the older IEEE 802.1D STP standard.
Page 554 Glossary Trivial File Transfer Protocol (TFTP) A TCP/IP protocol commonly used for software downloads. User Datagram Protocol (UDP) provides a datagram mode for packet-switched communications. It uses IP as the underlying transport mechanism to provide access to IP-like services. UDP packets are delivered just like IP packets –...
