Rate Limiting – This feature controls the maximum rate for traffic received on an interface. Rate limiting is configured on interfaces at the edge of a network to limit traffic into the network.
Page 32 Introduction Rapid Spanning Tree Protocol (RSTP, IEEE 802.1w) – This protocol reduces the convergence time for network topology changes to 3 to 5 seconds, compared to 30 seconds or more for the older IEEE 802.1D STP standard. It is intended as a complete replacement for STP, but can still interoperate with switches running the older standard by automatically reconfiguring ports to STP-compliant mode if they detect STP protocol messages from attached devices.
Page 33 Description of Software Features or VLAN lists. Using access lists allows you select traffic based on Layer 2, Layer 3, or Layer 4 information contained in each packet. Based on network policies, different kinds of traffic can be marked for different kinds of forwarding. Multicast Filtering –...

Configuring the Switch Configuring Global Settings Global settings apply to the entire switch. Command Usage • Spanning Tree Protocol Uses RSTP for the internal state machine, but sends only 802.1D BPDUs. This creates one spanning tree instance for the entire network. If multiple VLANs are implemented on a network, the path between specific VLAN members may be inadvertently disabled to prevent network loops, thus isolating group members.

Page 256: Displaying Interfaces Attached To A Multicast Router
Configuring the Switch is determined by the IGMP Query Report Delay (see “Configuring IGMP Snooping and Query Parameters” on page 3-207). • If immediate leave is enabled, the switch assumes that only one host is connected to the interface. Therefore, immediate leave should only be enabled on an interface if it is connected to only one IGMP-enabled device, either a service host or a neighbor running IGMP snooping.
Page 257: Specifying Static Interfaces For A Multicast Router
Multicast Filtering support IP multicasting across the Internet. These routers may be dynamically discovered by the switch or statically assigned to an interface on the switch. 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.

IP Source Guard Commands - If there is an entry with same VLAN ID and MAC address, and the type of entry is static IP source guard binding, then the new entry will replace the old one. - If there is an entry with same VLAN ID and MAC address, and the type of the entry is dynamic DHCP snooping binding, then the new entry will replace the old one and the entry type will be changed to static IP source guard binding.
Page 598: Switch Cluster Commands
Command Line Interface Switch Cluster Commands Switch Clustering is a method of grouping switches together to enable centralized management through a single unit. A switch cluster has a “Commander” unit that is used to manage all other “Member” switches in the cluster. The management station uses Telnet to communicate directly with the Commander throught its IP address, and the Commander manages Member switches using cluster “internal”...

Page 611: 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) used to provide bootup information for network devices, including IP BOOTP is address information, the address of the TFTP server that contains the devices system files, and the name of the boot file.
Page 612 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...
Page 613 Glossary 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 — that is, the device that asks all hosts to report on the IP multicast groups they wish to join or to which they already belong.
Page 614 Glossary Multicast Switching A process whereby the switch filters incoming multicast frames for services for which no attached host has registered, or forwards them to all ports contained within the designated multicast VLAN group. Network Time Protocol (NTP) NTP provides the mechanisms to synchronize time across the network. The time servers operate in a hierarchical-master-slave configuration in order to synchronize local clocks within the subnet and to national time standards via wire or radio.
Page 615 Glossary Secure Shell (SSH) A secure replacement for remote access functions, including Telnet. SSH can authenticate users with a cryptographic key, and encrypt data connections between management clients and the switch. Simple Network Management Protocol (SNMP) The application protocol in the Internet suite of protocols which offers network management services.
Page 616 Glossary Virtual LAN (VLAN) A Virtual LAN is a collection of network nodes that share the same collision domain regardless of their physical location or connection point in the network. A VLAN serves as a logical workgroup with no physical barriers, and allows users to share information and resources as though located on the same LAN.
