Catalyst 3750-X and 3560-X Switch Software Configuration Guide
OL-21521-01
Chapter 1 Overview Features
• IGMP snooping querier support to configure switch to generate periodic IGMP General Query
messages
• IIGMP Helper to allow the switch to forward a host request to join a multicast stream to a specific
IP destination address
• Multicast Listener Discovery (MLD) snooping to enable efficient distribution of IP Version 6 (IPv6)
multicast data to clients and routers in a switched network.
• Multicast VLAN registration (MVR) to continuously send multicast streams in a multicast VLAN
while isolating the streams from subscriber VLANs for bandwidth and security reasons
• IGMP filtering for controlling the set of multicast groups to which hosts on a switch port can belong
• IGMP throttling for configuring the action when the maximum number of entries is in the IGMP
forwarding table
• IGMP leave timer for configuring the leave latency for the network
• Switch Database Management (SDM) templates for allocating system resources to maximize
support for user-selected features
• Web Cache Communication Protocol (WCCP) for redirecting traffic to wide-area application
engines, for enabling content requests to be fulfilled locally, and for localizing web-traffic patterns
in the network (requires the IP services feature set)
• Configurable small-frame arrival threshold to prevent storm control when small frames (64 bytes or
less) arrive on an interface at a specified rate (the threshold)
• Flex Link Multicast Fast Convergence to reduce the multicast traffic convergence time after a Flex
Link failure
• Support for IEEE 802.11n-enabled access points and support for powered devices that draw more
than 15.4 watts
• RADIUS server load balancing to allow access and authentication requests to be distributed evenly
across a server group.
• Cisco Medianet to enable intelligent services in the network infrastructure for a wide variety of
video applications. One of the services of Medianet is auto provisioning for Cisco Digital Media
Players and Cisco IP Video Surveillance cameras through Auto Smartports.
• Support for QoS marking of CPU-generated traffic and queue CPU-generated traffic on the egress
network ports.
Management Options
• An embedded device manager—The device manager is a GUI that is integrated in the universal
software image. You use it to configure and to monitor a single switch. For information about starting
the device manager, see the getting started guide. For more information about the device manager, see
the switch online help.
• Network Assistant—Network Assistant is a network management application that can be
downloaded from Cisco.com. You use it to manage a single switch, a cluster of switches, or a
community of devices. For more information about Network Assistant, see Getting Started with
Cisco Network Assistant, available on Cisco.com.
• CLI—The Cisco IOS software supports desktop- and multilayer-switching features. You can access
the CLI by connecting your management station directly to the switch console port, by connecting
your PC directly to the Ethernet management port, or by using Telnet from a remote management
