Chapter 1 Overview
Features
Performance Features
The switch ships with these performance features:
• Cisco EnergyWise to manage the energy usage of power over Ethernet (PoE) entities
• Autosensing of port speed and autonegotiation of duplex mode on all switch ports for optimizing
bandwidth
• Automatic-medium-dependent interface crossover (auto-MDIX) capability on 10/100- and
10/100/1000-Mb/s interfaces and on 10/100/1000 BASE-TX SFP module interfaces that enables the
interface to automatically detect the required cable connection type (straight-through or crossover)
and to configure the connection appropriately
• Support for the maximum packet size or maximum transmission unit (MTU) size for these types of
frames:
– Up to 9216 bytes for routed frames
– Up to 9216 bytes for frames that are bridged in hardware and software through Gigabit Ethernet
ports and 10-Gigabit Ethernet ports
• IEEE 802.3x flow control on all ports (the switch does not send pause frames)
• Up to 64 Gb/s of throughput in a switch stack
• EtherChannel for enhanced fault tolerance and for providing up to 8 Gb/s (Gigabit EtherChannel)
or 80
Gb/s (10-Gigabit EtherChannel) full-duplex bandwidth among switches, routers, and servers
• Port Aggregation Protocol (PAgP) and Link Aggregation Control Protocol (LACP) for automatic
creation of EtherChannel links
• Support for up to 64 EtherChannels
• Forwarding of Layer 2 and Layer 3 packets at Gigabit line rate
• Forwarding of Layer 2 and Layer 3 packets at Gigabit line rate across the switches in the stack
• Per-port storm control for preventing broadcast, multicast, and unicast storms
• Port blocking on forwarding unknown Layer 2 unknown unicast, multicast, and bridged broadcast
traffic
• Cisco Group Management Protocol (CGMP) server support and Internet Group Management
Protocol (IGMP) snooping for IGMP Versions
1, 2, and 3:
– (For CGMP devices) CGMP for limiting multicast traffic to specified end stations and reducing
overall network traffic
– (For IGMP devices) IGMP snooping for efficiently forwarding multimedia and multicast traffic
• IGMP report suppression for sending only one IGMP report per multicast router query to the
multicast devices (supported only for IGMPv1 or IGMPv2 queries)
• IGMP snooping querier support to configure switch to generate periodic IGMP General Query
messages
• IGMP 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
