Performance Features
Cisco EnergyWise manages the energy usage of end points including power over Ethernet (PoE)
devices and non-Cisco devices. For information, see the Cisco EnergyWise Configuration Guide.
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.
SFP+ support for 10Gigabit speeds (Catalyst 2960-S only)
Support for up to 9000 bytes for frames that are bridged in hardware and up to 2000 bytes for frames
that are bridged by software
IEEE 802.3x flow control on all ports (the switch does not send pause frames).
Up to 20 Gb/s of forwarding rates in a Catalyst 2960-S switch stac k.
EtherChannel for enhanced fault tolerance and for pr oviding up to 8 Gb/s (Gigabit EtherChannel)
or 800 Mb/s (Fast 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.
Forwarding of Layer 2 packets at Gigabit line rate across the switches in the stack.
Forwarding of Layer 2 packets at Gigabit line rate
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.
Internet Group Management Protocol (IGMP) snooping for IGMP Versions 1, 2, and 3 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 pe riodic IGMP general query
messages.
IPv6 host support for basic IPv6 management
Multicast Listener Discovery (MLD) snooping to enable efficient distribution of IP version 6 (IPv6)
multicast data to clients and routers in a switched network
Note To use IPv6 features, the switch must be running the LAN Base image.
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.
Note To use MVR, the switch must be running the LAN Base image.
IGMP filtering for controlling the set of multicast groups to which hosts on a switch port can belong.
