OL-13018-03
Automatic discovery of candidate switches and creation of clusters of up to 16 switches that can
–
be managed through a single IP address.
– Extended discovery of cluster candidates that are not directly connected to the command switch.
Cisco EnergyWise manages 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 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)
EtherChannel for enhanced fault tolerance and for providing 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
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 periodic 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
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
