Chapter 1 Overview
Features
Performance Features
The switch ships with these performance features:
•
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 Mbps 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 1546 bytes routed frames, 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 32 Gbps of forwarding rates in a switch stack
•
EtherChannel for enhanced fault tolerance and for providing up to 8 Gbps (Gigabit EtherChannel)
or 800 Mbps (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 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
•
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
