Chapter 1 Configuration Overview
Feature Software Licensing
Ease-of-Deployment and Ease-of-Use Features
• Express Setup for quickly configuring a switch for the first time with basic IP inform ation, contact
information, switch and Telnet passwords, and Simple Network Management Protocol (SN MP)
information through a browser-based program. For more information about Exp ress Setup, see the
getting started guide.
• User-defined and Cisco-default Smartports macros for creating custom switch configurations for
simplified deployment across the network.
• A removable SD flash card that stores the Cisco IOS software image and configuration files for the
switch. You can replace and upgrade the switch without reconfiguring the software fe atures.
• An embedded Device Manager GUI for configuring and monitoring a single switch through a web
browser. For information about launching Device Manager, see the getting started guide. For more
information about Device Manager, see the switch online help.
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 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 1546 bytes routed frames, up to 9000 bytes for fra mes 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)
• Support for up to 6 EtherChannel groups
• Port Aggregation Protocol (PAgP) and Link Aggregation Control Protocol (LACP) for automatic
creation of EtherChannel links
• 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 Gr oup 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 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
• IGMP helper to allow the switch to forward a host request to join a multicast stream to a specific IP
destination address
• IGMP filtering for controlling the set of multicast groups to which hosts on a switch port can belong
