Monitoring Features, page 1-10
Express Setup for quickly configuring a switch for the first time with basic IP information, contact
information, switch and Telnet passwords, and Simple Network Management Protocol (SNMP)
information through a browser-based program. For more information about Express Setup, see the
getting started guide.
An embedded device manager GUI for configuring and monitoring a single switch through a web
browser. For information about launching the device manager, see the getting started guide. For more
information about the device manager, see the switch online help.
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 10/100/1000 Mb/s
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
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)
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
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
–
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
