Table 1 Product Features and Benefits

Feature	Benefit
Ease of use and deployment	• Auto-configuration of new stack units eliminates reconfiguration.
	• Dynamic Host Configuration Protocol (DHCP) auto-configuration of multiple
	switches through a boot server eases switch deployment.
	• Automatic Cisco IOS Software version checking and updating helps ensure that
	all stack members have the same software version.
	• Automatic QoS (AutoQoS) simplifies QoS configuration in voice-over-IP (VoIP)
	networks by issuing interface and global switch commands to detect Cisco IP
	phones, classify traffic, and enable egress queue configuration.
	• Master configuration management ensures that all switches are automatically
	upgraded when the master switch receives a new software version.
	• Auto-sensing on each non-SFP port detects the speed of the attached device and
	automatically configures the port for 10-, 100-, or 1000-Mbps operation, easing
	switch deployment in mixed 10, 100, and 1000BASE-T environments.
	• Auto-negotiating on all ports automatically selects half- or full-duplex
	transmission mode to optimize bandwidth.
	• Dynamic Trunking Protocol (DTP) enables dynamic trunk configuration across all
	switch ports.
	• Port Aggregation Protocol (PAgP) automates the creation of Cisco Fast
	EtherChannel groups or Gigabit EtherChannel groups to link to another switch,
	router, or server.
	• Link Aggregation Control Protocol (LACP) allows the creation of Ethernet
	channeling with devices that conform to IEEE 802.3ad. This feature is similar to
	Cisco EtherChannel technology and PAgP.
	• DHCP Relay allows a DHCP relay agent to broadcast DHCP requests to the
	network DHCP server.
	• IEEE 802.3z-compliant 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX,
	1000BASE-T and CWDM* physical interface support through a field-replaceable
	SFP module provides unprecedented flexibility in switch deployment.
	• To help ensure that the switch can be quickly connected to the network and can
	pass traffic with minimal user intervention, there is a default configuration stored
	in Flash.
	• Auto-MDIX (media-dependent interface cross-over) automatically adjusts
	transmit and receive pairs if an incorrect cable type (cross-over or
	straight-through) is installed.
Availability/Scalability
Superior redundancy for	• 1:N master redundancy allows each stack member to serve as a master, providing
fault backup	the highest reliability for forwarding.
	• Cisco CrossStack UplinkFast (CSUF) technology provides increased redundancy
	and network resiliency through fast spanning-tree convergence (less than 2
	seconds) across a switch stack with Cisco StackWise Technology.
	• Cross-Stack EtherChannel provides the ability to configure Cisco EtherChannel
	technology across different members of the stack for high resiliency.
	• IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) provides rapid spanning-tree
	convergence independent of spanning-tree timers and benefit of distributed
	processing.
	• Stacked units behave as a single spanning-tree node.
