Beneﬁt

• 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.

• 1:N master redundancy allows each stack member to serve as a master,

providing 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.
