Operational Simplicity Features

●

Cisco AutoSecure provides a single-line CLI to enable base line security features (Port Security, DHCP

snooping, DAI). This feature simplifies security configurations with a single touch.

●

Dynamic Host Configuration Protocol (DHCP) autoconfiguration of multiple switches through a boot

server eases switch deployment.

●

Stacking master configuration management and Cisco FlexStack Plus technology helps ensure that all

switches are automatically upgraded when the master switch receives a new software version. Automatic

software version checking and updating help ensure that all stack members have the same software

version.

●

Autonegotiation on all ports automatically selects half- or full-duplex transmission mode to optimize

bandwidth.

●

Dynamic Trunking Protocol (DTP) facilitates 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.

●

Automatic media-dependent interface crossover (MDIX) automatically adjusts transmit and receive pairs

if an incorrect cable type (crossover or straight-through) is installed.

●

Unidirectional Link Detection Protocol (UDLD) and Aggressive UDLD allow unidirectional links caused

by incorrect fiber-optic wiring or port faults to be detected and disabled on fiber-optic interfaces.

●

Switching Database Manager (SDM) templates for access, routing, and VLAN deployment allow the

administrator to easily maximize memory allocation to the desired features based on deployment-specific

requirements.

●

Local Proxy Address Resolution Protocol (ARP) works in conjunction with Private VLAN Edge to

minimize broadcasts and maximize available bandwidth.

●

VLAN1 minimization allows VLAN1 to be disabled on any individual VLAN trunk.

●

Smart Multicast, with Cisco FlexStack-Plus technology, allows the Cisco Catalyst 2960-X Series to offer

greater efficiency and support for more multicast data streams such as video by putting each data packet

onto the backplane only once.

●

Internet Group Management Protocol (IGMP) Snooping for IPv4 and IPv6 MLD v1 and v2 Snooping

provide fast client joins and leaves of multicast streams and limit bandwidth-intensive video traffic to only

the requestors.

●

Multicast VLAN Registration (MVR) continuously sends multicast streams in a multicast VLAN while

isolating the streams from subscriber VLANs for bandwidth and security reasons.

●

Per-port broadcast, multicast, and unicast storm control prevents faulty end stations from degrading

overall systems performance.

●

Voice VLAN simplifies telephony installations by keeping voice traffic on a separate VLAN for easier

administration and troubleshooting.

●

Cisco VLAN Trunking Protocol (VTP) supports dynamic VLANs and dynamic trunk configuration across

all switches.
