Features and Benefits of Cisco Catalyst 2975 LAN Base Switch

Feature

Benefit

Ease of Use and

● Single configuration file for a stack of up to nine switches

Deployment

● Auto provisioning and software image update for new stack members

● Express Setup simplifies initial configuration with a web browser, eliminating the need for more

complex terminal emulation programs and CLI knowledge.

● IEEE 802.3af and Cisco prestandard PoE support comes with automatic discovery to detect a Cisco

prestandard or IEEE 802.3af endpoint and provide the necessary power without any user

configuration.

● Auto Install for configuration and Image update: Simplify management of large number of switches,

by automatically downloading specified configuration and image.

● DHCP autoconfiguration of multiple switches through a boot server eases switch deployment.

● Automatic QoS (Auto QoS) 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.

● Autosensing on each 10/100/1000 port detects the speed of the attached device and automatically

configures the port for 10- or 100- or 1000- Mbps operation, easing switch deployment in mixed 10-

and 100-Mbps and 1000-Mbps environments.

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

bandwidth.

● Dynamic Trunking Protocol (DTP) helps enable dynamic trunk configuration across all switch ports.

● Port Aggregation Protocol (PAgP) automates the creation of Cisco Fast EtherChannel

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 Server enables a convenient deployment option for the assignment of IP addresses in

networks that do not have without a dedicated DHCP server.

● DHCP Relay allows a DHCP relay agent to broadcast DHCP requests to the network DHCP server.

● 1000BASE-T, 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX, 1000BASE-BX, 100BASE-FX,

and CWDM physical interface support through a field-replaceable SFP module provides

unprecedented flexibility in switch deployment.

● The default configuration stored in flash memory helps ensure that the switch can be quickly

connected to the network and can pass traffic with minimal user intervention.

● Automatic medium-dependent interface crossover (Auto-MDIX) automatically adjusts transmit and

receive pairs if an incorrect cable type (crossover or straight-through) is installed on a copper port.

● Time-domain reflectometer (TDR) to diagnose and resolve cabling problems on copper ports.

● Configuration Rollback provides the capability to replace the current running configuration with any

saved Cisco IOS Software configuration file. This functionality can be used to revert to a previous

configuration state, effectively rolling back any configuration changes that were made since that

configuration file was saved.

● DHCP Auto Install (Boot Host DHCP) and Auto Image Update allows the switch to automatically

download a configuration file and IOS Software image.
