Easy-to-Use Deployment and Control Features
●
User experience:
◦ IP service-level agreements (SLAs) enable customers to assure new business-critical IP applications, as
well as IP services that utilize data, voice, and video, in an IP network. This feature requires the IP
Services feature set.
◦ DHCP autoconfiguration of multiple switches through a boot server eases switch deployment.
◦ 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 help enable egress
queue configuration.
◦ Autonegotiation on all ports automatically selects half- or full-duplex transmission mode to optimize
bandwidth.
◦ Automatic media-dependent interface crossover (MDIX) automatically adjusts transmit and receive pairs
if an incorrect cable type (crossover or straight through) is installed.
●
Simplified configuration and connectivity:
◦ 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.
◦ 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.
◦ Cisco VLAN Trunking Protocol (VTP) Version 3 supports dynamic VLANs and dynamic trunk
configuration across all switches.
●
Efficient switch operation:
◦ Switching database manager (SDM) templates, VLAN template (specific to LAN Base license level), and
advanced template allow the administrator to automatically optimize the ternary content-addressable
memory (TCAM) 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.
◦ Stacking master configuration management with Cisco StackWise-480 technology helps make sure 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.
◦ Trivial File Transfer Protocol (TFTP) reduces the cost of administering software upgrades by
downloading from a centralized location.
◦ Network Timing Protocol (NTP) provides an accurate and consistent timestamp to all intranet switches.
