Ease of use and
ease of deployment
• Autoconfiguration eases the deployment of switches in the network by automatically
configuring multiple switches across a network via a boot server.
• Autosensing on each Ethernet port] detects the speed of the attached device and
automatically configures the port for 10-, 100-, or 1000-Mbps operation, easing the
deployment of the switch in mixed 10, 100, and 1000BASE-T environments.
• Autonegotiating on all ports automatically selects half- or full-duplex transmission mode to
optimize bandwidth.
• Cisco VTP supports dynamic VLANs and dynamic trunk configuration across all switches.
• DTP enables dynamic trunk configuration across all ports in the switch.
• PAgP automates the creation of Cisco Fast EtherChannel or Gigabit EtherChannel groups,
enabling linking 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 is similar to Cisco EtherChannel and PAgP.
• The default configuration stored in Flash ensures that the switch can be quickly connected
to the network and can pass traffic with minimal user intervention.
